Key moment: The Christopher Street Liberation Day March in New York City on June 28, 1970, marked the first anniversary of the Stonewall Uprising clashes between police and LGBTQ people and eventually led to the hundreds of Pride parades held annually across the country.
Historical significance: The 1969 raid at New York’s Stonewall Inn, a club for LGBTQ+ people, marked a turning point in the gay rights movement. Police regularly raided such institutions, but this time patrons pushed back. The uprising went on for six days. (Video screen grab courtesy Library of Congress)
