The euro should now be recognized as an experiment that failed. This failure, which has come after just over a dozen years since the euro was introduced, in 1999, was not an accident or the result of bureaucratic mismanagement but rather the inevitable consequence of imposing a single currency on a very heterogeneous group of countries. The adverse economic consequences of the euro include the sovereign debt crises in several European countries, the fragile condition of major European banks, high levels of unemployment across the eurozone, and the large trade deficits that now plague most eurozone countries.
The political goal of creating a harmonious Europe has also failed. France and Germany have dictated painful austerity measures in Greece and Italy as a condition of their financial help, and Paris and Berlin have clashed over the role of the European Central Bank (ECB) and over how the burden of financial assistance will be shared.
The initial impetus that led to the European Monetary Union and the euro was political, not economic. European politicians reasoned that the use of a common currency would instill in their publics a greater sense of belonging to a European community and that the shift of responsibility for monetary policy from national capitals to a single central bank in Frankfurt would signal a shift of political power.
The primary political motive for increased European integration was, and may still be, to enhance Europe's role in world affairs.

Europe will be your revenge." One year later, the Treaty of Rome launched the Common Market.
The Common Market expanded in 1967 to form the European Communities, and then, in 1992, the Maastricht
