In which year did Mussolini seize power in Italy?

Mussolini seized power in Italy in 1922, when he orchestrated a march on Rome, which was a key moment in establishing his dictatorship. Prior to this, Mussolini had been building his political strength, capitalizing on the social unrest and dissatisfaction in post-World War I Italy. The march on Rome led King Victor Emmanuel III to invite Mussolini to form a government, marking the beginning of Fascist rule in Italy. This pivotal year is significant as it set the stage for the totalitarian regime that Mussolini implemented, which would have lasting implications for Italy and Europe during the interwar period. The other years listed do not pertain to Mussolini's rise to power: 1918 was shortly after the war ended and saw no transition to his leadership, while the years 1925 and 1928 were subsequent years that fell within Mussolini’s consolidation of power rather than the initial seizure.
