Duty on goods is one of the oldest public taxes to be levied on Polish soil by ”state au- thorities”. The duty during the reign of the Piast served a purely fiscal purpose and provided reigning monarchs with a primary source of revenue. In the early Middle Ages it possessed the character of the duty charge we are all familiar with. Absorbed in the chambers of Customs (toll – may have been the name used) collection points were not only located at the country’s external borders, but also internally.
