Olaudah Equiano (c.1745 –1797) was a prominent African involved in the British movement towards the abolition of the slave trade. Enslaved as a young man, he purchased his freedom and worked as an author, merchant and explorer in South America, the Caribbean, the Arctic, the American colonies, and England. He spent two months in Norwich in 1794.
