The American Civil War was a civil war in the United States fought between states supporting the federal union and southern states that voted to secede and form the Confederate States of America. The central cause of the war was the status of slavery, especially the expansion of slavery into newly acquired land after the Mexican–American War. On the eve of the Civil War in 1860, four million of the 32 million Americans were black slaves, mostly in the South.

In the history of Europe, the Middle Ages or medieval period lasted approximately from the 5th to the late 15th centuries. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages.
Nazi Germany, officially known as the German Reich from 1933 until 1943, and the Greater German Reich from 1943 to 1945, was the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country which they transformed into a dictatorship. Under Hitler's rule, Germany quickly became a totalitarian state where nearly all aspects of life were controlled by the government. The Third Reich, meaning "Third Realm" or "Third Empire", alluded to the Nazis' conceit that Nazi Germany was the successor to the earlier Holy Roman Empire (800–1806) and German Empire (1871–1918). The Third Reich, which Hitler and the Nazis referred to as the Thousand Year Reich, ended in May 1945 after just 12 years, when the Allies defeated Germany, ending World War II in Europe.
The Summer Olympic Games, also known as the Games of the Olympiad, are a major international multi-sport event normally held once every four years. The Games were first held in 1896 in Athens, Greece, and were most recently the 2020 Summer Olympics held in 2021 in Tokyo, Japan. The International Olympic Committee (IOC) organises the Games and oversees the host city's preparations. In each Olympic event, gold medals are awarded for first place, silver medals are awarded for second place, and bronze medals are awarded for third place; this tradition began in 1904. The Winter Olympic Games were created out of the success of the Summer Olympics.
The Vietnam War, also known as the Second Indochina War, was a conflict in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and South Vietnam. North Vietnam was supported by the Soviet Union, China, and other communist allies; South Vietnam was supported by the United States, South Korea, the Philippines, Australia, Thailand, and other anti-communist allies. The war, considered a Cold War-era proxy war by some, lasted almost 20 years, with direct U.S. involvement ending in 1973, and included the Laotian Civil War and the Cambodian Civil War, which ended with all three countries becoming communist in 1975.
Yugoslavia was a country in Southeast Europe and Central Europe for most of the 20th century. It came into existence after World War I in 1918 under the name of the Kingdom of Serbs, Croats and Slovenes by the merger of the provisional State of Slovenes, Croats and Serbs with the Kingdom of Serbia, and constituted the first union of the South Slavic people as a sovereign state, following centuries in which the region had been part of the Ottoman Empire and Austria-Hungary. Peter I of Serbia was its first sovereign. The kingdom gained international recognition on 13 July 1922 at the Conference of Ambassadors in Paris. The official name of the state was changed to Kingdom of Yugoslavia on 3 October 1929.

The attack on Pearl Harbor was a surprise military strike by the Imperial Japanese Navy Air Service upon the United States against the naval base at Pearl Harbor in Honolulu, Territory of Hawaii, just before 08:00, on Sunday morning, December 7, 1941. The attack led to the United States' formal entry into World War II the next day. The Japanese military leadership referred to the attack as the Hawaii Operation and Operation AI, and as Operation Z during its planning. Japan intended the attack as a preventive action to keep the United States Pacific Fleet from interfering with its planned military actions in Southeast Asia against overseas territories of the United Kingdom, the Netherlands, and the United States. Over the course of seven hours there were coordinated Japanese attacks on the U.S.-held Philippines, Guam, and Wake Island and on the British Empire in Malaya, Singapore, and Hong Kong.
The Soviet–Afghan War was a conflict wherein insurgent groups, as well as smaller Shi'ite and Maoist groups, fought a nine-year guerrilla war against the Democratic Republic of Afghanistan and the Soviet Army throughout the 1980s, mostly in the Afghan countryside. The Mujahideen were variously backed primarily by the United States, Pakistan, Iran, Saudi Arabia, China, and the United Kingdom; the conflict was a Cold War-era proxy war. Between 562,000 and 2,000,000 Afghans were killed and millions more fled the country as refugees, mostly to Pakistan and Iran. Between 6.5%–11.5% of Afghanistan's population is estimated to have perished in the conflict. The war caused grave destruction in Afghanistan and is believed to have contributed to the Soviet collapse and the end of the Cold War, in hindsight leaving a mixed legacy to people in both territories.
Millennials, also known as Generation Y or Gen Y, are the demographic cohort following Generation X and preceding Generation Z. Researchers and popular media use the early 1980s as starting birth years and the mid-1990s to early 2000s as ending birth years, with the generation typically being defined as people born from 1981 to 1996. Most Millennials are the children of baby boomers and early Gen Xers; Millennials are often the parents of Generation Alpha.

Apartheid was a system of institutionalised racial segregation that existed in South Africa and South West Africa from 1948 until the early 1990s. Apartheid was characterized by an authoritarian political culture based on baasskap, which ensured that South Africa was dominated politically, socially, and economically by the nation's minority white population. According to this system of social stratification, white citizens had the highest status, followed by Asians and Coloureds, then black Africans. The economic legacy and social effects of apartheid continue to the present day.
The British Raj was the rule by the British Crown on the Indian subcontinent from 1858 to 1947. The rule is also called Crown rule in India, or direct rule in India.

The region was sometimes called the Indian Empire, though not officially.
The Holocaust, also known as the Shoah, was the genocide of European Jews during World War II. Between 1941 and 1945, Nazi Germany and its collaborators systematically murdered some six million Jews across German-occupied Europe, around two-thirds of Europe's Jewish population. The murders were carried out in pogroms and mass shootings; by a policy of extermination through labor in concentration camps; and in gas chambers and gas vans in German extermination camps, chiefly Auschwitz-Birkenau, Bełżec, Chełmno, Majdanek, Sobibór, and Treblinka in occupied Poland.

RMS Titanic was a British passenger liner operated by the White Star Line that sank in the North Atlantic Ocean on 15 April 1912, after striking an iceberg during her maiden voyage from Southampton to New York City. Of the estimated 2,224 passengers and crew aboard, more than 1,500 died, making the sinking at the time one of the deadliest of a single ship and the deadliest peacetime sinking of a superliner or cruise ship to date. With much public attention in the aftermath, the disaster has since been the material of many artistic works and a founding material of the disaster film genre.
The Russian Empire was a historical empire that extended across Eurasia and North America from 1721, following the end of the Great Northern War, until the Republic was proclaimed by the Provisional Government that took power after the February Revolution of 1917. The third-largest empire in history, at one point stretching over three continents, Europe, Asia, and North America, the Russian Empire was surpassed in size only by the British and Mongol empires. The rise of the Russian Empire coincided with the decline of neighboring rival powers: the Swedish Empire, the Polish–Lithuanian Commonwealth, Persia, the Ottoman Empire, and Qing China. It played a major role in 1812–1814 in defeating Napoleon's ambitions to control Europe and expanded to the west and south, becoming one of the most powerful European empires of the time.
