Abstract The history of the Jews of Lebanon is often overlooked—they are considered victims of the Arab–Israeli conflict, or within the context of the wider Levantine Jewish community. Sidon, a port city of biblical origins, is a distinct case study through which to examine the interplay between Zionism and Lebanese nationalism because of Sidon’s historical background, geographic proximity to Palestine, and subordinate position to the Beiruti Jewish community. I show how the Israelite Community Council operated within a contested national-ethnic sphere, where it effectively straddled the Zionism promoted by members of the Yishuv and the emerging Lebanese nationalism of the newly established Grand Liban. Initially seeing itself as part of the Land of Israel/Eretz Israel, the Jewish community of Sidon asserted itself within the multiconfessional Lebanese state. Sitting at the crossroads of competing ethnonational currents, Sidon’s Jewish community leaders espoused a fluid, local-territorial-based identity, one that was at ease both with Jewish and Lebanese nationalism. We expand our understanding of this now dispersed community through an examination of the evolution of national borders, intercommunal relationships, and engagement with the Yishuv.
