Prince Andrzej Lubomirski, the second entailer of Przeworsk, was not only a literary supervisor of the National Ossoliński Institute in Lviv but also an entrepreneur and founder of one of the first sugar factories in Galicia. In the interwar period he struggled with a lot of problems related to the economic situation in the newly independent Poland. Through abusing his plenipotentiary powers, Prince Andrzej’s son, Jerzy Rafał Lubomirski, put the Przeworsk Entail as well as the “Przeworsk” Małopolska Sugar Company in considerable debt. His fault was also the loss of the controlling interest in the sugar company in favour of the Sugar Bank in Poznań. The Przeworsk entailer had also come into conflict with his brother due to financial issues. However, despite those problems, Prince Andrzej Lubomirski was still actively engaged in the matters of industry and it was thanks to him that the “Przeworsk” sugar factory was modernized and the “Horodenka” sugar factory built. The outbreak of World War II thwarted his plans to repay the debts and pursue further initiatives.
