Isabel of Castile and the Making of the Spanish Nation, 1451-1504
1915
In the autumn of her childhood in the rough hill towns of Castile, no one could have predicted that a girl born to a secondary line of the royal family would become one of the most consequential rulers in European history. Yet Isabel of Castile did precisely that, and this early twentieth-century account captures the full drama of her ascent: the political machinations, the dynastic marriages, the patient consolidation of power across the Iberian peninsula. Plunket examines her partnership with Ferdinand of Aragon as more than a marriage of convenience. It was the forging of a unified Spain from the chaotic scraps of medieval Christendom. The narrative reveals how their joint rule transformed a fractured collection of kingdoms into a nation capable of projecting power across the Atlantic. Yet the book refuses to soften the harder edges of Isabel's legacy. Her unwavering commitment to Catholic orthodoxy, manifested through the Spanish Inquisition, stands as a stark reminder that the drive for religious uniformity often came at terrible human cost. The same fierce determination that unified Spain also burned its heretics. Written in 1915, this account offers a window into how an earlier generation of historians grappled with the contradictions of a queen who remade Europe.
