Enrique de Villena (1384–1434), also known as Henry de Villeine and Enrique de Aragón, was a medieval Spanish marquess of Villena, writer, theologian and poet. He was also the last legitimate descendant of the old counts of Barcelona, the former royal house of Aragon. When political power was denied to him, he turned to writing. He was persecuted by Alfonso V of Aragon and John II of Castile owing to his reputation as a necromancer.
He was born in Torralba de Cuenca, in Castile. After the death of his father, Pedro de Aragón y Villena, Enrique went to the Aragonese court, where he was raised by his aristocratic grandfather, Alfonso de Aragón, first marquess of Villena. There he met the leading literary and intellectual minds of his era and became skilled in mathematics, chemistry and philosophy. The Aragonese Queen Violant of Bar, aware of Villena’s academic gifts, invited him to study at the royal court of Barcelona, where Villena met the leading authors of Catalan literature. This experience further solidified Villena’s already promising future.
However, Villena encountered difficulty towards the end of the fourteenth century when his grandfather began losing power in the Castilian court. By 1398, Alfonso had lost his position as marquess of Villena. This loss did not rest well with either Alfonso or Villena. Alfonso spent the next many years attempting to re-instate his grandson as marquess of Villena. Meanwhile, Villena straightforwardly declared himself Marquess of Villena – signing all official documents in this name, though not legally correct.
Historians believe Villena traveled to Castile during the first years of the fifteenth century, took residence there, and married María de Albornoz – a wealthy heiress from Cuenca, Spain. Continuing this rise towards aristocratic prominence, Villena soon received titles as count of Cangas and Tineo – offered to him by his cousin, King Henry III of Castile. However, in 1404, Villena resigned from the court to pursue world travel. Ironically, that same year, Villena tried to become master of the Order of Calatrava – a prestigious religious and military order. Pursuing this position, Enrique divorced his wife, claiming impotence, and renounced his position as count so he could officially become a friar of Calatrava. The King of Castile mandated that the comendadores (commanders) of Calatrava promote Enrique as master of the Order. This position, however, did not suit Villena well for, although intelligent, he was not politically competent. Authorities soon stripped him of his leadership position.
