What is "mississippi-in-africa"

Mississippi-in-Africa was a colony on the Pepper Coast founded in the 1830s by the Mississippi Colonization Society of the United States and settled by freed African-American slaves. In the late 1840s, some 300 former slaves from Prospect Hill Plantation and other Isaac Ross properties in Jefferson County, Mississippi were the largest single group of migrants to the new colony.

They became part of the Americo-Liberians, an ethnic group who formed a political and economic elite that dominated what became the country of Liberia into the late 20th century. The colony was located in what is present-day Sinoe County, Liberia.
