History of Origins: From Settlement to City
Although archaeological finds indicate a Roman presence in the region (the ancient settlement of Petinesca), the history of modern Biel/Bienne as a full-fledged city begins in the Middle Ages.
Founding and First Mentions
The city was officially founded between 1225 and 1230 by the Prince-Bishop of Basel, Heinrich von Thun. The name Belna appears in documents as early as the mid-12th century. The Bishop initiated the construction of a castle and city fortifications to protect his holdings on the southern border, which served as the starting point for transforming a small settlement into a fortified town.
Key Factors of Development
- Geography and Strategy: Its location at the foot of the Jura mountains and on the shores of Lake Biel made the city an important strategic point. It controlled mountain passes and waterways connecting different parts of the region.
- Political Power: Biel was created as an administrative and military stronghold of the bishopric, designed to contain the growing influence of neighboring feudal lords, particularly the Counts of Neuchâtel.
- Trade and Rights: Obtaining city privileges allowed for the organization of markets and the collection of tolls, which contributed to a rapid influx of artisans and merchants seeking protection within the city walls.
Early Cultural and Economic Characteristics
Even in the early stages of its history, Biel/Bienne began to acquire the traits of a unique linguistic zone at the crossroads of German and French cultures, which defined its future status as a bilingual city. In its early centuries, the economy was primarily based on viticulture, fishing, and agriculture. A significant milestone was the conclusion of an alliance ("combourgeoisie") with Bern, which allowed the city to maintain a certain level of autonomy from the bishop and develop traditions of local self-government.
