Union Jack

The Union Jack is normally twice as long as it is tall, a ratio of 1:2. In the United Kingdom, land flags are normally a ratio of 3:5; the Union Jack can also be made in this shape, but is 1:2 for most purposes. In 2008, MP Andrew Rosindell proposed a Ten Minute Rule bill to standardise the design of the flag at 3:5, but the bill did not proceed past the first reading.[44]

The three-component crosses that make up the Union Flag are sized as follows:[45]

• The red St George's Cross width is 1⁄5 of the flag's height with a 1⁄15 flag height fimbriation
• The white diagonal St Andrew's Cross width is 1⁄5 of the flag's height, visible on either side of the St Patrick's Cross in diagonals of 1⁄10 and 1⁄30 of the flag's height, respectively.
• The red diagonal St Patrick's Cross width is 1⁄15 of the flag's height. It is offset by 1⁄30 of the flag's height in an anti-clockwise direction. According to the official blazon of 1801, the white diagonal St Andrew's Cross is in fact counterchanged with the red diagonal of St Patrick's Cross. In this interpretation, the width of both saltires is 1⁄15 of the flag's height, with fimbriations of 1⁄30 of the flag's height on either side of the red saltire.

The crosses and fimbriations retain their thickness relative to the flag's height whether they are shown with a ratio of 3:5 or 1:2. Height here is the distance from top to bottom which in vexillology is termed width or breadth.

The Admiralty in 1864 settled all official flags at proportions of 1:2, but the relative widths of the crosses remained unspecified, with the above conventions becoming standardised in the 20th century.[46] In the 19th century, the Union flag was defined by the same blazon but could vary in its geometrical proportions.[47]

Although the most common ratio is 1:2, other ratios exist. The Royal Navy's flag code book, BR20 Flags of All Nations, states that both 1:2 and 3:5 versions are official.[48] The 3:5 version In this version, the innermost points of the lower left and upper right diagonals of the St Patrick's cross are cut off or truncated. The Garter King of Arms also suggests a ratio of 3:5 as the suitable proportion for a Union Flag flown on land.[49]

The Queen's Harbour Master's flag, like the Pilot Jack, is a 1:2 flag that contains a white-bordered Union Flag that is longer than 1:2. The jacks of ships flying variants of the Blue Ensign are square and have a square Union Flag in the canton.[48] The Queen's Colours of Army regiments are 36 by 43 inches (910 mm × 1,090 mm); on them, the bars of the cross and saltire are of equal width; so are their respective fimbriations, which are very narrow.[50]

In South Africa, the Union Jacks flown alongside the National Flag between 1928 and 1957 were 2:3 flags.

The colour specifications for the colours blue, red, and white are:[34]

All HEX, CMYK and RGB specifications for the Pantone colours are taken from the official Pantone website on the webpages of the corresponding colours. Although the colour schemes are official, not all of the colours are completely congruent. This is due to different specifications for different types of media (for example, screen and print).

The flag does not have reflection symmetry due to the slight pinwheeling of the St Patrick's and St Andrew's crosses, technically the counterchange of saltires. Thus, there is a correct side up. The flag does have two-fold rotational symmetry, though. The original specification of the Union Flag in the royal proclamation of 1 January 1801 did not contain a drawn pattern or express which way the saltires should lie; they were simply "counterchanged" and the red saltire fimbriated. Nevertheless, a convention was soon established which accords most closely with the description. The flag was deliberately designed with the Irish saltire slightly depressed at the hoist end to reflect the earlier union with Scotland, giving as it were seniority to the Saint Andrew's cross.

When statically displayed, the hoist is on the observer's left. To fly the flag correctly, the white of St Andrew is above the red of St Patrick in the upper hoist canton (the quarter at the top nearest to the flag-pole). This is expressed by the phrases wide white top and broadside up. An upside-down flag must be turned over to be flown correctly; rotating it 180 degrees will still result in an upside-down flag.

The first drawn pattern for the flag was in a parallel proclamation on 1 January 1801, concerning civil naval ensigns, which drawing shows the red ensign (also to be used as a red jack by privateers). As it appears in the London Gazette, the broad stripe is where expected for three of the four quarters, but the upper left quarter shows the broad stripe below.[32]

The Union Flag viewed upside down. The Union Flag is sometimes mistakenly flown upside down.

It is often stated that a flag upside down is a form of distress signal or even a deliberate insult. In the case of the Union Flag, the difference is subtle and is easily missed by the uninformed. It is often displayed upside down inadvertently—even on commercially-made hand waving flags.[53]

On 3 February 2009, the BBC reported that the flag had been inadvertently flown upside-down by the UK government at the signing of a trade agreement with Chinese premier Wen Jiabao. The error had been spotted by readers of the BBC News website who had contacted the BBC after seeing a photograph of the event.[54]

The first Union Flag from 1606

On 12 April 1606, a new flag to represent the regal union between England and Scotland was specified in a royal decree, according to which the flag of England (a red cross on a white background, known as St George's Cross), and the flag of Scotland (a white saltire on a blue background, known as the saltire or St Andrew's Cross), would be joined together,[10] forming the flag of Great Britain and first union flag:

