Martin Luther King Jr.’s birth name was Michael.
Martin Luther King Jr. was born in Atlanta, Ga. on Jan. 15, 1929 (and that’s why the holiday is observed on the third Monday in January each year). However, that was not his name when he was born — his parents, Michael King and Alberta King, named him Michael King Jr. after his father.
In the 1930s, as Martin King Sr.’s career as a minister grew, he chose to change his name to Martin Luther King Sr., choosing to honor Martin Luther, the famous German priest for whom Lutheranism was named. As reported by Biography, soon after, Michael Jr. decided to follow in his father’s footsteps, and become Martin Luther King Jr.
