The Euro and sovereign debt crises since 2008, as well as the following Great Recession, have challenged the strength of European solidarity between EU citizens and member states. This chapter analyses the strength of European solidarity within East Central Europe and other European countries in two dimensions: citizens’ willingness to support indebted European countries financially (European fiscal solidarity) and their willingness to reduce welfare differences among EU member states (European territorial solidarity). The analyses are based on a comparative survey conducted in 13 European countries in 2016. Results show that citizens displayed a notably high level of European solidarity in both dimensions. While ECE countries showed slightly lower approval rates for European fiscal solidarity, their demand for European territorial solidarity is average. However, Slovakia, Hungary and Poland do not form a unique cluster standing out on these topics, making further policies of European integration possible.
