The modern Haitian diaspora starts with people leaving Duvalier

The Haitian communities abroad that now send money home began as an escape. Through the 1960s educated Haitians left in numbers as Francois Duvalier fastened his grip, and the Haitian population of the United States grew from about five thousand in 1960 to about thirty thousand in 1970. The people who went were the ones a poor country can least spare: lawyers, doctors, teachers, engineers, civil servants and owners of businesses. Schools and hospitals lost the staff who ran them and the state lost the people who knew how to make it work. The movement never stopped. By the early twenty first century more than 2.5 million Haitians lived outside Haiti, roughly a million in the Dominican Republic and roughly a million in the United States, about three hundred thousand in Cuba, and close to a hundred thousand each in the Bahamas, Canada and France. Money sent back by those households became one of the largest sources of income in the Haitian economy.

When the supreme court declined the presidency for a second time, the Haitian army handed it to Major General Paul Magloire, who had been running the country since 1950. He declared a state of siege and dissolved the legislature. He lasted a week. On the Monday, businesses across Port-au-Prince failed to open. Bank clerks and schoolteachers stayed at home. The Duvalierist drivers association pulled every taxi and camionnette off the road, and peasants who had heard that something dangerous was loose in the capital brought no food to market. Magloire walked the length of the waterfront with his staff and a submachine gun in his arms. Shops opened as he came near and shut again behind him. He had no intention of shooting Haitians and everyone watching understood that. On the Wednesday he passed executive power back to the chief justice, kept his commission as a general, and set up in the barracks. Junior officers arrived with pistols to tell him the time had come. A transport plane was waiting at Bowen Field, and he flew south to Kingston.

Speaking in Havana in 1968, the Haitian poet Rene Depestre described the negritude of the Duvalier government as a delirious mystification. His argument was that the regime's language about race concealed an ordinary struggle for power between rival groups inside the Haitian propertied class, and that dressing it as the triumph of the black majority was a service performed for reaction. Depestre had grown up inside the intellectual world he was attacking. He had been a young radical in Port-au-Prince in 1946, expelled and exiled repeatedly, and he had argued with Aime Cesaire, for whom negritude meant something other than a state doctrine. From Cuba he broadcast two hours a day into Haiti in Kreyol. The charge carried weight because it came from the left rather than from the elite the regime liked to name as its enemy. It said that a black government could reproduce the same order under a different flag.

In 1968 Michel-Rolph Trouillot left Haiti for Brooklyn to get away from the Duvalier regime. He was one of a great many student activists who went that decade, into a New York that was becoming the second city of Haitian intellectual life. He came from a family of historians and had grown up inside the argument about what his country was. In exile he trained as an anthropologist, and the books he wrote afterwards changed the terms in which Haiti could be described. Haiti: State Against Nation set out the Duvalier state as a system rather than a personality. Silencing the Past asked why Western historians had treated the Haitian revolution as an event that could not have happened, and it is now read in universities that teach nothing else about Haiti at all. He held a chair at Chicago and died in 2012. The dictatorship that drove him out produced, at one remove, the historian who explained it.
