The Common Security and Defence Policy (CSDP), formerly known as the European Security and Defence Policy (ESDP), is a major element of the Common Foreign and Security Policy of the European Union (EU) and is the domain of EU policy covering defence and military aspects, as well as civilian crisis management. The ESDP was the successor of the European Security and Defence Identity under NATO, but differs in that it falls under the jurisdiction of the European Union itself, including countries with no ties to NATO.
