What happened on October 16, 1968, in Mexico City's Olympic stadium will always be remembered as one of the most controversial events in the history of the Games.
On the podium for the 200m stood two black Americans, Tommie Smith on the highest step and John Carlos two steps below.
Wearing black socks and black berets, they stood beside the silver medal-winner, Australian Peter Norman, who also sported a badge on his chest in support of their cause - the American civil rights movement.
As "The Star-Spangled Banner" began to play, Smith and Carlos lowered their heads and raised black-gloved fists to the sky - the right for Smith, the left for Carlos, in accordance with the salute of the Black Panthers activist group.
