Americo-Liberian people (also known as Congo people or Congau people) are a Liberian ethnic group of African American, Afro-Caribbean, and liberated African origin. 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 themselves as Americo-Liberians.
Although the terms "Americo-Liberian" and "Congo" had distinct definitions in the nineteenth century, they are currently interchangeable and refer to an ethnic group composed of the descendants of the various free and ex-slave African American, Caribbean, recaptive, and Sierra Leone Creoles who settled in Liberia from 1822.
