Geography of Switzerland rolling hills and plains of the plateau. The smaller Jura Mountains are located on the north west side of the plateau. Much of the northern border with Germany follows the Rhine, though the Rhine enters Switzerland near Schaffhausen. The eastern border with Germany and a portion of Austria is drawn through Lake Constance (). A portion of the southwest border with France is drawn through Lake Geneva. Switzerland is divided into 26 sovereign cantons. The cantons along the Swiss Plateau tend to be the most populous, industrial and religiously Protestant. The cantons in the Alps tend to be less populous,
Historiography of Switzerland methods, and, following European trends, on the medieval period and the Reformation.

The early 20th century saw the publication of great topical histories of Switzerland, including Eugen Huber's legal history ("Geschichte und System des schweizerischen Privatrechts", 1893), Andreas Heusler's constitutional history ("Schweizer Verfassungsgeschichte", 1920; supplanted by Hans Conrad Peyer's "Verfassungsgeschichte" of 1978) and Paul Schweizer's diplomatic history ("Geschichte der schweizerischen Neutralität", 1895; continued by Edgar Bonjour from 1946 on).
