Cesar Chavez co-founded the National Farm Workers Association (later the UFW) and led strikes and boycotts to secure better pay and safer working conditions for migrant farm workers. Martin Luther King Jr. focused primarily on African American civil rights, while Lyndon B. Johnson signed major civil rights legislation as president.

Delivered during the March on Washington in 1963, the "I Have a Dream" speech is one of the most famous speeches in American history, calling for an end to racism. "By Any Means Necessary" is a phrase famously associated with Malcolm X, not Martin Luther King Jr.

The "I Have a Dream" speech was delivered at the Lincoln Memorial during the March on Washington for Jobs and Freedom in 1963. While Selma and Montgomery were also sites of famous civil rights marches, they were not the location of this specific speech.

Jackie Robinson broke the color barrier in Major League Baseball when he started at first base for the Brooklyn Dodgers.
