Summary: Trading guilds, regulated under the norms of the Dubrovnik Statute, were known under the names entega, collegantia and rogantia. The first one was an association of labour, capital and funds for carrying out business activities, the second one stood on the cross-road between the trading dealings and enterprising ventures, while the third one was, in actual fact, a form of intermediation. Some of their forms are recognised also in the legal systems of the other Adriatic communes, but the best developed regulating norms prevailed in Dubrovnik. It was there that the original forms of association, adopted from the Byzantine practice and law, found a fertile ground for further expansion. The most complex form of these associations, the entega, was not to be found after the 16th century, while collegantia gradually ascended into a limited partnership society, i.e. into the crediting business.
