a Spanish politician and diplomat. His early career was that of a government official and diplomat. In 1563 he gained the king's confidence as his representative at Rome. In 1568 he was appointed lieutenant-general to John of Austria during the suppression of the Morisco Revolt in the Alpujarras, and he also accompanied John during the Lepanto campaign, his function being to watch and control his nominal commander-in-chief, whose excitable temperament was distrusted by the king. In 1572 Philip named him Governor of the Duchy of Milan, a post usually given to a great noble. Requesens was only a gentleman, though by the kings favour he was grand commander of the military order of Santiago in Castile.
