International Day of Remembrance of the Victims of Slavery and the Transatlantic Slave Trade is a United Nations International observance designated in 2007 to be marked on 25 March every year.
The day honors and remembers those who suffered and died as a consequence of the transatlantic slave trade, which has been called "the worst violation of human rights in history", in which over 400 years more than 15 million men, women and children were the victims. (Wikipedia 2022).
