烏里州
Between 1403 and 1422 some of these lands were annexed by forces from Uri, but subsequently lost after the Battle of Arbedo in 1422. While the Battle of Arbedo stopped Swiss expansion for a time, the Confederation continued to exercise influence in the area. The Canton of Uri conquered the Leventina Valley in 1440. In a second conquest Uri, Schwyz and Nidwalden gained the town of Bellinzona and the Riviera in 1500. The third conquest was fought by troops from the entire Confederation (at that time constituted by 12 cantons). In 1512, Locarno, the Maggia Valley, Lugano and Mendrisio were annexed. Subsequently, the upper valley of the Ticino river, from the St. Gotthard to the town of Biasca (Leventina Valley) was part of the Canton of Uri. The remaining territory ("Baliaggi Ultramontani", "Ennetbergische Vogteien", the Bailiwicks Beyond the Mountains) was administered by the Twelve Cantons. These districts were governed by bailiffs holding office for two years and purchasing it from the members of the League.
