The Population Registration Act of 1950 required that each inhabitant of South Africa be classified and registered in accordance with their racial characteristics as part of the system of apartheid. Social rights, political rights, educational opportunities, and economic status were largely determined by the group to which an individual belonged. There were three basic racial classifications under the law: Black, White and Coloured (mixed). Indians (that is, South Asians from the former British India, and their descendants) were later added as a separate classification as they were seen as having "no historical right to the country".
