Manuel I of Portugal: "The Fortunate" and His Unexpected Rise to the Throne

Manuel I of Portugal (r. 1495–1521), later known as "the Fortunate" (O Venturoso), was never expected to become king. However, due to political purges, the untimely deaths of key heirs, and the favor of King John II, Manuel unexpectedly became the heir to the Portuguese throne in 1493.

Royal Lineage and Family Background

Manuel’s mother, Beatriz of Portugal, was the granddaughter of King John I, giving him strong royal connections.
His father, Infante Fernando, Duke of Beja, was the second surviving son of King Edward and the younger brother of King Afonso V.
This made Manuel a nephew of King Afonso V and a cousin of King John II.

Growing Up Amidst Conspiracies and Noble Purges

Manuel came of age during King John II’s ruthless crackdown on the nobility (1483–1484).
His older brother, Diogo, Duke of Viseu, was personally stabbed to death by John II in 1484, accused of leading a noble conspiracy against the Crown.
Many other nobles were executed, exiled, or had their lands confiscated, leaving Manuel to witness the dangerous political environment of his time.

A Shocking Royal Summons (1493)

Given his family history, Manuel had every reason to fear for his life when he was summoned by King John II in 1493.
However, instead of punishment, he received extraordinary news—John II wanted to name him heir to the throne.

Why Was Manuel Chosen as Heir?

Death of Prince Afonso (1491)
- John II’s only legitimate son, Prince Afonso, died in a horse-riding accident in 1491, leaving the king without a direct heir.
Failed Attempts to Legitimize Jorge, Duke of Coimbra
- John II attempted to legitimize his illegitimate son, Jorge, Duke of Coimbra, as heir.
- However, this move faced opposition from the nobility and Queen Leonor (Manuel’s sister).
Manuel’s Political Neutrality
- Unlike other nobles, Manuel had never conspired against the king.
- His lack of political ambition and royal bloodline made him a safe choice.

Manuel I: "The Fortunate"

Manuel’s unexpected rise to power earned him the nickname "O Venturoso" (The Fortunate).
In 1495, John II died, and Manuel I became King of Portugal, ushering in Portugal’s Golden Age of Exploration.

Legacy and Impact

Under Manuel I, Portugal expanded its global empire, with Vasco da Gama reaching India (1498) and Pedro Álvares Cabral discovering Brazil (1500).
He continued centralizing royal authority while maintaining noble support, ensuring a stable reign.
His selection as heir marked the final success of John II’s effort to weaken the aristocracy, as Manuel owed his throne to the king’s favor rather than noble alliances.
