Islamists in a Zionist Coalition: The Political and Religious Origins explores the decision made in 2021 by the United Arab List, the political arm of the Southern Branch of the Islamic Movement in Israel (SIM) to join the Israeli Zionist coalition for the first time, and specifically how and why it was possible for an Islamist movement to become the enabler of a Zionist government without losing the support of its religious scholars or political base. Through analyses of hundreds of books, columns, fatwas, media interviews, and posts on social media, as well as interviews conducted by the author with all the living leaders of the SIM and the United Arab List, Uriya Shavit demonstrates that the Islamic premises on which the SIM operates, rather than limit the party's flexibility, made it possible for the United Arab List to advance a pragmatic political agenda. This book argues that while the decision of the United Arab List to join a Zionist coalition led to dramatic consequences, it was grounded in decades of religious writings that prepared the ground for its legitimization, and aligned with a political orientation with which significant segments of the Arab population identified since the founding of the modern state of Israel.
