Freetown was use to facilitate ________ from 1822 to early 20th century.

Freetown, which is the capital city of Sierra Leone, was used to facilitate the settlement of freed slaves from 1822 to the early 20th century. In the late 18th and early 19th centuries, several British organizations and individuals began advocating for the abolition of the transatlantic slave trade and the emancipation of enslaved Africans. After the British Parliament passed the Slavery Abolition Act in 1833, which abolished slavery throughout the British Empire, many enslaved Africans were freed and needed a place to settle. In 1822, the British government established a settlement for freed slaves in Freetown, which had been founded by the Sierra Leone Company in 1792 as a home for repatriated Africans and other people of African descent. The freed slaves, known as the "recaptives," were resettled in Freetown and other parts of Sierra Leone. Freetown became a center of resettlement for freed slaves from all over West Africa, and the settlement of the recaptives continued until the early 20th century. Freetown also became a hub for the anti-slavery movement and the promotion of Christianity, as many of the recaptives were evangelized by Christian missionaries and educated in Christian schools. In summary, Freetown was used to facilitate the settlement of freed slaves from 1822 to the early 20th century, as the British government established a settlement for them in the city.
