The Stonewall riots were a series of violent demonstrations by members of the gay community against a police raid that took place in June 28, 1969, at the Stonewall Inn, in the neighborhood of New York City. This event leading to the modern fight for gay and lesbian rights in the United States
Early marches commonly used 'Gay Liberation' and 'Freedom' in their names. Then, with cultural changes and decreased militancy in the 1980s and 1990s, these words became less frequent, and the term 'Gay Pride' became commonly used.
Europe has a pan-European international Pride event, called appropriately Europride.
