Elizabeth II (21 April 1926 – 8 September 2022), became head of the Commonwealth and queen regnant of seven independent Commonwealth countries: the United Kingdom, Canada, Australia, New Zealand, South Africa, Pakistan, and Ceylon on 6 Feb 1952.

She reigned through major constitutional changes, such as devolution in the UK, Canadian patriation, and the decolonisation of Africa. Her many historic visits and meetings include a state visit to the Republic of Ireland and visits to or from five popes. Significant events have included her coronation in 1953 and the celebrations of her Silver, Golden, and Diamond Jubilees in 1977, 2002, and 2012 respectively. In 2017, she became the first British monarch to reach a Sapphire Jubilee. She is the longest-lived and longest-reigning British monarch as well as the world's longest-reigning queen regnant and female head of state, the oldest and longest-reigning monarch and the longest-serving head of state.

The Vietnam War took place from 1 November 1955 to the fall of Saigon on 30 April 1975, with US involvement ending in 1973. It was the second of the Indochina Wars and was officially fought between North Vietnam and the government of South Vietnam. The North Vietnamese army was supported by the Soviet Union, China, and other communist allies; the South Vietnamese army was supported by the United States, South Korea, the Philippines, Australia, Thailand and other anti-communist allies.

An anti-war movement gained strength in the US. Nixon appealed to the "silent majority" of Americans who he said supported the war but revelations of the My Lai Massacre, and the 1969 "Green Beret Affair" provoked national and international outrage. In 1971 the Pentagon Papers were leaked to The New York Times. The top-secret history of US involvement in Vietnam, commissioned by the Department of Defense, detailed a long series of public deceptions on the part of the US government.

The Beatles were an English rock band formed in Liverpool in 1960. With members John Lennon, Paul McCartney, George Harrison and Ringo Starr, they became widely regarded as the foremost and most influential music band in history, integral to pop music's evolution into an art form and to the development of the counterculture of the 1960s. Rooted in skiffle, beat and 1950s rock and roll, the group later experimented with several musical styles, ranging from pop ballads and Indian music to psychedelia and hard rock, often incorporating classical elements and unconventional recording techniques in innovative ways.

The Beatles are the best-selling band in history, with estimated sales of over 800 million records worldwide. They are the best-selling music artists in the United States, with 178 million certified units. The group was inducted into the Rock and Roll Hall of Fame in 1988, and all four main members were inducted individually from 1994 to 2015. They have also had more number-one albums on the British charts and sold more singles in the UK than any other act. They were also collectively included in Time magazine's compilation of the twentieth century's 100 most influential people.

Lester Bowles "Mike" Pearson> (23 April 1897 – 27 December 1972) was a Canadian scholar, statesman, soldier, prime minister, and diplomat, who won the Nobel Peace Prize in 1957 for organizing the United Nations Emergency Force to resolve the Suez Canal Crisis. He was the 14th prime minister of Canada from 22 April 1963 to 20 April 1968, as the head of two back-to-back Liberal minority governments following elections in 1963 and 1965.

During Pearson's time as Prime Minister, his Liberal minority governments introduced universal health care, student loans, the Canada Pension Plan, the Order of Canada, and the Maple Leaf flag. His Liberal government also unified Canada's armed forces. Pearson convened the Royal Commission on Bilingualism and Biculturalism, and he kept Canada out of the Vietnam War. In 1967, his government passed Bill C-168, which de facto abolished capital punishment in Canada by restricting it to a few capital offences for which it was never used, and which themselves were abolished in 1976. With these accomplishments, together with his groundbreaking work at the United Nations and in international diplomacy, Pearson is generally considered among the most influential Canadians of the 20th century and is ranked among the greatest Canadian Prime Ministers.

Lyndon Baines Johnson (August 27, 1908 – January 22, 1973), often referred to by his initials LBJ, was an American politician who served as the 36th president of the United States from 1963 to 1969.

On November 22, 1963, Kennedy was assassinated and Johnson succeeded him as president. The following year, Johnson won a landslide in 1964, defeating Senator Barry Goldwater of Arizona. With 61.1 percent of the popular vote, Johnson won the largest share of the popular vote of any candidate since the largely uncontested 1820 election.

James Harold Wilson, Baron Wilson of Rievaulx, (11 March 1916 – 24 May 1995) was a British Labour politician who served as Prime Minister of the United Kingdom from 1964 to 1970 and 1974 to 1976.

Wilson's first period as Prime Minister coincided with a period of low unemployment and relative economic prosperity, though hindered by significant problems with Britain's external balance of payments. In 1969 he sent British troops to Northern Ireland. After losing the 1970 election to Edward Heath, he spent four years as Leader of the Opposition before the February 1974 election resulted in a hung parliament. After Heath's talks with the Liberals broke down, Wilson returned to power as leader of a minority government until another general election in October, resulting in a narrow Labour victory.
