On June 12, 1963 a bullet killed Medgar Evers in front of his family. His wife, Myrlie, would say at his funeral "you can kill a man, but you can't kill an idea".
On Wednesday night a gala commemoration in Jackson was a testament to that.
Put on by the Medgar and Myrlie Evers Institute, hundred of people celebrated the Evers' Mission. He was killed while working as the field secretary for the Mississippi NAACP.
Family members and civil rights activists with national name recognition were in attendance.
"Each assassination called this nation to its conscience to say 'Can we do better than we were yesterday because it was the yesterday before today that made the assassination possible'," Benjamin Todd Jealous, President and CEO of the NAACP said.
Blues Legend B. B. King gave a special performance after receiving the Inaugural Evers Justice Award.
The Reverend Jessie Jackson was also in attendance for the commemoration.
