Martin Luther King Jr. was a pivotal leader of the African-American Civil Rights Movement. While fighting against the injustice faced by African Americans, he steadfastly adhered to nonviolence. His philosophy was rooted in Christian doctrines, and for operational techniques, he drew inspiration from Mahatma Gandhi's nonviolent resistance. King's first major campaign was the Montgomery Bus Boycott. This movement not only led to the abolition of racial segregation on Montgomery's public transportation system but also established King as a national figure and the most prominent spokesperson of the civil rights movement. He subsequently led many other nonviolent campaigns and delivered numerous inspiring speeches. As the movement grew, King expanded its scope to include the fight for economic justice and equal employment opportunities. One of the most notable campaigns under his leadership was the March on Washington for Jobs and Freedom, where he delivered his iconic "I Have a Dream" speech. During his lifetime, King was arrested 29 times for his activism. He envisioned a world where people would be judged by their character and abilities rather than the color of their skin. Tragically, his life was cut short at the age of 39, when he was assassinated by a white supremacist.
