June is Pride Month because of the Stonewall riots.
June is Pride Month, which means that there are celebrations and commemorations happening all over the world. The month-long celebration began in 1999, when it was decided that June would be dedicated to the Stonewall riots. This event took place in 1969, where a police raid on the Stonewall Inn led to a riot that has become an important part of LGBT history. The event has been commemorated with Pride celebrations ever since.
