US athletes Tommie Smith and John Carlos caused a sensation when they raised their black-gloved fists in protest, the salute of the Black Power political organisation, on the podium at the Mexico City Olympics after the 200-meter sprint.
They’d already removed their shoes in a protest against poverty and they also wore beads against lynching. Smith and Carlos were later ordered to leave the stadium and were expelled from the American track team. Their actions came amid the context of the Vietnam War and the assassination of Martin Luther King Jr. but remains one of the most powerful images of protest ever. (On this day)
