The Women's Declaration International (WDI), formerly the Women's Human Rights Campaign (WHRC), is an international advocacy organisation founded in the United Kingdom. WDI has published a Declaration on Women's Sex-Based Rights, and has developed model legislation to restrict transgender rights that has been used in state legislatures in the United States.

TERF is an acronym for trans-exclusionary radical feminist. First recorded in 2008, the term TERF was originally used to distinguish transgender-inclusive feminists from a group of radical feminists who reject the position that trans women are women, reject the inclusion of trans women in women's spaces, and oppose transgender rights legislation. Trans-inclusive feminists assert that these ideas and positions are transphobic and discriminatory towards transgender people. The use of the term TERF has since broadened to include reference to people with trans-exclusionary views who are not necessarily involved with radical feminism. In the 2020s, the term "trans-exclusionary radical feminism" is used synonymously with or overlaps with "gender-critical feminism".
