Federal Political Systems and Federal Societies
Until these recent studies by Riker, Watts, and Wildavsky appeared, the theory of federalism was embodied largely in the work of K. C. Wheare. Wheare published the first truly pathbreaking book in the comparative study of federalism shortly after World War II. He defined federalism as that system of government in which the federal and regional governments are both coordinate and independent. In applying this definition, he stressed the sharp division in the powers and functions of two coequal sovereignties as a basis for classifying systems of government as federal. Wheare's definition was derived primarily from his analysis of die American Constitution and, in particular, its formally sharp division of powers between national and state governments.
