For much of the history of European integration, the principal academic interest centred on developments at the European level with a particular focus on analysing the creation of supranational institutions as well as efforts to understand the forces which stimulated the ‘deepening’ of cooperation amongst ‘former enemies’ (Jensen 2007: 88). While there were certain disciplines, notably law and economics, where attention was given to the consequences of European-level cooperation on domestic legal and economic systems, this did not extend to the political sphere of European studies.
