The Industrial Revolution was the major technological, socioeconomic, and cultural change in late 18th and early 19th century that began in Britain and spread throughout the world. During that time, an economy based on manual labour was replaced by one dominated by industry and the manufacture of machinery. It began with the mechanisation of the textile industries and the development of iron-making techniques, and trade expansion was enabled by the introduction of canals, improved roads, and then railways. The introduction of steam power (fuelled primarily by coal) and powered machinery (mainly in textile manufacturing) underpinned the dramatic increases in production capacity.[5] The development of all-metal machine tools in the first two decades of the 19th century facilitated the manufacture of more production machines for manufacturing in other industries.

The date of the Industrial Revolution is not exact. Eric Hobsbawm held that it "broke out" in the 1780s and was not fully felt until the 1830s or 1840s,[6] while T. S. Ashton held that it occurred roughly between 1760 and 1830 (in effect the reigns of George III, The Regency, and George IV).[7]

The effects spread throughout Western Europe and North America during the 19th century, eventually affecting the majority of the world. The impact of this change on society was enormous and is often compared to the Neolithic Revolution, when mankind developed agriculture and gave up its nomadic lifestyle.[8]

The First Industrial Revolution gave way to the Second Industrial Revolution around 1850, when technological and economic progress gained momentum with the development of steam-powered ships and railways, and later in the nineteenth century with the internal combustion engine and electric power generation.

It has been argued that GDP per capita was much more stable and progressed at a much slower rate until the industrial revolution and the emergence of the modern capitalist economy, and that it has since increased rapidly in capitalist countries.[9]

The Napoleonic era is a period in the History of France and Europe. It is generally classified as the fourth stage of the French Revolution, the first being the National Assembly, the second being the Legislative Assembly, and the third being the Directory. The Napoleonic era begins roughly with Napoleon's coup d'état, overthrowing the Directory and ends at the Hundred Days and his defeat at Waterloo (November 9 1799 – June 28 1815). The Congress of Vienna soon set out to restore Europe to pre-French Revolution days.

Historians sometimes define a nineteenth century historical era stretching from 1815 (the Congress of Vienna) to 1914 (the outbreak of the First World War); alternatively, Eric Hobsbawm defined the "long nineteenth century" as spanning the years 1789 to 1914.

During this century, the Spanish, Portuguese, and Ottoman Empires began to crumble and the Holy Roman and Mughal Empires ceased.

Following the Napoleonic Wars, the British Empire became the world's leading power, controlling one quarter of the World's population and one third of the land area. It enforced a Pax Britannica, encouraged trade, and battled rampant piracy.

Slavery was greatly reduced around the world. Following a successful slave revolt in Haiti, Britain forced the Barbary pirates to halt their practice of kidnapping and enslaving Europeans, banned slavery throughout its domain, and charged its navy with ending the global slave trade. Slavery was then abolished in Russia, America, and Brazil (see Abolitionism).

Following the abolition of the slave trade, and propelled by economic exploitation, the Scramble for Africa was initiated formally at the Berlin West Africa Conference in 1884–1885. All the major European powers laid claim to the areas of Africa where they could exhibit a sphere of influence over the area. These claims did not have to have any substantial land holdings or treaties to be legitimate. The French gained major ground in West Africa, the British in East Africa, and the Portuguese and Spanish at various points throughout the continent, while Leopold II of Belgium was able to retain his personal fiefdom, Congo.

Electricity, steel, and petroleum fuelled a Second Industrial Revolution which enabled Germany, Japan, and the United States to become great powers that raced to create empires of their own. However, Russia and China failed to keep pace with the other world powers which led to massive social unrest in both empires.

Above all, the 20th century is distinguished from most of human history in that its most significant changes were directly or indirectly economic and technological in nature.

Economic development was the force behind vast changes in everyday life, to a degree which was unprecedented in human history. The great changes of centuries before the 19th were more connected with ideas, religion or military conquest, and technological advance had only made small changes in the material wealth of ordinary people. Over the course of the 20th century, the world's per-capita gross domestic product grew by a factor of five , much more than all earlier centuries combined (including the 19th with its Industrial Revolution). Many economists make the case that this understates the magnitude of growth, as many of the goods and services consumed at the end of the century, such as improved medicine (causing world life expectancy to increase by more than two decades) and communications technologies, were not available at any price at its beginning. However, the gulf between the world’s rich and poor grew much wider than it had ever been in the past, and the majority of the global population remained in the poor side of the divide.

