Task: Explanation
Input (English): Americo-Liberians, or the Congo people in Liberian English, are a Liberian ethnicity of African-American, Afro-Caribbean, and liberated African descent. The sister ethnic group of Americo-Liberians are the Sierra Leone Creole people, who shared similar ancestry and related culture. Americo-Liberians trace their ancestry to free-born and formerly enslaved African Americans who immigrated 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 present-day Côte d'Ivoire.) Although the terms "Americo-Liberian" and "Congo" had distinct definitions in the nineteenth century, the terms "Americo-Liberian" and "Congo" 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. Question: The Republican Party was known to be made up primarily of ethnic groups composed of descendants who settled in Liberia from what year? Answer: 1822
