Afro-American settlement in Africa
Ex-slave repatriation 
The immigration of African American, Caribbean, and Black British slaves to Africa occurred mainly during the late 18th century to mid-19th century. In the cases of Liberia and Sierra Leone both were established by former slaves who were repatriated to African within a 28 year period.
However, other ex-slaves were repatriated from other European territories and colonies. The Tabom people are descendants of Afro-Brazilian ex-slaves who were either voluntarily or forcefully deported to Africa (some of them being deported following the Bahia Malê Revolt in 1835); they constitute a minority ethnic group on the coastal regions of modern-day Ghana and Togo.
Post-slavery settlement 
Following the end of slavery in the Americas, numerous movements for African-American settlement in Africa sprung up and fluctuated in popularity, many of them involving Liberia. African American abolitionist and Army officer Martin Delany supported a project for African-American immigration to Liberia later in his lifetime. However, it declined by the end of the 19th century following a string of hoaxes and fraudulent activities associated with the movement.
The Back-to-Africa movement achieved popularity again with Jamaican activist Marcus Garvey and his UNIA-ACL, who advocated racial pride amongst African-Americans in the United States and pressed for repatriation of slave descendants to Liberia and Sierra Leone. The movement fell apart by the end of the 1920s, but influenced both the black supremacist Nation of Islam and the Rastafari movement; the latter, a Jamaican which saw Haile Selassie I, the emperor of Ethiopia, as a reincarnation of Jesus and Marcus Garvey as a patron saint, managed to secure a settlement in Shashamane, which exists to this day and constitutes around 200+ individuals out of an urban population of 95,000+.
Another Afro-American settlement is concentrated in Accra, Ghana, which has over 1000 Afro-American residents, primarily originating from the United States, who reside in the country on work permits, with a few on permanent resident status. Accra has long attracted Afro-American tourists since the country became the first African country to gain independence from the United Kingdom in 1957, and the government has made controversial overtures to gain more Afro-American residents and tourists.
