which the family also possessed in the 13th century, increased significantly. In the 17th and 18th centuries they were located in Lubomierz, Nowy Wiśnicz, Bochnia, Wieliczka, Łańcut, Baranów Sandomierski, Puławy, Rzeszów, Równe, Tarnów, Jarosław, Przeworsk, and Janowiec upon the Vistula, among others. To this day, the castle in Nowy Wiśnicz has been the property of the Family Association of the Princes Lubomirski. Many estates were located in the territories of the largest Polish cities: Warsaw (e.g. Mokotów, Ujazdów, Czerniaków), Kraków (Wola Justowska, Kamienica Pod Baranami), Rzeszów (castle), Sandomierz, and Lvov. Maintaining foreign residences in Drezno, Vienna, and Paris enhanced family prestige. The members of the family were referred to as "the owners of the bank of the Dnieper River" because many of their estates were located in what is now Ukraine and Slovakia. The Lubomirski family enjoyed political, military, and economic influence, which was concentrated in the provinces of Kraków, Sandomierz, Stanisławów, and Ruthenia, to eventually cover the whole area of the Commonwealth of the Two Nations. They kept this state of ownership until the collapse of the Polish state, when they were deprived of many estates as a result of penalties for pro-independence activities. The Lubomirski family looked to invest by buying large estate complexes. They consciously strived to gather them into one contiguous whole. Territorial expansion began in the ancestral territory located south of Kraków and was directed toward the east. The combined estates reached their largest size at the time of Stanisław (d. 1649). It was the third largest holding in the Republic of Poland, only smaller than the entail of Ostróg and the estates of the Radziwiłł family. In addition to purchasing properties, the Lubomirski family leased rich royal estates, such as the Starosties of Spisz, Sandomierz, and Sącz. Income from the land leased from the king was comparable to that from private estates. The family introduced several innovative facilities and processes to their estates. Their arable farms adopted methods of industrial production; sugar factories, distilleries, and factories were built. They also introduced enlightened social practices, such as granting equal rights for subjects, allowing Jews to buy properties in private towns and to build houses, and vesting them with judicial powers. Jerzy Sebastian was particularly involved in the activities of democratization. He believed that the increase in economic rights of all his subjects would make him get richer, too.
