One of the most significant potential problems that occurred in Europe as a result of World War I and the Treaty of Versailles was the rise of nationalism. The Treaty of Versailles, which was signed at the end of World War I, imposed harsh terms on Germany and other Central Powers. This treaty caused a deep sense of resentment among the people of Germany, which in turn led to the rise of nationalist movements and a desire for revenge. This ultimately resulted in the rise of Nazi Germany and the outbreak of World War II.
Another potential problem that occurred in Europe as a result of World War I and the Treaty of Versailles was the weakening of the international order. The Treaty of Versailles was seen as overly punitive and it left a legacy of mistrust and instability in Europe. This weakened the international order and created a sense of mistrust between the European powers. Additionally, the weakening of the international order also had a more general impact on international relations, as it made it more difficult to resolve international disputes peacefully.
Hope this helped! Have a great day. :)
