George VI was king of the United Kingdom and the Dominions of the British Commonwealth from 11 December 1936 until his death in 1952. He was the last emperor of India and the first head of the Commonwealth.

As the second son of King George V, George VI was not expected to inherit the throne and spent his early life in the shadow of his elder brother, Edward who ascended the throne upon the death of their father in 1936. However, later that year Edward abdicated to marry divorcee Wallis Simpson, and George ascended the throne as the third monarch of the House of Windsor.

Harry S. Truman (May 8, 1884 – December 26, 1972) was the 33rd president of the United States (1945–1953), succeeding upon the death of Franklin D. Roosevelt after serving as vice president. He implemented the Marshall Plan to rebuild the economy of Western Europe, and established the Truman Doctrine and NATO.

Soon after succeeding to the presidency he became the only world leader to have used nuclear weapons in war. Truman's administration engaged in an internationalist foreign policy and renounced isolationism. He rallied his New Deal coalition during the 1948 presidential election and won a surprise victory that secured his own presidential term.

Clement Richard Attlee, 1st Earl Attlee, (3 January 1883 – 8 October 1967) was a British statesman and Labour Party politician who served as Prime Minister of the United Kingdom from 1945 to 1951.

Following the end of the War in Europe, Attlee and Churchill favoured the coalition government remaining in place until Japan had been defeated. However, Herbert Morrison made it clear that the Labour Party would not be willing to accept this, and Churchill was forced to call an immediate election. Labour won by a huge landslide, winning 393 seats in the House of Commons, a working majority of 146. This was the first time in history that the Labour Party had won a majority in Parliament.

The Korean War was a product of the Cold War and began when North Korean forces - supported by the Soviet Union and China -moved into the south on 25 June 1950. The UN authorized the dispatch of forces to repel the North Korean invasion. 21 UN countries contributed to the UN force, with the US providing around 90% of the military personnel. The fighting ended on 27 July 1953, when an armistice was signed. The agreement created the Korean Demilitarized Zone to separate North and South Korea, and allowed the return of prisoners. However, no peace treaty was ever signed, and according to some sources the two Koreas are technically still at war. In April 2018, the leaders of North and South Korea met at the DMZ and agreed to work towards a treaty to formally end the war

Sir Winston Leonard Spencer-Churchill (30 November 1874 – 24 January 1965) was a British politician, statesman, army officer, and writer, who was Prime Minister of the United Kingdom from 1940 to 1945 and again from 1951 to 1955. As Prime Minister, Churchill led Britain to victory in the Second World War. Ideologically an economic liberal and British imperialist, he began and ended his parliamentary career as a member of the Conservative Party, which he led from 1940 to 1955, but for twenty years from 1904 he was a prominent member of the Liberal Party.

Widely considered one of the 20th century's most significant figures, Churchill remains popular in the UK and Western world, where he is seen as a victorious wartime leader who played an important role in defending liberal democracy from the spread of fascism. Also praised as a social reformer and writer, among his many awards was the Nobel Prize in Literature.

Elizabeth II 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 has 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 current monarch and the longest-serving current head of state.

Francis Crick and James Watson, analyse data taken by Rosalind Franklin and Maurice Wilkins, to decipher the double helical structure of DNA.

The Nobel Prize in Physiology or Medicine 1962 was awarded jointly to Crick, Watson & Wilkins. Having died in 1958, and there being no posthumous awards, Franklin did not receive an award.

Dwight David "Ike" Eisenhower (October 14, 1890 – March 28, 1969) was an American army general and statesman who served as the 34th president of the United States from 1953 to 1961.

During World War II, he was a five-star general in the United States Army and served as supreme commander of the Allied Expeditionary Forces in Europe. He was responsible for planning and supervising the invasion of North Africa in Operation Torch in 1942–43 and the successful invasion of France and Germany in 1944–45 from the Western Front. In 1952, Eisenhower entered the presidential race as a Republican to block the isolationist foreign policies of Senator Robert A. Taft, who opposed NATO and wanted no foreign entanglements. He won that election and the 1956 election in landslides.

The Breaking of the 4 Minute Mile, by Roger Bannister, took place in Oxford, watched by about 3,000 spectators. With winds of up to 25 mph before the event, Bannister had said that he would try again at another meet. But the winds dropped just before the race and Bannister did run.

The race was broadcast live by BBC Radio and commentated by 1924 Olympic 100 metres champion Harold Abrahams, of Chariots of Fire fame.

