The Regency Struggle and the Afonsine Ordinances…

The Regency Struggle and the Afonsine Ordinances (1433–1446)

Following the death of King João I of Portugal in 1433, the crown passed to his eldest son, Duarte I, whose brief five-year reign (1433–1438) was cut short by the plague. His death left the kingdom in political uncertainty, as his heir, Afonso V, was only six years old.

Duarte I’s Reforms and the Afonsine Ordinances

• Before his death, Duarte had convened a Cortes to begin the compilation of Portuguese royal law.
• This legal work would not be completed until the reign of Afonso V, when it was published as the Afonsine Ordinances (Ordenações Afonsinas).
• Duarte also declared that the land grants given by his father João I must be confirmed at the start of each reign, ensuring royal authority over noble holdings.

The Struggle for the Regency (1438–1446)

Upon Duarte’s death in 1438, his widow, Queen Eleanor of Aragon, assumed the regency, but she faced strong opposition from the nobility and the populace, who refused to accept a woman as sole ruler.

The Rival Factions

• Infante Pedro, Duke of Coimbra (Duarte’s brother)

  • Popular in Lisbon and supported by the merchants and middle class.
  • A skilled administrator and advocate for strong royal authority over the nobility.
  • Sought to strengthen his influence by marrying his daughter Isabel to the young King Afonso V.

• Afonso, Duke of Bragança (João I’s eldest illegitimate son)

  • Leader of the old nobility, including those who had gained extensive land grants under João I.
  • Opposed Pedro’s regency, as he feared it would curb noble privileges.
  • Attempted to secure power by marrying his own daughter to Afonso V.

Pedro’s Victory and Regency (1439–1448)

• The Lisbon populace strongly favored Infante Pedro, and he was officially recognized as regent after convening the Cortes of Évora in 1439.
• To secure his position, he arranged for his daughter, Isabel of Coimbra, to marry Afonso V once the young king reached his majority.
• When Afonso V turned 14 in 1446, he upheld the marriage agreement and requested Pedro to continue governing.

Aftermath and Future Conflicts

• Although Pedro remained in power, tensions with Afonso, Duke of Bragança, did not subside.
• When Afonso V fully assumed power in 1448, Bragança’s faction maneuvered to have Pedro removed.
• This power struggle would ultimately lead to the Battle of Alfarrobeira in 1449, where Pedro was killed, marking the triumph of the nobility over royal centralization.

The Afonsine Ordinances, the Lisbon merchants’ support for Pedro, and the ducal rivalry between Pedro and Bragança all shaped the political structure of Portugal for decades, reinforcing tensions between royal authority and aristocratic power.
