The Treaty of Versailles was very unpopular in Germany. Many Germans felt that the treaty was too harsh and that it was unfair to blame Germany for starting World War I. The treaty also contributed to the rise of Adolf Hitler and the Nazi Party in Germany.
The Treaty of Versailles was eventually revised in 1939, after the outbreak of World War II. The new treaty, known as the Treaty of Munich, allowed Germany to annex Austria and the Sudetenland. The Treaty of Munich was widely seen as a failure of appeasement, and it contributed to the outbreak of World War II.
Overall, the Treaty of Versailles was not successful. It was unpopular in Germany, it contributed to the rise of Hitler and the Nazi Party, and it failed to prevent the outbreak of World War II.
