There is an extensive body of scholarly works on religion and politics and church–state relationships in American history. A variety of perspectives, disciplines, and emphases has enriched this literature. The following is a bibliography of selected works on the history of religion and religious liberty in America from colonial times to the mid–nineteenth century and on the social and intellectual forces that shaped political culture and church–state relations in the early Republic. Emphasis has been placed on the ample scholarship that examines the framing of the First Amendment religion provisions and the contributions of Thomas Jefferson to a distinctive American approach to church–state relations. Also included in this bibliography are works on Jefferson's religious views and literature on the “wall of separation.” For a comprehensive bibliography of works on church and state in the colonial and early national periods, see John F. Wilson, ed., Church and State in America: A Bibliographical Guide; The Colonial and Early National Periods(Westport, Conn.: Greenwood Press, 1986).
