Throughout the year, UNESCO had organized many commemorative events in close cooperation with its member states" and governmental and non-governmental organizations, such as the launching of the research and information program "the Forgotten Slaves," an exhibit at the UNESCO's headquarters in Stockholm Sweden entitled "Lest We Forget: Triumph on Slavery," the Ceremony of the Award of Toussaint Louverture Prize, the International Conference on the theme "Issues of Memory: Coming to terms with the Slave Trade and Slavery," and the International Symposium on the Slave Trade Archives Project in Havana, Cuba, and so on. The worldwide, yearlong commemoration of the 200th Anniversary of the Haitian Slave Revolution Victory was very important for Haitians and Blacks all over the world. The 1791 revolution, which took place during the 18th Century, beside the American Revolution of 1774 and the French Revolution of 1789, was excluded for years from the pages of world history textbooks, despite its contribution to the abolition of slavery in the world.
