Jews were part of a very complex system, which were old Polish urban organisms. Living in the city, they did not belong to the community of burghers, but they functioned in it as representatives of a separate state subordinated to royal officials. They were at best tolerated by the burghers, who saw them as dangerous economic rivals. However, the nobility and the clergy perceived their presence as a source of income augmentation. This applies especially to the Jewish leaseholders, whose businesses were as much profitable as controversial towards the divergence of interests of different groups forming the urban organism. It can be illustrated with an example of several cities where the Jewish leaseholders appeared in the late eighteenth century as representatives of the economic interests of mayors, monasteries and parish priests, and also magistrates.
