During apartheid, people were divided into four racial groups and separated by law. The system was used to deny many basic rights to non-White people, mainly Black people who lived in South Africa. The law allowed white people to be in certain areas. Black people had to carry special passes or have permission to travel outside their designated area, or work in particular areas reserved for Whites. The government separated mixed communities and forcibly moved many black people off their land (From 1960 to 1983 the Bantustan Policy was enforced to forcibly move South African blacks out of the areas designated for 'whites'). Many other laws were made, for example: interracial marriage was outlawed; Black people could not own land in White areas or vote.
