The present article aims to uncover the different meanings attached to land ownership in Palestine during the late Ottoman and British Mandate eras and to show how a `modern' understanding of ownership was imposed on the local population, particularly the fellahin (peasants), without a consideration of their needs and traditions. Many widespread claims are challenged, first and foremost the one according to which, at the time of the partition of Palestine (1947), `over 70 percent' of it did not `legally' belong to the local Arab majority, but to the British Mandate power, an assumption that has had political, cultural and social ramifications that have lasted until the present day.
