The paper endorses a dynamic rather than a static analysis of the EU at super-systemic level of analysis. It sketches a toolkit to analyse the actors and contents of constitutional politics, exploiting the insights of the main grand theories, based on the interpretative scheme of crisis-initiative-leadership, and the distinction between unification, integration and construction. Applying this toolkit, a trend towards an increase of the EU federal features can be discerned. Eventually, to overcome the current crisis more steps in this direction are needed.
