The Second Empire of Haiti, officially known as the Empire of Haiti (, ), was a state which existed from 1849 to 1859. It was established by the then-President, former Lieutenant General and Supreme Commander of the Presidential Guards under President Riché, Faustin Soulouque, who, inspired by Napoleon, declared himself Emperor Faustin I on 26 August 1849 at the Cathedral of Our Lady of the Assumption in Port-au-Prince. Faustin's unsuccessful invasions (in part due to the diplomatic interference of the United States and Spain) in an attempt to reconquer the Dominican Republic (in 1849, 1850, 1855 and 1856), which had declared independence from Haiti in 1844, undermined his control over the country.
