Role-Play: Treaty Negotiation Simulation

Assign roles to Irish and British delegates with briefing sheets on positions. Groups negotiate key terms like Dominion status and partition over two rounds, recording concessions. Debrief with whole-class vote on acceptance.

Prepare & details

Analyze the pressures faced by the Irish delegation during the Treaty negotiations.

Facilitation Tip: In the Treaty Negotiation Simulation, assign students roles with specific talking points and secret pressures to ensure tension and realism during debate.

Setup: Desks rearranged into courtroom layout

Materials: Role cards, Evidence packets, Verdict form for jury

Jigsaw

⏱ 45 min·Small Groups

Jigsaw: Key Provisions Analysis

Divide class into expert groups on oath, Dominion status, partition, and boundary. Each group analyzes sources and teaches peers. Pairs then compare implications for sovereignty.

Prepare & details

Explain the concept of Dominion status and its implications for Irish sovereignty.

Facilitation Tip: For the Jigsaw, group students by Treaty provisions and require each group to prepare a two-minute summary using only their assigned clause and one primary source.

Setup: Flexible seating for regrouping

Materials: Expert group reading packets, Note-taking template, Summary graphic organizer

Formal Debate

⏱ 60 min·Whole Class

Formal Debate: Treaty For or Against

Form pro- and anti-Treaty teams with evidence cards. Teams prepare 3-minute opening statements, rebuttals, and closing arguments. Class votes and reflects on historical parallels.

Prepare & details

Critique the arguments for and against accepting the Treaty terms.

Facilitation Tip: During the Debate, provide a visible tally board for arguments and evidence so students track how provisions sway opinions in real time.

Setup: Two teams facing each other, audience seating for the rest

Materials: Debate proposition card, Research brief for each side, Judging rubric for audience, Timer

Source Sort: Pressures on Delegation

Provide letters, telegrams, and memos. Individuals sort into categories like military threat, public opinion, economic factors. Pairs justify sorts and link to decisions.

Prepare & details

Analyze the pressures faced by the Irish delegation during the Treaty negotiations.

Facilitation Tip: In the Source Sort, have students categorize documents by type (ultimatum, private letter, public statement) to reveal how genre shapes perception of pressure.

Teaching This Topic

Teachers should avoid framing the Treaty as a simple victory or failure, since the Dáil split shows its complexity. Research suggests using cold-call during simulations to hold students accountable for Treaty terms, and circulating with primary sources during debates keeps discussions grounded. Modeling how to parse legal language helps students avoid oversimplifying terms like 'Dominion status'.

What to Expect

Successful learning looks like students distinguishing Dominion status from republic status, weighing short-term gains against long-term costs, and articulating pressures on the Irish delegation with evidence. Classroom discussion should reveal multiple perspectives, not just one correct answer.

Watch Out for These Misconceptions

Common Misconception

During the Role-Play: Treaty Negotiation Simulation, watch for students claiming the Treaty granted full independence.

What to Teach Instead

Redirect groups by asking them to compare the Treaty's Dominion language to the 1916 Proclamation's republic language, using their role sheets and primary sources to highlight the shared monarchy requirement.

Common Misconception

During the Jigsaw: Key Provisions Analysis, watch for students stating partition was fixed at six counties.

What to Teach Instead

Ask each group to trace the Boundary Commission clause on their provision sheet and map the uncertainty it created, using the timeline to show the 1925 report as a revision, not a confirmation.

Common Misconception

During the Debate: Treaty For or Against, watch for students attributing the signing solely to Collins.

What to Teach Instead

Prompt students to refer to the plenipotentiary powers document and Griffith's role in their arguments, using peer feedback to distribute agency across the Irish delegation.

Assessment Ideas

Discussion Prompt

After the Role-Play: Treaty Negotiation Simulation, facilitate a class-wide debate where students draw on their simulation experiences to justify Treaty votes as TDs in 1922.

Quick Check

During the Jigsaw: Key Provisions Analysis, ask each group to share one pressure revealed in their assigned primary source and explain its impact on the negotiations before moving to the next clause.

Exit Ticket

After the Source Sort: Pressures on Delegation, collect exit tickets where students define two key terms and explain how Dominion status differed from full independence, using their sorted sources as evidence.

Extensions & Scaffolding

• Challenge early finishers to draft a one-paragraph speech defending their Treaty vote as if they were a TD in 1922, including a counterargument to their own position.
• Scaffolding for struggling students involves providing sentence starters for Treaty clause comparisons, such as 'The oath meant... while Dominion status allowed...'.
• Deeper exploration involves assigning students to research how the Boundary Commission's 1925 report altered the map of Northern Ireland and present their findings.
