The 1944 Bulgarian coup d'état, also known as the 9 September coup d'état (Bulgarian: Деветосептемврийски преврат, Devetoseptemvriyski prevrat), was the forcible change of the government of Kingdom of Bulgaria carried out on the eve of 9 September 1944. In Communist Bulgaria it was called People's Uprising of 9 September (Деветосептемврийско народно въстание) – on the grounds of the broad unrest, and Socialist Revolution (Социалистическа революция) – as it was a turning point politically and the beginning of radical reforms towards socialism.
