African American history is the portion of American history that specifically discusses the African American or Black American ethnic group in the United States. Most African Americans are the descendants of captive Africans held in the United States from 1619 to 1865 who survived slavery. Others who are considered African American by the US government include voluntary immigrants from Africa, South America, and the Caribbean. African American history is celebrated in the United States during Black History Month.
The first African slaves were brought to Jamestown in 1619. The English settlers treated these captives as indentured servants and released them after a number of years. This practice was gradually replaced by the system of race based slavery used in the Caribbean. As servants were freed they became competition for resources. Additionally, released servants had to be replaced. This, combined with the still ambiguous nature of the social status of Blacks and the difficulty in using any other group of people as forced servants, led to the relegation of Blacks into slavery. Massachusetts was the first colony to legalize slavery in 1641.
