The Foundations of Zionism chronicles Zionism’s development from its early origins up to the establishment of the British mandate over Palestine in 1923, refuting many of the movement's own foundational myths. Sabri Jiryis delves into Zionism's successive congresses and factional struggles, its early failures to settle in Palestine and the formation of armed militias, and its temporary alliances with the Ottoman Empire before the movement eventually secured support from Western colonial powers such as Britain. In a newly written conclusion, Jiryis reconsiders the Zionist project 100 years on from the Balfour Declaration and amid the ongoing genocide in Gaza.