By the King: Whereas, some differences hath arisen between Our subjects of South and North Britaine travelling by Seas, about the bearing of their Flagges: For the avoiding of all contentions hereafter. We have, with the advice of our Council, ordered: That from henceforth all our Subjects of this Isle and Kingdome of Great Britaine, and all our members thereof, shall beare in their main-toppe the Red Crosse, commonly called St George's Crosse, and the White Crosse, commonly called St Andrew's Crosse, joyned together according to the forme made by our heralds, and sent by Us to our Admerall to be published to our Subjects: and in their fore-toppe our Subjects of South Britaine shall weare the Red Crosse onely as they were wont, and our Subjects of North Britaine in their fore-toppe the White Crosse onely as they were accustomed.[57]

This royal flag was, at first, to be used only at sea on civil and military ships of both England and Scotland, whereas land forces continued to use their respective national banners.[58] Flying the national flag at the mainmast had signified the Admiral of the Narrow Seas (the English Channel) and confusion arose. In 1634, King Charles I restricted its use to Royal Navy ships.[15][28] After the Acts of Union 1707, the flag gained a regularised status as "the ensign armorial of the Kingdom of Great Britain", the newly created state. It was then adopted by land forces as well, although the blue field used on land-based versions more closely resembled that of the blue of the flag of Scotland.

Various shades of blue have been used in the saltire over the years. The ground of the current Union Flag is a deep "navy" blue (Pantone 280), which can be traced to the colour used for the Blue Ensign of the Royal Navy's historic "Blue Squadron". (Dark shades of colour were used on maritime flags on the basis of durability.) In 2003 a committee of the Scottish Parliament recommended that the flag of Scotland use a lighter "royal" blue (Pantone 300) (the Office of the Lord Lyon does not detail specific shades of colour for use in heraldry).

A thin white stripe, or fimbriation, separates the red cross from the blue field, in accordance with heraldry's rule of tincture where colours (like red and blue) must be separated from each other by metals (like white, i.e. argent or silver). The blazon for the old union flag, to be compared with the current flag, is azure, the cross saltire of St Andrew argent surmounted by the Cross of St George gules, fimbriated of the second.

The Protectorate Jack, flag used by The Protectorate from 1658 to 1660

The Kingdom of Ireland, which had existed as a personal union with England since 1541, was unrepresented in the original versions of the Union Jack.[58] However, the flag of the Protectorate from 1658 to 1660 was inescutcheoned with the arms of Ireland. These were removed at the Restoration, because Charles II disliked them.[59]

The original flag appears in the canton of the Commissioners' Ensign of the Northern Lighthouse Board. This is the only contemporary official representation of the pre-1801 Union Jack in the United Kingdom[60] and can be seen flying from their George Street headquarters in Edinburgh.

This version of the Union Jack is also shown in the canton of the Grand Union Flag (also known as the Congress Flag, the First Navy Ensign, the Cambridge Flag and the Continental Colours), the first widely used flag of the United States, slowly phased out after 1777.

The Union Jack flown on HMS Queen Charlotte, the Royal Navy flagship during the Glorious First of June in 1794. As is common for the period, the flag is an approximation of the Union Jack's proper specification.

Lord Howe's action, or the Glorious First of June, painted in 1795, shows a Union flying from HMS Queen Charlotte on the "Glorious First of June" 1794. The actual flag, preserved in the National Maritime Museum, is a cruder approximation of the proper specifications; this was common in 18th and early 19th century flags.[61][62]

The flag is also flown beside Customs House in Loftus Street, Sydney, to mark the approximate location at which Captain Phillip first raised the Union Jack, and claimed New South Wales in 1788. On the plaque it is referred to as the "Jack of Queen Anne".

The British Army's flag is the Union Jack, but in 1938, a "British Army Non-Ceremonial Flag" was devised, featuring a lion on crossed blades with the St Edward's Crown on a red background. This is not the equivalent of the ensigns of the other armed services but is used at recruiting and military or sporting events, when the army needs to be identified but the reverence and ceremony due to the regimental flags and the Union Jack would be inappropriate.

Slezer's Edinburgh Castle c. 1693 depicting the Scottish Union flag[63]

In objecting to the design of the Union Flag adopted in 1606, whereby the cross of Saint George surmounted that of Saint Andrew, a group of Scots took up the matter with John Erskine, 19th Earl of Mar, and were encouraged by him to send a letter of complaint to James VI, via the Privy Council of Scotland, which stated that the flag's design "will breid some heit and miscontentment betwix your Majesties subjectis, and it is to be feirit that some inconvenientis sail fall oute betwix thame, for our seyfaring men cannot be inducit to resave that flage as it is set down".[64] Although documents accompanying this complaint which contained drafts for alternative designs have been lost, evidence exists, at least on paper, of an unofficial Scottish variant, whereby the Scottish cross was uppermost. There is reason to think that cloth flags of this design were employed during the 17th century for unofficial use on Scottish vessels at sea.[65][66][67] This flag's design is also described in the 1704 edition of The Present State of the Universe by John Beaumont, which contains as an appendix The Ensigns, Colours or Flags of the Ships at Sea: Belonging to The several Princes and States in the World.[68]

On land, evidence confirming the use of this flag appears in the depiction of Edinburgh Castle by John Slezer, in his series of engravings entitled Theatrum Scotiae, c. 1693. Appearing in later editions of Theatrum Scotiae, the North East View of Edinburgh Castle engraving depicts the Scotch (to use the appropriate adjective of that period) version of the Union Flag flying from the Palace block of the Castle.[69] On The North Prospect of the City of Edenburgh engraving, the flag is indistinct.[70]

Scottish Union Flag depicted in the 1704 edition of The Present State of the Universe.

