Ioseb Besarionis dze Jughashvili was the birthname of which leader of the Soviet Union?

Joseph Vissarionovich Stalin (born Ioseb Besarionis dze Jughashvili; 18 December 1878 – 5 March 1953) was a Soviet politician and revolutionary who led the Soviet Union from 1924 until his death in 1953. He held power as General Secretary of the Communist Party from 1922 to 1952 and Chairman of the Council of Ministers from 1941 until his death. Initially governing as part of a collective leadership, Stalin consolidated power to become dictator by the 1930s; he formalized his Leninist interpretation of Marxism as Marxism-Leninism, while the totalitarian political system he established became known as Stalinism.

Widely considered one of the 20th century's most significant figures, Stalin was the subject of a pervasive personality cult within the international Marxist–Leninist movement, for whom Stalin was a champion of socialism and the working class. Since the dissolution of the Soviet Union in 1991, Stalin has notably retained popularity in Russia and Georgia as a victorious wartime leader who established the Soviet Union as a major world power. Conversely, his totalitarian government has been widely condemned for overseeing mass repressions, ethnic cleansing, executions, and famines which caused the deaths of millions.
