World War I profoundly transformed Italy's political landscape, setting the stage for decades of turbulence.
Italy's victory and territorial gains fueled intense nationalism, boosting patriotic ideologies across the country.
Economic hardship during the war strengthened socialist groups, which pushed for workers' rights and greater political representation.
Society fractured along ideological lines—liberals, conservatives, socialists, and nationalists clashed, leading to frequent government turnover and weak leadership.
Post-war crises created fertile ground for Benito Mussolini's Fascist movement, which promised order and national revival, attracting the disillusioned.
Fascists gradually dismantled civil liberties, suppressed dissent, and centralized power under Mussolini, culminating in a totalitarian dictatorship by the 1920s.
The industrialized north prospered while the agricultural south lagged, deepening regional tensions and challenging national unity.
War expanded industry and arms production, but post-war inflation and reconstruction struggles further destabilized society and politics.
