What This Standard Means

What Students Need to Do

Students compare Wilson’s Fourteen Points with the final peace treaty. They explain why senators opposed League of Nations membership and how concerns about sovereignty, war powers, and compromise shaped the vote.

What Mastery Looks Like

Students use evidence from speeches or treaty excerpts to explain at least two Senate objections. They distinguish between rejecting the treaty, declining League membership, and avoiding all contact with other nations.

Common Misconceptions

Students may think the president could approve the treaty without the Senate. They may also assume all opponents shared one motive, or that the United States completely withdrew from world affairs.

How to Assess It

Give an exit ticket asking: Why did some senators oppose League membership, and what constitutional concern supported their position? Require two specific details.

Ways to Teach It

  1. Have pairs sort cards labeled Fourteen Points, treaty terms, and Senate objections, then match each objection to the relevant proposal.

  2. Ask students to write: Should collective security outweigh congressional control over war decisions? Support your answer with two historical details.

  3. Run a mock Senate vote with students assigned as Wilson supporters, reservationists, or irreconcilables, each using a short evidence card.

  4. Compare the League debate with a modern alliance commitment, asking students who should decide when the nation sends troops or aid.
