Church-state relations have always been important but the need for an historical re-evaluation has been heightened by recent developments in the relations between governments and religious bodies. Drawing on a wide range of historical case-studies this book focuses particularly on the way in which the traditional European Old World fusion of church and state was reshaped in the New World of European settler colonies of the United States, Australia and New Zealand. Its analysis illuminates both the historical dynamics of such changes and the way in which such developments continue to influence the conduct of church-state relations in both the Old and the New Worlds.
