"God's Crucible" is Pulitzer-Prize winning scholar David Levering Lewis's contribution to the ever-growing body of literature that seeks a better understanding of Islam and the roots of its long and complicated struggle with the west. Unlike other scholars of Islamic and Middle Eastern history who have dashed off books in the wake of September 11 -- Bernard Lewis (whom the author consulted) and Michael Oren are among the best known -- Levering Lewis's prior books have focused on Martin Luther King Jr, W.E.B. DuBois, and the leaders of the Harlem Renaissance. This gave Lewis a fresh perspective in writing "God's Crucible" as he was not burdened by what he might have written in earlier books. Still, it is clear that Lewis himself did not really know where his research would take him, what his main points would be, or even what to call this book before he started (a friend, Sandra Masur, suggested the eventual title, "God's Crucible"). With that said, this is a useful and thoughtful book.
"God's Crucible" refers to al-Andalus, or Muslim Spain, as the site of the first clash of civilizations between Islam and the Christian west. Lewis's "God's Crucible" emphasizes three major themes: (1) the rise of Islam was enabled by perpetual conflict between the Roman Empire and the Iranian Empires (Parthian, Sassanian, Persian); (2) Islam and its Caliphates almost immediately were infected by the inevitable power struggles that plague all such institutions, and even in the so-called glory-days of the first Caliphate, Islam was not monolithic; and finally (3) coexistence between Islam and Christianity in al-Andalus (if not entirely peaceful) engendered the transmission of knowledge and ancient texts from the more-advanced civilization of the caliphs in the east to the backward, medieval Christians of Europe.
The first theme is that the centuries-old imperial struggle between Latin Rome and Persian Iran created the conditions for the disunited Arab tribes living in the deserts of Arabia to unite, found a new religion, and create a greater Islamic Empire. This "Caliphate" subsequently encompassed Arabia, all of modern Iran, and stretched west across North Africa to the pillars of Hercules and north into Europe up to the Pyrenees. Perpetual conflict arguably began in 53 BC when Marcus Crassus infamously brought an invasion force across the Euphrates River Valley. Crassus's expedition met with disaster at Carrhae, resulting in his own destruction and that of seven legions. The Roman Emperors never entirely lost their thirst for expansion into the east however, and Emperors such as Trajan, Severus, Justinian, Constantine, and Heraclius would all bring armies into the fertile crescent in an effort to subdue this troublesome region. This perpetual warfare fatally weakened both the Roman and Persian Empires to the point that although Khosrow II of Persia had thought he won a decisive victory in Jerusalem in 615 AD by bringing back the relics of the Holy Cross, his victory was largely Pyrrhic. A new force led by Muhammad was emerging from the barren sands of Arabia.
Muhammad was born in Mecca, a small town on a popular Roman trade route, in 570 AD. In the month of Ramadan in the year 610, the 40-year old Muhammad began to hear messages from God that he spread to others through his teachings. By the time he died in 632 AD, Muhammad had united all of the tribes of Arabia into a powerful military force that rapidly expanded into the vacuum left by the militarily exhausted Roman and Persian Empires. Riddled with internal decay, the Persian Empire was soon swept away by Islamic forces while these same forces concurrently spread like wildfire across formerly Roman North Africa and into Spain. By 711 AD, Islamic Armies had advanced into and established a firm foothold in Spain, or al-Andalus. But this newly created Islamic Empire was hardly united.
Lewis's second theme is that Islam itself was never monolithic, and that while the caliphs did not distinguish between church and state, both church and state suffered major cleavages early in the first Caliphate. Almost immediately after Muhammad's death, conflict arose over who his legitimate successors should be. One faction argued that it should be Muhammad's familial descendants, who became the Shi'ites, while another faction thought the community of the faithful should choose their own rulers to follow Muhammad, who became the Sunnis. These factions remain locked in perpetual conflict to this day. On the state side, the Umayyad caliphs ruled from 711-750, but suffered defeat at Poitiers (in southern France) in 732. While not catastrophic, this defeat weakened the Umayyads at a time when they were also plagued with rebellion from the North African Berbers. The Abbasids eventually took advantage of this Umayyad weakness and overthrew the caliphate, establishing their own in 750 and moving its capitol from Damascus to Baghdad. But this story gets more complicated. An incredible 19-year-old Umayyad named Abd al-Rahman I escaped from certain death in North Africa into al-Andalus, eventually establishing a power base there that enabled him to rule for 25 years. Nicknamed "The Falcon" for his cunning, and with survival being the mother of all necessity, Rahman I cooperated with Christians to defeat Abassid armies dispatched to bring him to heal. With these dynamics at play, the conditions were created in al-Andalus for Islamic and Christian coexistence in "God's Crucible."
This brings us to Lewis's third theme: that important knowledge from the center of Islamic civilization in Baghdad made its way across North Africa, onto the "conveyor belt" of Toledo, and into Christian Europe. Lewis argues that this knowledge provided critical building blocks for the Renaissance and western awakening centuries later. He also seems to lament how the Christian response to jihad, which became officially sanctioned Holy War, gradually erased the "middle ground" that had existed in al-Andalus that allowed the transmutation of such valuable knowledge. al-Andalus deteriorated into extremism on both sides. In this lament, he seems to be speaking directly to the modern world of the dangers and lasting harm caused by extremism.
In conclusion, this is a useful and thoughtful book that sheds much-needed light on a period of history that is rarely examined or understood. The book contains abundant maps, a glossary of terms, and a genealogy of both Muslim and Christian rulers. Still, I would hesitate to recommend this book to everyone as it often wanders a field, is dense with difficult names and places, and reads as if it were written for an academic rather than a general audience. Lewis himself says that this project started out as a small book that became a large one, and the reader is left to wonder if the abundance of Lewis's research and the complexity of his subject caused him to write a book that surpasses the reach of those he likely intended it for. In a larger scope though, "God's Crucible" is an important contribution to understanding Islam's long struggle with the Christian west, which is a topic that will remain with all of us for some time.
