years old, members of a Creole elite of Santo Domingo's capital proclaimed its independence from Spanish rule, calling themselves Haití Español. Historians today call this elite's brief courtship with sovereignty the Ephemeral Independence. The most prominent leader of the coup against Spanish colonial government was one of its former supporters, José Núñez de Cáceres. These individuals were tired of being ignored by the Crown, and some were also concerned with the new liberal turn in Madrid. Their deed was not an isolated event.

Haitian politicians wanted to keep the island out of the hands of European imperial powers and thus a way to safeguard the Haitian Revolution . Haiti's President Jean-Pierre Boyer sent an army that took over the eastern portion of Hispaniola. Struggles between Boyer and the old colonial helped produce a migration of planters and elite. It also led to the closing of the university. Following the bourgeoisie custom of sending promising sons abroad for education, the Duartes sent Juan Pablo to the United States and Europe in 1828 . While on board the ship, the captain would insinuate to Duarte that his people were cowards and repeatedly referred to him as "Haitian," to which Duarte rejected
