The European Union, as a complex political system, is a space where processes resulting from multifaceted and contradictory forces emerge. As a result, building the system's adaptability and stabilisation (prointegration) capacity requires specific steps and actions. Operating within the EU consists in navigating through contradictory, often mutually exclusive activities whose nature reflects the nature of being a member of a supranational organisation. As a result, building a stable structure seems unattainable, and instead, a structure that is exposed to permanent crises and lack of sustainable growth is created. The aim of the current study is to look at the dynamics of integration processes through the lens of destabilising (crises) and modernising factors, which allow the system to return to the state of relative functional balance.
