Baruch Kimmerling and Joel S. Migdal consider the 1834 Peasants' revolt in Palestine as constituting the first formative event of the Palestinian people. From 1516 to 1917, Palestine was ruled by the Ottoman Empire save a decade from the 1830s to the 1840s when an 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 "aware of the distinctiveness of Palestinian history ..." and "[although 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."
