The American LGBTQ rights movement has historical origins tracing back to the early 20th century, notably with the establishment of the Mattachine Society in 1950 and the Daughters of Bilitis in 1955, which sought to advocate for gay rights and create community among LGBTQ individuals. However, significant milestones included the Stonewall Riots in 1969, which served as a catalyst for activism and visibility. The movement gained momentum through various social and political struggles, advocating for decriminalization, anti-discrimination laws, and marriage equality, culminating in a broader push for civil rights that remains relevant today.
