Americo-Liberian people or Congo people or Congau people in Liberian English, are a Liberian ethnic group of African-American, Afro-Caribbean, and Liberated African descent. The sister ethnic group of Americo-Liberians are the Sierra Leone Creole people, who share similar ancestry and related culture. Americo-Liberians trace their ancestry to free-born and formerly enslaved African Americans who emigrated in the 19th century to become the founders of the state of Liberia. They identified there as Americo-Liberians. Some African Americans following resettlement in Canada also participated as founding settlers in Sierra Leone and other Recaptive repatriates settled in present-day Côte d'Ivoire.
