Ruth Bonner, Soviet Communist activist, sentenced to a labor camp during Joseph Stalin's Great Purge (died 1987)

Ruf Grigorievna Bonner, also known as Ruth Bonner, was a Soviet Communist activist who spent eight years in a labor camp during Joseph Stalin's Great Purge. She was the mother of the human rights activist Yelena Bonner and the mother-in-law of physicist and dissident Andrei Sakharov.

Joseph Vissarionovich Stalin was a Soviet politician and revolutionary who led the Soviet Union from 1924 until his death in 1953. He held office as General Secretary of the Communist Party from 1922 to 1952 and as the fourth premier from 1941 until his death. Despite initially governing the country as part of a collective leadership, he ultimately consolidated power to become an absolute dictator by the 1930s. Stalin codified the party's official interpretation of Marxism as Marxism–Leninism, while the totalitarian political system he created is known as Stalinism.

The Great Purge or Great Terror, also known as the Year of '37 and the Yezhovshchina, was a political purge in the Soviet Union from 1936 to 1938. After the assassination of Sergei Kirov by Leonid Nikolaev in 1934, Joseph Stalin launched a series of show trials known as the Moscow trials to remove suspected dissenters from the Communist Party of the Soviet Union. The term "great purge" was popularized by historian Robert Conquest in his 1968 book, The Great Terror, whose title alluded to the French Revolution's Reign of Terror.
