Answer:
American Colonization Society (ACS), originally known as the The Society for the Colonization of Free People of Color of America, was founded in 1816 by Robert Finley to encourage and support the migration of free African Americans to the continent of Africa. There were several factors that led to the establishment of the American Colonization Society. The number of free people of color grew steadily following the American Revolutionary War, from 60,000 in 1790 to 300,000 by 1830. Consequently, slaveowners grew increasingly concerned that free blacks might encourage or help their slaves to escape or rebel. In addition, most white Americans saw African Americans as "racially" inferior and felt that "amalgamation," or integration, of African Americans with white American culture was impossible and undesirable. This reinforced the notion that African Americans should be relocated to somewhere they could live free of prejudice, where they could be citizens. The African-American community and abolitionist movement overwhelmingly opposed the project. In most cases, African Americans' families had lived in the United States for generations, and their prevailing sentiment was that they were no more African than white Americans were European. Contrary to stated claims that emigration was voluntary, many African Americans, both free and enslaved, were pressured into emigrating. Indeed, enslavers sometimes manumitted their slaves on condition that the freedmen leave the country immediately. According to historian Marc Leepson, "Colonization proved to be a giant failure, doing nothing to stem the forces that brought the nation to Civil War." Between 1821 and 1847, only a few thousand African Americans, out of the then millions in the US, emigrated to what would become Liberia. Close to half of them died from tropical diseases. In addition, the transportation of the emigrants to the African continent, including the provisioning of requisite tools and supplies, proved very expensive.
