Abstract

The works by Giuliano Procacci concerning the history of the labour movement from the period and issues of the Second International Age to socialism and communism in Europe between the World Wars; from the Italian labour movement, its forms of organization and geography, to the international impact of the developments in the Soviet Union present an important approach and make an internationally acknowledged contribution, from the methodological viewpoint as well, to this kind of historiography. But they also lay the groundwork for a more comprehensive and globally oriented investigation in the contemporary world, its different protagonists, and its interdependences. The questions raised by the historian Procacci are those of a changing history in a changing world.
