Fulgencio Batista initially rose to power as part of the 1933 Revolt of the Sergeants that overthrew the provisional government of Carlos Manuel de Céspedes y Quesada. He then appointed himself chief of the armed forces, with the rank of colonel, and effectively controlled the five-member Presidency. He maintained this control through a string of puppet presidents until 1940, when he was himself elected President of Cuba on a populist platform. He then instated the 1940 Constitution of Cuba, considered progressive for its time, and served until 1944. After finishing his term he lived in Florida, returning to Cuba to run for president in 1952. Facing certain electoral defeat, he led a military coup that preempted the election.

source: Law's Empire
text: Law's Empire Law's Empire is a 1986 text in legal philosophy by the late Oxford scholar Ronald Dworkin which continues his criticism of the philosophy of legal positivism as promoted by H.L.A. Hart during the middle to late 20th century. The book notably introduces Dworkin's Judge Hercules as an idealized version of a jurist with extraordinary legal skills who is able to challenge various predominating schools of legal interpretation and legal hermeneutics prominent throughout the 20th century. Judge Hercules is eventually challenged by Judge Hermes, another idealized version of a jurist who is affected by an affinity to respecting historical legal meaning arguments which do not affect Judge Hercules in the same manner. Judge Hermes' theory of legal interpretation is found by Dworkin in the end to be inferior to the approach of Judge Hercules.
