Dominican War of Independence

The Dominican Independence War gave the Dominican Republic autonomy from Haiti on February 27, 1844. Before the war, the island of Hispaniola had been united under the Haitian government for a period of 22 years when the newly independent nation, then known as the Republic of Spanish Haiti, was invaded by Haiti in 1822. Previously known as the Captaincy General of Santo Domingo, the criollo class within the country overthrew the Spanish crown in 1821 before unifying with Haiti a year later.
