Lesbian, gay, bisexual, transgender and queer (LGBTQ) movements are social movements that advocate for the inclusion, recognition, and rights of LGBTQ people and other gender and sexual minorities.
While there is no overarching organization representing all LGBTQ people, numerous advocacy groups, grassroots networks, and community-based organizations work to advance related causes. The earliest known LGBTQ rights organization was the Scientific-Humanitarian Committee, founded in Berlin in 1897.
