Martin Luther King Jr. addressed numerous challenges in his activism, including racial segregation, economic inequality, and the fight for voting rights. He advocated for nonviolent resistance as a means to achieve civil rights, drawing inspiration from Mahatma Gandhi. King faced fierce opposition, legal barriers, and personal risk, yet his ability to articulate the injustices faced by African Americans mobilized widespread support. His leadership in pivotal moments, such as the Montgomery Bus Boycott and the March on Washington, emphasized the urgent need for change. King's vision of equality and justice continues to resonate today.
