Treaty of Versailles

The summit of Lodge's Senate career came in 1919 when as the unofficial Senate majority leader he did not want to secure approval of the Treaty of Versailles. See also
Lodge Committee
He also was the editor in Chief of the 24 volume History of Nations


Notes. (10 volumes).

He had the role (but not the title) of Senate Majority leader. Lodge demanded Congressional control of declarations of war; Wilson refused and the United States Senate never ratified the Treaty nor joined the League of Nations.
