This paper provides examples of conversion in the bourgeoning Zionist movement and early state of Israel, and will demonstrate that Zionism did not consistently maintain either ethnic or civic nationalism. Specifically this paper addresses cases of and discourse about intermarriage of Zionists and non-Jews who did not convert to Judaism. The first set of cases will be from the beginning, theoretical stages of the movement in Europe, when prominent Zionist leaders Israel Zangwill and Max Nordau married non-Jews. The second case is from Palestine several decades later, when a non-Jewish husband of a Jewish refugee from Nazi Germany joined the Haganah (and was later buried in a Jewish cemetery despite the fact he never converted). These examples, as well as the broader project on conversion and early Zionism as a whole, show how the Zionist case may (or may not) illumine the relationships between religion and nationalism in other nationalist cases.
