Why is June celebrated as LGBTQ pride month around the world?

The LGBTQ pride month is celebrated in June to commemorate the anniversary of Stonewall riots at Stonewall Inn in New York, a gathering space for LGBTQ community during the 60s. On June 28, 1969, police raided the inn, leading to the gay liberation movement in the US. 'Mother of Pride' Brenda Howard organised the first pride parade a year later.
