Iran is a land of contradictions. It is an Islamic republic, but one in which only 1.4 percent of the population attend Friday prayers. Iran’s religious culture encompasses the most censorious and dogmatic Shi’a Muslim clerics in the world, and yet its poetry insistently dwells on the joys of life-wine, beauty, sex. Iranian women are subject to one of the most restrictive dress codes in the Islamic world, but make up nearly 60 percent of the university student population. In A History of Iran, a leading expert on Iran chronicles the rich history of this complex nation from the Achaemenid Empire of sixth century B.C. to the present-day Islamic Republic.
