Taking a deep look into History, and its several specialties, its current considerable social predicament arise. In fact, wide social groups and communities encounter their historical origins along the different historical periods and, with them, an essential element for their historical identity. There is no doubt that in such identity is is a representation of the classical heritage represented by the Greco-Roman world, always a higly valued object which has been increased during the last years. Indeed, the constitution of the European Union has fostered the search for common principles in the Western World, which culturally speaking are found in Greece and, politically speaking, in Rome. Several congresses, seminars, publications, etc., as well as the enhancement of heritage remains from this period, which have promoted the consolidation and encouragement of the legacy from the Classical World. Historical bonds that relate us to all the fields which were a part of the classical world, shall be considered as the undoubtful links with the former territories of the Crown of Aragon. Aragon, Valencia, Catalonia and Majorca, whose names clearly transmit that they are historical units composed in the medieval period and with a common past, institutionally manifested in the existence of the Crown of Aragon. Theses territories (which should be added to Sicily, Naples, Sardinia and Roussillon) are of obvious interest in the development of researches in medieval history in the Crown of Aragon and its current political, social and cultural institutions which are thoroughly integrated in the European culture from a historical perspective of training throughout the continent, which is manifested through the financing of scientific activities (congress, meetings, commemorations), publications, archaeological diggings, heritage restoration and many others in terms of cultural actions. These considerations may also be applied to Modern History, a period which, after fixing its roots in the Medieval Ages, opens up to the Contemporary World to offer all the explicative keys which give an answer to the questions risen by the current world.

This greco-latin heritage from Ancient times interpreted in the High Medieval Ages Germanic Reigns, made it possible for the historical fundaments of the Western European World to be constructed, with national monarchies and their international projection on a precise geography, delimited by the Mediterranean, the Atlantic, the Northern Sea, the Baltic and the ends of the western continent.
