Although the economic and industrial progress occurred rapidly, most of the farms, called "folwarks", chose to rely on serfs and paid workforce. Only a few have experimented by obtaining proper machinery and plowing equipment from England. New crops were being cultivated like sugar beet, which marked the beginning of Polish sugar refineries. The use of iron cutters and plows was also favoured among the farmers. During the January Uprising the occupying authorities sought to deprive peasant insurgents of their popularity among landed gentry. Taxes were raised and the overall economic situation of commoners worsened. The noblemen and landowners were, on the other hand, provided with more privileges, rights and even financial support in the form of bribery. The aim of this was to weaken their support for the rebellion against the Russian Empire.
