Believing that cooperation and dialog among the countries of South-Eastern Europe must be further developed and considering their commitment to contribute to regional security and stability, and to foster good neighborly relations, among the countries, an Agreement on Multinational Peace Force South-Eastern Europe (MPFSEE) was signed by the Ministers of Defense of the seven participating countries in Skopje on 26 September 1998.
In accordance with MPFSEE Agreement, the South-Eastern Europe Brigade (SEEBRIG) was established and activated by seven participating Nations, on 31st of August 1999 in Plovdiv, Na-2, then was hosted in Constanta, Na-6 from 2003 to 2007 , then it  was located in Istanbul, Na-7 between 2007-2011, then in Tyrnavos/Larissa, Na-3, from 2011 to 2020, and then in Kumanovo, Na-5, between 2020-2026; since July 2026, SEEBRIG HQ has been hosted in Ayazağa Military Barracks in Istanbul, Na-7 .

The current structure of the MPFSEE is a brigade-sized force of about 5000 troops and is known as South-Eastern Europe Brigade (SEEBRIG).

Units allocated to the SEEBRIG will remain at their permanent home base locations and will be committed under a task force principle for exercises and operations upon the decisions of the participating Nations and appropriate joint direction and coordination of the “Politico-Military Steering Committee (PMSC)”.
