At the end of the fourteenth century their informal lordship passed by a royal grant into an acknowledged duchy of the Empire. The dominion which they had gradually gained, and which was thus in a manner legalized, took in all the great cities of Lombardy, those especially which had formed the Lombard League against the Swabian Emperors. ♦County of Pavia.♦ Pavia indeed, the ancient rival of Milan, kept a kind of separate being, and was formed into a distinct county. ♦Extent of the duchy.♦ But the duchy granted by Wenceslaus to Gian-Galeazzo stretched far on both sides of the lake of Garda. _Belluno_ at one end and _Vercelli_ at the other formed part of it. It took in the mountain lands which afterwards passed to the two Alpine Confederations; it took in _Parma_, _Piacenza_, and _Reggio_ south of the Po, and _Verona_ and _Vicenza_ in the old Austrian or Venetian land. Besides all this, _Padua_, _Bologna_, even _Genoa_ and _Pisa_, passed at various times under the lordship of the Visconti. But this great power was not lasting. The Duchy of Milan, under various lords, native and foreign, lasted till the wars of the French Revolution; but, long before that time, it had been cut short on every side. ♦Decrease on the death of Gian Galeazzo, 1402.♦ The death of the first Duke was followed by a separation of the duchy of Milan and the county of Pavia between his sons, and the restored duchy never rose again to its former power. ♦The eastern cities won by Venice, 1406-1447.♦ The eastern parts, Padua, Verona, Brescia, Bergamo, were gradually added to the dominion of Venice. By the middle of the fifteenth century, that republic had become the greatest power in northern Italy. ♦House of Sforza, 1450-1535. | Claims of the Kings of France, 1499-1525.♦ In the duchy of Milan the house of Sforza succeeded that of Visconti; but the opposing claims of the Kings of France were one chief cause of the long wars which laid Italy waste in the latter years of the fifteenth century and the early years of the sixteenth. The duchy was tossed to and fro between the Emperor, the French King, and its own dukes. Meanwhile the dominion which was thus struggled for was cut short at the two ends. ♦Cession to the Alpine Leagues, 1512-1513.♦ It was dismembered to the north in favour of the two Alpine Leagues, as will be hereafter shown more in detail. ♦The Popes obtain Parma and Piacenza, 1515. | Duchy of Parma and Piacenza, 1545.♦ South of the Po, the Popes obtained _Parma_ and _Piacenza_, which were afterwards granted as papal fiefs to form a duchy for the house of Farnese. Thus the Duchy of Milan which became in the end a possession of Charles the Fifth, and afterwards of his Spanish and Austrian successors, was but a remnant of the great dominion of the first Duke. The duchy underwent still further dismemberments in later times. ♦Land power of Venice only.♦
