located in the Monastery of Santa María de Sigena until the year 1301 and then moved to Barcelona. In the early 15th century, the de facto capital was Valencia until Alfonso V came to the throne. During the 15th and the 16th centuries, the Crown's de facto capital was Naples. After Alfonso V of Aragon, Ferdinand II of Aragon settled the capital in Naples. Alfonso, in particular, wanted to transform Naples into a real Mediterranean capital and lavished huge sums to embellish it further. Later the courts were itinerant until Philip II of Spain. The Spanish historian Domingo Buesa Conde has argued that Zaragoza ought to be considered the permanent political capital, but not the economic or administrative capital, owing to the obligation for kings to be crowned at the Cathedral of the Savior of Zaragoza. Culture During the Crown of Aragon, the Catalan culture and language underwent a vigorous expansion. During the period of trade, Occitan-Catalan contributions to Maltese occurred. King Fernando II and Queen Isabella, as the Catholic Monarchs who began the Inquisition, were contrary to the more plural development that preceded in the Crown of Aragon. The previous religious background was described as "longstanding tradition of Mudejarism, the royal sanctioning and protection of subject Muslim populations within Christian realms." Aesthetic Mudéjar architecture of Aragon has been observed as demonstrating the influence of Andalusian and Arab culture in Aragon proper. Gothic architecture was also developed. The Mediterranean Lingua Franca was a mixed language used widely for commerce and diplomacy and was also current among slaves of the bagnio, Barbary pirates and European renegades in precolonial Algiers. Among the speakers who created the language, also called Sabir, were Muslims from Aragon called "Tagarins" (a term mentioned by Miguel Cervantes). Historically, the first to use it were the Genoese and Venetian trading colonies in the eastern Mediterranean after the year 1000. The similarities contribute to discussions of the classification of Lingua Franca as a language. Although its official classification is that of a pidgin, some scholars adamantly oppose that classification and believe it would be better viewed as an interlanguage of Italian. Linguist Steven Dworkin hypothesized that Catalan was the point of entry for Mediterranean Lingua Franca terms into Spain, arguably the source of several Italian and Arabic loanwords in Spanish, citing the DCECH. Composition The crown was made up of the following territories (which are nowadays parts of the
