Foundation and First Mentions
The history of Kassel is rooted in the early Middle Ages. The settlement was first mentioned in official documents in 913 AD under the name Chassalla (or Chassella). At that time, King Conrad I signed two deeds here, indicating the existence of a fortified royal court at this location. The name likely derives from the Latin Castellum (fortress) or a Frankish term denoting a fortification on the river.
Key Factors of Formation
The transformation from a small fortification into a prosperous city was driven by several important factors:
- Geography and Logistics: The city emerged on a strategically important elevation near a crossing over the river Fulda. This location allowed for the control of the movement of goods and people in the region.
- Political Power: A decisive moment was the rise of Kassel as an administrative center. In the 12th century, it came under the rule of the Landgraves of Thuringia, and after 1277, it became the main residence of the Landgraves of Hesse, securing the city's status as a capital.
- Acquisition of Rights: Around 1189, Kassel received town rights, which provided a legal basis for the development of self-government, the construction of walls, and the organization of markets.
Early Cultural and Economic Features
The economy of early Kassel was formed around serving the rulers' court and trade. Obtaining city status allowed for regular fairs to be held, attracting merchants and artisans. By the 13th century, the city was divided into several quarters and protected by powerful fortress walls. The cultural life of that time was closely linked to religious institutions, particularly the Ahnaberg monastery, founded in the early 13th century, which played a significant role in the spiritual and educational development of the region.
