Juan II of Castille (1405–1454)
Pages 4

As king, Juan lacked interest in governing, preferring to rule through his favored minister, Álvaro de Luna (1385-1453). Luna served the king for forty years-as page, soldier, statesman, and confidant-progressively achieving total control over Juan’s will and the realm. His unparalleled power angered other feudal lords, ensuring conspiracies and strife throughout Juan’s reign.
