Stonewall Riots

The Stonewall riots (also referred to as the Stonewall uprising or the Stonewall rebellion) were a series of spontaneous, violent demonstrations by members of the gay (LGBT) community against a police raid that took place in the early morning hours of June 28, 1969, at the Stonewall Inn, located in the Greenwich Village neighborhood of Manhattan, New York City. They are widely considered to constitute the single most important event leading to the gay liberation movement and the modern fight for LGBT rights in the United States.

Gay Americans in the 1950s and 1960s faced an anti-gay legal system. Early homophile groups in the U.S. sought to prove that gay people could be assimilated into society, and they favored non-confrontational education for homosexuals and heterosexuals alike. The last years of the 1960s, however, were very contentious, as many social/political movements were active, including the African American Civil Rights Movement, the counterculture of the 1960s, and the anti-Vietnam War movement. These influences, along with the liberal environment of Greenwich Village, served as catalysts for the Stonewall riots.

Very few establishments welcomed openly gay people in the 1950s and 1960s. Those that did were often bars, although bar owners and managers were rarely gay. At the time, the Stonewall Inn was owned by the Mafia. It catered to an assortment of patrons and was known to be popular among the poorest and most marginalized people in the gay community: drag queens, transgender people, effeminate young men, butch lesbians, male prostitutes, and homeless youth. Police raids on gay bars were routine in the 1960s, but officers quickly lost control of the situation at the Stonewall Inn. They attracted a crowd that was incited to riot. Tensions between New York City police and gay residents of Greenwich Village erupted into more protests the next evening, and again several nights later. Within weeks, Village residents quickly organized into activist groups to concentrate efforts on establishing places for gays and lesbians to be open about their sexual orientation without fear of being arrested.
