The Zoudenbalch family (also known as Soudenbalch) was one of the most prominent families of Utrecht throughout the Middle Ages to the age of the Dutch Revolt. They occupied all posts of importance in the city government, possessed various lordships in the vicinity and played a leading role in the history of the Sticht (Prince-Bishopric of Utrecht). The Zoudenbalchs were also Lords of the island of Urk in the Zuiderzee (now IJsselmeer) for over a century (1476–1614), and as such played a key role in the life of that community during troubled times in the 16th century.
