Sunday's event is scheduled to take place at 12 p.m. With Sunday's event preparing for takeoff, here's everything there is to know about this year's parade. 'In 2017, we were joined by over 450+ unique marching contingents, representing a vast array of nonprofits, community organizations, corporate partners, small businesses, political candidates and activists! With over 110 floats making the trek down Fifth Avenue, last year's March was one of the largest and most exciting in history.' 'The March is a celebration of our lives and our community,' NYC Pride's website reads. It's now commemorated annually, ultimately becoming an important civil rights movement. The parade served as a launching pad for other cities across the United States to hold their own respective marches. It occurred one year after the 1969 Stonewall Riots, which were multiple violent protests organized by members of the LGBT community after the NYPD raided known gay club Stonewall Inn. The first-ever gay pride parade in American history was held in NYC's Central Park on June 28, 1970. As Pride Month continues, things are slated to get even more exciting with the 2018 New York City (NYC) Pride March aiming to celebrate members of the LGBTQIA+ community Sunday.
