Flag of Peru

Red represents the blood that was spilled for the fight. White represents Purity and Peace. However, the colours are also linked to the parihuanas, a red and white type of flamingo that General San Martín dreamed about during the revolution.[2]

The current colors of the Peruvian flag were taken of the design of San Martín and Torre Tagle. The reasons why red and white were chosen are unknown.

Official tones determined by Peruvian laws do not exist. However, there are some particular initiatives in approximated equivalents in multiple color models, some in tones close to crimson.[3]

Construction sheet.

The civil flag or ensign (bandera nacional) is used by citizens. It has no additions to the common form. It was changed several times; before 1950 it looked like the current national flag and was used as both the civil and the state flag, when General Manuel A. Odría removed the coat of arms from the flag and created the state and war flags. The Civil flag lacks coat of arms.

The state flag (pabellón nacional), used by state institutions, is marked with the coat of arms (Escudo de Armas). It is used during ceremonies in which the National Flag is hoisted in the presence of spectators (as opposed to a static, permanent flag). A form of this flag, the national standard (estandarte nacional) is used indoors by official and private institutions. It is used for the Government Palace, the United Nations, etc. It is also used by the Peru national football team.[5]

The war flag (bandera de guerra), similar to the state flag, is marked with the national shield (Escudo Nacional). It is flown by the Peruvian military and national police and is typically inscribed with the service, name and number of the unit flying it.

The naval jack (bandera de proa) is not based on the triband. It is a square flag, consisting of a white square with the coat of arms (Escudo de Armas) on a red field. It is used on warships, usually with the ensign of the highest-ranking officer on board above it.

Flag hoisted by Admiral Miller in October 1820.

During the Viceroyalty of Peru, the colonial-era Spanish flag flew over Peru. In 1820, during the struggle for independence, British-born General William Miller hoisted in Tacna the first flag that represented the emerging country. Though the original flag itself is now lost, it was described as navy blue, defaced with a golden sun representing Inti.

First republican flag, created by General José de San Martín.

The first flag of the Republic of Peru was created by General José de San Martín, and officially decreed on 21 October 1820. It is diagonally quartered, with white upper and lower fields, and the others red. The flag was defaced with an oval-shaped laurel crown in the center, surrounding a sun rising behind mountains by the sea. The symbolism of the flag's colors is uncertain, but according to Peruvian author Abraham Valdelomar, San Martín, having arrived on the coast of southern Pisco, was inspired by the colors of parihuanas, red-and-white flamingos. Historians of the early Peruvian Republic, such as Leguía y Martínez and Pareja Paz Soldán,[6] give a different explanation, suggesting that San Martín took the red from the flag of Chile and the white from the flag of Argentina, recognizing the provenance of the men of the liberation army. Historian Jorge Fernández Stoll thinks in 1820 San Martin was in favor of a constitutional monarchy, and he chose to use monarchical symbols and colors: Castile used the red and white colors for many years, the old flag of the viceroyalty the cross of Burgundy was red and white and the flag's diagonal lines mimicked the cross shape, the red color was the royal symbol of the mascaipacha of Inca kings and of the ensign of the Spanish king at that time.[7] The flag proved difficult to adopt due to its complex construction; without standardized measurements in place at the time, a triangular flag proved difficult to build.

Second design, by Torre Tagle.

In March 1822, José Bernardo de Tagle, Marquis of Torre Tagle and Supreme Delegate of the Republic, who replaced San Martín provisionally when the latter traveled to Guayaquil, decreed a new design for the flag. This consisted of a horizontal triband, with a white band between two red ones, and a golden Inti at the center, similar to the flag of Argentina. This modification was justified, according to Torre Tagle, by the inconvenience in the construction of the previous version, among other issues.

A problem came up on the battlefields: the resemblance with the Spanish flag, especially from far away, made the distinction between the armies difficult, which led to a new change to the flag.

Third design.

On 31 May 1822, Torre Tagle changed the flag's design again. The new version was a vertical triband, with red outer bands and a white middle band, with a golden sun representing Inti at the center.

Fourth flag, created in 1825.

On 25 February 1825, during Simón Bolívar's administration, the Constituent Congress changed the design of the flag by promulgating the law of national symbols. The fundamental change was the image of the sun for the brand new coat of arms, designed by José Gregorio Paredes and Francisco Javier Cortés.

In this way, the flag was definitely constituted by two vertical bands of red at the ends and white at the center, with the coat of arms at the center of the middle band.

Flag of the Peru–Bolivian Confederation, 1836–1839.

Flag of the Republic of South Peru, 1836–1839.

From 1836 to 1839, Peru was temporarily dissolved into the Republics of South Peru and North Peru, which joined Bolivia to form the Peru–Bolivian Confederation.

The South was formed first, thus adopting a new flag: a red vertical band on the left, with a golden sun and four small stars above (representing Arequipa, Ayacucho, Cuzco and Puno, the four groups of the republic), and the right side divided into an upper green band and a lower white one. The North kept the currency and all of the dissolved Peru, including its flag.

The flag of the Peru-Bolivian Confederation showed the coats of arms of Bolivia, South and North Peru, from left to right and slanted at different angles, on a red field, adorned by a laurel crown. Another version of the flag of the confederacy is offered by Flags of the World (https://www.crwflags.com/fotw/flags/xi_pb.html.

After the dissolution of the Confederation, the old Republic of Peru was restored to its 1836 composition, as were its national symbols.

In 1950, President Odría modified the national flag to its current form, removing the coat of arms from the civil flag, since it was used de facto, being easier to make. The national ensign and war flag were created for exclusive uses, each with a variant of the coat of arms, which was also changed slightly. These remain as the official flags today.[8]
