The twofold – political and economic – revolution that took place between the XVIII and XIX centuries imposed a new political protagonist: the masses. These had found full political legitimacy in the principle of popular sovereignty, whose abolition was maybe the main issue promoted by the post-Revolution intents of the Congress of Vienna (1814-1815). The power of the Restoration to impose a return to the principle of the legitimisation of divine power proved to be inconsequential and, in any case, did not extend beyond the year 1848.

In actual fact, the Nineteenth century distinguished itself for the deep hostility shown by the ruling class towards the masses, considered sometimes as the starting point for a new potential type of tyranny or, alternatively, as the means whereby the qualities of the individual could be lost and thus make man degenerate into barbarism. In this sense we can say that the masses maintained even a sort of protagonist role! Nevertheless, it must be underlined that the ruling class itself was constantly interested in involving the masses around its élite project. It was this very necessity that triggered those strategies that in the post-unitary period were known as “popular education”. The theatre of this complex and even paradoxical situation (what G.

However this process – aimed at transforming this de-stabilizing element into a structural potentiality – was assigned even more to the army. On the one hand it appeared a safer place to keep at bay any risks deriving from such an experiment, on the other hand the same liberal ruling class felt an urgent need of the utility of a mass army. As time went by, a strong link was created between this increasing attention towards the masses and the military dimension; as confirmation of ...
