This chapter examines efforts of Jews and Muslims in Morocco to reconcile communism with Moroccan nationalism predicated on Islam, centered on the figure of the King as the amir al-mu’minin (Commander of the Faithful) through the long 1960s. The stakes for Jewish and Muslim communists in this setting were high, including the need to demonstrate authenticity and legitimacy of their political movement in the face of accusations of communism as a foreign, colonial, and thus inorganic movement within Morocco. The long 1960s included a major leftist student uprising in 1965, several constitutional crises, and two attempted coups, all of which heightened the existential tension of the Moroccan left within the Islamist monarchy.
