George Robert Acworth Conquest (15 July 1917 – 3 August 2015) was a British-American historian and poet.
A long-time research fellow at Stanford University's Hoover Institution, Conquest was most notable for his work on the Soviet Union. His books included The Great Terror: Stalin's Purges of the 1930s (1968); The Harvest of Sorrow: Soviet Collectivisation and the Terror-Famine (1986); and Stalin: Breaker of Nations (1991). He was also the author of two novels and several collections of poetry.
Conquest was born in Great Malvern, Worcestershire, to an American father, Robert Folger Wescott Conquest, and an English mother, Rosamund Alys Acworth. His father served in an American Ambulance Field Service unit with the French Army in World War I, and was awarded the Croix de Guerre, with Silver Star in 1916.
Conquest was educated at Winchester College, where he won an exhibition to study Philosophy, Politics and Economics (PPE) at Magdalen College, Oxford. He took a gap year, spending time at the University of Grenoble and in Bulgaria, and returning to Oxford in 1937, where he joined the Communist Party of Great Britain and the Carlton Club. He was awarded an MA in PPE and a DLitt in history.
In Lisbon on an American passport at the outbreak of the Second World War, Conquest returned to England. As the Communist Party of Great Britain denounced the war in 1939 as imperialist and capitalist, Conquest broke with it and was commissioned into the Oxfordshire and Buckinghamshire Light Infantry on 20 April 1940, serving with the regiment until 1946.
In 1943 he was posted to the School of Slavonic and East European Studies (later part of University College London) to study Bulgarian. The following year he was posted to Bulgaria as a liaison officer to the Bulgarian forces fighting under Soviet command, attached to the Third Ukrainian Front, then to the Allied Control Commission. At the end of the war, he joined the Foreign Office, returning to the British Legation in Sofia where he remained as the press officer.
