In 2013, just two years after the overthrow of Hosni Mubarak, the Egyptian military ousted the country's first democratically elected president, Mohamed Morsi of the Muslim Brotherhood. It's nothing new, argues Fawaz Gerges, who details how the clash between pan-Arab nationalism and pan-Islamism has shaped the history of the region from the 1920s to the present. Adding depth to a conflict that is poorly understood in the West, Gerges offers a dual biography of nationalist leader Gamal Nasser and the Muslim Brotherhood's Sayyid Qutb, the father of many branches of radical political Islam.
