Treaty of Lisbon

During this lecture, it was highlighted that 2009 marks two important events for Europe: the 20th anniversary of the fall of the Berlin Wall, and, with the coming into force of the Treaty of Lisbon on December 1, the end of the third stage in the construction of Europe, which during the period 1990-2009 saw a major enlargement of the Union to include new members together with a first attempt at establishing a European Constitution.
