Henry Cabot "Slim" Lodge (May 12, 1850 – November 9, 1924) was an AmericanRepublican politician from Massachusetts. He served in the U.S. House of Representatives from 1887-1893 and then in the U.S. Senate from 1893-1924. Lodge is usually credited as the first (albeit unofficial) Republican Senate Majority leader, serving from 1920-1924. Lodge is probably best remembered for his conservative politics and for his conflict with PresidentWoodrow Wilson over the Treaty of Versailles. While both men did favor the Treaty overall, Lodge's opposition to Article X, which Lodge believed would require the U.S. to wage war without a vote in Congress, collided with Wilson's refusal to amend the treaty at all.
