The modern transgender rights movement has its roots in the mid-20th century, with the work of pioneers like Christine Jorgensen, a trans woman who gained international attention in 1952 for her transition. The 1960s and 1970s saw the emergence of LGBTQ activism, including the Stonewall riots in 1969, which marked a turning point in the fight for LGBTQ rights. The 1980s and 1990s witnessed the rise of transgender activism, with organizations like the Tri-Essence (1980) and the National Center for Transgender Equality (2003).
