Tommie Smith and John Carlos made history at the Olympics in 1968.
As the pair accepted the gold and bronze medals in the 200m, they silently raised a gloved hand as the American National Anthem played during the ceremony.
Dressed in black socks and no shoes with Smith adorned in a black scarf, this was more than a victory for a game. It was a silent symbol, a protest in opposition of continued discrimination against black people in the country.
While they were booed by many in the crowd, Smith and Carlos knew who would understand.
