Following Rosa Parks' arrest in 1955 for refusing to move to the back of a bus in Montgomery, he organized a year-long bus boycott. The "Montgomery Movement" led to the integration of the city's buses and launched a non-violent protest movement that spread across the United States. King, along with Fred Shuttleworth and others led the Birmingham Campaign to desegregate Birmingham, Alabama. The brutality displayed towards the Campaign's demonstrators and King's "Letter from a Birmingham Jail", written while he was incarcerated, brought national and international attention to the civil rights movement. Ultimately, King was arrested 30 times for his participation in civil rights activities. In 1963, he was one of the organizers for the March on Washington and the following year he received the Nobel Peace Prize. In 1965, King helped to organize the Selma to Montgomery marches. He worked tirelessly to assure the passage of the Civil Rights Act of 1964 and was in attendance when President Johnson signed both that Act and the Voting Rights Act of 1965 into law. In the final years of his life, he expanded his focus to include poverty and the Vietnam War.
In 1968, Martin Luther King was assassinated while in Memphis, Tennessee, to help striking sanitation workers. His legacy lives on and his writings and speeches, including "I Have a Dream", from the March on Washington and "I've Been to the Mountaintop," given just hours before his death, continue to inspire new generations.