Robert Anthony Eden, 1st Earl of Avon, (12 June 1897 – 14 January 1977) was a British Conservative politician who served a relatively brief term as Prime Minister of the United Kingdom from 1955 to 1957. Having been deputy to Winston Churchill for almost 15 years, he succeeded him as the Leader of the Conservative Party and Prime Minister in April 1955, and a month later won a general election.

Eden's worldwide reputation as an opponent of appeasement, a "man of peace", and a skilled diplomat was overshadowed in 1956 when the United States refused to support the Anglo-French military response to the Suez Crisis. Two months after ordering an end to the Suez operation, he resigned as Prime Minister on grounds of ill health and because he was widely suspected of having misled the House of Commons over the degree of collusion with France and Israel.

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.

Maurice Harold Macmillan, 1st Earl of Stockton, (10 February 1894 – 29 December 1986) was a British statesman and Conservative Party politician who served as Prime Minister from 1957 to 1963. Nicknamed "Supermac", he was known for his pragmatism, wit and unflappability.

He presided over an age of affluence, marked by low unemployment and high - if uneven - growth. He told the nation they had 'never had it so good', but warned of the dangers of inflation, summing up the fragile prosperity of the 1950s. Macmillan rebuilt the Special Relationship with the United States from the wreckage of the Suez Crisis, and redrew the world map by decolonising sub-Saharan Africa. Reconfiguring the nation's defences to meet the realities of the nuclear age, he ended National Service, strengthened the nuclear forces by acquiring Polaris, and pioneered the Nuclear Test Ban with the United States and the Soviet Union. His unwillingness to disclose United States nuclear secrets to France contributed to a French veto of the United Kingdom's entry into the European Economic Community.

Sputnik 1 was the first artificial Earth satellite. The Soviet Union launched it into an elliptical low Earth orbit on 4 October 1957, orbiting for three weeks before its batteries died, then silently for two more months before falling back into the atmosphere.

It was a 58 cm (23 in) diameter polished metal sphere, with four external radio antennas to broadcast radio pulses. Its radio signal was easily detectable even by radio amateurs, and the 65° inclination and duration of its orbit made its flight path cover virtually the entire inhabited Earth. This surprise success precipitated the American Sputnik crisis and triggered the Space Race, a part of the Cold War. The launch ushered in new political, military, technological, and scientific developments.

John Fitzgerald "Jack" Kennedy (May 29, 1917 – November 22, 1963), commonly referred to by his initials JFK, was an American politician who served as the 35th president of the United States from January 1961 until his assassination in November 1963.

He served at the height of the Cold War, and the majority of his presidency dealt with managing relations with the Soviet Union. A member of the Democratic Party, Kennedy represented Massachusetts in the U.S. House of Representatives and Senate prior to becoming president. On November 22, 1963, Kennedy was assassinated in Dallas, Texas. Pursuant to the Presidential Succession Act, Vice President Lyndon B. Johnson was sworn in as president later that day

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.

Alexander Frederick Douglas-Home (pronounced "Hyume"), Baron Home of the Hirsel, (2 July 1903 – 9 October 1995) was a British statesman and Conservative Party politician who served as Prime Minister from October 1963 to October 1964.

A plot to kidnap Douglas-Home in April 1964 was foiled by the Prime Minister himself. Two left-wing students from the University of Aberdeen followed him to the house of John and Priscilla Buchan, where he was staying. He was alone at the time and answered the door, where the students told him that they planned to kidnap him. He responded, "I suppose you realise if you do, the Conservatives will win the election by 200 or 300." He gave his intending abductors some beer, and they abandoned their plot.

John Fitzgerald Kennedy, 35th US President, was assassinated on Friday, November 22, 1963, at 12:30 pm in Dallas, Texas, while riding in a presidential motorcade through. Kennedy was riding with his wife Jacqueline, Texas Governor John Connally, and Connally's wife Nellie when he was fatally shot by former US Marine Lee Harvey Oswald firing from a nearby building. Governor Connally was seriously wounded in the attack. The motorcade rushed to Parkland Memorial Hospital where President Kennedy was pronounced dead about thirty minutes after the shooting.

Oswald was arrested and charged under Texas state law with the murder of Kennedy as well as that of Dallas policeman J. D. Tippit, who had been fatally shot a short time after the assassination. At 11:21 am on Sunday, November 24, 1963, as live television cameras covered his transfer to the Dallas County Jail, Oswald was fatally shot in the basement of Dallas Police Headquarters by Dallas nightclub operator Jack Ruby. Oswald was taken to Parkland Memorial Hospital where he soon died. Ruby was convicted of Oswald's murder, though it was later overturned on appeal.

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.

Richard Milhous Nixon (January 9, 1913 – April 22, 1994) was the 37th president of the United States from 1969 until 1974 and the only president to resign from the position.

