Dr. Martin Luther King Jr. did so many good things for African American people. King leaded a boycott of bus segregation. The move lasts 381 days and ends with the US Supreme Court's decision to prohibit discrimination.
King organized black civil rights campaigns based on the Indian leader Gandhi's philosophy of nonviolence. In 1960 it manages to free black access to libraries, public parks and cafeterias. Leads the March on Washington, which brings together 250,000 people in 1963.
He was killed by a white man.
If he had not been killed, he could have achieved many improvements for African Americans. As a result of his death, the struggle of blacks, not only Americans, but blacks from other countries was inspired to fight for their rights, a new way of fighting for equality was seen.
Perhaps if he had not been murdered there would not have been so many good consequences and a good reaction from black people around the world who see him as an inspiration even after so many years.
