Carl McIntire (1906-2002), the fiery Fundamentalist minister played a key role in the rise of the modern Conservative movement that emerged following the Second World War. From his home base in the Philadelphia suburb of Collingswood, NJ, McIntire led a movement he called the Twentieth Century Reformation that was a fusion of Christian Fundamentalism and Conservative politics. Through this, and his organizations that sought to mobilize Fundamentalism, McIntire presented a baptized Conservatism from the Cold War through the culture wars of the 1960s with his last public stands taking place in support of the Vietnam War, and fight against the Sexual Revolution. In the pages that follow, I will argue that political Fundamentalism played an important role in the rise of Conservatism between 1943 and 1973 – much earlier than scholars have generally thought – as well as in the subsequent public reconciliation between Evangelicals and Fundamentalists in the conservative movement associated with Jerry Falwell and Ronald Reagan in the final years of the Carter Administration.
