Brooklyn is home to a large and growing number of same-sex couples. Same-sex marriages in New York were legalized on June 24, 2011, and were authorized to take place beginning 30 days thereafter. The Park Slope neighborhood spearheaded the popularity of Brooklyn among lesbians, and Prospect Heights has an LGBT residential presence. Numerous neighborhoods have since become home to LGBT communities. Brooklyn Liberation March, the largest transgender-rights demonstration in LGBTQ history, took place on June 14, 2020, stretching from Grand Army Plaza to Fort Greene, focused on supporting Black transgender lives, drawing an estimated 15,000 to 20,000 participants.
