The history of the city of Bern proper begins with its founding by Duke Berchtold V of Zähringen in 1191. Local legend has it that the duke vowed to name the city after the first animal he met on the hunt, which turned out to be a bear. Both the name of the city (Bern can stand for Bär(e) n, bears) and its heraldic beast, come from this legend. At that time, much of today's Switzerland (then considered part of southern Burgundy) was under the authority of the house of Zähringen. The Zähringer leaders, although with no actual duchy of their own, were styled dukes by decree of the German king and exercised imperial power south of the Rhine. To establish their position there, they founded or expanded numerous settlements, including Fribourg (in 1157), Bern, Burgdorf and Morat
