How Fidel Castro maintained his power for five decades

Have a general understanding of Cuban revolution, and write an essay focusing on how Fidel Castro, the Former Prime Minister of Cuba, maintained his power for over 52 years until 2008. You should talk about media censorship & thought control, violent suppression he used. Also, he was supported by many, which explained his long-term presidency. You should add how he was supported by people in the essay. Try to incorporate at least three primary sources into the essay. If you can, try to use any information from the book “The Cuba Reader: History, Culture, Politics.” (attached) You don’t have to finish by Sunday. But at least give me something by that time.
