From 1948 a system of institutionalised racial segregation (apartheid) was introduced in South Africa. Although a new constitution was adopted in 1961, basic human rights were violated, what were the changes wrought to the South African legal landscape under apartheid?

I need help understanding:

• the primary nature of the laws promulgated during apartheid.
• Examples of legislation passed and enforced during this period.
• A discussion of the impact of these primary laws and how they gave form and effect to apartheid ideology.
