border finally saw their chance.
The Christian revival in Spain was a long, squabbling business, and the endless churn of its miniature kingdoms is a mind-numbing affair. By long-standing tribal tradition, its rulers left their territories to be divided among their children, and their children duly launched themselves into orgies of fratricide. As the ripples of war eddied back and forth, the rival monarchs made alliances of convenience with Muslim raiders as often as with their religious brethren. Yet gradually they moved south into the weakened city-states, and suddenly a spectacular upset of history was within their grasp.
Around the turn of the millennium, western Europe had finally begun to throw off its bloodstained blanket of darkness. The Vikings had started to settle down and convert to Christianity. France had begun to emerge from the western parts of Charlemagne’s old empire, while the Holy Roman Empire, the forerunner of Germany, soldiered on in its eastern lands. The Roman Church had recovered from an ignominious low point, and once again it had begun to dream of increasing its flock. It saw its chance in Spain.
In 1064 the papacy gave its backing to war against the Muslims of al-Andalus—the first Christian war overtly fought against an enemy that was defined by its faith. From then on the Spanish marched—protected, if never exactly united—under the papal banner. They went into battle armed with an ironclad guarantee from Christ’s representative on earth: mass indulgences for those who died, which absolved them of doing penance for their sins and guaranteed immediate admittance to heaven.
The struggle soon developed a name—the Reconquest—that swept aside the inconvenient fact that most of the peninsula had been Muslim territory for longer than it had been Christian. Ahaphazard flurry of battles fought for personal glory and territorial expansion was transformed into a war of religious liberation, and it boasted its own patron saint in the form of the Apostle James. St. James— Santiag o in Spanish—had been beheaded in Jerusalem a few years after Jesus’s death, but a hermit guided by a star had miraculously unearthed his bones in a Spanish field. In his unlikely new afterlife, Jesus’s companion was transformed into Santiago Matamoros —“St. James the Moor-slayer”—with Moro , from the Roman name for the Berbers, being the catchall term that Iberia’s Christians applied to Muslims, Berber and Arab alike. The Moor-slayer lent his name to the Order of Santiago, one of many military brotherhoods that sprang up to wage war on Islam, and the order adopted a stirring motto: “May the sword be red with Arab blood.” From then on the Apostle regularly showed up in the heat of battle, dressed in shining armor and riding a white horse, urging on his followers to stick it to the Infidel.
Even now, not all of Spain’s Christians were so sure where their loyalties lay. This was the time of El Cid, who earned a glowing reputation as a Spanish hero despite being a soldier for hire by Muslims and Christians alike. In 1085 El Cid’s sometimes master, the wily and ambitious Alfonso the Brave of Castile and Leon, inveigled his way into control of the old fortress city of Toledo, and Christian Toledo took over from ruined Córdoba as Europe’s capital of culture. Inside a synagogue designed by Muslim architects, its Christians, Muslims, and Jews celebrated their rites alongside each other. In its School of Translators, Muslims and Jews collaborated to translate medical, scientific, and philosophical texts from Arabic to Latin. Travelers crisscrossed the Pyrenees, introduced Islamic culture and learning to the rest of Europe, and transformed its intellectual life along with its decorative styles, recipes, fashions, and songs. In the twilight of convivencia, the Spanish had become the masters of modernity.
Toledo was one last bright flare of what could have been, one final, chaotic explosion of
