The past sometimes provides examples of glory and success that serve as models. Other times, as the philosopher George Santayana said, it warns of impending calamity for those who do not learn from it.
For the past several years, I've been immersed in a history that does both. As one of the producers for an upcoming PBS documentary on the rise and fall of Islamic Spain, I've witnessed its amazing ascent and tragic fall countless times in the editing room, only to go home and watch some of the same themes playing out on the nightly news.
Islamic Spain lasted longer than the Roman Empire. It marked a period and a place where for hundreds of years a relative religious tolerance prevailed in medieval Europe.
A model for religious tolerance
At its peak, it lit the Dark Ages with science and philosophy, poetry, art, and architecture. It was the period remembered as a golden age for European Jews. Breakthroughs in medicine, the introduction of the number zero, the lost philosophy of Aristotle, even the prototype for the guitar all came to Europe through Islamic Spain.
Not until the Renaissance was so much culture produced in the West. And not until relatively recent times has there been the level of pluralism and religious tolerance that existed in Islamic Spain at its peak. Just as the vibrancy and creativity of America is rooted in the acceptance of diversity, so was it then.
Because Islam's prophet Muhammad founded his mission as a continuation of the Abrahamic tradition, Islamic theology gave special consideration to Jews and Christians. To be sure, there were limits to these accommodations, such as special taxes levied on religious minorities. But in the early Middle Ages, official tolerance of one religion by another was an amazingly liberal point of view. This acceptance became the basis for Islamic Spain's genius. Indeed, it was an important reason Islam took hold there in the first place.
When the first Muslims crossed the straits of Gibraltar into Spain, the large Jewish population there was enduring a period of oppression by the Roman Catholic Visigoths. The Jewish minorities rallied to aid the Arab Muslims as liberators, and the divided Visigoths fell.
The conquering Arab Muslims remained a minority for many years, but they were able to govern their Catholic and Jewish citizens by a policy of inclusiveness. Even as Islam slowly grew over the centuries to be the majority religion in Spain, this spirit was largely, if not always perfectly, maintained.
Pluralistic though it was, Islamic Spain was no democracy. After years of enlightened leadership, a succession of bad leaders caused the unified Muslim kingdom to fragment among many smaller petty kingdoms and fiefdoms.
Though they competed and fought, the spirit of pluralism continued. Indeed, it thrived as rival kings sought the best minds in the Muslim, Christian, and Jewish worlds for their courts. This was just as true in the Christian petty kingdoms, as the Muslim ones. Christian and Muslim armies even fought alongside each other against mutual rivals of both faiths.
It is at this point that the darker parallels to our time begin. Into the competition for land, resources, and power, some leaders on both sides began to appeal to religion to rally support for their cause. Wars became increasingly religious in nature. Into this tinderbox a match was thrown: the Crusades – the same term that many Arabs use today when referring to America's adventure in Iraq.
The Crusades deepened Spain's religious divide. Minorities in both Christian and Muslim kingdoms become increasingly suspect. Persecutions, expulsions, and further warfare ensued. Nothing could stop it, not even the black plague.
Ultimately, Christian kingdoms gained the upper hand as the Muslim kingdoms of Islamic Spain fell. Spain's Muslims and Jews were forced to either leave or convert. This led to the rise of the Inquisition, whose purpose was to verify the loyalty of suspect converts. The expulsions and inquisitions racked Spain economically, culturally, and morally. Its power was severely compromised. The fall of pluralism in Spain was the fall of Spain itself.
Dark parallels with today
This fall directly links to events today and raises many of the same stakes. Though few Americans note it, one of Osama bin Laden's justifications for the 9/11 attacks was to avenge the "tragedy" of Islamic Spain.
So far, the post-9/11 world and the policies it has spawned seem to be heading in the same dangerous direction as witnessed before. The religious intolerance that engulfed and overwhelmed medieval Spain threatens the increasingly beleaguered pluralism of our own time.
At its best, the history of Islamic Spain is a model for interfaith cooperation that inspires those who seek an easier relationship among the three Abrahamic faiths. At its worst, it's a warning of what can occur when political and religious leaders divide the world. It reminds us what really happens when civilizations clash.