On 17 April 1707, just two weeks prior to the Acts of Union coming into effect, and with Sir Henry St George, the younger, the Garter King of Arms, having presented several designs of flag to Queen Anne and her Privy Council for consideration, the flag for the soon to be unified Kingdom of Great Britain was chosen. At the suggestion of the Scots representatives, the designs for consideration included that version of Union Jack showing the Cross of Saint Andrew uppermost; identified as being the "Scotts union flagg as said to be used by the Scotts".[71] However, the Queen and her Council approved Sir Henry's original effort, numbered "one".[71]

A manuscript compiled in 1785 by William Fox and in possession of the Flag Research Center includes a full plate showing "the scoth [sic] union" flag. This could imply that there was still some use of a Scottish variant before the addition of the cross of St Patrick to the Union Flag in 1801.[67]

A Union Jack flown aboard HMS Spartiate during the Battle of Trafalgar in 1805, which took place several years after the second Union Jack was adopted.

The current and second Union Jack dates from 1 January 1801 with the Act of Union 1800, which merged the Kingdom of Great Britain and the Kingdom of Ireland to form the United Kingdom of Great Britain and Ireland. The new design added a red saltire, the cross of Saint Patrick, for Ireland. This is counterchanged with the saltire of St Andrew, such that the red always follows the white clockwise. The arrangement has introduced a requirement to display the flag "the right way up" (see specifications for flag use above). As with the red cross, so too the red saltire is separated by a white fimbriation from the blue field.[34] This fimbriation is repeated for symmetry on the white portion of the saltire, which thereby appears wider than the red portion. The fimbriation of the cross of St George separates its red from the red of the saltire.

Apart from the Union Jack, Saint Patrick's cross has seldom been used to represent Ireland, and with little popular recognition or enthusiasm; it is usually considered to derive from the arms of the powerful FitzGerald family rather than any association with the saint.[72]

When the Anglo-Irish Treaty was concluded on 6 December 1921 and the creation of the new Irish Free State was an imminent prospect, the question arose as to whether the cross of Saint Patrick should remain in the Union Jack. The New York Times reported that on 22 January 1922:

The cross of Saint Patrick was incorporated into the Union Jack in 1801 to represent Ireland. However, the imminent creation of the Irish Free State in 1922 saw some people question the continued placement of the cross on the Union Jack.

At the College of Arms it was stated that certain modifications were under consideration and that if any action were taken it would be done by the King in Council. No parliamentary action would be necessary. Heraldry experts say that alterations in arms are very expensive. Some years ago there was a demand from Irish quarters that the blue ground of the golden harp on the royal standard should be changed to green. It was then estimated that the alteration would cost at least £2,000,000. To remove all reference to Ireland from the present Union Jack and Royal Arms would be vastly more expensive.[73]

There was some speculation on the matter in British dominions also, with one New Zealand paper reporting that:

...the removal of the cross of St. Patrick Cross after 120 years will transform the appearance of the flag. It will certainly become a flag under which great victories were won in the seventeenth and eighteenth centuries, but to most minds the sentimental loss will be great. Probably it will be found that the deletion is not absolutely necessary. Other possible changes include the abolition of the title of the United Kingdom, and the removal of the harp from the Royal Standard and the Coat of Arms, and the substitution of the Ulster emblem.[74]

However, the fact that it was likely that Northern Ireland would remain in the United Kingdom gave better grounds for keeping the cross of St. Patrick in the Union Jack. In this regard, Sir James Craig, the Prime Minister of Northern Ireland remarked in December 1921 that he and his government were "glad to think that our decision [to remain part of United Kingdom] will obviate the necessity of mutilating the Union Jack."[75] Though remaining within the United Kingdom, the new government of Northern Ireland dispensed with the St Patrick's Saltire in favour of a new flag derived from the coat-of-arms of the Burkes, Earls of Ulster, and quite similar to England's St George's Cross.

