Through powerful speeches, including the famous "I Have a Dream", King inspired generations to fight against systemic racism and segregation. His leadership during pivotal events, such as the Montgomery Bus Boycott and the March on Washington, played a critical role in advancing civil rights legislation and raising awareness of social injustices.
