It may come as a surprise to some of our younger readers, that the Eurozone, and its associated currency, is merely the latest in a long series of failed attempts to create a European currency union and a common currency. Three of the most notable predecessors to the EUR include the Hapsburg Empire, the Soviet Union, and Yugoslavia. Obviously, these no longer exist. Just as obvious, all of these unions, having spent time, energy, money, and effort to change the culture and traditions of member countries and to perpetuate said unions, had no desire, just like Brussels nowadays, to see these unions implode. The question then is: what happened after these multi-nation currency unions fails. VOX kindly answers: "they all ended with disastrous hyperinflation."
