“…Theoretically, we combine various strands of European integration research in a novel theoretical framework that focuses on (i) how changes in the external environment (Sandholtz and Zysman, 1989; Lavery and Schmid, 2021; Schimmelfennig 2021) (ii) create an opening for actors to challenge a hegemonic compromise (van Apeldoorn, 2002; Bulmer and Joseph, 2016; Warlouzet, 2017) during which (iii) ambiguous ideas can be used as coalition magnets to forge a new compromise (Jabko, 2006; Béland and Cox, 2016).
