In order to finance all the different enterprises, which were often poorly supervised, Tyzenhaus needed to borrow vast amounts of money. He relied on the expensive expertise of educated foreign industrialists; efforts to build a local class of workmen were hampered by the poor education system and serfdom. Tyzenhaus' influence on the King and attempts to manipulate the lesser nobility raised political opposition among other nobles. After a few failures of his factories, in 1780 nobles brought charges that Tyzenhaus used treasury money for his private affairs. The case against Tyzenhaus was arranged by Otto Magnus von Stackelberg, the Russian ambassador in Warsaw. Tyzenhaus was relieved of his duties by Poniatowski; his privileges were revoked and his property was confiscated. Disgraced, Tyzenhaus died in 1785 in Warsaw.