Ultimately, when the British home secretary was asked on 7 December 1922 (the day after the Irish Free State was established) whether the Garter King of Arms was "to issue any Regulations with reference to the national flag consequent to the passing of the Irish Free State Constitution Act", the response was no and the flag has never been changed.[76]

A Dáil question in 1961 mooted raising the removal of the cross of St Patrick with the British government; Frank Aiken, the Irish Minister for External Affairs, declined to "waste time on heraldic disputations".[77]

In 2003, a private individual started a campaign – dubbed "reflag" or "Union Black" – to introduce black stripes in the Union Jack in order to represent the increasing diversity in the United Kingdom. The proposal was universally met with opposition and was denounced by MSP Phil Gallie as "ridiculous tokenism [that] would do nothing to stamp out racism".[78]

One suggested redesign of the Union Jack with the red dragon from the flag of Wales added in the centre

The lack of any Welsh symbol or colours in the flag is a result of Wales having been considered an integral part of the Kingdom of England at the time the flag of Great Britain was created in 1606. Since there is no Welsh element in the Union Jack, Wrexham's Labour MP Ian Lucas proposed on 26 November 2007 in a House of Commons debate that the Union Flag be combined with the Welsh flag to reflect Wales's status within the UK, and that the red dragon be added to the Union Flag's red, white, and blue pattern.[79] He said the Union Jack currently only represented the other three UK nations, and Minister for Culture, Creative Industries and Tourism Margaret Hodge conceded that Lucas had raised a valid point for debate. She said, "the Government is keen to make the Union Flag a positive symbol of Britishness reflecting the diversity of our country today and encouraging people to take pride in our flag." This development sparked design contests with entries from all over the world.[80]

In the run-up to the 2014 Scottish independence referendum, various non-official suggestions were made for how the flag could be redesigned without the St Andrew's Cross if Scotland left the Union. However, as Scotland voted against independence, the issue did not arise.[81][82]

Vertical displays of the Union Flag during a parade for Elizabeth II's official birthday

In July 2007, then-Prime Minister Gordon Brown unveiled plans to have the Union Flag flown more often from government buildings.[90] While consultation on new guidelines was under way, the decision to fly the flag could be made by each government department. In March 2021, the UK government published new guidance for the Union Flag to be flown all year round on UK government buildings, unless another flag is being flown – such as another national flag of the UK, or a county flag, or other flags to mark civic pride.[91]

Previously, the flag was generally only flown on public buildings on days marking the birthdays of members of the royal family, the wedding anniversary of the monarch, Commonwealth Day, Accession Day, Coronation Day, the monarch's official birthday, Remembrance Sunday, and on the days of the State Opening and prorogation of Parliament. Non-government organisations were (and are) permitted to fly the Union Flag whenever they choose.

The last specified set of flag days where the Union Flag should be flown from government buildings throughout the UK were:[92]

In addition, the Union Flag was to be flown on the following days in specified areas:[92]

A Union Jack at half-mast after the death of Elizabeth II in September 2022

The Union Flag is flown at half mast from the announcement of the death of the sovereign (save for Proclamation Day), or upon command of the sovereign.[93]

On 30 November, (St Andrew's Day), the Union Flag can be flown in Scotland only where a building has more than one flagpole—on this day the Saltire will not be lowered to make way for the Union Flag if there is only one flagpole.[94] This difference arose after Members of the Scottish Parliament complained that Scotland was the only country in the world that could not fly its national flag on its national day. However, on 23 April, St George's Day, it is the Union Flag of the United Kingdom that is flown over UK government offices in England.[95]

The Union Flag has no official status in the United Kingdom, and there are no national regulations concerning its use or prohibitions against flag desecration. In Northern Ireland, the Flags Regulations (Northern Ireland) 2000 provide for the flying of the flag on government buildings on certain occasions, when it is flown half-mast, and how it is displayed with other flags.[96]

A folded Union Flag with a tam o' shanter on top of it

The Flags and Heraldry Committee, an all-party parliamentary group lobbying for official standards, cooperated with the Flag Institute in 2010 to publish a set of recommended guidelines for the flag's display and use as a symbol.[97]

There is no specific way in which the Union Flag should be folded as there is with the United States Flag. It is usually folded rectilinearly, with the hoist on the outside, to be easily reattached to the pole.[97][98]

Royal Navy Stores Duties Instructions, article 447, dated 26 February 1914, specified that flags condemned from further service use were to be torn up into small pieces and disposed of as rags (ADM 1/8369/56), not to be used for decoration or sold. The exception was flags that had flown in action: these could be framed and kept on board, or transferred to a "suitable place", such as a museum (ADM 1/8567/245).[34]

According to the UK Flag Protocol, the order of precedence of flags in the United Kingdom is: the Royal Standards, the Union Flag, the flag of the host country (England, Scotland and Wales etc.), the flags of other nations (in English alphabetical order), the Commonwealth Flag, the county flags, the flags of cities or towns, the banners of arms, and the house flags.[99]

The Union Jack and the flag of Bermuda flown from Fort St. Catherine in Bermuda, 2016

The Union Jack is the national flag of the British Overseas Territories, which are parts of the British realm with varying degrees of local autonomy. Most populated administrative regions and territories of the United Kingdom have been granted a unique flag for the locality, usually the Blue ensign or Red ensign defaced with the distinguishing arms of the territory. All fly the Union Jack in some form, with the exception of Gibraltar (other than the government ensign).

