This June marks the 55th anniversary of the first LGBTQ+ Pride march held in the United States.

LGBTQ+ Pride Month, also known simply as Pride Month, is held each June, an observation of queer culture through celebration and protest. Countless communities host Pride marches, demonstrations and parties to honor queer joy, but Pride Month’s roots are tied to a darker time.

The first LGBTQ+ Pride march was held in June 1970, just one year after New York City Police officers invaded the Stonewall Inn in Greenwich Village, which resulted in a six-day riot in the neighborhood. Though raids and concurring protests and marches had been ongoing for decades before, the Stonewall Riots proved to be a quintessential moment for the LGBTQ+ community in the U.S.

Here’s a closer look at Pride Month’s origins and how 10 major U.S. cities are celebrating this summer.
