In 1843, the new Haitian president, Charles Rivière-Hérard, exiled or imprisoned the leading ''Trinitarios'' (Trinitarians). After subduing the Dominicans, Rivière-Hérard, a mulatto, faced a rebellion by blacks in Port-au-Prince. Haiti had formed two regiments composed of Dominicans from the city of Santo Domingo; these were used by Rivière-Hérard to suppress the uprising.
