We're starting with a look back at an event from April 4th, 1968, an event that changed a nation.
Fifty years ago today, Dr. Martin Luther King Jr. was assassinated in Memphis Tennessee. He was a Baptist minister and an activist. He was a writer and a gifted speaker.
He delivered his most famous speech during the march on Washington in 1963. He was named "Time Magazine's" Man of the Year in 1963. He received a Nobel Peace Prize in 1964.
And today, Dr. King is remembered as being one of the most renowned civil rights leaders in history.
One of his main goals was to use what he called non-violent direct action, peaceful protests like marches and sit-ins to promote equal treatment for African-Americans in the U.S.
Dr. King was no stranger to controversy. He was arrested and jailed in solitary confinement for leading a march in Birmingham in Alabama. He spoke out publicly against U.S. involvement in the Vietnam War, which angered many people in the late 1960s. Some of his activism on behalf of America's poor failed to get the results that he and his supporters hoped for.
Not long before his assassination, Dr. King said in a sermon, quote: Living every day under the threat of death, I feel discouraged every now and then and feel my work is in vain, but then the Holy Spirit revives my soul again.
A half century later, it's clear Dr. King's work was not in vain.

金博士也是一个争议人物 。他曾因为领导阿拉巴马州伯明翰市的游行活动而被捕并被单独拘禁 。他公开反对美国参与越南战争，这在上世纪60年代末期激怒了许多人 。他发起的一些代表美国穷人的行动并没有取得他和支持者们最后所希望的结果 。
