The 1960s was a time of social upheaval in the West, and the sexual revolution and counterculture influenced changes in the homosexual subculture, which in the U.S. included bookshops, publicly sold newspapers and magazines, and a community center. It was during this time that Los Angeles saw its first big gay movement. In 1967, the night of New Years, several plainclothes police officers infiltrated the Black Cat Tavern. After arresting several patrons for kissing to celebrate the occasion, the officers began beating several patrons and ultimately arrested 16 more bar attendees including three bartenders. This created a riot in the immediate area, ultimately bringing about a more civil demonstration of over 200 attendees several days later protesting the raids. The protest was met by squadrons of armed policemen. It was from this event that the publication "The Advocate" and organization Metropolitan Community Church (led by Pastor Troy Perry) were born.