Still, advancing technology and medicine has had a great impact even in the Global South. Large-scale industry and more centralized media made brutal dictatorships possible on an unprecedented scale in the middle of the century, leading to wars that were also unprecedented. However, the increased communications contributed to democratization.

Technological developments included the development of airplanes and space exploration, nuclear technology, advancement in genetics, and the dawning of the Information Age.

Major political developments included the Israeli–Palestinian conflict, two world wars, and the Cold War. It also saw the former British Empire lose most of its remaining political power over commonwealth countries, most notably by ways of the dividing of the British crown into several sovereignties by the Statute of Westminster, the patriation of constitutions by the Canada Act 1982 and the Australia Act 1986, and by the independence of countries like India, Pakistan, South Africa, and Ireland.

The First World War was a world conflict, raging from July 1914 to the final Armistice on 11 November 1918. The Allied Powers, led by the British Empire, France, Russia until March 1918, Japan and the United States after 1917, defeated the Central Powers, led by the German Empire, Austro-Hungarian Empire and the Ottoman Empire. The war caused the disintegration of four empires — the Austro-Hungarian, German, Ottoman, and Russian ones — as well as radical change in the European and Middle Eastern maps. The Allied powers before 1917 are sometimes referred to as the Triple Entente, and the Central Powers are sometimes referred to as the Triple Alliance.

Much of the fighting in World War I took place along the Western Front, within a system of opposing manned trenches and fortifications (separated by a "no man's land") running from the North Sea to the border of Switzerland. On the Eastern Front, the vast eastern plains and limited rail network prevented a trench warfare stalemate from developing, although the scale of the conflict was just as large. Hostilities also occurred on and under the sea and — for the first time — from the air. More than 9 million soldiers died on the various battlefields, and nearly that many more in the participating countries' home fronts on account of food shortages and genocide committed under the cover of various civil wars and internal conflicts. Notably, more people died of the worldwide influenza outbreak at the end of the war and shortly after than died in the hostilities. The unsanitary conditions engendered by the war, severe overcrowding in barracks, wartime propaganda interfering with public health warnings, and migration of so many soldiers around the world helped the outbreak become a pandemic.[10]

Ultimately, World War I created a decisive break with the old world order that had emerged after the Napoleonic Wars, which was modified by the mid-19th century's nationalistic revolutions. The results of World War I would be important factors in the development of World War II approximately 20 years later.

The Interwar period was the period between the end of World War I in 1918 and the beginning of World War II in 1939. It included the Roaring Twenties, the Great Depression, and the rise of communism in Russia and fascism in Italy and Germany.

World War II was a global military conflict that took place in 1939–1945. It was the largest and deadliest war in history, culminating in the Holocaust and ending with the dropping of the atom bomb.

Even though Japan had been fighting in China since 1937, the conventional view is that the war began on September 1, 1939, when Nazi Germany invaded Poland. Within two days the United Kingdom and France declared war on Germany, even though the fighting was confined to Poland. Pursuant to a then-secret provision of its non-aggression Molotov–Ribbentrop Pact, the Soviet Union joined with Germany on September 17, 1939, to conquer Poland and to divide Eastern Europe.

The Allies were initially made up of Poland, the United Kingdom, France, Australia, Canada, New Zealand, South Africa, as well as British Commonwealth countries which were controlled directly by the UK, such as the Indian Empire. All of these countries declared war on Germany in September 1939.

Following the lull in fighting, known as the "Phoney War", Germany invaded western Europe in May 1940. Six weeks later, France, in the mean time attacked by Italy as well, surrendered to Germany, which then tried unsuccessfully to conquer Britain. On September 27, Germany, Italy, and Japan signed a mutual defense agreement, the Tripartite Pact, and were known as the Axis Powers.

Nine months later, on June 22, 1941, Germany launched a massive invasion of the Soviet Union, which promptly joined the Allies. Germany was now engaged in fighting a war on two fronts. This proved to be a mistake by Germany; many historians believe that if Germany had successfully carried out the invasion of Britain and put forth their best effort, the war may have turned in favor of the Axis.

