History The basis for the postal organization was the trading postal service, which derived from the merchants' need to communicate on commercial matters. These merchants were from Germany, and later on also from Italy, therefore most active relationships were maintained with them. In the 14th and 15th centuries Cracow was communicating with German towns through messengers, who were remunerated by commercial confraternities. The best designed trading post of this type was owned by the Fugger family who at the end of the 15th century established their factories in Cracow. Initially they were used for the trade of copper. With time, though, they started to also deal with financing operations. The Fugger Post was primary used only for the maintenance of communications between these factories and the central office in Augsburg. In later years, its services were used by the king Sigismund I of Poland, the queen Bona Sforza and the vice-chancellor Piotr Tomicki. The second serious trading postal service was the Seweryn Boner's post. Boner's banking house kept permanent agents who facilitated the forwarding of the correspondence of private persons.
