When did Spain join the Euro zone?
Eurozone
Interest in joining the eurozone increased in Denmark, and initially in Poland, as a result of the 2008 financial crisis. In Iceland, there was an increase in interest in joining the European Union, a pre-condition for adopting the euro.[35] However, by 2010 the debt crisis in the eurozone caused interest from Poland, as well as the Czech Republic, to cool.[36] Latvia adopted the Euro in 2014, followed by Lithuania in 2015.[37]
