Officially introduced in 1999, the euro was the realisation of a dream first mooted in 1929.
Intended to enable the free movement of capital and promote peace in Europe, the monetary union has become a source of political instability in its own right.
In the wake of the 2008 financial crisis, the steps of the bailout tango have become familiar. A nation struggling with debt denies it will need a loan, a loan is eventually granted by the EU and IMF, on the condition austerity measures are adopted; a further loan is sought and further loans are granted.
Across Europe election defeats for pro-bailout parties have been interpreted as a rejection of the austerity economics championed by German Chancellor Angela Merkel and British Prime Minister David Cameron. The struggling nations protest the human cost of austerity, while more stable economies resent footing the bill, and, in an irony Europhiles will find particularly cutting, press coverage often resorts to the kind of jingoistic name-calling last seen during World War II.