On December 7, 1941, Japan attacked the United States at Pearl Harbor, bringing it too into the war on the Allied side. China also joined the Allies, as eventually did most of the rest of the world. China was in turmoil at the time, and attacked Japanese armies through guerilla-type warfare. By the beginning of 1942, the major combatants were aligned as follows: the British Commonwealth, the United States, and the Soviet Union were fighting Germany and Italy; and the British Commonwealth, China, and the United States were fighting Japan. From then through August 1945, battles raged across all of Europe, in the North Atlantic Ocean, across North Africa, throughout Southeast Asia, throughout China, across the Pacific Ocean and in the air over Japan.

Italy surrendered in September 1943 and split in a northern Germany-occupied puppet state and in an Allies-friendly state in the South; Germany surrendered in May 1945. Following the atomic bombings of Hiroshima and Nagasaki, Japan surrendered, marking the end of the war on September 2, 1945.

It is possible that around 62 million people died in the war; estimates vary greatly. About 60% of all casualties were civilians, who died as a result of disease, starvation, genocide (in particular, the Holocaust), and aerial bombing. The former Soviet Union and China suffered the most casualties. Estimates place deaths in the Soviet Union at around 23 million, while China suffered about 10 million. No country lost a greater portion of its population than Poland: approximately 5.6 million, or 16%, of its pre-war population of 34.8 million died.

The Holocaust (which roughly means "burnt whole") was the deliberate and systematic murder of millions of Jews and other "unwanted" during World War II by the Nazi regime in Germany. Several differing views exist regarding whether it was intended to occur from the war's beginning, or if the plans for it came about later. Regardless, persecution of Jews extended well before the war even started, such as in the Kristallnacht (Night of Broken Glass). The Nazis used propaganda to great effect to stir up anti-Semitic feelings within ordinary Germans.

After World War II, Europe was informally split into Western and Soviet spheres of influence. Western Europe later aligned as North Atlantic Treaty Organization (NATO) and Eastern Europe as the Warsaw Pact. There was a shift in power from Western Europe and the British Empire to the two new superpowers, the United States and the Soviet Union. These two rivals would later face off in the Cold War. In Asia, the defeat of Japan led to its democratization. China's civil war continued through and after the war, resulting eventually in the establishment of the People's Republic of China. The former colonies of the European powers began their road to independence.

The Cold War between the "West" (the United States, Western Europe, and Japan) and the "East" (the Soviet Union, Eastern Europe, and China) dominated politics from the end of World War II in 1945 until the collapse of the Soviet Union in 1991, at which point the Cold War ended and the post–Cold War era began (which includes most of the 1990s, the last decade of the 20th century).

The Korean War, Vietnam War, and later the Soviet–Afghan War, dominated the political life, while the counterculture of the 1960s and the rise of computers changed society in very different, complex ways, including higher social and local mobility.

At the end of the twentieth century, the world was at a major crossroads. Throughout the century, more technological advances had been made than in all of preceding history. Computers, the Internet, and other technology radically altered daily lives. However, several problems faced the world during the Cold War period and the 1990s that followed.

First of all, the gap between rich and poor nations continued to widen. Some said that this problem could not be fixed, that there were a set amount of wealth and it could only be shared by so many. Others said that the powerful nations with large economies were not doing enough to help improve the rapidly evolving economies of the Third World. However, developing countries faced many challenges, including the scale of the task to be surmounted, rapidly growing populations, and the need to protect the environment, and the cost that goes along with it.

Secondly, disease threatened to destabilize many regions of the world. Viruses such as West Nile and Avian influenza continued to spread quickly and easily. In poor nations, malaria and other diseases affected the majority of the population. Millions were infected with HIV, the virus which causes AIDS, which was becoming an epidemic in southern Africa and around the world.

Increased globalization, specifically Americanization, was also occurring. While not necessarily a threat, it was causing anti-Western and anti-American feelings in parts of the world, especially the Middle East. English was quickly becoming the global language, with people who did not speak it becoming increasingly disadvantaged.

Terrorism, dictatorship, and the spread of nuclear weapons were also issues requiring immediate attention. Dictators such as Kim Jong-il in North Korea continued to lead their nations toward the development of nuclear weapons. The fear existed that not only are terrorists already attempting to get nuclear weapons, but that they have already obtained them.

The 2000s decade refers to the years from 2000 to 2009 inclusively. The 2000s were marked generally with an escalation of the social issues of the 1990s, which included the rise of terrorism, stress, the rapid, exponential expansion of economic globalization on an unprecedented scale, the rapid expansion of communications and telecommunications with mobile phones and the Internet and international pop culture.

