In 1940, under pressure from Germany and Hungary, Romania was forced to join the Axis, another reason being the German invasion of Romania on October 8. The Romanian Minister of Defense, Ion Antonescu, was created President of Rumania, and it became a German protectorate. The Rumanians fought on the Eastern Front from 1941 onwards, and in 1944, when the Soviet Union invaded Romania, they fought the Russians until a coup on August 23 overthrew Antonescu's dictatorship. The Rumanians stopped fighting, and when the Germans bombed Bucuresti, they changed sides. Most of the Rumanian armies surrendered to the Soviets, although some fought the Germans afterwards.
