Two-hundred-and-fifty-six transgender people have been murdered around the world in 2012.

According to the Trans Murder Monitoring project, 256 transgender people have been murdered in the past 12 months, a 20 percent increase from the previous year. (A video remembering some of the victims is embedded on this page. Visit our video library for more videos.)

Tuesday's Transgender Day of Remembrance (TDoR) sets out to remember those lost to senseless violence and to raise public awareness around increasing rates of violence facing transgender people.

Vigils in cities across the globe will honor the memory of those lost. A listing of world-wide events can be found at Transgender.org.

Another resource released by GLAAD to coincide with today's events is a timeline illustrating transgender milestones since 1952.

“With anti-transgender violence on the rise, we remember our colleagues, friends and family whose lives were taken simply because of who they are,” GLAAD President Herndon Graddick said in a statement. “We must stand together to end the violence, working every day to spread awareness and acceptance of transgender people.”

TDoR founder Gwendolyn Ann Smith added: “The Transgender Day of Remembrance seeks to highlight the losses we face due to anti-transgender bigotry and violence. 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.”

The first Transgender Day of Remembrance was held in 1999 to memorialize the murder of Rita Hester, a transgender African-American woman whose 1998 murder remains unsolved.
