On December 13, 2007, leaders of the 27 member nations of the European Union (EU) signed the Treaty of Lisbon in an effort to reform the decision-making process of the EU and allow the union to have a more active role in global issues. This event was followed by close to two years of intense negotiations as the governments of the various member nations ratified the document. The treaty went into effect on December 1, 2009.
