Life in Johannesburg was going well for Nelson at first, until he started noticing how badly colored people were treated by white people.
Why are we treated differently than white people?
Eventually he became the lawyer but started having more problems later in life. He couldn't understand why white people had more freedom and privileges than colored people. Colored people were forced into restricted living areas, their homes were poor and cramped, lacking electricity, plumbing and heat. One of the worst things is that they had to carry a passbook at all times. The practices were called Apartheid, and Nelson wanted to end it.
Later, Nelson and his wife had three children and began taking meetings where people would discuss why they should change racist laws. Nelson wanted to do more than this so he started organizing protest marches, boycotts, and strikes. Nelson started realizing the problem with the passbooks began to escalate and a lot more people were getting arrested. Nelson had to do something about it so he told people to leave their passbooks at home and offer themselves for arrest. 15,000 people showed up without their passbooks right in front of a police station but they opened fire and killed 69 people and injured 200 more.
Nelson publicly burned his passbook to show support and after people heard about him he started getting arrested more and more each time getting released but one time he got accused of organizing a sabotage and got sentenced to prison for life.
The prison Nelson got sent to was so cramped and small that he could barely walk anywhere. He started to miss his wife and children and could only have one visitor every six months. Life in prison was tough, he was forced to dig hours a day and eventually people wanted his release from prison.
After people started demanded Nelsons release the felt they had no choice but to set him free. From there on all people were equal and in 1994 Nelson Mandela became president.
