The San Francisco Trans March, the City's largest transgender Pride event, will be celebrating the 45th anniversary of a riot that helped pave the way for the modern LGBT rights movement, organizers said.
In August 1966, a group of transgender people rose up in anger against harassment at the Gene Compton's Cafeteria in the City's Tenderloin neighborhood, organizers said.
The riot was the subject of the 2005 documentary, "Screaming Queens."
One of the "screaming queens" who participated in the riot, Felicia Flames, will deliver the keynote address at Friday's celebration, organizers said.
Revelers will also be treated to performances by artists, including DJ Stephanie Luz, The Introverts, and Josie and the Pussycats.
The celebration will be held at Mission Dolores Park at 3:30 p.m. The march to the Civic Center will follow at 6:30 p.m.
