Robert Anthony Eden, 1st Earl of Avon, KG, MC, PC (12 June 1897 – 14 January 1977) was a British Conservative politician, who was Prime Minister from 1955 to 1957. He was also Foreign Secretary for three periods between 1935 and 1955, including during the Second World War. He is best known for his outspoken opposition to appeasement in the 1930s, his diplomatic leadership in the 1940s and 1950s, and the failure of his Middle East policy in 1956 that ended his premiership.

Eden's worldwide reputation as an opponent of appeasement, a "Man of Peace", and a skilled diplomat was overshadowed in the second year of his premiership when the United States refused to support the Anglo-French military response to the Suez Crisis, which critics across party lines regarded as an historic setback for British foreign policy, signalling the end of British predominance in the Middle East. Most historians argue that he made a series of blunders, especially not realizing the depth of opposition to military action by the US. Most historians say that Eden completely dominated the British decision-making process in the Suez crisis. However, Jonathan Pearson argues in Sir Anthony Eden and the Suez Crisis: Reluctant Gamble (2002) that Eden was more reluctant and less bellicose than most historians say.

James Francis Byrnes (May 2, 1882 – April 9, 1972) was an American politician from the state of South Carolina. During his career, Byrnes served as a US Representative (1911–1925), a US Senator (1931–1941), a Justice of the Supreme Court (1941–1942), Secretary of State (1945–1947), and 104th governor of South Carolina (1951–1955). He is one of very few politicians to serve in all three branches of the American national government while also being active in state government. He was a confidant of U.S. President Franklin D. Roosevelt, and was one of the most powerful men in American domestic and foreign policy in the mid-1940s.

Byrnes was born and reared in Charleston, South Carolina. Byrnes' father died shortly after Byrnes was born. His mother, Elizabeth McSweeney Byrnes, was an Irish-American dressmaker. At the age of fourteen, he left St. Patrick's Catholic School to work in a law office, and became a court stenographer. In 1906, he married the former Maude Perkins Busch of Aiken, South Carolina, and became an Episcopalian. Though they had no children, he was the godparent of James Christopher Connor.

Vyacheslav Mikhailovich Molotov (Russian: Вячесла́в Миха́йлович Мо́лотов; 9 March [O.S. 25 February] 1890 – 8 November 1986) was a Soviet politician and diplomat, an Old Bolshevik and a leading figure in the Soviet government from the 1920s, when he rose to power as a protégé of Joseph Stalin, to 1957, when he was dismissed from the Presidium (Politburo) of the Central Committee by Nikita Khrushchev. He served as Chairman of the Council of People's Commissars (Premier) from 1930 to 1941, and as Minister of Foreign Affairs from 1939 to 1949 and from 1953 to 1956. Molotov served for several years as First Deputy Premier in Joseph Stalin's cabinet. He retired in 1961 after several years of obscurity.

Molotov was the principal Soviet signatory of the Nazi-Soviet non-aggression pact of 1939 (also known as the Molotov-Ribbentrop Pact), after Britain and France repeatedly failed to join the Soviets in an anti-Nazi alliance, was involved in post-war negotiations where he became noted for his diplomatic skills, and knew of the Katyn massacre committed by the Soviet authorities. Following the aftermath of World War II (Great Patriotic War) Molotov kept his place, until 1949, as a leading Soviet diplomat and politician. In March 1949, after losing Stalin's favour, he lost the foreign affairs ministry to Andrei Vyshinsky. Molotov's relationship with Stalin deteriorated further, with Stalin complaining about Molotov's mistakes in a speech to the 19th Party Congress. However, after Stalin's death in 1953 Molotov was staunchly opposed to Khrushchev's de-Stalinisation policy. He defended his policies and the legacy of Stalin until his death in 1986, and harshly criticized Stalin's successors, especially Nikita Khrushchev.

Pierre Laval (French pronunciation: [pjɛʁ laval]; 28 June 1883 – 15 October 1945) was a French politician. He was four times President of the council of ministers of the Third Republic, twice consecutively.

Following France's surrender and Armistice with Germany in 1940, he served twice in the Vichy Regime as head of government. He signed orders permitting the deportation of foreign Jews from French soil to the Nazi death camps.

After Liberation (1945), Laval was arrested by the French government under General Charles de Gaulle, found guilty of high treason, and executed by firing squad. The controversy surrounding his political activities has generated a dozen biographies.

Laval was born 28 June 1883 at Châteldon, Puy-de-Dôme, in the northern part of Auvergne. His father worked in the village as a café proprietor, butcher and postman; he also owned a vineyard and horses. Laval was educated at the village school in Châteldon. At age 15, he was sent to a Paris lycée to study for his baccalauréat. Returning south to Lyon, he spent the next year reading for a degree in zoology.

Sir Winston Leonard Spencer-Churchill, KG, OM, CH, TD, PC, DL, FRS, Hon. RA (30 November 1874 – 24 January 1965) was a British Conservative politician and statesman known for his leadership of the United Kingdom during the Second World War. Widely regarded as one of the greatest wartime leaders of the century, he served as Prime Minister twice (1940–45 and 1951–55). A noted statesman and orator, Churchill was also an officer in the British Army, a historian, a writer, and an artist. He is the only British prime minister to have received the Nobel Prize in Literature, and was the first person to be made an Honorary Citizen of the United States.

Churchill was born into the aristocratic family of the Dukes of Marlborough. His father, Lord Randolph Churchill, was a charismatic politician who served as Chancellor of the Exchequer; his mother, Jenny Jerome, was an American socialite. As a young army officer, he saw action in British India, the Sudan, and the Second Boer War. He gained fame as a war correspondent and wrote books about his campaigns.
