Sturzo made a distinction between the "filofascists", who left the Catholic PPI in 1921 and 1922, and the "clerical fascists" who stayed in the party after the March on Rome, advocating collaboration with the fascist government.[3] Eventually, the latter group converged with Mussolini, abandoning the PPI in 1923 and creating the Centro Nazionale Italiano. The PPI was disbanded by the fascist régime in 1926.[4]
