Jackie Robinson broke the color line in Major League Baseball when he debuted with the Brooklyn Dodgers on April 15, 1947. This decision would not only integrate baseball, but would help the country work to achieve equal rights for all. Civil Rights leader, Martin Luther King, Jr., once commented to baseball pitcher Don Newcombe, “Don, you and Jackie will never know how easy you made my job, through what you went through on the baseball field.”
Before becoming famous, Lt. Jack R. Robinson was court-martialed at Camp Hood, Texas, because he refused to move to the back of the bus after being told to do so by a bus driver and disobeying an order from a superior officer. Robinson was acquitted of all charges and received an honorable discharge, but this was not the only experience he would have in fighting discrimination.
After retiring from baseball, Robinson turned much of his attention to civil rights issues. He wrote to several Presidents about the cause, and even attended the March on Washington.
Many of these milestone events from Robinson’s life are documented in primary sources from the National Archives.
