Final answer:
The collapse of the Old Europe during the interwar period led to the rise of dictatorships in Europe as a result of weak leadership, economic instability, and disillusionment with democratic governments.
Step-by-step explanation:
The collapse of the Old Europe during the interwar period led to the rise of dictatorships in Europe. This was primarily caused by the devastation and dislocations of World War I, which highlighted weak leadership, economic instability, and disillusionment with democratic governments. Totalitarian leaders such as Benito Mussolini in Italy and Adolf Hitler in Germany took advantage of these circumstances and exploited the economic and political instability to gain power.
