What were the causes and issues in the Cuban revolution?

Answer 1

I assume you mean the Cuban Revolution of 1956-59? With Castro and Guevara?

It was against the rule of Batista. The whole country had enormous infant mortality, and the vast majority of the country had no electricity, and couldn't read or write. The followers of Batista, and Batista himself lived in luxery, with these huge houses, and gave money to the American banks. Meanwhile the vast majority of Cuba couldn't afford to feed themselves or their family.

I'd like to point out that since the Cuban Revolution, Cuba has the best health care, and lowest Infant Mortality Rate in the world. Better than America even.

I suggest you watch Che' Part 1, and the Motorcycle Diaries, and read Fidel and Che, by Simon Ried Henry, they'll give you a good insight into the revolution, and the reasons for it. I would suggest Che' Part 2, but it focuses on Guevara's time in Bolivia.
