At first, there was a great deal of support for the Treaty of Versailles in the US. Many American governors and state legislatures endorsed the Treaty and the League of Nations when Wilson returned from Europe. Even so, the Treaty was rejected by the Senate.
There were many reasons for this rejection. Some of them include:
- Liberals were upset with Wilson for backing away from his 14 Points.
- German and Irish groups in the US were unhappy with the war in general and did not support the treaty.
- There was a strong sense of isolationism among many and those people would not want to commit to membership in the League.
Because of these sorts of doubts, there was opposition to the Treaty in the Senate. Over time, support for the Treaty died out among the public and the Treaty was not ratified by the Senate.
