Many Haitians left the country to escape abuses and poor economic conditions under the rule of Francois "Papa Doc" Duvalier. Option 3 is correct.
François Duvalier was the President of Haiti from 1957 to 1971. He was elected president in 1957 on a populist and black nationalist platform. In 1958, his regime became totalitarian and despotic. An undercover government death squad, the Tonton Macoute, murdered opponents indiscriminately, and was considered so pervasive that Haitians became highly fearful of conveying dissent, even in private.
