Answer:
between 1662 and 1807 British and British colonial ships purchased an estimated 3,415,500 Africans. Of this number, around 2,964,800 survived the 'middle passage' and were sold into slavery in the Americas.
The transatlantic slave trade was the largest forced migration in human history and completely changed Africa, the Americas and Europe.
Until the 1730s, London dominated the British trade in enslaved people. It continued to send ships to West Africa until the end of the trade in 1807.
Between 1699 and 1807, British and British colonial ports mounted 12,103 slaving voyages - with 3,351 setting out from London.
