===Theology===
{{main|Postmillennialism}}
[[Postmillennialist]] theology dominated American Protestantism in the first half of the 19th century. Postmillennialists believed that Christ will return to earth after the "[[millennialism|Millennium]]", which could entail either a literal 1,000 years or a figurative "long period" of peace and happiness. Christians thus had a duty to purify society in preparation for that return. This duty extended beyond American borders to include [[Christian Restorationism]]. [[George M. Fredrickson|George Fredrickson]] argues that Postmillennial theology "was an impetus to the promotion of Progressive reforms, as historians have frequently pointed out."<ref name="Fredrickson">George M.

By the late 1840s, however, the great day had receded to the distant future, and postmillennialism became a more passive religious dimension of the wider [[middle-class]] pursuit of reform and progress.<ref name="Fredrickson"/>
