For the conclusion of this chapter, I have reserved the Genoese war, which shook the throne of Cantacuzene, and betrayed the debility of the Greek empire. The Genoese, who, after the recovery of Constantinople, were seated in the suburb of Pera or Galata, received that honorable fief from the bounty of the emperor. They were indulged in the use of their laws and magistrates; but they submitted to the duties of vassals and subjects; the forcible word of _liegemen_43 was borrowed from the Latin jurisprudence; and their _podesta_, or chief, before he entered on his office, saluted the emperor with loyal acclamations and vows of fidelity. Genoa sealed a firm alliance with the Greeks; and, in case of a defensive war, a supply of fifty empty galleys and a succor of fifty galleys, completely armed and manned, was promised by the republic to the empire. In the revival of a naval force, it was the aim of Michael Palæologus to deliver himself from a foreign aid; and his vigorous government contained the Genoese of Galata within those limits which the insolence of wealth and freedom provoked them to exceed. A sailor threatened that they should soon be masters of Constantinople, and slew the Greek who resented this national affront; and an armed vessel, after refusing to salute the palace, was guilty of some acts of piracy in the Black Sea. Their countrymen threatened to support their cause; but the long and open village of Galata was instantly surrounded by the Imperial troops; till, in the moment of the assault, the prostrate Genoese implored the clemency of their sovereign. The defenceless situation which secured their obedience exposed them to the attack of their Venetian rivals, who, in the reign of the elder Andronicus, presumed to violate the majesty of the throne. On the approach of their fleets, the Genoese, with their families and effects, retired into the city: their empty habitations were reduced to ashes; and the feeble prince, who had viewed the destruction of his suburb, expressed his resentment, not by arms, but by ambassadors. This misfortune, however, was advantageous to the Genoese, who obtained, and imperceptibly abused, the dangerous license of surrounding Galata with a strong wall; of introducing into the ditch the waters of the sea; of erecting lofty turrets; and of mounting a train of military engines on the rampart. The narrow bounds in which they had been circumscribed were insufficient for the growing colony; each day they acquired some addition of landed property; and the adjacent hills were covered with their villas and castles, which they joined and protected by new fortifications. 44 The navigation and trade of
