Olaudah Equiano was born in Essaka, an Igbo village in the kingdom of Benin (now Nigeria) in 1745. His father was one of the province's elders who decided disputes. According to James Walvin "Equiano described his father as a local Igbo eminence and slave owner".
When he was about eleven, Equiano was kidnapped and after six months of captivity he was brought to the coast where he encountered white men for the first time. Equiano later recalled in his autobiography, Narrative of the Enslavement of a Native of America (1787): "The first object which saluted my eyes when I arrived on the coast, was the sea, and a slave ship, which was then riding at anchor, and waiting for its cargo. These filled me with astonishment, which was soon converted into terror, when I was carried on board. I was immediately handled, and tossed up to see if I were sound, by some of the crew; and I was now persuaded that I had gotten into a world of bad spirits, and that they were going to kill me. Their complexions, too, differing so much from ours, their long hair, and the language they spoke, (which was very different from any I had ever heard) united to confirm me in this belief. Indeed, such were the horrors of my views and fears at the moment, that, if ten thousand worlds had been my own, I would have freely parted with them all to have exchanged my condition with that of the meanest slave in my own country."
Olaudah Equiano was placed on a slave-ship bound for Barbados. "I was soon put down under the decks, and there I received such a greeting in my nostrils as I had never experienced in my life; so that, with the loathsomeness of the stench, and crying together, I became so sick and low that I was not able to eat, nor had I the least desire to taste anything. I now wished for the last friend, death, to relieve me; but soon, to my grief, two of the white men offered me eatables; and, on my refusing to eat, one of them held me fast by the hands, and laid me across, I think, the windlass, and tied my feet, while the other flogged me severely. The closeness of the place, and the heat of the climate, added to the number in the ship, which was so crowded that each had scarcely room to turn himself, almost suffocated us. The air soon became unfit for respiration, from a variety of loathsome smells, and brought on a sickness among the slaves, of which many died. The wretched situation was again aggravated by the chains, now unsupportable, and the filth of the necessary tubs, into which the children often fell, and were almost suffocated. The shrieks of the women, and the groans of the dying, rendered the whole a scene of horror almost inconceivable."
After a two-week stay in the West Indies Equiano was sent to the English colony of Virginia. In 1754 he was purchased by Captain Henry Pascal, a British naval officer. He was given the new name of Gustavus Vassa and was brought back to England. According to his biographer, James Walvin: "For seven years he served on British ships as Pascal's slave, participating in or witnessing several battles of the Seven Years' War. Fellow sailors taught him to read and write and to understand mathematics. He was also converted to Christianity, reading the Bible regularly on board ship. Baptized at St Margaret's Church, Westminster, on 9 February 1759, he struggled with his faith until finally opting for Methodism."
By the end of the Seven Years' War he reached the rank of able seaman. Although he was freed by Pascal he was re-enslaved in London in 1762 and shipped to the West Indies. For four years he worked for a Montserrat based merchant, sailing between the islands and North America. "I was often a witness to cruelties of every kind, which were exercised on my unhappy fellow slaves. I used frequently to have different cargoes of new Negroes in my care for sale; and it was almost a constant practice with our clerks, and other whites, to commit violent depredations on the chastity of the female slaves; and these I was, though with reluctance, obliged to submit to at all times, being unable to help them." James Walvin points out that "Equiano... also trading to his own advantage as he did so. Ever alert to commercial openings, Equiano accumulated cash and in 1766 bought his own freedom."
Equiano now worked closely with Granvile Sharpe and Thomas Clarkson in the Society for the Abolition of the Slave Trade. Equiano spoke at a large number of public meetings where he described the cruelty of the slave trade. In 1787 Equiano helped his friend, Offobah Cugoano, to published an account of his experiences, Narrative of the Enslavement of a Native of America. Copies of his book was sent to George III and leading politicians. He failed to persuade the king to change his opinions and like other members of the royal family remained against abolition of the slave trade.
Equiano published his own autobiography, The Life of Olaudah Equiano the African in 1789. He travelled throughout England promoting the book. It became a bestseller and was also published in Germany (1790), America (1791) and Holland (1791). He also spent over eight months in Ireland where he made several speeches on the evils of the slave trade. While he was there he sold over 1,900 copies of his book.
David Dabydeen has argued: "With Thomas Clarkson, William Wilberforce and Granville Sharpe, Equiano was a major abolitionist, working ceaselessly to expose the nature of the shameful trade. He travelled throughout Britain with copies of his book, and thousands upon thousands attended his readings. When John Wesley lay dying, it was Equiano's book he took up to reread."
On 7th April 1792 Equiano married Susanna Cullen (1761-1796) of Soham, Cambridgeshire. The couple had two children, Anna Maria (16th October 1793) and Johanna (11th April 1795). However, Anna Maria died when she was only four years old. Equiano's wife died soon afterwards. During this period he was a close friend of Thomas Hardy, secretary of the London Corresponding Society. Equiano became an active member of this group that campaigned in favour of universal suffrage.
Olaudah Equiano was appointed to the expedition to settle former black slaves in Sierra Leone, on the west coast of Africa. However, he died at his home at Paddington Street, Marylebone, on 31st March, 1797 before he could complete the task.
