The Cuban Revolution of 1933 (Spanish: Revolución cubana de 1933), also called the Sergeants' Revolt, was a coup d'etat that occurred in Cuba in September 1933. It began as a revolt of sergeants and enlisted men in the military, who soon allied with student activists in the Directorio Estudiantil Universitario. The coup deposed Carlos Manuel de Céspedes y Quesada as president, installing a new government led by a five-man coalition, known as the Pentarchy of 1933.
After only five days, the Pentarchy gave way to the presidency of Ramón Grau, whose term is known as the One Hundred Days Government. The leader of the coup, Sergeant Fulgencio Batista, became the head of the armed forces and began a long period of influence on Cuban politics.
