Vance Commission

The term Vance Commission is most commonly used to refer to the diplomatic missions led by Cyrus Vance, the former U.S. Secretary of State under President Jimmy Carter, who served repeatedly as a United Nations and international mediator in the 1990s. It is not a single standing body but rather shorthand for several initiatives he headed.

The most prominent use refers to Vance's role as Personal Envoy of the UN Secretary-General for the former Yugoslavia, appointed by Javier Pérez de Cuéllar in October 1991. In this capacity, Vance negotiated the Vance Plan, a ceasefire arrangement signed in Sarajevo and Geneva in late 1991 and early 1992, which led to the deployment of the United Nations Protection Force (UNPROFOR) in Croatia and the creation of UN Protected Areas (UNPAs) in Serb-held territories.

In 1992, Vance partnered with Lord David Owen, the EC representative, in what became known as the Vance–Owen Peace Plan for Bosnia and Herzegovina. The plan, presented in January 1993, proposed dividing Bosnia into ten semi-autonomous ethnic cantons under a decentralized central government. It was accepted by the Bosnian Croats and, conditionally, the Bosnian government, but rejected by the Bosnian Serb assembly at Pale in May 1993, contributing to the plan's collapse.

Vance also chaired or co-chaired related working groups under the International Conference on the Former Yugoslavia (ICFY), convened in London in August 1992. Separately, he mediated the 1995 Interim Accord between Greece and the Republic of Macedonia, which deferred the name dispute and normalized bilateral relations.

For MUN delegates and researchers, references to a "Vance commission" should be checked carefully against context: the phrase may denote his Yugoslav envoy work, the Vance–Owen process, his Macedonia mediation, or, in older U.S. policy literature, the 1980 hostage-rescue review board he led after the failed Iran rescue mission.
