The American University of Beirut has long been regarded as a crowning jewel of American education in the Middle East while also a hub of Arab nationalism and cultural identity. Among its diverse student body in the first half of the 20th century were hundreds of Jews who arrived at AUB from Europe and the Middle East, including European immigrants to Palestine. This paper traces the experiences of these Jewish students – who constituted about 10 percent of the student body – at a time of rising Arab nationalist sentiment on campus, a growing Zionist movement worldwide, and mounting Jewish-Arab violence in Palestine. In what ways did Jewish students at AUB engage with these nationalisms? How did rising tensions in Palestine affect their interactions with fellow students? I focus on three spheres of interaction: intra-Jewish relations; inter-religious encounters; and transnational networks. Through analysis of AUB annual reports, student journals, newspaper articles, memoirs, and photographs, this research builds on excellent recent scholarship on AUB, Arab nationalism, Jews in the Arab world, and Jewish-Arab relations. It seeks apply the ‘relational’ approach used by historians of Palestine to shed new light elsewhere on Jewish-Arab encounters in the early 20th century.
