The United States Senate was opposed to the United States joining the League of Nations. There was a provision in the charter of the League of Nations, called Article X, which required member nations to commit troops if needed to help a member of the League of Nations fight if a war broke out and the League of Nations ordered military action. Article X might also require some other kind of diplomatic action that we might not want to do. These senators, called reservationists, were concerned about the United States getting involved in a war that we had no interest in joining or would have no impact on us. They also were concerned about losing some control over our foreign policy. These senators wanted to make changes to this part of the charter of the League of Nations. However, President Wilson didn’t want this to occur. As a result, we not only didn’t join the League of Nations, we didn’t ratify the Versailles Treaty. We ended up signing separate peace treaties with the Central Powers.
