The Haitian Revolution started in August 1791 with a slave rebellion in the northern part of the French colony of Saint-Domingue.

Toussaint Louverture, a former slave, emerged as the leader of the Haitian Revolution and played a crucial role in the fight for independence.

Charles Leclerc, Napoleon Bonaparte's brother-in-law, was sent to Haiti in 1802 to quell the rebellion.

The Battle of Vertières, fought on November 18, 1803, resulted in a decisive Haitian victory, securing their independence from French rule.

Haiti proclaimed its independence on January 1, 1804, becoming the first independent nation in the Americas to be led by people of African descent.

The Constitution of 1805, drafted under the leadership of Jean-Jacques Dessalines, established Haiti as a republic and abolished slavery.

Jean-Jacques Dessalines, a former lieutenant of Toussaint Louverture, took over the leadership of the Haitian Revolution after Louverture's capture by the French.

Jean-Jacques Dessalines proclaimed himself Emperor of Haiti in 1804 and ruled until his assassination in 1806.

Great Britain was the first country to recognize Haiti's independence in 1825, followed by France in 1825 and the United States in 1862.

Henri Christophe established the Kingdom of the North in 1811, ruling as King Henry I until his death in 1820.

Alexandre Pétion established the Republic of Haiti in 1806, serving as its president until his death in 1818.

Haiti was reunified as a single nation in 1820 under the leadership of Jean-Pierre Boyer, who became president of the unified republic.