The Crown Dependencies, unlike the British Overseas Territories, are legally not part of the United Kingdom, and the Union Jack is not an official flag there. Outside the UK, the Union Jack is usually part of a special ensign in which it is placed in the upper left hand corner of a blue field, with a signifying crest in the bottom right. When the Union Jack and the territorial flag are flown together, the national flag is always arranged to take precedence over the territorial flag.[100]

The Australian ensign and Union Jack hung vertically from Australia's Parliament House, 1931

The Union Flag was used as a flag of Australia until 1953, although the Australian blue ensign saw use as a governmental flag of Australia, and an informal national flag of the country since the early 20th century.[101] From 1911 to 1956, schools in South Australia were required to fly the Union Jack for the "national salute".[102]

In 1953, the Australian blue ensign was named the national flag of Australia, through the Flags Act 1953.[102] Although the Australian blue ensign replaced the Union Jack as the flag of Australia, Australian prime minister Robert Menzies told Australians that the Union Flag would be flown together with the Australian national flag "on notable occasions".[102] Section 8 of that Flag Act also specified that the formalization of the Australian blue ensign as the national flag did "not affect the right or privilege of a person to fly the Union Jack."[103] The Union Jack continued to see informal use as a flag of Australia for a period thereafter, although by the 1980s, the majority of Australians viewed the Australian blue ensign as the national flag as opposed to the Union Jack.[104]

The Union Jack was the official national flag of Canada until 1965 when it was replaced in that role by the Maple Leaf flag.[105][106] Since 1965, the Union Jack in Canada is used as an authorised symbol to represent Canada's "membership in the Commonwealth of Nations and its allegiance to the Crown".[107]

The Union Flag and the U.S. flag at the Canada-U.S. border, 1899. The Union Flag was the formal flag of Canada until 1965.

The Union Jack has been used in a variety of colonies in British North America since its official adoption in 1707, In 1867, the British North American colonies of New Brunswick, Nova Scotia, and the Province of Canada were united to form the Canadian Confederation; with the Union Jack being retained as the official flag of the new "confederation".[105]

In addition to the Union Jack, during the late 19th century, a red ensign defaced with the arms of Canada was also used as an informal flag of Canada. The defaced red ensign, later known as the Canadian Red Ensign, was eventually authorised for official use as the country's civil ensign in 1892. Although the Canadian Red Ensign was only formally authorised as a civil ensign, it was also viewed as a de facto national flag, as it was a uniquely Canadian symbol.[105]

In 1964, Canadian Prime Minister Lester B. Pearson introduced plans to replace the Union Flag with a new national flag, spurring the Great Canadian flag debate.[105] A new national flag, the Maple Leaf, was approved by the parliament of Canada on 17 December 1964.[105] However, on the following day, the Canadian parliament passed another resolution that designated the Union Flag as the Royal Union Flag and authorised its official use as the symbol of the country's membership in the Commonwealth of Nations and its allegiance to the Crown.[107] The move was a concession given to those who preferred to adopt the Canadian Red Ensign as a formal national flag. On 15 February 1965, the maple leaf flag formally replaced the Union Flag as the flag of Canada following an official proclamation by Elizabeth II,[105] with the Royal Union Flag becoming an official ceremonial flag.[107]

The Royal Union Flag next to the flag of Canada during a Remembrance Day parade in Stirling, Ontario, 2009

The Union Flag was also the formal flag for the Dominion of Newfoundland, a separate dominion of the British Empire from 1907 to 1949. Newfoundland retained the Union Flag as the province's official flag after it joined the Canadian confederation in 1949. In 1980, the flag of Newfoundland was adopted as the new provincial flag, with the design for the new flag of Newfoundland being derived from the Union Flag.

The parliamentary resolution passed on 18 December 1964 assigned two purposes for the Royal Union Flag: a flag representing the United Kingdom and an official ceremonial flag of Canada.[106] When used to represent the United Kingdom, the flag takes precedence before the flag of a Canadian province or territory. However, when the flag is used as a ceremonial flag of Canada, the flag of a Canadian province or territory takes precedence before the Royal Union Flag.[106]

Hartland Covered Bridge in 2008. The Royal Union Flag on top of the bridge is positioned to the right of the flag of Canada and the provincial flag, in accordance with protocol.

The parliamentary resolution requires the Royal Union Flag to be flown alongside the national flag of Canada (if there are at least two flag poles available) on federal properties on Commonwealth Day, Victoria Day (the monarch's official birthday in Canada), 11 December (the anniversary of the enactment of the Statute of Westminster, 1931), and when otherwise instructed to do so by the National Defence Headquarters.[107][106] The Royal Union Flag may also be formally flown alongside the flag of Canada at federal locations in Canada for ceremonies, anniversaries, and other events relating to the Canadian Armed Forces or other forces in the Commonwealth.[107][106]

Items and properties that the parliamentary resolution applies to includes buildings operated by the federal government, military installations, federally-operated airports, at the masthead of Royal Canadian Navy ships within Canadian waters, and other appropriate establishments. The requirement for federal properties to fly the Royal Union Flag applies only when there are two or more flagpoles on the property, to ensure that the national flag of Canada is not taken down in place of the Royal Union Flag.[107][106][108]

The 1888–89 New Zealand Native football team pose in front of the flag of the United Tribes of New Zealand and the Union Jack, 1889

The Union Flag became the flag of New Zealand after the Treaty of Waitangi was signed in February 1840, replacing the flag used by the United Tribes of New Zealand.[109] The issue of flying the flag of the United Tribes alongside the Union Jack, as a symbol of their equal standing with the colonial government, served as a factor that led to the Flagstaff War, led by Ngāpuhi chief Hōne Heke.[109] British maritime flags were used by New Zealand vessels until 1865.[109] After the passage of the Colonial Naval Defence Act 1865, vessels of the New Zealand government used a defaced blue ensign issued by the colonial government.

