The Treaty of Versailles was signed in 1919 and punished Germany for its role in World War I. Germany was required to pay large sums of money, reduce its military, and admit responsibility for the war. The harsh punishments caused problems such as economic struggles and political instability in Germany. This led to extremist groups like the Nazi Party gaining power, and ultimately to World War II. Additionally, the treaty created anger and resentment in Germany, leading to a desire for revenge and increased militarism, which also contributed to the outbreak of World War II. Overall, the Treaty of Versailles had negative effects on global peace and caused significant geopolitical issues and conflicts.
