What was the motive idea behind the passing of apartheid law in sa?

The primary motive behind the passing of apartheid laws in South Africa was to institutionalize racial segregation and maintain white supremacy. The National Party, which came to power in 1948, aimed to enforce strict racial divisions in every aspect of life, including education, housing, and employment, to ensure that the white minority retained political and economic control over the majority black population. These laws were justified by a belief in racial superiority and were intended to prevent any challenge to the existing social order.
