However, a variety of political and economic obstacles barred the way. Weak political commitment, divisions over economic priorities and turbulence in international markets all played their role in frustrating progress towards EMU.
Despite these obstacles, the second half of the 20th century saw a constant search by the growing number of EU Member States for deeper economic integration as a means of strengthening the political bonds between them and protecting the common market.
The road towards today's Economic and Monetary Union and the euro area can be divided into four phases:

The international currency stability that reigned in the immediate post-war period did not last.

In response to this troubling background, Europe's leaders set up a high-level group led by Pierre Werner, the Luxembourg Prime Minister at the time, to report on how EMU could be achieved by 1980.
Phase 2: From the Werner Report to the European Monetary System, 1970 to 1979
