In 1968, two American athletes – Tommie Smith and John Carlos – stepped atop an olympic podium following gold and bronze wins in the 200m dash. As their national anthem played, both raised black gloved fists, hanging their heads in silent protest against poor treatment of African Americans in the US. In the weeks and months following, criticism and death threats ensued.
48 years later, NFL players Colin Kaepernick and Eric Reid would take a knee as the national anthem rang out across a football pitch in Santa Clara, California. At first, their gesture went largely under the radar. Then, one year on, president Trump condemned those who choose not to offer their unwavering patriotism.
