Biography
Mosén Diego de Valera (1412–1488) was a Spanish nobleman, historian, and writer from the Crown of Castile. His contributions and eventful life marked the shift from medieval to Renaissance thought in 15th-century Spain. Born in Cuenca, Valera was known for both his scholarly works and his military involvements, which took him beyond the Iberian Peninsula, including the Hussite Wars in Bohemia. These experiences as a warrior and scholar later influenced his writings on governance, nobility, and Spanish history.
Valera's writings showed his deep involvement with the political and social issues of his time. His most influential work, Espejo de verdadera nobleza (1439–41), argued that true nobility came from virtue and education, not just bloodline. This view highlighted the early impact of Renaissance humanism in Castile and was a major shift from traditional aristocratic beliefs. His work contributed to discussions on merit-based social hierarchy that became more prominent during the Renaissance.
As a political commentator, Valera wrote to Spanish monarchs John II of Castile and Henry IV of Castile, offering advice and warnings about governance. He used biblical and historical examples to remind these rulers that bad leadership often led to being overthrown. He referred to Old Testament kings and thirteen Gothic rulers who lost their thrones due to tyranny, suggesting similar outcomes for unworthy monarchs. Indeed, King Henry IV was deposed in 1465, confirming Valera's warnings about royal responsibility.
Besides his political writings, Valera also contributed to military literature and history. He wrote one of the earliest known fencing manuals, the Treatise on Arms, which offered practical swordsmanship instruction. His historical account, the Crónica de España abreviada (1481), summarized Spanish history based on the Chronicle of 1344. This chronicle later became a main source for the Crónica popular del Cid (1498), ensuring that Valera's historical views influenced later chroniclers and shaped public understanding of Spanish medieval history.
Before Fame
Diego de Valera was born into a noble family in Cuenca, Spain, during a time of big changes in the Crown of Castile. The early 1400s were marked by challenges to old medieval systems from new humanist ideas and ongoing political instability. Young nobles like Valera were typically taught skills in combat, writing, and court manners, preparing them to be both fighters and advisors to the crown.
To become a recognized intellectual in 15th-century Castile, it was often necessary to engage directly with Europe's wider cultural and political world. Valera's adventures as a knight led him to places like Bohemia, where he joined the Hussite Wars, gaining firsthand experience in religious conflict, military tactics, and different political systems. This international experience, along with his noble background and education, helped him become an influential figure in Spanish intellectual and political circles when he returned to Castile.
