Elżbieta Sieniawska (ca. 1669–1729) led an active life and travelled extensively. She wrote a vast number of letters, analysed reports, newspapers and correspondence and personally handled her own legal matters. She played an important role in contemporary politics, while managing her large estates, where goods were manufactured, livestock bred, plants cultivated, precious ores extracted and crafts developed. She took care of her many residences, beautiful palaces surrounded by gardens, but also supported  various religious orders in the Polish-Lithuanian Commonwealth with her numerous foundations.
