Transgender is an umbrella term which is applied to a variety of people and gender-expressive behaviors which diverge from the normative two-gender roles (male and female) assigned at birth. Transgender refers to both the state of one's gender identity (male, female, or various other identities), and to outward gender expression. Gender identity is a separate concept from sexual orientation, and transgender people have varying sexual identities.
Transgender identities and expression have been a fixture of various cultures, including non-western cultures, from ancient times.
