Henry II, king of Castile and León (d. 1379)

Henry II (Enrique II), born on 13 January 1334 and passing away on 29 May 1379, holds a pivotal place in Castilian history as the first monarch from the House of Trastámara to rule the united crowns of Castile and León. His ascension marked a significant shift in the Iberian Peninsula's political landscape, following a protracted civil conflict.

Titles and Origins

Known by two distinct appellations, Henry II's legacy is intrinsically linked to his family and his path to power:

The Path to the Throne: The Castilian Civil War (1351-1369)

Henry II's rise to kingship was not through peaceful succession but through a long and brutal conflict against his half-brother, Peter I. This internal strife, known as the Castilian Civil War, was fueled by Peter I's authoritarian rule, his conflicts with the Castilian nobility and the Church, and his foreign policy alliances. Henry, as the eldest illegitimate son of King Alfonso XI, became the rallying figure for the disaffected noble factions who sought to depose Peter I.

The civil war was deeply intertwined with the larger European conflict, the Hundred Years' War, drawing in major foreign powers:

The war culminated in the decisive Battle of Montiel in 1369. Following a siege, Peter I was captured, and in a notorious incident, Henry personally slew his half-brother, effectively ending the conflict and securing his claim to the throne of Castile and León.

Reign and Foreign Engagements (1369-1379)

As king, Henry II faced the immediate challenge of consolidating his power and stabilizing a kingdom ravaged by years of civil war. He achieved this through a combination of political maneuvering, reconciliation, and strategic alliances. His reign was characterized by Castile's active involvement in two major international conflicts:

The Fernandine Wars (1369-1371, 1372-1373, 1375-1379)
These were a series of three conflicts fought against Ferdinand I of Portugal. The primary causes included disputes over the Castilian succession (as Ferdinand I also claimed the Castilian throne), and control over vital maritime trade routes and strategic territories along the Castilian-Portuguese border. Henry II generally emerged victorious from these engagements, consolidating Castilian dominance in the region.
The Hundred Years' War
Castile became a key player in this ongoing Anglo-French conflict under Henry II. Abandoning his half-brother's English alliance, Henry II solidified a strong alliance with France. This strategic partnership was critical, particularly concerning naval power. In 1372, the Castilian fleet, under the command of Ambrosio Boccanegra, achieved a decisive victory over an English fleet at the Battle of La Rochelle. This significant naval triumph severely crippled English naval capabilities in the Atlantic for years and provided France with crucial naval superiority, allowing them to exert greater pressure on English holdings in Gascony.
