bars, where they were able to congregate openly without being harassed or arrested. In 1966 the New York Mattachine held a "sip-in" at a Greenwich Village bar named Julius, which was frequented by gay men, to illustrate the discrimination homosexuals faced. None of the bars frequented by gay men and lesbians were owned by gay people. Almost all of them were owned and controlled by organized crime, who treated the regulars poorly, watered down the liquor, and overcharged for drinks. However, they also paid off police to prevent frequent raids. Stonewall Inn The Stonewall Inn, located at 51 and 53 Christopher Street, along with several other establishments in the city, was owned by the Genovese crime family. In 1966, three members of the Mafia invested $3,500 to turn the Stonewall Inn into a gay bar, after it had been a restaurant and a nightclub for heterosexuals.

The interior was painted black, making it very dark inside, with pulsing gel lights or black lights. If police were spotted, regular white lights were turned on, signaling that everyone should stop dancing or touching. In the rear of the bar was a smaller room frequented by "queens"; it was one of two bars where effeminate men who wore makeup and teased
