Early in the morning on June 28, 1969, New York police raided the Stonewall Inn at 53 Christopher Street, the city’s most popular gay bar. The police had raided Stonewall frequently since its opening two years before, but the local precinct usually tipped off the management and arrived in the early evening. This time they came unannounced, during peak hours. They swept through the bar, checking I.D.s and arresting anyone wearing attire that was not “appropriate to one’s gender,” carrying out the law of the time. Eyewitness accounts differ on what turned the unruly scene explosive. Whatever the inciting event, patrons and a growing crowd on the street began throwing coins, bottles, and bricks at the police, who were forced to retreat into the bar and call in the riot squad.
