Following the adoption of the Ottoman Land Code in 1858, the "musha" (collective landownership) system was gradually abrogated and residents were required to register their property with the central authorities. The fellahin were wary of registering their names for fear of military conscription by the Ottoman state and instead entrusted various elite clans with the role of landlords, who were in effect absentee owners. This altered the area's social structure, with the Samara, al-Hajj Ibrahim and Hanun clans legally obtaining vast swathes of Tulkarm's lands. Leadership of the town's two main religious establishments were generally supplied by the Kur-based Jayyusi clan and the al-Barqawi clan of Shufa. The Barqawi clan controlled the area around the town in the 19th century.
