It is common for members of the Church of Jesus Christ of Latter-day Saints to be considered one of the most conservative religious groups in the United States. What is less well understood is as to when the relationship between Mormonism and American conservatism began. While some historians point to the social upheavals in the 1960s and 1970s as the glue that united Mormons and conservatives, the connection began decades earlier during the Great Depression. Leaders of the Mormon Church interpreted Roosevelt’s New Deal as the fulfillment of eschatological prophecy. Envisioning themselves saving America and the Constitution at the world’s end, Mormon authorities established their own welfare program to inspire Latter-day Saints and Americans in general to eschew the New Deal. Anti–New Dealers used the Mormon welfare plan to construct a conservative ideology. Accordingly, Mormons are essential elements in the formation of a political movement that revolutionized the United States.
