What racism does Gandhi experience while in South Africa?

While he was travelling by train to Pretoria, Gandhi, despite carrying first class ticket, was thrown out of the train by the authorities because a white man complained of an Indian sharing the space with him.
2. As a response, Gandhi formed the Natal Indian Congress in 1894. This organisation led non-violent protests against the oppressive treatment of the white people towards the native Africans and Indians.
3. In 1896, he came to India for a short time and gathered 800 Indians to serve along with him in South Africa. They were welcomed by an irate mob and Gandhi was injured in the attack.
4. During the outbreak of the Boer War in 1899, Gandhi gathered around 1,100 Indians and organised the Indian Ambulance Corps for the British but the ethnic discrimination and torture continued on Indians.
