Although a fictitious state, I gradually filled up the history of Frundsberg.
Frundsberg was originally associated with the Hanseatic states and was an Imperial free town. It's prosperity was based on trade and manufacturing. Once the Frei Stadt was established the council of elected ministers acted as it's government. However the system of government was unusual as the number of votes per person was based an individuals payments to the Frei Stadt. Income for the Frei Stadt was derived from two main sources, tolls on goods and services provided by the city and the contributions by merchants and nobles.
Frundsberg is located on the banks of the river Rhine with good access to the sea and also into Central Europe and positioned on a natural communications hub.
During the TYW Frundsberg and its surroundings were spared the deprivations of much of Germany by the policy of the council to pay a contribution to whoever seemed threatening at the time and also enter into a treaty to provide them with goods and services. Of course, the businessmen of Frundsberg ensure that the margins on the business covered the cost of the contribution. The income stream was helped by the brothels and churches providing a mutually profit out of providing pleasure and absolution.
