Slavery has existed in all societies across the world. Throughout history, it has taken different forms. The most well-known and extreme form of historical slavery was the Transatlantic Slave Trade, which lasted for over 400 years and saw millions of Africans captured, sold and transported to the Americas and the Caribbean.
While slavery is now illegal, it is estimated that 21 million people worldwide are living as slaves today. Since 1949, the United Nations has marked the International Day for the Abolition on Slavery on 2 December, to remind people that slavery violates basic human rights and raise awareness of modern forms of slavery.
