Struggle for the throne of Portugal

Overview
The 1580 Portuguese succession crisis came about as a result of the 1578 death of young King Sebastian I of Portugal in the Battle of Alcácer Quibir
Battle of Alcácer Quibir

. As Sebastian had no immediate heirs, this event prompted a dynastic crisis, with internal and external battles between several pretenders to the Portugese throne; in addition, because Sebastian's body was never found, several impostors emerged over the next several years claiming to be the young king, further confusing the situation.

The Cardinal-King


The Cardinal Henry, Sebastian's great-uncle, became ruler in the immediate wake of Sebastian's death. Henry had served as regent for Sebastian after 1557, and succeeded him as king after the disastrous Battle of Alcácer-Quibir in 1578. Henry renounced his clerical offices and sought to take a bride for the continuation of the Aviz dynasty, but Pope Gregory XIII

Claimants to the throne



Portuguese nobility was worried about the maintenance of their independence and sought help to find a new king. By this time the Portuguese throne was disputed by several claimants; among them were Catherine, Duchess of Braganza

 custom, her late older sister's son Rainuccio, an Italian, was the closest heir, then the Duchess herself, and only after them, King Philip. Philip II was a foreigner (although his mother was Portuguese) and descended from Manuel I by a female line; as for Anthony, although he was Manuel I's grandson in the male line, he was an illegitimate grandson.

Ranuccio Farnese (1569–1622), the hereditary duke of Parma and Piacenza, was the son of the late elder daughter of Duarte of Portugal, Duke of Guimarães, the only son of Manuel I whose legitimate descendants survived at that time, Ranuccio was according to the feudal custom the first heir to the throne of Portugal. He was the son of Alessandro Farnese, Duke of Parma and Piacenza, and of Maria of Portugal

Infanta Maria of Guimarães was a Portuguese infanta daughter of Infante Duarte, Duke of Guimarães , and Isabel of Braganza. She married Alessandro Farnese, Duke of Parma and Piacenza on November 11, 1565.-Issue:...

. His great-uncle Henry I of Portugal's death triggered the struggle for the throne of Portugal when Ranuccio was 11 years old. However, his father was an ally and even a subject of the Spanish king, another contender, so Ranuccio's rights were not very forcibly claimed at that time. Ranuccio became reigning duke of Parma in 1592.

Instead, Ranuccio's mother's younger sister Catherine, Duchess of Braganza, claimed the throne, very ambitiously, but failed. Catherine, Duchess of Braganza was married to Duke John I of Braganza (descendant in male line from Afonso, 1st Duke of Braganza

, also a legitimate heir of Portugal, being the son of infanta Isabella of Portugal, sister of Manuel I and daughter of infante Ferdinand, Duke of Viseu, second son of king Duarte I. The duchess also had a son, dom Teodosio de Braganza, who would be her royal heir and successor to the throne. The duchess's claim was relatively strong, as it was reinforced by her husband's position as one of the legitimate heirs; thus they would both be entitled to hold the kingship. Moreover, the Duchess was living in Portugal, not abroad, and was not underage, but 40 years old. Her weaknesses were her gender (Portugal had not had a generally recognized reigning queen) and her being the second daughter, there thus existed a genealogically senior claimant.

According to the old feudal custom, the line of succession of the Portuguese throne would have been:
  • Ranuccio I Farnese, Duke of Parma

Anthony and Philip


Anthony of Portugal (1531–1595), Prior of Crato, was a claimant of the Portuguese throne during the 1580 crisis and, according to some historians, King of Portugal (during a short time in 1580, in the continent, and since then until 1583, in the Azores

. It was precisely because of his illegitimacy that his claim to the throne was weak and considered invalid.

Consequences


The matter of whether Portugal was actually invaded by Spain is contested. It cannot be doubted that Philip II did have a legitimately arguable claim to the throne, but as with many other dynastic struggles of the age, it was shrouded in controversy. In any case, life was calm and serene under the first two Hapsburg kings; they maintained Portugal's status, gave excellent positions to Portuguese nobles in the Spanish Court
