“ GROWTH OF THE TOWNS: THE ITALIAN CITY-REPUBLICS. Relation of the Cities to the Feudal Lords.—When Feudalism took possession of Europe, the cities became a part of the system. Each town formed a part of the fief in which it happened to be situated, and was subject to all the incidents of feudal ownership. It owed allegiance to its lord, must pay to him feudal tribute, and aid him in his war enterprises. As the cities, through their manufactures and trade, were the most wealthy members of the Feudal System, the lords naturally looked to them for money when in need. ”
