"At the dawn of the 21st century, in 2001, the international community recognized the slave trade as a crime against humanity. Throughout 2007, the United Kingdom commemorated the bicentennial of the abolition of her slave trade. On 25 March 2008, the United Nations observed the first annual worldwide commemoration of the International Day of Remembrance of the Victims of Slavery and the Transatlantic Slave Trade, and that year also marks the bicentenary of the U.S. official end of the international slave trade."
