Long before the original articles of the confederacy, the alliance of the three Forest Cantons of Dec. 9, 1315, were concluded, the highways over Mt. Gotthard had become the channels of an active commerce between Germany and Italy. When they were opened for this purpose cannot be clearly shown, but they were certainly so used in the twelfth century. The inhabitants of Uri, and partly also those of Schwytz and Unterwalden supplied the Italian markets with their cattle, and the mountain-valley of Urseren flourished particularly by means of this trade. But they had dangerous neighbors in the turbulent Lavinians on the south side of Gotthard. Here the Swiss and Italians met each other in hostile attitude at an early period; for the first time, as far as we know, in the year 1331. The Lavinians had plundered some merchants on their way to Switzerland, as well as harrassed the people of Urseren who drove their cattle to Bellinzona. They were supported in this course by their landlords, the Visconti, Dukes of Milan. Uri called on Schwytz and Unterwalden for help, and on Zurich also, although it was not then included in the confederacy. The allies marched out and pressed on to Faido, spreading universal terror. The General Vicar of Como mediated a peace; but from that time forth we find the confederates continually entangled in the affairs of Upper Italy. Campaigns of a greater or less extent are undertaken, and treaties struck, broken, and again renewed. The chief business seems to have been the settlement of boundaries. Perhaps it would have been better, if all that lay on the further side of Gotthard and the Bundtner Alps had remained without any direct communication with Switzerland. There is too wide a difference between the Italian and the German character. But the struggle to secure for their chief products an advantageous market had greater weight with the three shepherd cantons. Sustained by their confederation they soon endeavored, sword in hand, to extend their boundaries southward, and in 1476 Livinen came under the acknowledged sovereignty of Uri, and in 1500 Bellinzona with the adjoining country under that of the Three Cantons. In 1503 these changes were confirmed by France, which then had the upper hand in Lombardy.