In North America and the Middle East, most major political developments in the 2000s revolved around the War on Terrorism and the Iraq War. Elsewhere, the major theme was the rapid development of Asia's economic and political potential, with China, experiencing immense economic growth, moving toward the status of a regional power and billion-consumer market. India, along with many other developing countries, were also growing rapidly, and began integrating themselves into the world economy.

A trend connecting economic and political events in North America, Asia, and the Middle East was the rapidly increasing demand for fossil fuels, which, along with fewer new petroleum finds, greater extraction costs (see peak oil), and political turmoil, saw the price of gas and oil soar ~500% between 2000 and 2005. In some places, especially in Europe, gas could be $5 a gallon, depending on the currency.

The entire written works of humanity, from the beginning of recorded history to 2003, in all known languages, are estimated to be at five exabytes of data.[11][12] Since 2003, with the beginning of social media and "user-generated content", the same amount of data is created every two days.[13] The growth of human knowledge and information continues at an exponential rate.

Telecommunications in the early 21st century are much more advanced and universal than they were in the late 20th century. Only a few percent of the world's population were Internet users and cellular phone owners in the late 1990s; as of 2023, 64.4% of the world's population is online, and as of 2019, an estimated 67% own a cell phone.[14] In the 2010s, artificial intelligence, mainly in the form of deep learning and machine learning, became more prevalent and is prominently used in Gmail and Google's search engine, in banking, with the military and other areas. In 2020, 9% of the world's population still lacked access to electricity.[15]

India's Prayag Kumbh Mela is regarded as the world's largest religious festival.

In 2001, Dennis Tito became the first space tourist, beginning the era of commercial spaceflight. Entrepreneurs Elon Musk and Richard Branson are working towards commercial space exploration, colonization and tourism, while China and India have made substantial strides in their space programs. On 3 January 2019, China landed a robotic spacecraft on the far side of the Moon, the first to do so.[16]

Major events relating to the War on Terrorism included the September 11, 2001 Attacks, the Moscow theater hostage crisis, the 2003 Istanbul bombings, the 2004 Madrid train bombings, the Beslan school siege, the 2005 London bombings, the 2005 Delhi bombings, and the 2008 Mumbai Hotel Siege.

The violence in Iraq, even after democratic elections on January 30, 2005, caused much political stir in all countries occupying the country (United States, Britain, Australia, etc), and political debates of these countries in 2006 and 2007 were highly influenced by the unstable situation in the Near East, especially Iraq and the discussion over Iran's nuclear weapons program.

Less influential, but omnipresent, was the debate on Turkey's participation in the European Union.

New virus strains, such as SARS and swine flu, emerged and spread during the 2000s.

The 2010s featured several major events in the Middle East which had effects elsewhere in the world. These events included the Arab Spring, the Syrian civil war, and the expansion of the extremist terrorist group ISIL. Beginning in 2015, Europe was affected by a migrant crisis. Several terrorist attacks occurred in Europe during the 2010s, including the November 2015 Paris attacks.

In 2016, nationalist political movements led to the Brexit referendum in the United Kingdom and the election of Donald Trump as the President of the United States.

The 2020s have so far been dominated by a global pandemic and the first major war in Europe since World War II.

In 2022, Russia invaded Ukraine, a major escalation of a conflict that has lasted since 2014.

In 2020, an outbreak of the COVID-19 disease, first documented in late 2019 in Wuhan, China, spread to other countries becoming a global pandemic, which caused a major socio-economic disruption all over the world. Many countries ordered mandatory lockdowns on movement and closures of non-essential businesses.[27] The threat of the disease caused the COVID-19 recession, although the distribution of vaccines has since eased the economic impact in many countries.

More generally, COVID-19 has been held up as an example of a global catastrophic risk unique to the modern era's ease of travel. New diseases can spread far faster and further in the contemporary era than any previous era of human history; pandemic prevention is one resulting field to ensure that if this happens with a sufficiently deadly virus, humanity can take measures to stop its spread.

The 2020s began with the COVID-19 pandemic—the first reports of the virus were published on December 31, 2019, though the first cases are said to have appeared nearly a month earlier[28]—which caused a global economic recession as well as continuing financial inflation concerns and a global supply chain crisis.

On 15 November 2022, the world population grew to over 8 billion people, and in 2023, India overtook China as the most populous country in the world.[29][30]
