What did Martin Luther King Jr. advocate for?

Martin Luther King Jr. greatly advocated for civil rights and equality, primarily focusing on ending racial segregation and discrimination against African Americans. His leadership during the Civil Rights Movement was centered on the belief that all individuals, regardless of race, deserve equal rights and opportunities. He is best known for his emphasis on nonviolent protest and civil disobedience as methods to challenge unjust laws and practices.

King's famous "I Have a Dream" speech encapsulates his vision for a society where people are judged by their character instead of the color of their skin. By promoting the message of love, peace, and equality, he aimed to inspire a collective effort to dismantle systemic racism and promote justice for all marginalized groups. His work led to significant legal advancements, such as the Civil Rights Act of 1964 and the Voting Rights Act of 1965, which were crucial in the pursuit of equality in the United States.

The other options, while important in their own right, do not encompass the primary focus and legacy of King’s advocacy. His substantial contributions specifically addressed civil rights and equality, making that the most accurate representation of his life's work.
