The author outlines a basic framework for anarcho-capitalism, a stateless social order in which safety, law and adjudication of disputes are provided by private companies (private defense agencies) competing with each other in the free market. In the course of presentation, three fundamental problems of anarcho-capitalism are addressed. (1) Is a peaceful cooperation among agencies possible? (2) Would agencies respect the rights of their customers? (3) How would the law look like in an anarcho-capitalist society? The last problem is especially vexing, since anarcho-capitalists seem to be caught up in a contradiction here. On one hand they are proponents of a specific moral theory (based on non-aggression principle), on the other hand they do not allow for any central, monopolistic agency to impose that moral theory on society. Is it possible for the law in the anarcho-capitalist society to be simultaneously produced by competing agents and remain libertarian at the same time?

The reign of Bolesław I the Brave has for many years been very popular among historians and numismatists. The political history of his rule is at the centre of the research of the first one, and the history of his coinage of the latter. On the other hand, much less attention is paid to the fiscal and prestigious-symbolic contexts of the circulation of bullion, which at the turn of the 10th and 11th centuries consisted almost exclusively of imported coins and silver in a non-monetary form, mainly jewellery. This raises many questions: how did access to luxury goods affected the exercise of power? What equivalents and under what circumstances were foreign coins purchased? How did the desire to take control of the silver distribution networks between Meissen, Prague and Kiev in the first decades of the 11th century directed Bolesław’s expansion? Methodologically, the article combines the analysis of the hoards with the interpretation of written sources.
