Christian Rakovsky, Bulgarian physician, journalist, and politician, Soviet Ambassador to France (b. 1873)
Christian Georgievich Rakovsky (Russian: Христиа́н Гео́ргиевич Рако́вский; Bulgarian: Кръстьо Георгиев Станчев, Христия́н Георги́ев Рако́вски; August 13 [O.S. August 1] 1873 – September 11, 1941) was a Bulgarian-born socialist revolutionary, a Bolshevik politician and Soviet diplomat and statesman; he was also noted as a journalist, physician, and essayist. Rakovsky's political career took him throughout the Balkans and into France and Imperial Russia; for part of his life, he was also a Romanian citizen.

A lifelong collaborator of Leon Trotsky, he was a prominent activist of the Second International, involved in politics with the Bulgarian Workers' Social Democratic Party, Romanian Social Democratic Party, and the Russian Social Democratic Labour Party. Rakovsky was expelled at different times from various countries as a result of his activities, and, during World War I, became a founding member of the Revolutionary Balkan Social Democratic Labor Federation while helping to organize the Zimmerwald Conference. Imprisoned by Romanian authorities, he made his way to Russia, where he joined the Bolshevik Party after the October Revolution, and, as head of the Rumcherod, unsuccessfully attempted to generate a communist revolution in the Kingdom of Romania. Subsequently, he was a founding member of the Comintern, served as head of government in the Ukrainian SSR, and took part in negotiations at the Genoa Conference.

He came to oppose Joseph Stalin and rallied with the Left Opposition, being marginalized inside the government and sent as Soviet ambassador to London and Paris, where he was involved in renegotiating financial settlements. He was ultimately recalled from France in autumn 1927, after signing his name to a controversial Trotskyist platform which endorsed world revolution. Credited with having developed the Trotskyist critique of Stalinism as "bureaucratic centrism", Rakovsky was subject to internal exile. Submitting to Stalin's leadership in 1934 and being briefly reinstated, he was nonetheless implicated in the Trial of the Twenty One (part of the Moscow Trials), imprisoned, and executed by the NKVD during World War II. He was rehabilitated in 1988, during the Soviet Glasnost period.
