Today, the US observes Martin Luther King, Jr. Day, a Federal holiday.
Dr. King was world-renowned for his work for the civil rights movement in America, leading to the Civil Rights Act of 1968.
Martin Luther King, Jr. was born Michael King, Jr. in 1924 in Atlanta, Georgia. His name was changed 10 years later, after his family visited Eisleben, Germany, the birthplace of Martin Luther, who founded Protestantism. His father, Michael King Sr., changed both his name and his son's name to Martin Luther in honor of him.
