Flags and arms of cantons of Switzerland is a design by Paul Boesch, dated to 1943. The crozier symbolizes the former Prince-Bishopric of Basel, the seven stripes represent the seven districts of the Bernese Jura. It was officially recognized as a regional flag by Bern from the early 1950s. The canton of Jura was created in 1979 after a referendum, but only three of the seven districts opted to join. The seven stripes were retained in the cantonal flag regardless, and there remains some irredentism calling for a restored unity of all seven districts.

Historiography of Switzerland methods, and, following European trends, on the medieval period and the Reformation. The conservative Roman Catholic cantons – who had been defeated in the 1847 Sonderbund war – also received little attention from scholars situated in the liberal Protestant mainstream of the time. 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).