Nixon ended American involvement in the war in Vietnam in 1973 and brought the American POWs home, and ended the military draft. Nixon's visit to China in 1972 eventually led to diplomatic relations between the two nations and he initiated détente and the Anti-Ballistic Missile Treaty with the Soviet Union the same year.

By late 1973, the Watergate scandal escalated, costing Nixon much of his political support. On August 9, 1974, he resigned in the face of almost certain impeachment and removal from office. After his resignation, he was issued a controversial pardon by his successor, Gerald Ford.

Apollo 11 was the spaceflight that landed the first two people on the Moon. Americans Commander Neil Armstrong and pilot Buzz Aldrin landed the lunar module Eagle at 20:17 UTC. Armstrong was the first person to step onto the lunar surface, at 02:56:15 UTC; Aldrin joined him 20 minutes later. Michael Collins piloted the command module Columbia in lunar orbit while they were on the surface. Armstrong and Aldrin spent 21.5 hours on the lunar surface before rejoining Columbia in lunar orbit.

Armstrong's first step onto the lunar surface was broadcast on live TV to a worldwide audience. He described the event as "one small step for [a] man, one giant leap for mankind." Apollo 11 effectively ended the Space Race and fulfilled a national goal proposed in 1961 by President Kennedy: "before this decade is out, of landing a man on the Moon and returning him safely to the Earth."

Sir Edward Richard George Heath (9 July 1916 – 17 July 2005), known as Ted Heath, was a British politician who served as Prime Minister of the United Kingdom from 1970 to 1974 and Leader of the Conservative Party from 1965 to 1975. He was a strong supporter of the European Community (EC), and after winning the decisive vote in the House of Commons by 336 to 244, he led the negotiations that culminated in Britain's entry into the EC on 1 January 1973. It was, says biographer John Campbell, "Heath's finest hour".

Heath's premiership also coincided with the height of the Troubles in Northern Ireland, with the suspension of the Stormont Parliament and the imposition of direct British rule. Unofficial talks with Provisional Irish Republican Army delegates were unsuccessful, as was the Sunningdale Agreement of 1973.

The Watergate scandal was a major US political scandal during the early 1970s, following a break-in by five men at the Democratic National Committee (DNC) headquarters at the Watergate office complex in Washington, DC on June 17, 1972, and President Richard Nixon's administration's attempt to cover up its involvement. After the five burglars were caught, and the conspiracy was discovered - chiefly through the work of a few journalists, Congressional staffers and an election-finance watchdog official - Watergate was investigated by the US Congress.

The scandal led to the discovery of multiple abuses of power by members of the Nixon administration, the commencement of an impeachment process against the president, and Nixon's resignation.

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.

Berkshire is one of the "home counties" in England. It was recognised by the Queen as the Royal County of Berkshire in 1957 because of the presence of Windsor Castle. In 1974, the towns of Abingdon, Didcot, Faringdon, Wallingford and Wantage and the surrounding villages were transferred to Oxfordshire. This area is Barrett heartlands so you will see many references to these places as part of Berkshire, representing the historical locations.

Gerald Rudolph Ford Jr. (born Leslie Lynch King Jr.; July 14, 1913 – December 26, 2006) was an American politician who served as the 38th president of the United States from August 1974 to January 1977.

After the resignation of Richard Nixon, Ford automatically assumed the presidency. His 895 day-long presidency is the shortest in U.S. history for any president who did not die in office. As president, Ford signed the Helsinki Accords, which marked a move toward détente in the Cold War. He presided over the worst economy in the four decades since the Great Depression, with growing inflation and a recession during his tenure. In one of his most controversial acts, he granted a presidential pardon to President Richard Nixon for his role in the Watergate scandal.

Leonard James Callaghan, Baron Callaghan of Cardiff, (27 March 1912 – 26 March 2005), often known as Jim Callaghan, served as Prime Minister of the United Kingdom from 1976 to 1979 and Leader of the Labour Party from 1976 to 1980.

Callaghan is, to date, the only British politician to have served in all four of the Great Offices of State, having been Chancellor of the Exchequer (1964–1967), Home Secretary (1967–1970), and Foreign Secretary (1974–1976) prior to his appointment as Prime Minister. As Prime Minister, he had some successes, but is mainly remembered for the "Winter of Discontent" of 1978–79. During a very cold winter, his battle with trade unions led to immense strikes that seriously inconvenienced the public, leading to his defeat in the polls by Conservative leader Margaret Thatcher. Callaghan was the last Prime Minister born before the First World War.

