Americans United for Separation of Church and State

Americans United for Separation of Church and State is a nonpartisan educational and advocacy organization devoted to defending church-state separation and protecting religious freedom for people of all faiths and none. It pursues this mission through litigation, lobbying, grassroots advocacy, education, and public engagement, seeking to prevent religion from dictating public policy, government from controlling belief or worship, and religious beliefs from being used to justify discrimination. Founded in 1947, it works nationally for freedom and equality.
