Murderous coups are often called revolutions by the victors.
See also: Fulgencio Batista, the guy Fidel Castro's revolutionary coup threw out.
Senor Batista served as the democratically-elected president of Cuba in the early 1940s. He was voted out of office, and lived as a businessman in Miami. In 1952, he returned to Cuba and ran again. Facing defeat, he organized a coup.
According to Wikipedia, Bautista suspended the Cuban constitution, banned political parties, banned unions and the right to organize, censored the press, and made Cuba welcome to large American companies and the Mafia. During Batista's reign, the people were impoverished and illiteracy was at 70%, and the American government looked the other way because Batista was anti-Communist. Nowadays, literacy is at 95% and most Cubans have healthcare. Cuba is a totalitarian police state. But it was also before Castro.
