1968 Olympics Black Power salute
During their medal ceremony in the Olympic Stadium in Mexico City on October 16, 1968, two African-American athletes, Tommie Smith and John Carlos, each raised a black-gloved fist during the playing of the US national anthem, "The Star-Spangled Banner". While on the podium, Smith and Carlos, who had won gold and bronze medals respectively in the 200-meter running event of the 1968 Summer Olympics, turned to face the US flag and then kept their hands raised until the anthem had finished. In addition, Smith, Carlos, and Australian silver medalist Peter Norman all wore human-rights badges on their jackets.
