The Haitian Revolution was one of the most important events in modern history. Between 1791

and 1804, Black insurgents in the French Caribbean colony of Saint-Domingue overthrew

slavery, broke away from the French empire, and founded the free nation of Haiti, the first polity

led by people of African ancestry in the Western Hemisphere. And yet, international recognition

of Haitian independence did not come for another two decades, and, even then, only through a

punishing French law: the ordinance of April 17, 1825. That ordinance granted French

recognition to Haiti, but with two extraordinarily burdensome conditions. First, Haiti would have

to pay a massive indemnity of 150 million francs to former French plantation owners who

demanded compensation for landed and human “property” lost during the Haitian Revolution.

Second, Haiti was required to adopt a neo-mercantilist tariff called the “half-duty,” which slashed

customs duties on French goods by 50% at the expense of Haitian state revenue. Ratified by the Haitian government under French military threat, the ordinance undermined Haitian sovereignty, battered its economy, and hindered public investment in education and infrastructure. Today, the ordinance remains highly controversial, as activists demand that France pay financial reparations to Haiti.

Historians have long studied the indemnity, but we know very little about the half-duty. My

paper examines not only why the neo-imperialist tariff was established, but, importantly, how it

generated intense political conflict between France and Haiti. Opposition to the half-duty was

surprisingly robust as Haitian state officials and journalists challenged its legitimacy in the name

of Haitian national sovereignty. In fact, the political controversy over of the tariff became so

heated that France eventually abandoned the project altogether. This paper highlights how

Haitians drew on revolutionary ideas of sovereignty to mount an effective opposition to

nineteenth-century French commercial empire.
