The document discusses Martin Luther King Jr. and his leadership of the American civil rights movement in the 1950s-60s, including Rosa Parks' refusal to give up her bus seat which sparked the Montgomery Bus Boycott, King's advocacy for desegregation that led to the 1963 March on Washington and his Nobel Peace Prize, and his assassination in 1968 which resulted in race riots, as well as how streets are now named after him in many cities.
