Chargé d'Affaires (MUN)

In real diplomatic practice, a chargé d'affaires is the head of a diplomatic mission ranked below an ambassador or minister, as classified by the 1961 Vienna Convention on Diplomatic Relations (Article 14). There are two types: a chargé d'affaires en pied (or en titre), who is the permanent head of mission accredited to the receiving state's foreign minister rather than head of state, and a chargé d'affaires ad interim, who temporarily leads a mission when the ambassador is absent, recalled, or the post is vacant.

In Model UN, the title is used in a few distinct ways:

• Delegation rank: Some conferences, particularly those simulating bilateral or General Assembly settings with multi-member delegations, designate one delegate as "Ambassador" and others as "Chargé d'Affaires" or attachés. The chargé typically handles substantive negotiation on specific committees while the ambassador coordinates overall delegation strategy.
• Crisis committees: In historical or crisis simulations involving strained diplomatic relations — for example, scenarios in which two states have downgraded ties — a delegate may explicitly portray a chargé d'affaires rather than an ambassador, reflecting that recall of ambassadors is a common signal of diplomatic displeasure.
• Awards and recognition: A few conferences use "Chargé d'Affaires" as an award tier below "Best Delegate" or as an honorific for head delegates of visiting school delegations.

Delegates portraying a chargé should remember that the role carries full diplomatic functions under the Vienna Convention but signals reduced political weight. Historically, the United States has operated through chargés d'affaires in countries such as Cuba (until 2015), Syria, and Venezuela during periods of suspended ambassadorial relations, making the title a useful marker in simulations of contemporary diplomatic tension.
