Abstract
This chapter explores the intersection of three key migration and asylum dynamics: the reasons why people migrate internationally to (and from) EU member states; the responses to non-EU migration and asylum that have developed both at member state and EU level; and the political ‘framing’ of migration as an issue or challenge. We begin by asking why, how, and with what effects migration and asylum became salient political issues after the so-called ‘migration crisis’ of 2015, but contextualize these more recent developments by showing how responses after 2015 actually emerged from patterns of cooperation established since the 1980s.
