Uri, one of the four forest cantons of Switzerland, lying south of Schwyz and east of Unterwalden, with which two it combined to form the original Swiss Confederation. The area is 422 square miles, and consists mostly of mountain and forest, with some arable land along the course of the Reuss. Mount St. Gothard overshadows the southern border, and to the west runs the main range of the Alps. Altorf is the capital. In 1799 it was the theatre of war between the French and Austro-Russian allies. The lake of Uri, the S.E. portion of that of Lucerne, has very precipitous shores, and receives the waters of the Reuss.
