“As you honor my father today, please remember and honor my mother, as well. She was the architect of the King Legacy and founder of @TheKingCenter, which she founded two months after Daddy died. Without #CorettaScottKing , activist and civil right leader, there would be no #MLKDay . #MLK50Forward #MLK ” Berenice King, daughter of Coretta Scott King & Martin Luther King. Coretta Scott King led a sanitation workers' march in Memphis only four days after her husband's assassination. Moving on from there, King carried on Martin's legacy — and then expanded it beyond anything he had ever had the chance to express. She was the one who sought to make his birthday a national holiday. She finally succeeded when Ronald Reagan signed legislation which established Martin Luther King, Jr. Day. She later broadened her scope of activism to include both opposition to apartheid and advocacy for LGBT rights.
