Step-by-step explanation:
When Did Martin Luther King Win the Nobel Peace Prize?
Martin Luther King Jr. was awarded the Nobel Peace Prize in 1964 for his nonviolent struggle against racial segregation and his efforts towards peace and racial equality. His leadership in various civil rights activities, including the Montgomery Bus Boycott and the March on Washington where he delivered his iconic "I Have a Dream" speech, significantly contributed to his nomination and subsequent award of the Nobel Peace Prize. The Civil Rights Movement was incredibly diverse, and although it cannot be attributed to a single individual, Martin Luther King Jr.'s role was undeniably pivotal.
In addition to King's achievements, other notable figures have received the Nobel Peace Prize for their efforts in promoting peace and humanitarian work. For instance, George C. Marshall was awarded the Nobel Peace Prize in 1953 for his plan to restore the economies of Europe after World War II.
