the Ottoman Empire in 1517. Afterward, Sultan Suleiman the Magnificent (r. 1520–66) transferred Tulkarm's waqf to the al-Jawhariyya Madrasa (Commons), located in the Muslim Quarter, northwest of the al-Aqsa Mosque. Under this arrangement, Tulkarm's inhabitants paid a third of their harvest as a tax towards the waqf, called qasm. At the time of the waqf'''s reassignment, the population of the village was estimated at 522 (95 households) and the qasm consisted of eight carats of wheat and three carats of barley. The town's elite families administered the trust, which enabled them to reach higher social and economic status. The population increased through intermarriage with families fleeing violent feuds between the various clans of Jabal Nablus. By 1548, the population had grown significantly to 189 households or roughly 1,040 persons. In 1596 Tulkarm appeared in Ottoman tax registers as being in the nahiya (subdistrict) of Qaqun, which was a part of the sanjak (district) of Nablus. The largest village in the nahiya, Tulkarm had a population of 176 Muslim households (roughly 968 persons) and paid taxes on wheat, barley, summer crops, olives, goats, beehives and a press for olives or grapes. During this early period of Ottoman rule, there were five neighborhoods (pl. harat) centered around the Shaykh Ali al-Jazri al-Mughrabi Mosque, today referred to simply as the "Old Mosque". The population was overwhelmingly Sunni Muslim, and most residents were fellahin (peasants who worked the land.) The elite families during that time were the Zaydan and the Lajjun-based Tarabay, the latter belonging to the Bani Harith tribe. Because of the decentralized nature of the Ottoman state, these families and their successors in later centuries ruled the area with a high degree of autonomy. The Zaydan had particular authority over Tulkarm, being appointed as the mutassalim (tax collectors or enforcers) on behalf of the central authorities. In the mid-17th-century most members of the Zaydan family, with the exception of the children and the elderly, were killed in a massacre by Tulkarm's inhabitants during Friday prayers. This was in reaction to the Zaydan having forced Tulkarm's residents to harvest and process the village's grains for taxation purposes. Consequently, political power in Tulkarm passed to the Badran clan, while the Fuqaha family took control of administering the "waqf" lands, firmly placing them as the village's religious leaders. The Fuqaha had derived much of their authority from their classification as "ashraf" and their association with
