The American Colonization Society (ACS), initially the Society for the Colonization of Free People of Color of America, was an American organization founded in 1816 by Robert Finley to encourage and support the repatriation of freeborn people of color and emancipated slaves to the continent of Africa. It was modeled on an earlier British colonization in Africa, which had sought to resettle London's "black poor".
The American Colonization Society was established in 1816 to address the prevailing view that free people of color could not integrate into U.S. society; their population had grown steadily following the American Revolutionary War, from 60,000 in 1790 to 300,000 by 1830.[2]: 26 Slaveowners feared that these free Black people might help their slaves to escape or rebel. In addition, many White Americans believed that African Americans were inherently inferior and should be relocated.[3]
