Common Foreign and Security Policy
Previously, the post holder was also the High Representative for the Common Foreign and Security Policy, President of the European Defence Agency and the Western European Union. The Treaty of Amsterdam created the office of the High Representative for the Common Foreign and Security Policy and specified that the Secretary-General would occupy that position simultaneously. Javier Solana exercised both functions from 1999 until 2009. The Lisbon Treaty redefined the post of High Representative and again separated it from the office of Secretary-General of the Council.
