In 1803 Robert Livingston and James Monroe were sent to France to negotiate the purchase of the Louisiana Purchase. Originally the two met set out only to purchase New Orleans and the surround territory, however, by the end they eventually purchased the massive track of land that extended beyond the Mississippi River which greatly expanded the size of the United States.

The League of Nations charter became part of the Treaty of Versailles following World War I. President Woodrow Wilson pushed hard for its passing, to the point that he earned the 1919 Nobel Peace Prize. However, when he brought the charter to the U.S. Congress, the members refused to ratify it. Thus, the international organization promoted by President Wilson never became a part of American politics.
