Transgender is an umbrella term applied to people and behaviors which diverge from those of normative two-gender roles (male and female), usually assigned at birth. Transgender refers to the state of one's gender identity (male, female, or various other identities) and not to sexual identities, a common misunderstanding.
Transgender identities and expression have been a fixture of culture since antiquity. One example is South Asian, where Hijras (pictured at right) are considered members of a third gender.
Transsexual people are those who establish a permanent identity with the gender opposite to the biological sex at which they were assigned at birth. As most legal jurisdictions have at least some recognition of the two traditional genders at the exclusion of other categories, this raises many legal issues and aspects of transsexualism. Most of these issues tend to be located in what is generally considered family law, especially the issue of marriage, but also things such as the ability of a transgendered person to benefit from a partner's insurance or social security.
