The Igbo in the Atlantic slave trade became one of the main ethnic groups enslaved in the era lasting between the 16th and late 19th century. Located near indigenous Igbo territory, the Bight of Biafra (also known as the Bight of Bonny), became the principal area in obtaining Igbo slaves. The Bights major slave trading ports were located in Bonny and Calabar; a large number of these slaves Igbo. Slaves, kidnapped or bought from fellow Africans, were taken to Europe and the Americas by European slave traders. An estimated 14.6% of slaves were taken from the Bight of Biafra between 1650 and 1900, the third greatest percentage in the era of the transatlantic slave trade.
