Although Acre and the Galilee were part of Sidon Eyalet while the rest of Palestine administratively belonged to Damascus, it was the rulers of Acre, beginning with Zahir, that dominated Palestine and the southern Syrian districts. Damascus governors typically held office for short periods of time and were often occupied with protecting and leading the Hajj caravan (the office of "amir al-hajj" had become the responsibility of the Wali of Damascus in 1708), preventing them from asserting their authority over semi-autonomous areas such as the Nablus region. In contrast, Zahir established Acre as a virtually autonomous entity, a process seen in other parts of the Ottoman Empire including Egypt, Mount Lebanon and Mosul. Moreover, Acre became the "de facto" capital of Sidon Eyalet during and after Zahir's reign, and like Zahir, his successors ruled Acre until their deaths. There were several military confrontations between Zahir and the Jarrar clan starting in 1735 when the former occupied the latter's territory of Nazareth and the Jezreel Valley, which served as trade and transportation hubs. Meanwhile, in 1766, the Tuqan family had ousted the Jayyusis from the Bani Sa'b subdistrict, which was then occupied by Zahir in 1771, stripping Nablus of its sea access. The conflict between Zahir and the Tuqans culminated with the former's unsuccessful siege of Nablus later that year.
