Egyptian vassal of the Ottomans, Muhammad Ali, and his son Ibrahim Pasha successfully broke away from Ottoman leadership and, conquering territory spreading from Egypt to as far north as Damascus, asserted their own rule over the area. The so-called Peasants' Revolt by Palestine's Arabs was precipitated by heavy demands for conscripts. The local leaders and urban notables were unhappy about the loss of traditional privileges, while the peasants were well aware that conscription was little more than a death sentence. Starting in May 1834 the rebels took many cities, among them Jerusalem, Hebron and Nablus and Ibrahim Pasha's army was deployed, defeating the last rebels on 4 August in Hebron. Benny Morris argues that the Arabs in Palestine nevertheless remained part of a larger national pan-Arab or, alternatively, pan-Islamist movement. Walid Khalidi argues otherwise, writing that Palestinians in Ottoman times were "[a]cutely aware of the distinctiveness of Palestinian history ..." and "[a]lthough proud of their Arab heritage and ancestry, the Palestinians considered themselves to be descended not only from Arab conquerors of the seventh century but also from indigenous peoples who had lived in the country since time immemorial, including the ancient Hebrews and the Canaanites before them." Zachary J. Foster argued in a 2015 Foreign Affairs article that "based on hundreds of manuscripts, Islamic court records, books, magazines, and newspapers from the Ottoman period (1516–1918), it seems that the first Arab to use the term "Palestinian" was Farid Georges Kassab, a Beirut-based Orthodox Christian." He explained further that Kassab's 1909 book Palestine, Hellenism, and Clericalism noted in passing that "the Orthodox Palestinian Ottomans call themselves Arabs, and are in fact Arabs," despite describing the Arabic speakers of Palestine as Palestinians throughout the rest of the book." Bernard Lewis argues it was not as a Palestinian nation that the Arabs of Ottoman Palestine objected to Zionists, since the very concept of such a nation was unknown to the Arabs of the area at the time and did not come into being until very much later. Even the concept of Arab nationalism in the Arab provinces of the Ottoman Empire, "had not reached significant proportions before the outbreak of World War I." Tamir Sorek, a sociologist, submits that, "Although a distinct Palestinian identity can be traced back at least to the middle of the nineteenth century (Kimmerling and Migdal 1993; Khalidi 1997b), or even to the seventeenth century (Gerber 1998), it
