Final answer:
In 1906, the Transvaal government enacted a law requiring Indians to obtain special permits to travel as part of the early discriminatory policies in South Africa.
Step-by-step explanation:
In 1906, the Transvaal government passed a law that ordered Indians to obtain special permits to travel. This was a part of the discriminatory policies that later evolved into the full-fledged system of apartheid. These measures were designed to control and exploit nonwhite labor and curtail the rights and freedoms of the nonwhite population. The British, who had taken control of South Africa, implemented policies that increasingly disenfranchised the majority population of African descent, and this 1906 law was an early step in the process that would lead to systemic racial segregation.
