Próba utworzenia gdańskiej faktorii handlowej w wielkim Księstwie Litewskim w XVII wieku

On October 30th, 1629 Krystyna, the wife of Janusz Kiszka, governor of Połock, entered into an agreement with Abraham Jonaszewicz, bourgeois from Gdańsk. It was a sale agreement of goods Czaśniki located in the provinces Połock and Vitebsk for 145 000 Polish złoty. Jonaszewicz represented a group of burghers from the city of Gdańsk who intended to create a trading post dealing with forest and agricultural products in the Grand Duchy of Lithuania. Czaśniki village was located at the Uła River, a navigable tributary of the Dźwina [Daugava] River. The river port of Czaśniki employed many villagers living on the shipping of goods to Riga city. The agreement on sale of the Czaśniki goods to Jonaszewicz was finally not concluded, probable because of the offer for the purchase of this property for a sum higher by 25 000 respectively, made by Jakub Hoffman, burgher of Vilnius. This time it was Hoffman who had not fulfilled the terms of the agreement, and Krystyna Kiszka, along with her husband Janusz, sold Czaśniki to Leon Kazimierz Sapieha. The transaction described in the article is the only one known attempt to create a trading post in the Grand Duchy of Lithuania by the people of Gdańsk.