The current national flag of New Zealand was given official standing under the New Zealand Ensign Act in 1902, replacing the Union Flag.[109][110] However, the Union Flag continued to see tandem use with the national flag of New Zealand into the 1950s.[109]

The Union Jack was used as the flag of a variety of colonies in South Africa since 1795. The Union Jack was retained as the official flag of the Union of South Africa after its formation in 1910. In addition to the Union Jack, from 1910 to 1928, the South African Red Ensign was also treated as an unofficial flag of the union.

Proposals to adopt a national flag were made during the 1920s. In 1927, the Union Nationality and Flag Act was passed by the Parliament of South Africa, which named both the Union Jack and the Oranje, Blanje, Blou flag of South Africa as the flags of the union, both co-equal in status. The Oranje, Blanje, Blou flag also incorporated the Union Jack in its design, alongside the flag of the Orange Free State and the flag of the South African Republic. The Union Jack was to be flown alongside the Oranje, Blanje, Blou at principal government buildings in the capitals, at Union ports, on government offices abroad, and at such other places as the government might determine.[111][112] The act went into effect on 31 May 1928.

Instructions issued in 1931 confirmed the places where both flags were to be flown. In addition to those already mentioned, they were the Union Buildings in Pretoria, the head offices of the four provincial administrations, the supreme courts, certain magistrates' courts, customs houses, and three buildings in Durban (the general post office, the railway station, and the local military district headquarters).[113][112] Under these arrangements, the Union Jack was subordinate to the Oranje, Blanje, Blou. As the two flags had to be the same size, it meant that the Union Jack was made in the ratio 2:3 rather than the usual 1:2.[113][112]

This dual arrangement continued until 1957, when the Flags Amendment Act was passed naming the Oranje, Blanje, Blou as the sole flag of South Africa.[114] The Oranje, Blanje, Blou was replaced by the flag of South Africa in 1994 as the country's national flag.

Several individuals residing in countries not a part of the Commonwealth of Nations have adopted the Union Flag as a flag of protest. After the British referendum on membership of the European Union resulted in a vote to leave, the Union Flag had become a symbol of euroscepticism in Italy. In August 2016, many local businesses along the Italian riviera hoisted the flags as a protest against the implementation of the Services in the Internal Market Directive 2006.[115]

The Union Flag was formerly used in Hong Kong when it was a British Dependent Territory. Official use of the Union Flag and the British colonial Hong Kong flag ceased following the handover of Hong Kong to China in July 1997. In the 2010s, the Union Flag, along with the colonial flag of Hong Kong began to see use by supporters of the pro-democracy camp during the 2014 Hong Kong protests, and the 2019–20 Hong Kong protests.[116][117] The flag has been displayed at other pro-democracy events in Hong Kong, including the new year marches and the 1 July marches. Members of the Hong Kong Autonomy Movement, the Hong Kong independence movement and Hong Kong localists have been seen wielding the Union Flag or the colonial flag of Hong Kong.[118]

However, the meaning behind the use of the flags by pro-democracy protestors, including the Union Flag, remains disputed with protestors citing a variety of reasons for flying it.[119] Some pro-democracy protestors that flew foreign flags, including the Union Flag, did so in an effort to attract international media attention to the protests, while others did so in an effort to irritate the central government of China.[119][120] The Union Flag, in addition to other foreign flags, were also used by some protestors to illustrate their desire for Hong Kong to be an "international city"; whereas others used the flag simply as a generic symbol of freedom.[119][121][122]

Some specifically flew the Union Flag and the colonial flag of Hong Kong, nostalgic of the "values" of the previous colonial government, namely "personal freedoms, rule of law, [and] clean governance".[116][118] Other pro-democracy protestors choose to use the Union Flag and the colonial flag of Hong Kong in an effort to call upon the British government to declare that China had failed to uphold the Sino-British Joint Declaration.[119] Several Hongkongers that hold British National (Overseas) passports who used the flag during the protests were doing so as a call to the British government to grant British National (Overseas) the right to abode in the United Kingdom.[119] Although a small number of Hongkongers seek direct British intervention into the matter, the majority of those that used the Union Flag or the colonial flag of Hong Kong during the protests do not hold such beliefs.[118]

The use of foreign flags at the protests, including the Union Flag, has been cited multiple times by the central government of China as evidence for their claim that foreign interference is steering the protests in Hong Kong against the central government.[119] Conversely, several protestors in the pro-democracy camp have also been criticized the use of foreign flags, who view their use as reinforcing the claims made by the central government of China.[119]

