The Canton of Zug (German Kanton ) is one of the 26 cantons of Switzerland. It is located in central Switzerland and its capital is Zug. With 239 km² the canton is one of the smallest of the cantons in terms of area. It is not subdivided into districts. It is the economical centre of Central Switzerland.
The earlier history of the canton is practically identical with that of its capital Zug. From 1728 to 1738 it was distracted by violent disputes about the distribution of the French pensions. In 1798 its inhabitants opposed the French. The canton formed part of the Tellgau and later was one of the districts of the huge canton of the Waldstätten in the Helvetic Republic. The canton of Waldstätten also consisted of what is today the Canton of Schwyz, the Canton of Lucerne, Unterwalden and the Canton of Uri.
In 1803, in the Act of Mediation, the canton of Zug regained its independence as a separate canton. The constitution of 1814 abolished open assemblies (Landsgemeinde), which had existed in the canton since 1376. In 1845 the canton of Zug became a member of the Sonderbund and shared in the war of 1847 which was lost to the Swiss confederation. In 1848 the remaining functions of the open assemblies (Landsgemeinde) were abolished. Both in 1848 and in 1874 the canton voted against the federal constitutions. The constitution of 1876 was amended in 1881, and replaced by a new one in 1894.
Near the southern shore of the lake of Ägeri is the site of the famous Battle of Morgarten, won by the Swiss in 1315. In this battle the powerful Habsburgs were defeated. The hamlet of Morgarten (Municipality of Oberägeri) borders the Canton of Schwyz and is home to the Morgarten Battle Monument (Morgarten Denkmal). The actual battle ground is just across the border in the hamlet of Schornen (Municipality of Sattel) in the Canton of Schwyz.
