MEDICIS, Alexander de, first duke of Florence in 1530, was natural son of Laurence de Medicis, surnamed the Younger, and nephew of Pope Clement VII. He owed his elevation to the intrigues of his uncle and to the arms of Charles V. This prince having made himself master of Florence after an obstinate siege, conferred the sovereignty of this city on Alexander, and afterwards gave him in marriage Margaret of Austria his natural daughter. According to the terms of capitulation granted to the Florentines, the new duke was to be only hereditary duke, and his authority was tempered by councils; which left them at least a shadow of their ancient liberty. But Alexander, who felt himself supported by the emperor and the pope, was no sooner in possession of his new dignity, than he began to govern like a tyrant; being
guided by no law but his own caprice, indulging the most brutal passions, and making light of dishonouring families, and of violating even the asylum of the cloisters to gratify his lust. Among the confidants of his debauchery was a relation of his own, Laurence de Medicis. This young man, who was only 22 years of age, at the instigation of Philip Strozzi, a zealous republican, conceived the design of assassinating Alexander, and thereby of delivering his country from oppression. From the moment when he first became attached to him, he tried to gain his confidence, for no other reason but that he might the better have it in his power to take away his life. A considerable time elapsed before he found such an opportunity as he desired. At length, under pretence of procuring the duke a tête à tête with a lady of whom he was deeply enamoured, he brought him alone and unattended into his chamber, and put him under his bed. He went out, under pretence of introducing the object of his passion; and returned along with an assassin by profession, to whom alone he had entrusted his design, only to stab him. This cruel scene happened on the night betwixt the 5th and 6th of January 1537. Alexander was only 26 years of age. The Florentines derived no advantage from this crime of Laurence, for they failed in their attempt to recover their liberty. The party of the Medicis prevailed, and Alexander was succeeded by Cosmo: whose government, it must be confessed, was as just and moderate, as that of his predecessor had been violent and tyrannical. Laurence de Medicis fled to Venice, to some of the leaders of the malecontents at Florence, who had taken refuge there; but not thinking himself in sufficient security, he went to Constantinople, whence he returned some time after to Venice. He was there assassinated in 1547, ten years after the duke's murder, by two soldiers, one of whom had formerly been in Alexander's guards: And these soldiers were generous enough to refuse a considerable sum of money, which was the price put upon his head.
