In 1933, Batista led an uprising called the Sergeants' Revolt, as part of the coup that overthrew the government of Gerardo Machado.
Machado was succeeded by Carlos Manuel de Céspedes y Quesada, who lacked a political coalition that could sustain him and was soon replaced.

A short-lived five-member presidency, known as the Pentarchy of 1933, was established.
The Pentarchy included a representative from each anti-Machado faction.
Batista was not a member, but controlled Cuba's armed forces.
Within days, the representative for the students and professors of the University of Havana, Ramón Grau San Martín, was made president—and Batista became the Army Chief of Staff, with the rank of colonel, effectively putting him in control of the presidency.
The majority of the commissioned officer corps were forced to retire or, some speculate, were killed.

Grau remained president for just over 100 days before Batista, conspiring with the U.S. envoy Sumner Welles, forced him to resign in January 1934.
Grau was replaced by Carlos Mendieta, and within five days the U.S. recognized Cuba's new government, which lasted eleven months.
Batista then became the strongman behind a succession of puppet presidents until he was elected president in 1940.
After Mendieta, succeeding governments were led by José Agripino Barnet (5 months) and Miguel Mariano Gómez (7 months) before Federico Laredo Brú ruled from December 1936 to October 1940.
