The first deployment of European troops under the ESDP, following the 1999 declaration of intent, was in March 2003 in the former Yugoslav Republic of Macedonia (FYROM, today: North Macedonia). Operation Concordia used NATO assets and was considered a success and replaced by a smaller police mission, EUPOL Proxima, later that year. Since then, there have been other small police, justice and monitoring missions. As well as in the FYROM, the EU has maintained its deployment of peacekeepers in Bosnia and Herzegovina, as part of Operation Althea.
