Treaty of Lisbon
At the meeting of the European Council in October 2007, Portugal insisted that the Treaty (then called the 'Reform Treaty') be signed in Lisbon, the Portuguese capital. This request was granted, and the Treaty was thus to be called the Treaty of Lisbon, in line with the tradition of European Union treaties. The Portuguese presidency was appointed to the job of organising the programme for a signing ceremony.
