In greece, austerity measures undertaken to bring down the national debt triggered street demonstrations in 2011. how did later events play out?

Greece needed bailouts on debts owed. Reactions against austerity programs continued.

In 2012, banks agreed to accept just 26 cents for every dollar owed. French and German banks were key players in this action. There was concern that a complete default of the Greek situation would damage confidence in the European Union economy as a whole. There were other vulnerable, indebted nations also. There were continued internal political struggles regarding how much "austerity" (tightening of budget) the Greek government could handle. By 2015, Greece was still struggling. By this time, there was less willingness to provide debt relief to Greece, but Greek voters in a national referendum strongly rejected a bailout program that was offered that had strict terms. Further negotiations provided yet another plan. Greece continues to struggle financially. As of January 2018, the Greek parliament agreed to another round of austerity measures.
