This chapter examines the crises that dominated the period after the Lisbon Treaty was adopted in 2009: first, the eurozone crisis that began in 2009 and threatened the existence of the single currency; second, the refugee crisis that unfolded from 2015 as large numbers of refugees fled an intensifying war in Syria and attempted perilous crossings of the Mediterranean Sea; third, Britain’s decision to leave the EU, which followed a referendum on membership in 2016; and finally, the challenge of populist politics in the EU, with reference to the emergence of governments led by or including populist parties in Hungary, Poland, and Italy. The chapter then considers other developments during this period, including elections to the European Parliament (EP) in 2014 and 2019, a further enlargement to include Croatia in 2013, and the launch of the ‘Europe 2020’ strategy. It also looks at the United Kingdom’s adoption of a series of measures that raised doubts about its future relationship with the EU.
