Pride Month is an annual celebration of the many contributions made by the LGBTQ+ community to history, society and cultures worldwide. In most places, Pride is celebrated throughout June each year in commemoration of its roots in the Stonewall Riots of June 1969, when patrons and supporters of the Stonewall Inn in New York City staged an uprising to resist the police harassment and persecution to which LGBT Americans were commonly subjected. One year later, during the anniversary of the Stonewall Riots, activists in New York City marched through the streets of Manhattan in commemoration of the uprising. In June 2000, President Bill Clinton officially designated June as Gay and Lesbian Pride Month, in recognition of the Stonewall Riots and gay activism throughout the years. A more-inclusive name was chosen in 2009 by President Barack Obama: Lesbian, Gay, Bisexual and Transgender Pride Month.
