On 15 April 1919, the Fascists made their debut in political violence, when a group of members from the "Fasci di Combattimento" attacked the offices of "Avanti!". Recognizing the failures of the Fascists' initial revolutionary and left-leaning policy, Mussolini moved the organization away from the left and turned the revolutionary movement into an electoral movement in 1921 named the "Partito Nazionale Fascista" (National Fascist Party). The party echoed the nationalist themes of D'Annunzio and rejected parliamentary democracy while still operating within it in order to destroy it. Mussolini changed his original revolutionary policies, such as moving away from anti-clericalism to supporting the Roman Catholic Church and abandoned his public opposition to the monarchy. Support for the Fascists began to grow in 1921 and pro-Fascist army officers began taking arms and vehicles from the army to use in counter-revolutionary attacks on socialists.
