Transgender Day of Remembrance, which is held Nov. 20 each year, commemorates transgender individuals who died as a result of discrimination and victimization. The day was first celebrated to remember Rita Hester, a transgender African-American woman who was murdered in November 1998.

The LGBT community and its allies gather each year to honor the memories of those lost to anti-transgender hate crimes, as well as to educate others about gender variant individuals. Many cities hold events to provide an opportunity to raise awareness about the high rates of violence faced by transgender people and the persistent prejudice they face.

"The Transgender Day of Remembrance seeks to highlight the losses we face due to anti-transgender bigotry and violence," Gwendolyn Ann Smith, an advocate who founded the day, said. "I am no stranger to the need to fight for our rights, and the right to simply exist is first and foremost. With so many seeking to erase transgender people — sometimes in the most brutal ways possible — it is vitally important that those we lose are remembered, and that we continue to fight for justice.”
