Mandela was South Africa's first black president. He started a peaceful, non-violent campaign against the racist policies of the South African government. Mandela eventually won the Nobel Peace Prize and was known for being a source of inspiration when acting on civil rights worldwide. Mandela was known for always wanting peace, and always working his hardest to get it.
MLK liked that Gandhi was non-violent and that he worked to get rights for his people. MLK was inspired by Gandhi and he wanted to do almost exactly what Gandhi had done, he wanted rights for black people. MLK saw that Gandhi was a humble person and that he would never want to hurt anyone. He saw that Gandhi had helped so many great things happen, and that he could do that too. MLK said he and his people must continue to protest with non-violence. He said "Non-violent protesting is one of the most powerful methods ever." He says that the road to freedom is long, but that they will eventually get there.
Gandhi inspired many people, and many people looked up to him and hoped that they could be like him. He was a humble person and he did things like visiting the poor and things that benefitted other people. He was with the Indians and they were ruled by the British. They could only buy British products, food, etc. The British even taxed them on buying salt! So, Gandhi decided that that needed to end. He started a disobedience campaign in 1906 that would last the next 8 years. In those 8 years (he was an Indian), him and his people were happy to go to jail and do things the British didn't want them to do. For example, like I mentioned earlier, the British taxed them on salt. So, Gandhi and his followers went to where they got the salt and they got all the salt they wanted. Things like this went on for 7 years. And finally, the British said they were under to much pressure and so the government in South Africa decided to accept a compromise made by Gandhi and General Jan Christian Smuts, which consisted of things like the recognition of Indian marriages and ending the existing poll tax for Indians. A year later, Gandhi went back to India from South Africa and by 1920 he was the most visible figure in the movement for Indian independence.
