Henry, the cardinal-king or Henrique (in Portuguese) the Chaste (Port. o Casto) (January 31 1512 - January 31 1580), was the seventeenth King of Portugal between 1578 and 1580. He was the younger brother of king John III and, as a younger son, Henry was not expected to succeed to the Portuguese throne. Early in his life, Henry took Holy Orders to promote Portuguese interests within the Catholic Church, then dominated by Spain. He rose fast through the Church hierarchy, becoming in quick succession Archbishop of Braga, Archbishop of Evora and Grand Inquisitor before receiving a Cardinal's hat. Henry, more than anyone, endeavoured to bring the Jesuit order to Portugal and employed them in the colonial empire. He served as regent for his grand-nephew, Sebastião, after 1557, and then 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, affiliated with the Habsburgs did not release him from his vows. The Cardinal-King died without having appointed a Council of Regency to choose a successor. The closest dynastic claimant was King Philip II of Spain who, in November 1580, sent the Duke of Alba to claim Portugal by force. Lisbon soon fell, and Philip was elected King of Portugal on condition that the kingdom and its overseas territories would not become Spanish provinces.
