The family estates often hired people from the lowest class, caring about their education, offering a place of residence, clothing, and a salary paid twice a year. For faithful service, workers were given ownership of land in perpetual or inheritable possession. Division The family, originally small in number, grew considerably, which led to divisions of material wealth but enhanced political influence, due to having the support of more people in the Sejms, in the Senate, or at the royal court. Members of the family were able to count on the support of their relatives in political or court activities.
