Martin Luther King Jr. was a pivotal figure in the Civil Rights Movement in the United States. He was a Baptist minister and activist who became the face of the nonviolent struggle for racial equality. King played a crucial role in organizing and leading numerous protests and marches, including the Montgomery Bus Boycott in 1955 and the March on Washington for Jobs and Freedom in 1963.

One of King's most famous speeches, "I Have a Dream," was delivered during the March on Washington, where he called for an end to racism and discrimination in the United States. King was awarded the Nobel Peace Prize in 1964 for his efforts in combating racial inequality through nonviolent civil disobedience.

Tragically, Martin Luther King Jr. was assassinated in 1968 in Memphis, Tennessee. His legacy continues to inspire generations of activists and leaders in the fight for social justice and racial equality. Martin Luther King Jr. Day is celebrated annually in the United States to honor his contributions to the civil rights movement.
