Soon after, the King Center looked for support from the corporate community and the general public. The success of this strategy was cemented when musician Stevie Wonder released the single ‘Happy Birthday’ to popularize the campaign in 1980 and hosted the Rally for Peace Press Conference in 1981. Six million signatures were collected for a petition for Congress to pass the law and is considered the largest petition in favor of an issue in U.S. history.
President Reagan originally opposed the holiday, citing cost concerns. But on November 2, 1983, Reagan signed a bill, proposed by Representative Katie Hall, to create a federal holiday honoring King. The bill had passed the Senate by a count of 78 to 22, and the House of Representatives by 338 to 90. The holiday was observed for the first time on January 20, 1986. It’s observed on the third Monday of January rather than directly on Martin Luther King, Jr.’s birthday because it follows the guidelines of the Uniform Monday Holiday Act.
