How did world war 1 lead to totalitarianism?

World War I created political instability and economic turmoil in many countries, particularly in Europe, as nations struggled to rebuild and cope with the consequences of the war. The Treaty of Versailles, which imposed harsh reparations on Germany, fueled resentment and nationalist sentiments. In this climate of discontent, totalitarian leaders like Mussolini in Italy and Hitler in Germany exploited public fears and desires for stability, promising to restore national pride and order. This shift towards totalitarianism was further facilitated by the rise of Propaganda and the suppression of dissent, allowing these regimes to consolidate power effectively.
