William Tell (German: Wilhelm Tell, German pronunciation: [ˈvɪlhɛlm ˈtɛl]; French: Guillaume Tell; Italian: Guglielmo Tell; Romansh: Guglielm Tell) is a folk hero of Switzerland. According to the legend, Tell was an expert mountain climber and marksman with a crossbow who assassinated Albrecht Gessler, a tyrannical reeve of the Austrian dukes of the House of Habsburg positioned in Altdorf, in the canton of Uri. Tell's defiance and tyrannicide encouraged the population to open rebellion and a pact against the foreign rulers with neighbouring Schwyz and Unterwalden, marking the foundation of the Swiss Confederacy. Tell was considered the father of the Swiss Confederacy.
