The Politics of the Ancient Constitution is a close examination of the political ideas of common lawyers in early Stuart England, and includes important surveys of the ideas of Sir Edward Coke and John Selden. It provides an original interpretation of the lawyers' theory of the ancient constitution and on this basis it provides a novel interpretation of the basic structure of political thought and ideology in pre-Civil War England. In this way the book is able to make a substantial contribution to debates over the ideological origins of the English Revolution.
