Why were the antidemocratic leaders able to take power in the Soviet Union and Italy after World War 1?

Antidemocratic leaders like Vladimir Lenin in the Soviet Union and Benito Mussolini in Italy capitalized on social and economic turmoil following World War I, including widespread disillusionment with existing governments and the harsh realities of post-war conditions. In Russia, the Bolsheviks promised peace, land, and bread, appealing to the war-weary populace and leveraging the chaos of the Russian Revolution. Similarly, Mussolini exploited Italy's economic struggles, social unrest, and national humiliation from the war to rally support for his fascist movement, promoting a vision of national revival. Both leaders used propaganda, political violence, and the manipulation of public sentiment to dismantle democratic institutions and consolidate their power.
