Duke of Braganza

Definition and stakes

Portrait of Martin A. S. Hume Martin A. S. Hume The Court of Philip IV.: Spain in Decadence

The Duke of Braganza, the Portuguese pretender with the best right to the throne, was prodigiously rich and over cautious, but his virile Spanish Guzman wife was eager and ambitious; whilst her wealthy brother, the Duke of Medina Sidonia, head of the Guzmans, silently helped forward the scheme which would make his sister a Queen, and afford him, the most powerful vassal of the Castilian crown, a precedent for the creation of an independent principality for himself in Andalucia, free from the weak and corrupt bureaucracy led by his cousin Olivares in Madrid.

He was so deeply learn'd in the Art of Intriguing, that he could perpetually make the Nobility jealous of one another, then would he foment their Divisions, and encrease their Animosities, whereby the Spanish Government became every day more absolute; for the Duke was assur'd, that whilst the Grandees were engag'd in private Quarrels, they would never think of the Common Cause.
The Duke of Braganza was the only Man in all Portugal, of whom the Spaniards were now jealous. His Humour was agreeable, and the chief thing he consulted was his Ease. He was a Man rather of sound Sense, than quick Wit.
