A lesson from the Austro-Hungarian Empire

I particularly like stories which relate historical events to modern problems.  Here is a story from planet money which compares the current economic crises in Greece and Italy to the breakup of the Austro-Hungarian Empire in 1918.  (They lost World War I, and got carved up into several smaller countries.)  Using this historical precedent, they are able to answer the question of what would happen of Greece were to try to leave the Euro-zone and return to its own national currency.
