Notwithstanding the uniform prudence of his conduct, an affair afterwards took place which made him in some degree suspected by the prime minister, though don John had not the smallest share in the business. The people of Evora, made desperate by fresh taxes, rose in arms, and in the fury of seditious rage, some of the most violent declaimed against the tyranny of the Spaniards, and publicly breathed forth wishes in favour of the house of Braganza. It was then perceived, but too late, how greatly Philip the IId. had erred, in permitting so rich and powerful a family to remain in a newly conquered country, over which their right of reigning was but too clearly proved. So circumstanced, the Spanish council decided on removing the duke of Braganza from the kingdom; he was accordingly offered the government of the Milaneze, which he refused, alledging that neither his health, nor his acquaintance with Italian affairs, would allow of his accepting so important and difficult an appointment. The minister appeared to acquiesce in these reasons, whilst he endeavoured to hit upon another method to engage him to visit the court. The king's projected journey to the frontiers of Arragon, to punish the rebellious Catalonians, was a plausible pretence for his joining the party; he therefore wrote earnestly to exhort him to join the Castillian troops at the head of the nobility of his country in an expedition which must end gloriously, and in which the king commanded in person. The prime minister, with a view of weakening the power of the Portugueze nobles, had already published an edict of Philip the IVth, commanding all hidalgos to repair immediately to the army raised against the Catalonians, on pain of losing their fiefs dependant on the crown; he therefore hoped, that the duke of Braganza, as hereditary constable of Portugal, could not be dispensed from marching on the occasion. The duke, however, mistrusting all propositions on the part of the court, and seeing through the artifice of its proceedings, entreated the minister to induce the king to accept his excuses, on account of the enormous expences which must be incurred by a person of his dignity, and which he declared he was entirely unable to support. Such repeated refusals began to alarm the minister; he was, indeed, perfectly well acquainted with the mild and peaceable disposition of the duke, yet he could not help fearing, that his claims to the throne having been forcibly held up to his view, the temptation of reigning might in the end have surmounted the natural indolence of his character.
