The EU's Common Security and Defence Policy

The Common Security and Defence Policy (CSDP) is the security and defence policy for the EU. It forms an integral part of the EU’s foreign policy, the Common Foreign and Security Policy (CFSP).

SUMMARY

The Common Security and Defence Policy (CSDP) is the security and defence policy for the EU. It forms an integral part of the EU’s foreign policy, the Common Foreign and Security Policy (CFSP).

WHAT DOES THE CSDP DO?

It creates a framework for the military and defence aspects of EU policy. Created when the Treaty of Lisbon was signed in 2009, the CSDP replaces and enlarges the former European Security and Defence Policy (ESDP). The aim of the policy is the establishment of a common European defence capability.

KEY POINTS

BACKGROUND

The idea of a common defence policy for Europe dates back to 1948 with the Treaty of Brussels (signed by the UK (1), France and the Benelux countries), which had a mutual defence clause that paved the way for the Western European Union (WEU). Since then, European security policy has followed several different paths, developing simultaneously within the WEU, NATO and the EU.
