After 1795, the princes Lubomirski engaged in clandestine and insurgent activities against the occupying Russians; and, in consequence, they lost estates. Prince Jerzy Roman Lubomirski (1799 – 1865), the owner of Rozwadów, participated in the battles of the November and January uprisings and organized hospitals for the wounded on his estates. After the collapse of the uprising, his palace became a place where secret meetings of Polish patriots were held. Jerzy was active in social and scientific fields, maintaining a grammar school and poorhouse for the poor and establishing two scientific foundations, one funding the scientific testing of equipment, the other rewarding Polish authors of outstanding scientific works. His brother Adam Hieronim Karol Lubomirski (1811 – 1873) was awarded the Virtuti Militari cross, for participating in the November Uprising.
