Peter II

(born Sept. 6, 1923, Belgrade, Kingdom of Serbs, Croats, and Slovenes—died Nov. 3, 1970, Los Angeles, Calif., U.S.) Last king of Yugoslavia. The son of Alexander I, he became titular king on his father's assassination (1934), but he ruled under the regency of his uncle Prince Paul (1893–1976). After a coup deposed Paul (1941), Peter ruled for several weeks until the German invasion forced him to flee to London. He led a government-in-exile until the Yugoslav monarchy was abolished in 1945. He moved to the U.S., where he worked in public relations.
