Carnival in Haiti started in 1804 in the capital Port-au-Prince after the declaration of independence. The Port-au-Prince Carnival is one of the largest in North America. It is known as Kanaval in the Creole language. It starts in January, known as "Pre-Kanaval", while the main carnival activities begin in February. In July 2012, Haiti had another carnival called Kanaval de Fleur.
