The "Sip-In" was a pivotal protest in LGBTQIA+ history that occurred in 1966 at Julius' Bar in New York City. Inspired by the civil rights sit-ins, members of the Mattachine Society, an early gay rights organization, organized the sip-in to challenge the New York State Liquor Authority's regulation that prohibited bars from serving alcohol to homosexuals. The activists openly declared their homosexuality and demanded to be served, aiming to provoke a refusal based on their sexual orientation, thereby exposing the discriminatory practices. The event successfully attracted media attention and highlighted the prejudicial policies, leading to legal changes that made it illegal to deny service based solely on sexual orientation. This protest marked an important moment in the fight for LGBTQIA+ rights and visibility.
