Afonso IV, often celebrated as Afonso the Brave (Portuguese: o Bravo), reigned as the seventh King of Portugal from 1325 until his death on 28 May 1357. Born on 8 February 1291, his 32-year tenure on the Portuguese throne was marked by significant internal struggles and external conflicts that solidified the kingdom’s position in the Iberian Peninsula. As the only legitimate son of King Denis of Portugal, renowned for his economic reforms and cultural patronage, and Saint Elizabeth of Aragon, a queen celebrated for her piety and peacemaking efforts, Afonso IV inherited a kingdom poised for both stability and challenge.

Early Life and Dynastic Tensions

The early life of Afonso IV was significantly overshadowed by a contentious relationship with his father, King Denis. Despite being the sole legitimate heir, Afonso often found himself in direct opposition to Denis, particularly over the king's favoritism towards his illegitimate son, Afonso Sanches. This preferential treatment ignited a series of civil conflicts, pitting father against son in a struggle for power and recognition. These disputes frequently forced Queen Elizabeth of Aragon, canonized as Saint Elizabeth of Portugal, to mediate between them, playing a crucial role in preventing full-scale civil war and ensuring a smoother, albeit turbulent, succession.

Upon King Denis’s death in 1325, Afonso IV ascended to the throne. His first act as monarch was decisive: he banished Afonso Sanches to Castile, consolidating his authority and putting an end to the internal strife that had plagued the royal family for years.

The Reign of Afonso IV: Defining Moments

Afonso IV's 32-year reign was characterized by a blend of military prowess and shrewd political maneuvering, earning him the epithet "the Brave." His commitment to safeguarding Portuguese independence and influence was evident in both internal and external affairs.

Military Engagements and the "Brave" Epithet

• The Battle of Salado (1340): A pivotal moment that largely cemented his reputation as "the Brave" was his crucial participation in the Battle of Salado. This joint military campaign saw the forces of Portugal, led by Afonso IV, and Castile, under Alfonso XI, decisively defeat the invading Marinid army from Morocco and their Nasrid allies from Granada. This monumental victory, fought near Tarifa, Spain, was critical in halting the advance of the Marinids into the Iberian Peninsula, preserving Christian control, and is considered one of the last major battles of the Reconquista. Afonso IV's significant contribution of a contingent of Portuguese knights and his tactical command were vital to the allied triumph.
• Conflicts with Castile: Despite the alliance at Salado, relations with Castile were often fraught. Afonso IV engaged in periodic skirmishes and diplomatic maneuvers to protect Portugal's borders and dynastic interests against the powerful Castilian kingdom, particularly during the reign of Alfonso XI.

Internal Administration and Royal Authority

Domestically, Afonso IV focused on strengthening royal authority and maintaining order. His reign saw efforts to centralize power, curb the influence of the nobility, and administer justice effectively. He also continued some of his father's work in promoting the development of the Portuguese navy and encouraging maritime trade, laying groundwork for future overseas expansion, though this was not a primary focus of his reign.

The Tragic Affair of Inês de Castro

A significant, and ultimately tragic, aspect of Afonso IV's later reign involved the forbidden romance between his son and heir, Pedro (later King Peter I), and Inês de Castro, a Castilian noblewoman and lady-in-waiting to Pedro's wife, Constance of Castile. Afonso IV vehemently opposed this relationship, fearing the growing Castilian influence through Inês and her family at the Portuguese court, and concerned for the legitimacy of the succession. Despite his efforts to separate them, Pedro and Inês continued their affair, even having several children. In a controversial decision in 1355, Afonso IV, advised by his council, ordered the execution of Inês de Castro. This act, intended to secure the stability of the kingdom, instead plunged the realm into a period of civil unrest known as the "War of Pedro and Afonso," where the heir openly rebelled against his father. While the conflict eventually subsided with reconciliation, the deep wounds caused by this event would profoundly impact Peter I's reign and become a legendary tale in Portuguese history.

Legacy of Afonso IV

Afonso IV's reign, though often tumultuous, cemented the foundations of an independent Portuguese monarchy. He successfully defended the kingdom's borders, asserted royal power, and played a crucial role in the broader Iberian political landscape, most notably through his contribution to the victory at Salado. While his handling of the Inês de Castro affair remains a dark chapter, his reign is ultimately remembered for the strength and resilience he brought to the Portuguese crown amidst significant challenges.
