France has played an important role in all the European Union's history. Multiple relations exist between France and the European Union, political, social and economic relations which have evolved since the first step of a European cooperation. It seems interesting to analyse these relations, by focusing especially on the economic area, and the role of France in the European Union and bring out its involvement. The relation between France and the European Union has been often described as a "hate-love relationship". This paper will bring out the historical involvment of France in the European Union, from the first agreement in 1951 to the Treaty of Lisbon in December 2009. The analyse will also focus on the European Union as several institutions; as well as the Eurozone and its economic consequences in Europe and in France. The paper will raise monetary and institutional issues and develop the most important European stakes as the enlargements, the European budget, the common policies and the European institutions.
