Why were antidemocrstic leaders able to take power in the soviet union and Italy after world war 1?

Antidemocratic leaders rose to power in the Soviet Union and Italy after World War I due to widespread social, economic, and political instability. In the Soviet Union, the Bolsheviks capitalized on discontent from war fatigue and economic hardship, promoting a radical revolutionary agenda. Similarly, in Italy, the post-war economic crisis and political fragmentation allowed Benito Mussolini and the Fascists to exploit fears of communism and chaos, ultimately promising order and national revival. Both regimes relied on Propaganda, repression, and the disillusionment of the populace to consolidate their power.
