The principal religious humanist organization is the American Humanist Association (AHA), founded in 1941. (While AHA’s aims extend beyond religious humanism and include naturalistic humanism, it serves as “home organization” for a great many religious humanists.) Other religious humanist organizations include the American Ethical Union, the North American Committee for Humanism, the International Institute for Secular Humanistic Judaism, the former Friends of Religious Humanism, now calling itself “HUUmanists,” and the Humanist Society of Friends. The latter two organizations are now included within the AHA. 

Though the term secular humanism appeared prior to 1961, no organization existed specifically to advocate it until Paul Kurtz and others formed the Council for Democratic and Secular Humanism (CODESH) in 1980. The name expressed opposition to totalitarian nontheisms such as those in the communist world. <...> Free Inquiry was launched late in 1980, publishing the full text of the Declaration in its inaugural issue. In 1996, CODESH shortened its name to the Council for Secular Humanism, the fall of communism having rendered the modifier “democratic” unnecessary.
