I/ The activists who contributed at the evolution of America

To beginning, there is Malcolm X, he remains a figure in the history of black Americans. This great orator is considered by some to be an ardent defender of the rights and freedoms of the black people in the twentieth century. Indeed, during his life, he switched from being a drug trafficker and a burglar to being the leader of the Black Nationalist movement in the United States. He is considered for certain as a lawyer for equality. A militant leader, Malcolm X supported the black pride and political identity of the African American community. Secondly, there is Martin Luther King, for many years, Martin Luther King had fought against racial segregation. He made himself known in Montgomery by organizing a boycott of the bus company in the city, condemning the segregation in his vehicles. His Civil Rights Movement had finally triumphed by applying the principles of non-violence advocated by Gandhi. Finally, there is Rosa Park; she is an African American woman who became an iconic figure in the struggle against racial segregation in the United States, which earned her the nickname of "Mother of the Civil Rights Movement" from the US Congress. Rosa Parks later fought against racial segregation with Martin Luther King.
