Moments after Serena Williams won her seventh Wimbledon title, she proudly raised her fist in a black power salute.
It caused a bit of frenzy at the All-England Club in 2016, but Williams' action shouldn't have surprised anyone: She'd already been one of the most vocal supporters of the Black Lives Matter movement. She was one of the first major athletes to decry the failure to indict a white officer in the death of unarmed black teenager Michael Brown in Ferguson, Mo., — while also condemning violence against police.
"What caused me to speak out? Just life," Williams said.
