What is Burden Sharing

European identity is an identity constructed everyday within the lives of Europeans. The emergence of this identity can be traced back to the 1970s when it was first introduced in the Copenhagen Declaration on European Identity (1973). The identity has changed a lot with each enlargement of the EU. It has enriched and evolved. But its construction has not been completed, as it is a process with no end. The EU has faced many crises and one of them that challenges identity is migration. It is a test for the EU, its identity, way of life, and values. This chapter analyses if migration is a threat to EU identity, how it became a challenge, and how the actors respond to this challenge. To find out how it became a challenge and how the actors, especially the Visegrad States' political leaders, respond to this challenge, the discourses of political actors are evaluated.
