There has always been an intricate relationship between religion and politics. This encyclopedia provides a comprehensive overview of the interrelation of religion and politics from colonial days to the present.

Can a judge display the Ten Commandments outside of the courthouse? Can a town set up a nativity scene on the village green during Christmas? Should U.S. currency bear the "In God We Trust" motto? Should public school students be allowed to form bible study groups? Controversies about the separation of church and state, the proper use of religious imagery in public space, and the role of religious beliefs in public education are constantly debated. This work offers insights into contemporary controversies regarding the uneasy intersections of religion and politics in America.

Organized alphabetically, the entries place each topic in its proper historical context to help readers fully grasp how religious beliefs have always existed side by side-and often clashed with-political ideals in the United States from the time of the colonies. The information is presented in an unbiased manner that favors no particular religious background or political inclination. This work shows that politics and religion have always had an impact on one another and have done so in many ways that will likely surprise modern students.
