The three activist I did where Martin Luther King, Rosa Parks, and Ceasar Chavez. This were all smart activist leaders that gained more rights for a certain group of people. They triggered boycotts, which was a useful technique to being heard. They also triggered marches, usually to government officials to solve political concerns regarding minorities. All this activist had a very strong impact on Civil rights today.