As the national flag of the entire British Realm, the Union Flag was found in the canton (upper flagpole-side quarter) of the flags of many colonies of Britain, while the field (background) of their flags was the colour of the naval ensign flown by the particular Royal Navy squadron that patrolled that region of the world. Nations and colonies that have used the Union Flag at some stage have included Aden, Basutoland (now Lesotho), Barbados, Bechuanaland (now Botswana), Borneo, Burma, Canada, Ceylon (now Sri Lanka), Cyprus, Dominica, British East Africa (Kenya Colony), Gambia, Gold Coast (Ghana), Grenada, Guiana, Hong Kong, Jamaica, Labuan (Malaysia), Lagos, Malta, Mauritius, Nigeria, Palestine, Penang (Malaysia), Rhodesia (now Zimbabwe), Sierra Leone, Singapore, Somaliland, South Africa, Anglo-Egyptian Sudan, Pre-partitioned India (present-day India, Pakistan, Bangladesh, and Myanmar), Tanganyika, Trinidad and Tobago, Uganda, the United States, and Weihaiwei. As former British Empire nations were granted independence, these and other versions of the Union Flag were decommissioned. The most recent decommissioning of the Union Flag came on 1 July 1997, when the former Dependent Territory of Hong Kong was handed over to the People's Republic of China.

National flags of sovereign states whose design incorporates a Union Jack in their canton

Four former British colonies in Oceania which are now independent countries incorporate the Union Jack as part of their national flags: Australia, New Zealand and Tuvalu, which have retained the monarchy; and Fiji, which abolished the monarchy in 1987.

In former British colonies, the Union Jack was used interchangeably with informal flags of the territory for significant parts of their colonial early history. The Union Flag was used as the flag of Canada until it was re-adopted as a ceremonial flag, and the Maple Leaf flag made the official national flag in 1965. In addition to being an official ceremonial flag, the Union Flag also defaces the flags of a number of Canadian provinces, including British Columbia, Manitoba, and Ontario. Newfoundland and Labrador uses a flag that was derived from the Union Flag, with the Union Jack serving as the flag of Newfoundland until 1980. The Union Flag, and flags defaced with the Union Flag in its canton, like the Canadian Red Ensign, continue to see use in Canada in a private capacity. The pre-1801 Union Flag also sees limited use by private organizations, most notably the United Empire Loyalists Association of Canada.[123]

Along with the national flag, many other Australian flags retain the use of the Union Jack, including the Royal Australian Navy Ensign (also known as the Australian White Ensign), the Royal Australian Air Force Ensign, the Australian Red Ensign (for use by merchant and private vessels), and the Australian Civil Aviation Ensign. The flags of all six Australian States retain the Union Jack in the canton, as do some regional flags such as the Upper and Lower Murray River Flags. The Vice-Regal flags of the State Governors also use the Union Jack. While the Flags Act 1953 states that Australians still have the "right or privilege" to fly the Union Jack after the introduction of the Australian National Flag, usage of the Union Jack by itself is unusual.

The Basque Country's flag, the Ikurriña, is also loosely based on the Union Jack, reflecting the significant commercial ties between Bilbao and Britain at the time the Ikurriña was designed in 1894. The Miskito people sometimes use a similar flag that also incorporates the Union Jack in its canton, due to long periods of contact in the Mosquito Coast.

Former national flags that incorporated the Union Jack in their design

The Union Jack was used by the United States in its first flag, the Grand Union Flag. This flag was of a similar design to the one used by the British East India Company. Hawaii, a state of the United States but located in the central Pacific, incorporates the Union Jack in its state flag. According to one story, the King of Hawaii asked the British mariner, George Vancouver, during a stop in Lahaina, what the piece of cloth flying from his ship was. Vancouver replied that it represented his king's authority. The Hawaiian king then adopted and flew the flag as a symbol of his own royal authority not recognising its national derivation. Hawaii's flag represents the only current use of the Union Jack in any American state flag.

Also in the United States, the Union Flag of 1606 is incorporated into the flag of Baton Rouge, the capital city of Louisiana. Baton Rouge was a British colony from the time of the Seven Years' War until the end of the American Revolutionary War, when it was captured by Spanish forces. Symbols from the colonial powers France and Spain are also incorporated into the Baton Rouge flag. Taunton, Massachusetts, uses a flag with the old style Union Flag by a resolution on 19 October 1974. Likewise, Westmoreland County, Pennsylvania, has been known to fly a flag containing the King's Colours since 1973.[124]

The Union Jack also appeared on both the 1910–1928 and 1928–1994 flags of South Africa. The 1910–1928 flag was a Red Ensign with the Union coat of arms in the fly. The 1928–1994 flag, based on the Prinsenvlag and commonly known as the oranje-blanje-blou (orange-white-blue), contained the Union Jack as part of a central motif at par with the flags of the two Boer republics of the Orange Free State and Transvaal. To keep any one of the three flags from having precedence, the Union Jack is spread horizontally from the Orange Free State flag towards the hoist; closest to the hoist, it is in the superior position but since it is reversed it does not precede the other flags.

