The war of Dominican independence was the historical process that began with the proclamation of the Dominican Republic and its separation from Haiti in February 1844. During the 22 years preceding independence, the entire island of Hispaniola was under the dominion of Haiti, a working operation in 1821 in the eastern part of the island.
After the efforts by Dominican patriots to make the country independent from the domain, several military actions that took place between 1844 and 1856 ended up consolidating in the republic as a new state. The Haitians tried several times to dominate the newly created republic with failed results until in 1867 Haiti recognized Dominican independence.
