The Eurozone crisis refers to a financial situation that began in late 2009, affecting countries that use the euro as their currency. It was triggered by high levels of public debt in several member states, particularly Greece, Ireland, Portugal, Spain, and Italy. These countries faced difficulties in repaying their debts, leading to fears of default and economic instability within the European Union. To address the crisis, the European Central Bank and other institutions implemented various measures, including financial bailouts and austerity programs. These efforts aimed to stabilize the economies of affected countries and restore confidence in the eurozone as a whole.