The flag of the Municipal Council of Shanghai International Settlement in 1869 contained multiple flags to symbolize the countries have participated in the creation and management of this enclave in the Chinese city of Shanghai. The Union Jack was contained as part of top left hand shield and close to the flags of the United States and France, there was also contained the flag of Prussia nearby, but it was removed around 1917.

The flag of the Chilean city of Coquimbo features the Union Jack, owing to its historical commercial links to Britain.

The Union Flag can be found in the canton of several of the ensigns flown by vessels and aircraft of the United Kingdom and its overseas territories. These are used in cases where it is illegal to fly the Union Flag, such as at sea from a ship other than a British warship. Normal practice for British ships is to fly the White ensign (Royal Navy), the Red ensign (Merchant and private boats) or the Blue ensign (government departments and public corporations). Similar ensigns are used by other countries (such as New Zealand and Australia) with the Union Flag in the canton. Other Commonwealth countries (such as India and Jamaica) may follow similar ensign etiquette as the UK, replacing the Union Flag with their own national flag.

A Pilot Jack, a flag design that has a Union Jack at its centre, with a white border around it

The flag in a white border occasionally seen on merchant ships was sometimes referred to as the Pilot Jack. It can be traced back to 1823 when it was created as a signal flag, but not intended as a civil jack. A book issued to British consuls in 1855 states that the white bordered Union Flag is to be hoisted for a pilot. Although there was some ambiguity regarding the legality of it being flown for any other purpose on civilian vessels, its use as an ensign or jack was established well in advance of the 1864 Act that designated the Red Ensign for merchant shipping. In 1970, the white-bordered Union Flag ceased to be the signal for a pilot, but references to it as national colours were not removed from the current Merchant Shipping Act and it was legally interpreted as a flag that could be flown on a merchant ship, as a jack if desired. This status was confirmed to an extent by the Merchant Shipping (Registration, etc.) Act 1993 and the consolidating Merchant Shipping Act 1995 which, in Section 4, Subsection 1, prohibits the use of any distinctive national colours or those used or resembling flags or pendants on Her Majesty's Ships, "except the Red Ensign, the Union flag (commonly known as the Union Jack) with a white border", and some other exceptions permitted elsewhere in the Acts. However, Section 2 regards the "British flag", and states that "The flag which every British ship is entitled to fly is the Red Ensign (without any defacement or modification) and, subject to (a warrant from Her Majesty or from the Secretary of State, or an Order of Council from her Majesty regarding a defaced Red Ensign), no other colours."[125] The Flag Institute listed the white bordered Union Flag as "Civil Jack".[24]

The former flag of the Hudson's Bay Company, used from 1801 to 1965.

The Hudson's Bay Company (HBC) was one of a few non-government institutions using the Union Jack in part of the flag. HBC rival North West Company had a similar flag as well. The HBC Red Ensign is no longer in use in 1965 and replaced with a corporate flag featuring the company's coat of arms.

The unofficial British Empire flag incorporated dominion symbols

An unofficial flag for the British Empire was created around 1910 due to a belief that the Union Jack itself no longer sufficiently represented dominions such as Canada, which were beginning to adopt their own unique symbols. The flag was similar in design to a White Ensign, which features the Union Jack in the canton. In the other quadrants were the coats of arms of Canada, Australia, and South Africa. The four stars forming the Crux over Saint George's Cross represented New Zealand, and the Star of India was featured prominently in the middle. Civilians often flew Empire flags for patriotic events such as coronations, Empire Day, and the British Empire Exhibition.[126] It is still flown on special occasions at the Dangarsleigh War Memorial.[127]

The Union Jack is the third quarter of the 1939 coat of arms of Alabama, which is used on the flag of the governor of Alabama, representing British sovereignty over the state prior to 1783. The version used is the modern flag, whereas the 1707 flag would have been used in colonial Alabama.

In the former International Settlement of Kulangsu the Kulangsu Municipal Police had a badge contained multiple flags, including the Union Flag. Then the badge is incorporated in their police flag.[128]

Commonly the Union Flag is used on computer software and Internet pages as an icon representing a choice of the English language where a choice among multiple languages may be presented to the user, though the American flag is also sometimes used for this purpose. The flag has been embroidered on various Reebok equipment as a mark of the brand's British origin,[135] and the Reebok Union Jack has been referred to as a brand icon.[136] Many music artists have used the Union Jack, ranging from rock artists the Rolling Stones, the Who, the Jam, Sex Pistols, the Stone Roses, David Bowie, John Lennon, Paul McCartney, Freddie Mercury, Morrissey, Oasis, Iron Maiden, and Def Leppard, to the pop girl group the Spice Girls.

Branding designs that have incorporated the Union Jack

British Airways painted a cropped Union Flag on their tail fins until 1984, from 1997 on, they started painting a stylised, fluttering Union flag on tail fins, nicknamed Chatham Dockyard Union Flag. The coat of arms of British Airways also features the escutcheon cropped from the Union Flag.[137] British Airways used the coat of arms on their aircraft via the Landor livery between 1984–1997 and added back in 2011, also used as cap badge for pilots or in advertisements.[138][139][140][141]

The BMW Mini tail lights are shaped after the Union Jack.[142]
