The push for a federal Martin Luther King Jr. holiday began almost immediately after Dr. King’s assassination in April 1968, when the late Representative John Conyers introduced the first motion to make King’s birthday a federal holiday. Yet it would take another 11 years for the proposal to reach the floor of the House of Representatives for a vote in 1979. When the bill fell just five votes short of the two-thirds majority needed to pass, it was music that helped galvanize the nation.
