Slavery existed in the USA from the colonial period until 1865. The document outlines the history and structure of slavery, including the forced migration of Africans, the plantation economy's reliance on slave labor, and the oppression and denial of rights to enslaved people. Abolitionist movements opposed slavery and racial ideology, and the American Civil War from 1861-1865 ultimately led to the end of slavery and new laws protecting civil rights in 1865.
