Peter II of Yugoslavia (September 6, 1923 — November 3, 1970), was the king of Yugoslavia from 1934–1945. From 1934–1941 his cousin Paul ruled as regent but was removed after Yugoslavia joined the Axis powers for two days. The axis invaded Yugoslavia and the Yugoslav government went into exile. The government never returned to the country because a communist government, the Federal People's Republic of Yugoslavia, was formed after the country was liberated.
Peter died in exile in the United States in 1970.
