The 2007 enlargement of the European Union saw Bulgaria and Romania join the European Union (EU) on 1 January 2007. It was the expansion of the EU considered by the European Commission as part of the same wave (the fifth) as the 2004 enlargement.
Romania was the first country of post-communist Europe to have official relations with the European Community. In 1974, a treaty included Romania in the Community's Generalized System of Preferences. Since the Romanian Revolution of 1989, European Union (EU) membership has been the main goal of every Romanian Government and practically every political party in Romania. Romania signed its Europe Agreement in 1993, and submitted its official application for membership in the EU in 1995, the third of the post–communist European countries to do so after Hungary and Poland. Along with its official EU application, Romania submitted the “Snagov Declaration”, signed by all fourteen major political parties declaring their full support for EU membership.
