Abstract This article examines the relationship between Conservative Judaism and Zionism, analyzing the movement's historical commitment to Jewish nationalism and its contemporary institutional development in Israel. Drawing on textual analysis of rabbinic sources and historical examination of organizational development, the study traces Conservative Judaism's Zionist orientation from its 19th-century origins through the establishment of Mercaz in 1978. The research methodology combines theological interpretation of classical texts with institutional history, particularly examining the delayed formal affiliation of Conservative organizations with the World Zionist Organization until 1977. Key findings indicate that despite individual Conservative Jews' prominent roles in Zionist leadership, the movement's collective institutional presence in Israel remained underdeveloped compared to Orthodox alternatives. The analysis identifies five unique contributions Conservative Judaism offers to contemporary Zionism: integration of Israel-Diaspora relations, creation of new Zionist ideology, synthesis of religion and peoplehood, promotion of religious pluralism, and integration of faith with social justice (tikkun olam). The study concludes that establishing authentic non-Orthodox religious alternatives in Israel is essential both for Israeli spiritual development and for validating Conservative Judaism's universal theological claims. The research demonstrates that effective Conservative Zionist engagement requires institutional planting rather than individual participation alone.
