The War of the Spanish Succession was a European great power conflict fought between 1701 and 1714. The death of Charles II of Spain in November 1700 without children led to a contest for the succession between two candidates. These were Philip of Anjou, backed by his grandfather Louis XIV of France, and Archduke Charles of Austria, supported by the Grand Alliance. Significant related conflicts include the Great Northern War (1700–1721) and Queen Anne's War (1702–1713).

The Northwest Indian War was an armed conflict for control of the Northwest Territory between the United States and a loose confederation of Native American peoples who called themselves the United Indian Nations but are better known today as the Northwestern Confederacy. The United States Army considers the conflict to be the first of the American Indian Wars.

Charles Robert Darwin was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental scientific concept. In a joint presentation with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by burial in Westminster Abbey.

Major areas of conflict included Europe and the Middle East, as well as parts of Africa and the Asia-Pacific. The war saw important developments in weaponry including tanks, aircraft, artillery, machine guns, and chemical weapons. One of the deadliest conflicts in history, it resulted in an estimated 15 to 22 million military and civilian casualties and genocide. The movement of large numbers of people was a major factor in the deadly Spanish flu pandemic.

The National Football League (NFL) is a professional American football league in the United States. Composed of 32 teams, it is divided equally between the American Football Conference (AFC) and the National Football Conference (NFC). The NFL is one of the major professional sports leagues in the United States and Canada and the highest professional level of American football in the world. Each NFL season begins annually with a three-week preseason in August, followed by an 18-week regular season, which runs from early September to early January, with each team playing 17 games and having one bye week. Seven teams from each conference, including the four division winners and three wild card teams, then advance to the playoffs, a single-elimination tournament, which culminates in the Super Bowl, played in early February between the winners of the AFC and NFC championship games. The NFL is headquartered in New York City.

World War II, or the Second World War, was a global conflict between two coalitions: the Allies and the Axis powers. Nearly all of the world's countries participated. Tanks and aircraft played major roles, the latter enabling the strategic bombing of cities and delivery of the only nuclear weapons used in war. World War II was the deadliest conflict in history, causing the death of 60 to 75 million people. Millions died as a result of massacres, starvation, disease, and genocides, including the Holocaust. After the Allied victory, Germany, Austria, Japan, and Korea were occupied, and German and Japanese leaders were tried for war crimes.

New York City is known for its fast pace and continuous urban energy.

The Battle of Philippeville, also known as the Philippeville massacre or the August Offensive, was a series of raids launched on 20 August 1955 on various cities and towns of the Constantine region by FLN insurgents and armed mobs during the Algerian War between France and the Algerian rebels. The raids, which mostly took the form of ethnic riots, resulted in the massacre of several dozens of European settlers, known as pieds-Noirs. The massacres were then followed by reprisals by the French army and pied-noir vigilantes, which resulted in the death of several thousand Muslim Algerians. The events of late August 1955 in the Constantinois region are considered to be a major turning point of the Algerian War.

NS Savannah was the first nuclear-powered merchant ship, launched on July 21, 1959, two years after the Soviet ice-breaker Lenin, the first nuclear-powered civilian vessel. A demonstration project for the potential peacetime uses of nuclear energy, she was built in the late 1950s at a cost of $46.9 million. Savannah was given the new designation "NS" for "Nuclear Ship", replacing the traditional commercial vessel prefix "SS" for "Screw Steamer", and was named after SS Savannah, the first steamship to cross the Atlantic Ocean. She was funded by United States government agencies as part of President Dwight D. Eisenhower's 1955 "Atoms for Peace" program, and was in service between 1962 and 1972 as one of only four nuclear-powered cargo ships ever built.

The Viking program consisted of a pair of identical American space probes, Viking 1 and Viking 2 both launched in 1975, and landed on Mars in 1976. The mission effort began in 1968 and was managed by the NASA Langley Research Center. Each spacecraft was composed of two main parts: an orbiter spacecraft which photographed the surface of Mars from orbit, and a lander which studied the planet from the surface. The orbiters also served as communication relays for the landers once they touched down.

The Voyager program is an American scientific program that employs two interstellar probes, Voyager 1 and Voyager 2. They were launched in 1977 to take advantage of a favorable planetary alignment to explore the two gas giants Jupiter and Saturn and potentially also the ice giants, Uranus and Neptune—to fly near them while collecting data for transmission back to Earth. After Voyager 1 successfully completed its flyby of Saturn and its moon Titan, it was decided that Voyager 2 would continue on its pre-planned trajectory to fly by Uranus and Neptune.

The Yellowstone fires of 1988 collectively formed the largest wildfire in the recorded history of Yellowstone National Park in the United States. Starting as many smaller individual fires, the flames quickly spread out of control due to drought conditions and increasing winds, combining into several large conflagrations which burned for several months. The fires almost destroyed two major visitor destinations and, on September 8, 1988, the entire park was closed to all non-emergency personnel for the first time in its history. Only the arrival of cool and moist weather in the late autumn brought the fires to an end. A total of 793,880 acres (3,213 km2), or 36 percent of the national park, burned at varying levels of severity.

The Troubles were an ethno-nationalist conflict in Northern Ireland that lasted for about 30 years from the late 1960s to 1998. Also known internationally as the Northern Ireland conflict, it began in the late 1960s and is usually deemed to have ended with the Good Friday Agreement of 1998. Although the Troubles mostly took place in Northern Ireland, at times violence spilled over into parts of the Republic of Ireland, England, and mainland Europe.

There are 1.76 million Meitei native speakers in India according to the 2011 census, 1.52 million of whom are found in the state of Manipur, where they represent the majority of its population. There are smaller communities in neighbouring Indian states, such as Assam (168,000), Tripura (24,000), Nagaland (9,500), and elsewhere in the country (37,500). The language is also spoken by smaller groups in neighbouring Myanmar and Bangladesh.

The largest of the Souhane massacres occurred in the small mountain town of Souhane on 20–21 August 1997. 64 people were killed, and 15 women were kidnapped; the resulting terror triggered a mass exodus, reducing the town's population down from 4000 before the massacre to just 103 in 2002. Smaller-scale massacres later took place on November 27, 1997 and 2 March 2000, when some 10 people from a single household were killed by guerrillas. The massacres were attributed on Islamist groups such as the GIA.
