It is against this background that the International Day for the Remembrance of the Slave Trade and its Abolition is commemorated on 23 August each year. It was first celebrated in a number of countries, in particular in Haiti (23 August 1998) and Gorée Island in Senegal (23 August 1999).
This International Day is intended to inscribe the tragedy of the slave trade in the memory of all peoples. In accordance with the goals of the intercultural project "The Routes of Enslaved Peoples", it should offer an opportunity for collective consideration of the historic causes, the methods and the consequences of this tragedy, and for an analysis of the interactions to which it has given rise between Africa, Europe, the Americas and the Caribbean.  That date was chosen by the adoption of resolution 29 C/40 by the Organization's General Conference at its 29th session. Circular CL/3494 of July 29, 1998, from the Director-General invited Ministers of Culture to promote the day. The date is significant because, during the night of August 22 to August 23, 1791, on the island of Saint Domingue (now known as Haiti), an uprising began which set forth events which were a major factor in the abolition of the transatlantic slave trade.
UNESCO Member States organize events every year on that date, inviting participation from young people, educators, artists and intellectuals. As part of the goals of the intercultural UNESCO project, "The Slave Route", it is an opportunity for collective recognition and focus on the "historic causes, the methods and the consequences" of slavery. Additionally, it sets the stage for analysis and dialogue of the interactions which gave rise to the transatlantic trade in human beings between Africa, Europe, the Americas and the Caribbean.
