, who identifies as gay and non-binary and uses "they/them" pronouns offstage , an American philosopher, who published
Gender Trouble in 1990 and publicly came out as non-binary in 2019, is a contemporary figure in the non-binary movement. Non-binary gender, often included within the concept of
third gender, has historical roots that extend well before the modern term was established. For instance, the
Public Universal Friend, who emerged in 1776, was a genderless evangelist who renounced their birth name and gendered pronouns, representing an early instance of non-binary gender expression in America. In 1781, Jens Andersson from Norway, assigned female at birth but identifying as male, faced imprisonment and a trial after marrying a woman. When questioned, Andersson stated, "Hand troer at kunde henhøre til begge Deele" ('He believes he belongs to both parts'), indicating a recognition of his dual gender identity.
Judith Butler's
Gender Trouble, published in 1990, challenged the fixed male/female binary and advocated for a broader understanding of gender as a spectrum, a view Butler has expanded upon since coming out as non-binary in 2019. The term "genderqueer" surfaced in the mid-1990s, notably used by activist
Riki Wilchins in the newsletter
In Your Face in 1995, and later in their 1997 autobiography. Wilchins contributed significantly to the discourse, particularly with the 2002 anthology
GenderQueer: Voices from beyond the Sexual Binary.
Jim Sinclair, an autism-rights activist and a founder of Autism Network International, publicly embraced a gender-neutral identity in 1997, declaring a physical and social neuter status in an introduction to the
Intersex Society of North America. In
Japan, the expression "
X-gender" () has been recognized since the late 1990s, describing a non-binary identity, with notable individuals such as manga artists
Yūki Kamatani and
Yuu Watase identifying as such. In 2012, the Intersex & Genderqueer Recognition Project began advocating for more inclusive gender options on official documents, a milestone realized when
Elisa Rae Shupe became the first person in the U.S. to obtain official documents with a non-binary gender marker.
Alberta legislator
Estefan Cortes-Vargas openly identified as non-binary during a 2015 legislative session, marking a significant moment in political recognition of non-binary identities. On January 20, 2025, immediately after being sworn in for his second term,
President Donald Trump signed an
executive order titled "
Defending Women from Gender Ideology Extremism and Restoring Biological Truth to the Federal Government". This order established that the
U.S. federal government would recognize only two sexes—
male and
female—defined strictly by
biological characteristics at birth. It explicitly rejected the concept of gender identity as a basis for legal recognition for non-binary people. ==Pronouns and titles==
