Here is a revised edition of a major work on Fascism in the country of its origin. It describes the impact of a new type of political movement on Italian government and society. The Fascist seizure of power did not begin or end with Mussolini's March on Rome in October 1922; it was achieved rather by a gradual subversion of the liberal order which involved not only the destruction of all political opposition but also the creation of new institutions designed to control economic and cultural life.
