In Model UN crisis committees, an arc is the sequence of private notes (often called "crisis notes" or "directives") a delegate sends to the backroom to build power, resources, or influence outside the formal debate. The resolution of that arc is the climactic point at which the backroom decides whether the delegate's scheme succeeds, fails, or transforms into something unexpected.
Typical arcs include accumulating military assets, running a coup, founding a shadow organization, assassinating a rival, or developing technology. The arc usually unfolds in stages: setup notes establish capability, follow-up notes deploy it, and the backroom responds with crisis updates that either reward, complicate, or punish the plan. A well-resolved arc ties back into committee debate — for example, a delegate whose private army succeeds in seizing a capital can then push the full committee to recognize the new government.
Backroom staff (the Crisis Director and Assistant Crisis Directors) generally look for several qualities before granting a favorable resolution:
- Plausibility given the character's real powers and resources
- Specificity — named operatives, locations, timelines, budgets
- Integration with the committee's front-room arc and other delegates' plots
- Narrative payoff rather than pure power-maximizing
Arcs can also resolve negatively: an over-extended delegate may be arrested, exposed in a joint crisis update, or killed off. Many circuits consider a dramatic failure as award-worthy as a success, provided the delegate reacts in character. Conferences such as HNMUN, WorldMUN, ChoMUN, and McMUN are known for elaborate crisis arcs spanning multiple committee sessions.
Strong delegates plan the resolution before sending the first note, working backward from the desired endgame and seeding earlier notes with the assets and alibis the final move will require.
Example
At ChoMUN 2023's Joint Crisis on the Wars of the Roses, a delegate playing the Earl of Warwick resolved a multi-session betrayal arc by switching sides mid-committee, triggering a crisis update that collapsed the Yorkist front.
Frequently asked questions
Most experienced delegates seed the foundational notes in the very first committee session, since backrooms reward arcs that show patient buildup rather than sudden power grabs.