James Earl Carter Jr. (born October 1, 1924) is an American politician and philanthropist who served as the 39th president of the United States from 1977 to 1981. A Democrat, Carter has remained active in public life during his post-presidency, and in 2002 he was awarded the Nobel Peace Prize for his work in co-founding the Carter Center.

On his second day in office, Carter pardoned all the Vietnam War draft evaders. During Carter's term as president, two new cabinet-level departments, the Department of Energy and the Department of Education, were established. He established a national energy policy that included conservation, price control, and new technology. The end of his presidential tenure was marked by the 1979–1981 Iran hostage crisis, the 1979 energy crisis, the Three Mile Island nuclear accident, and the Soviet invasion of Afghanistan.

The Three Mile Island accident occurred on March 28, 1979, in reactor number 2 of Three Mile Island Nuclear Generating Station (TMI-2) in Dauphin County, Pennsylvania, near Harrisburg. It was the most significant accident in US commercial nuclear power plant history. The incident was rated a five on the seven-point International Nuclear Event Scale: Accident with wider consequences.

The accident crystallized anti-nuclear safety concerns among activists and the general public, and resulted in new regulations for the nuclear industry. It has been cited to have been a catalyst to the decline of a new reactor construction program, a slowdown that was already underway in the 1970s. The partial meltdown resulted in the release of radioactive gases and radioactive iodine into the environment.

Margaret Hilda Thatcher, Baroness Thatcher, (née Roberts; 13 October 1925 – 8 April 2013) was a British stateswoman who served as Prime Minister from 1979 to 1990. She was the longest-serving British prime minister of the 20th century and the first woman to hold that office. A Soviet journalist dubbed her "The 'Iron Lady'", a nickname that became associated with her uncompromising politics and leadership style.

Thatcher introduced a series of economic policies intended to reverse high unemployment and Britain's struggles in the wake of the Winter of Discontent and an ongoing recession. Her policies emphasised deregulation, flexible labour markets, privatisation of state-owned companies, and reducing the power of trade unions. Her popularity waned amid recession and rising unemployment, but victory in the 1982 Falklands War and the recovering economy brought a resurgence of support. She survived an assassination attempt in the Brighton hotel bombing in 1984.

Thatcher was re-elected for a third term in 1987, but her subsequent support for the Community Charge ("poll tax") was widely unpopular, and her views on the European Community were not shared by others in her Cabinet. She resigned in November 1990, after a leadership challenge.

Ronald Wilson Reagan (February 6, 1911 – June 5, 2004) was an American politician who served as the 40th president of the United States from 1981 to 1989. Prior to his presidency, he was a Hollywood actor and union leader before serving as the 33rd governor of California from 1967 to 1975. Soon after taking office, Reagan began implementing sweeping new political and economic initiatives. His supply-side economic policies, dubbed "Reaganomics", advocated tax rate reduction to spur economic growth, economic deregulation, and reduction in government spending. In his first term he survived an assassination attempt, spurred the War on Drugs, and fought public sector labor.

Foreign affairs dominated his second term, including ending the Cold War, the bombing of Libya, the Iran–Iraq War, and the Iran–Contra affair. He transitioned Cold War policy from détente to rollback by escalating an arms race with the USSR while engaging in talks with Gorbachev. The talks culminated in the INF Treaty, which shrank both countries' nuclear arsenals.

The Falklands War was a ten-week war between Argentina and the United Kingdom over two British dependent territories in the South Atlantic: the Falkland Islands, and its territorial dependency, the South Georgia and the South Sandwich Islands. It began on Friday, 2 April 1982, when Argentina invaded the Falkland Islands in an attempt to establish the sovereignty it had claimed over them.

On 5 April, the British government dispatched a naval task force to engage the Argentine Navy and Air Force before making an amphibious assault on the islands. The conflict lasted 74 days and ended with the Argentine surrender on 14 June 1982, returning the islands to British control. In total, 649 Argentine military personnel, 255 British military personnel, and three Falkland Islanders died during the hostilities.

The Chernobyl disaster was a catastrophic nuclear accident. It occurred on 25–26 April 1986 in the No. 4 light water graphite moderated reactor at the Chernobyl Nuclear Power Plant near the now-abandoned town of Pripyat, in northern Ukrainian Soviet Socialist Republic, Soviet Union, approximately 104 km (65 mi) north of Kiev.

The accident is considered the most disastrous nuclear power plant accident in history, both in terms of cost and casualties. It is one of only two nuclear energy accidents classified as a level 7 event (the maximum classification) on the International Nuclear Event Scale, the other being the Fukushima Daiichi nuclear disaster in Japan in 2011.
