(EPC) brought about the European Communities' (EC) initial foreign policy coordination. Opposition to the addition of security and defence matters to the EPC led to the reactivation of the WEU in 1984 by its member states, which were also EC member states. European defence integration gained momentum soon after the end of the Cold War, partly as a result of the EC's failure to prevent the Yugoslav Wars. In 1992, the WEU was given new tasks, and the following year the Treaty of Maastricht founded the EU and replaced the EPC with the Common Foreign and Security Policy (CFSP) pillar. In 1996 NATO agreed to let the WEU develop a so-called European Security and Defence Identity (ESDI). The 1998 St. Malo declaration signalled that the traditionally hesitant United Kingdom was prepared to provide the EU with autonomous defence structures. This facilitated the transformation of the ESDI into the European Security and Defence Policy (ESDP) in 1999, when it was transferred to the EU. In 2003 the EU deployed its first CSDP missions, and adopted the European Security Strategy identifying common threats and objectives. In 2009, the Treaty of Lisbon introduced the present name, CSDP, while establishing the EEAS, the mutual defence clause and enabling a subset of member states to pursue defence integration within PESCO. In 2011 the WEU, whose tasks had been transferred to the EU, was dissolved. In 2016 a new security strategy was introduced, which along with the Russian annexation of Crimea, the British withdrawal from the EU and the election of Trump as US president have given the CSDP a new impetus. Deployments 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. Between May and September 2003 EU troops were deployed to the Democratic Republic of the Congo (DRC) during "Operation Artemis" under a mandate given by UN Security Council Resolution 1484 which aimed to prevent further atrocities and violence in the Ituri Conflict and put the DRC's
