Uncovering the hidden history of Islamophobia and its surprising connections to the long-standing hatred of Jews.Hatred of Jews and hatred of Muslims have been intertwined in Christian thought since the rise of Islam. In Jewish Muslims, David M. Freidenreich explores the history of this complex, perplexing, and emotionally fraught phenomenon. He makes the compelling case that, then and now, hate-mongers target "them" in an effort to define "us."Analyzing anti-Muslim sentiment in texts and images produced across Europe and the Middle East over a thousand years, the author shows how Christians intentionally distorted reality by alleging that Muslims were just like Jews. They did so not only to justify assaults against Muslims on theological grounds but also to motivate fellow believers to live as "good" Christians. The disdain premodern polemicists expressed for Islam and Judaism was never really about these religions. Rather, they sought to promote their own visions of Christianity-a dynamic that similarly animates portrayals of Muslims and Jews today.
