Beginning in 1922, Fascist paramilitaries escalated their strategy by switching from attacks on socialist offices and the homes of socialist leadership figures to the violent occupation of cities. The Fascists met little serious resistance from authorities and proceeded to take over several cities, including Bologna, Bolzano, Cremona, Ferrara, Fiume and Trent. The Fascists attacked the headquarters of socialist and Catholic unions in Cremona and imposed forced Italianization upon the German-speaking population of Trent and Bolzano. After seizing these cities, the Fascists made plans to take Rome.
