The position of the crowns of Castile and aragon from the Ottoman conquest of constantinople and the subsequent Ottoman expansions from 1453 to 1492

Abstract EN

This research examines the position of the European states, in particular the crowns of Castile and Aragon, in the Iberian Peninsula from the fall of Constantinople.

It argues with previous studies the claim that the Ottoman seizure of Constantinople increased enthusiasm for crusading throughout Europe against the Ottomans.

To this end, this research discusses the statuses of the Christian states in Europe, particularly the Iberian crowns.

It looks as well at the primary objectives of the crowns in the Iberian Peninsula.

In addition, it compares the reactions of Castile and Aragon after the Ottoman capture of Constantinople and their responses after the Ottoman conquest of Otranto in the Italian Peninsula.

The methodology of this study is the historical method, which analyses various primary sources, including Castilian, Aragonese, Muslim and papacy sources.

The analysis of these sources provides arguments in order to dispute the theses of the previous studies.
