Jean-Pierre Boyer (possibly February 15, 1776 July 9, 1850), a native of Saint-Domingue, was a soldier, one of the leaders of the Haitian Revolution, and President of Haiti from 1818 to 1843. He reunited the north and south of Haiti in 1820 and also invaded and took control of independent Santo Domingo, which brought all of Hispaniola under one government by 1822. Boyer managed to rule for the longest period of time of any of the revolutionary leaders of his generation.Born a free gens du couleur (or mulatto) in Hispaniola and educated in France, Boyer fought with Toussaint Louverture in the early years of the Haitian Revolution. He allied himself with André Rigaud, also a mulatto, in the latter's abortive insurrection against Toussaint to keep control in the south of Saint-Domingue.
