Religion is resurgent across the globe. In many countries religion is a powerful source of political mobilization, and in some a potent social cleavage. In some religion reinforces the state, in others it provides the space for resistance. This book contains a series of detailed studies examining religion and politics in specific countries or regions. The cases include countries with one dominant religious tradition, and others with two or more competing traditions. They include Catholicism, Protestantism, Islam, Hinduism, Shinto and Buddhism. They include states where religion and politics are closely linked, and others with at least a low wall of separation between church and state. The cases are organized by the type of religious marketplace, but allow many other comparisons as well. We develop some generalizations from the cases, and hope that they will be a fertile source of theorizing for others.
