In September 1919, the nationalist response of outraged war hero Gabriele D'Annunzio was declaring the establishment of the Italian Regency of Carnaro. To his independent Italian state, he installed himself as the Regent "Duce" and promulgated the "Carta del Carnaro" ("Charter of Carnaro", 8 September 1920), a politically syncretic constitutional amalgamation of right-wing and left-wing anarchist, proto-fascist and democratic republican politics, which much influenced the politico-philosophic development of early Italian Fascism. Consequent to the Treaty of Rapallo (1920), the metropolitan Italian military deposed the Regency of "Duce" D'Annunzio on Christmas 1920. In the development of the fascist model of government, D'Annunzio was a nationalist and not a fascist, whose legacy of political–praxis ("Politics as Theatre") was stylistic (ceremony, uniform, harangue and chanting) and not substantive, which Italian Fascism artfully developed as a government model.
