The MSI included a large variety of currents, which ranged from republicans to monarchists, Catholics to anti-clericals, conservative capitalists to radical anticapitalists, and revolutionaries to corporatists. The party was mainly divided between the adherents of what Renzo De Felice called the "fascism-movement" and the "fascism-regime", roughly also corresponding to the party's "northern" and "southern" factions. The former "leftist"-tendency was more militant and radical, and claimed heritage from the socialistic and anti-bourgeois "republican" fascism of the Italian Social Republic and pre-1922 fascism, as represented by the Fascio d'Azione Rivoluzionaria. The latter drew more from the mainstream clerical, conservative, authoritarian, and bourgeois fascist tendency that prevailed after the stabilisation of the fascist regime.
>Most of the party's initial leaders were northern radicals, but most of its support was from voters in the South. In the North, the party elite to a large extent consisted of highly ideological veterans from the civil war. As the Italian Social Republic (RSI) had not existed in the South, and there thus had been no civil war, the southern MSI-supporters and notables were by contrast largely moderate-conservatives, less interested in ideology. When the conservatives gained power of the party in the 1950s, they steered it more towards the traditional clerical and monarchist right-wing.Fascism the regime>fascism the movement
