vague overlordship on the part of the church, or of the emperor or of a king. Others were parts of kingdoms, or even the capitals of dukes or kings. In such cases their internal freedom was maintained by a royal or imperial charter. In England the Royal City of Westminster on the Thames stood cheek by jowl with the walled city of London, into which the King came only with ceremony and permission. The entirely free Venetian republic ruled an empire of dependent islands and trading ports, rather after the fashion of the Athenian republic. Genoa also stood alone. The Germanic towns of the Baltic and North Sea from Riga to Middelburg in Holland, Dortmund, and Cologne were loosely allied in a confederation, the confederation of the Hansa towns, under the leadership of Hamburg, Bremen, and Lubeck, a confederation which was still more loosely attached to the empire. This confederation, which included over seventy towns in all, and which had dépôts in Novgorod, Bergen, London, and Bruges, did much to keep the northern seas clean of piracy, that curse of the Mediterranean and of the Eastern seas. The Eastern Empire throughout its last phase, from the Ottoman conquest of its European hinterland in the fourteenth and early fifteenth century until its fall in 1453, was practically only the trading town of Constantinople, a town state like Genoa or Venice, except that it was encumbered by a corrupt imperial court.
The fullest and most splendid developments of this city life of the later Middle Ages occurred in Italy. After the end of the Hohenstaufen line in the thirteenth century, the hold of the Holy Roman Empire upon North and Central Italy weakened, although, as we shall tell, German Emperors were still crowned as kings and emperors in Italy up to the time of Charles V (circ. 1530). There arose a number of quasi-independent city states to the north of Rome, the papal capital. South Italy and Sicily, however, remained under foreign dominion. Genoa and her rival, Venice, were the great trading seaports of this time; their noble palaces, their lordly paintings, still win our admiration. Milan, at the foot of the St. Gothard pass, revived to wealth and power. Inland was Florence, a trading and financial centre which, under the almost monarchical rule of the Medici family in the fifteenth century, enjoyed a second "Periclean age." But
