Medieval Spain: Castile & Aragon's Transformation (14th-15th C.)

The Late Medieval Crisis (13th-15th Centuries)

Economic and Demographic Challenges

The European Middle Ages, particularly from the 13th to the 15th centuries, was a period of profound crisis characterized by famine, pestilence, wars, and social conflicts. Poor harvests and difficulties in importing grain led to a severe subsistence crisis across Spain. The arrival of the Black Death in 1348 further exacerbated the situation. Despite various measures, the widespread depopulation generated a significant rise in prices and wages.

Political and Social Unrest

Politically, the interests of the nobility and royal power clashed, often at the expense of the clergy. Attempts to increase royal authority frequently led to social tensions, with farmers staging several anti-seigneurial rebellions. Additionally, a series of devastating civil wars ravaged Castile, Navarre, and Catalonia.

Castile: Institutions & Transformation (14th-15th C.)

The Late Medieval period in Castile (14th-15th centuries) was marked by an agrarian and demographic crisis, clashes between the nobility and the king, social tensions, and civil wars. Key developments included:

• The dynastic change to the House of Trastámara.
• The expansion of the seigneurial regime.
• Increased engagement with the Atlantic.
• A demographic and economic recovery during the 15th century.

Strengthening Royal Authority

From a political standpoint, the era emphasized the strengthening of royal authority. This was influenced by the spread of theories about the divine origin of royal power, which fostered the development of new institutions and greater centralization.

Centralization of Power

Significant institutional reforms included the fusion of the Cortes of Castile and León. This led to the creation of a Royal Council (1385), primarily composed of jurists, and the Audiencia (1371) as the supreme organ of justice.

Local Governance Reforms

At the local level, royal control increased through the establishment of regiments with councilors appointed by the king. The appearance of the regidor (alderman) further enhanced oversight, with their role focused on resolving local issues and preventing corruption.

Aragon: Institutional Structure (13th-15th C.)

A Confederation of Territories

The political structure of the Crown of Aragon from the 13th to the 15th centuries was characterized as a confederation of territories, each possessing its own distinct laws and institutions. The relationship between the ruler and the governed remained firmly within the feudal concept of pacts or covenants, emphasizing mutual obligations.

Key Aragonese Institutions

Among the most important institutions were:

• The Viceroy: A representative who assumed the role of the monarch in their absence.
• The Cortes: These assemblies defended the interests of the nobility, clergy, and gentry. They later evolved into permanent Deputations of the different kingdoms, responsible for organizing and controlling tax collection. This led to the formation of bodies such as the Generalitat (Government) of Catalonia, the Diputación del Reino de Aragón (Provincial Deputation of the Kingdom of Aragon), and the Diputación del Reino de Valencia (Provincial Deputation of the Kingdom of Valencia).
• The Justicia de Aragón: An independent legal figure who defended the specific rights and privileges (fueros) of Aragon.
• Municipal Government: Formed by a delegado (delegate) and municipal councilors, managing local affairs.

Iberian Expansion and Trade

Aragon's Mediterranean Dominance

Despite facing similar crisis factors as Castile, Aragon successfully pursued significant expansion in the Mediterranean from the 13th to the 15th centuries. Territories like Catalonia, Valencia, and Mallorca were crucial to this endeavor, leading to the incorporation of Sicily, Sardinia, and Naples into the Crown of Aragon. Even Athens and Neopatria, conquered by the Almogavars, became part of its influence.

This expansion fostered active international trade, leading to the growth of the port of Barcelona. Barcelona exported textiles and imported goods such as iron, grain, and leather from other territories. Aragon's greatest commercial glory occurred in the 14th century, but the severe crisis of the 15th century saw Valencia replace Barcelona as the main commercial port of the Crown of Aragon.

Castile's Atlantic Ambitions

Castile's expansion primarily focused on the Atlantic. Its initial external actions aimed to secure dominance in the south of the Iberian Peninsula, exemplified by the taking of Algeciras. This conquest granted Castilian control over the Strait of Gibraltar.

Seville and other Andalusian ports became essential stepping stones for journeys between the Mediterranean and the Atlantic. Italian (Genoese) traders and bankers settled in these areas, contributing to the development of shipbuilding. Basque sailors began to dominate maritime commerce, with Cantabrian ports like Bilbao exporting wool and iron to France, England, and Flanders.
