Historiographical investigation persists in an unjustified inattention to the juridical vicissitudes in the Kingdom of Portugal and the Algarve despite being the theatre - as evidenced by the quadruple royal codification - of extraordinary moments in the experience of modern law.

The State-Church relations and their respective forums in the jurisdictionalist storm of the seventeenth century do not escape these dynamics of transformation. The close confrontation that pitted Nuncios and Apostolic Collectors against the Philippine prince and his ministers gave rise to a sui generis jurisdictionalism, quite different from the coeval European models. With the exception of the episcopal forum, the ecclesiastical courts of the post-Tridentine period, the inquisitorial and ius fisci, lose their importance because the Atlantic lineage of Ulysses honours the tradition of the homeland law, the 'estylo do Reino', corroborated by portentous royalist jurists and a vital jurisprudence.
