FERDINAND & ISABELLA: FERDINAND II (1452-1516) King of Aragon 1479-1516 and, as Ferdinand V, King of Castile jure uxoris 1474-1504 & ISABELLA I (1451-1504) Queen of Castile 1474-1504.
A good D.S. by both Ferdinand V ('Yo el Rey') and Isabella I ('Yo la Reyna') individually, at the foot, one page, oblong 8vo, n.p., 22nd July 1493, in Spanish. The boldly penned manuscript document authorises Juan de Ribera to act as their agent and states, in full, 'We beseech Don Juan de Ribera, Our Captain General in the frontier of Navarre and of Our Council, that he may speak to you of our transaction which we place at your disposal and we request that you fully vouch for and guarantee to the effect that such deed be executed' Countersigned at the foot by Fernando Alvarez, Secretary to the Monarchs, beneath a holograph statement ('Por mandato del Rey y de la Reyna'), mandating the document. With some extremely light, very minor age wear, otherwise a clean and handsome document, VGFerdinand II and Isabella I were bestowed the title of Rex Catholicissimus ('Catholic Monarchs') by Pope Alexander VI in 1494, the year after signing the present document, in recognition of their defence of the Catholic faith within their realms.The marriage of the Catholic Monarchs became the basis for the political unification of Spain under their grandson, Holy Roman Emperor Charles V, and Ferdinand and Isabella are also recognised for completing the Reconquista, as well as ordering conversion or exile of their Muslim and Jewish subjects in the Spanish Inquisition.However, their place in history is more commonly associated with the support and finance they granted with their sponsorship of Christopher Columbus for his first voyage of 1492 which led to the opening of the New World and to the establishment of Spain as the first global power which dominated Europe and much of the world for more than a century.The present document is dated between the first voyage of Columbus, which concluded on 15th March 1493, and the commencement of his second voyage on 24th September 1493.
