The legal institution of human chattel slavery, comprising the enslavement primarily of Africans and African Americans, was prevalent in the United States from its founding in 1776 until 1865, predominantly in the South. Slavery was found throughout European colonization in the Americas. From 1526, during the early colonial period, it was practiced in what became Britain's colonies, including the Thirteen Colonies that formed the United States. Under the law, children were born into slavery, and an enslaved person was treated as property that could be bought, sold, or given away. Slavery persisted in about half of the U.S. states until its abolition in 1865. Issues involving slavery seeped into every aspect of national politics, economics, and social customs. In the decades after Reconstruction ended in 1877, many of slavery's economic and social functions continued through segregation, sharecropping, and convict leasing. Involuntary servitude as a punishment for crime remains legal.
