The Washington anchors off Port-au-Prince and Marines come ashore

On 28 July 1915 the American vessel Washington cast anchor in the harbour of Port-au-Prince and its troops landed. They described themselves as liberators. The occupation lasted until 1934, and its central difficulty was what the Marines called the pacification of the peasantry. Thousands of country people were forced into hard labour on the roads and thousands were killed. In the north large numbers were sent to a concentration camp at Chalbert. Among the improvements the occupiers took credit for was the looting of temples and the destruction of the images of African ancestors. The link that American opinion had already drawn between race, religion and despotism is what prepared the ground for the landing, and the men who came ashore had read the same books the public had. When the Americans withdrew in 1934 the work of civilising the country was handed to a police force they had built, which was the most durable thing they left.

The fighting stopped on 11 November 1918. The war had lasted 1,563 days, killed some ten million soldiers, wounded twenty million more and consumed over three hundred billion dollars. It destroyed the Hohenzollerns in Germany, the Hapsburgs in Austria and the Romanovs in Russia, and in its final hours new governments were forming in Vienna, Warsaw, Budapest, Prague and Dublin while crowds filled the streets of Berlin and Petersburg. Kennedy opens his history of the American 1930s at this date because Herbert Hoover opened his memoirs the same way. The first sentence of those memoirs states that the primary cause of the Great Depression was the war of 1914 to 1918. Everything that followed for the United States, the debt, the tariffs, the closed door to immigrants and the refusal to join the League of Nations, was a reaction to those fifty two months.

United States marines landed at Port-au-Prince in 1915 and stayed until 1934. German and French capitalists were eliminated from the country in favour of American interests defined by the Monroe doctrine. In the plains American companies monopolised sugar, fruit and sisal for export, and large landed property consolidated around them. Peasants were dispossessed of land they occupied or rented. The occupiers restored compulsory labour for building roads and railways. The consequences ran in four directions. Smallholding peasantry broke up. The labour freed by that process became seasonal hands on the plantations. Migrants left for Cuba and the Dominican Republic, where cheap Haitian labour served capital in both countries. Others gathered in the towns, above all in Port-au-Prince, which from then on concentrated economic activity. Inside the state the senior posts filled with light-skinned men at the same moment as the economic position of the same families strengthened. The colour question came back into political life through that door.

On 28 July 1915 a crowd broke into the French embassy in Port-au-Prince, found President Vilbrun Guillaume Sam hiding in a bathroom, dragged him into the street and tore him to pieces. The day before, Sam had ordered the killing of 167 political prisoners taken from elite families, among them the former president Oreste Zamor. Those executions produced the rising that killed him. In Washington, Woodrow Wilson learned of it and feared that Rosalvo Bobo, whom his advisers took for a German sympathiser, would take power. On 29 July he ordered the Marines to occupy Haiti. The stated reason was humanitarian, the restoring of order in a country said to be incapable of governing itself. The working reasons were strategic: keeping Germany out of the Caribbean during the European war, holding the Windward Passage that guards the approach to the Panama Canal, and protecting American money already placed in Haiti. The occupation ran nineteen years. A century of Haitian self government, disorderly as it had been, ended inside a week.
