The powerful image saw Hamilton, who remains the only current black driver in Formula One and the only black world champion in the sport’s history, raise his right fist after the national anthems to show his support for the anti-racism movement that has been in the spotlight over the last two months.
The gesture mirrored the famous sight of the 1968 Olympics, when African-American athletes Tommie Smith and John Carlos wore black gloves and raised their fists during the United States national anthem in support of the civil rights movement.
Speaking before the salute, Hamilton expressed his delight at recovering after a tricky opening weekend to take his first victory of the season and get his attempt to equal Michael Schumacher’s tally of seven world titles up and running.
"It is great to be back up here and driving with this kind of performance," said Hamilton after the race. "It was about keeping it together and bringing it home.
"I am so grateful to be back in first place. It feels like a long time since I won at the final race of last season. This is a great step forward."
Hamilton’s gesture came after four drivers elected to stand while the rest of the grid took a knee, with 11 others joining Hamilton in kneeling before the Austrian national anthem ahead of the race.
Six drivers chose to remain standing before last weekend’s season-opening Austrian Grand Prix, with the other 14 drivers all taking a knee to show their support in the fight against racism.
Charles Leclerc and Max Verstappen were among those who chose not to take a knee last weekend, with Alfa Romeo pair Kimi Raikkonen and Antonio Giovinazzi, McLaren’s Carlos Sainz and Alpha Tauri’s Daniil Kvyat the others who remained on their feet.
Verstappen, Leclerc, Raikkonen and Kvyat again chose to remain on their feet before the Styrian Grand Prix, while Hamilton took a knee alongside 11 other drivers on the grid.
However, the stance was somewhat hampered by the fact that not all drivers made it to the grid in time for the anti-racism message, with a number seen running towards the finish line while others had already begun to kneel. Both Sergio Perez and Giovinazzi could be seen running behind and missed the ceremony.
All 20 drivers once again wore T-shirts that had the message ‘END RACISM’ printed on the front, though as he did last weekend Hamilton reversed his shirt so that the message was on the back and instead had ‘Black Lives Matter’ on the front of his.
The stance came before the Austrian national anthem, which saw all drivers return to their feet to honour it before returning to their cars ahead of the race.
