family is closely linked with the rulers of the Piast dynasty. One of the Szreniawici was a canon at the Wawel court, and people using this coat of arms belonged to the inner circle of Bolesław Śmiały, according to Jan Długosz, in Annals or Chronicles of the Famous Kingdom of Poland (Roczniki czyli Kronikisławnego Królestwa Polskiego). The oldest document mentioning the Lubomirski family comes from the 11th century. It is in the property section of the Crown Register of 1682 in Kraków. The original no longer exists. There is only a mention in the register under a given year. Successive members of the family took up positions of bishops, for example, Piotr, Archbishop of Gniezno mediated between the princes of the Piast dynasty during the congress in Łęczyca in 1180. The family performed important functions at the court of the Piast dynasty and extended their estates through investing in land, mainly within the territory of the Małopolska province. Jakub Lubomirski served as a borough writer in the 14th century. Foundations of economic power Piotr (d. 1480), the heir of Lubomierz, the territorial designation that is the basis of the family name, is regarded as the progenitor of the Lubomirski family. The economic foundation of the family rested on the exploitation of salt mines in Kraków province, the mineshafts being leased from rulers of Poland. The Lubomirski family also established private mines in Małopolska province. Sebastian (c. 1546 – 1613), who in 1581 became a mine administrator of Kraków, was the creator of this economic power. This was the first administrative position in the capital city occupied by a member of the family. While taking up his duties, Sebastian had the support of Stefan Batory. In 1595, Sebastian received the title of Count of Wiśnicz from the Emperor Rudolf II; in 1591, he entered the Senate as governor of Małogoszcz. He opened a private salt mine shaft "Kunegunda" in Siercza, which was exploited for about 100 years. Money gained from the salt trade allowed the Lubomirski family to lend money to even the wealthiest people in the country. This enabled them to purchase properties or take them over from insolvent debtors. The family built up its economic position over many generations, accumulating assets that they held for centuries.
