Washington United for Marriage was a coalition of secular and religious organizations in Washington State involved in lobbying the State Legislature to provide marriage for same-sex couples. The organization was founded in 2011, and formed to secure passage of a bill in the Washington legislature calling for same-sex marriage, and to then defend such a measure should a statewide referendum be launched to challenge it. Members of the coalition include Equal Rights Washington, the Human Rights Campaign, and the American Civil Liberties Union. Within 24 hours of having been publicly launched, the coalition had secured an endorsement for same-sex marriage in Washington from the editorial board of the Seattle Times.
