Jerusalem: The Biography

Abu al-Abbas declared himself caliph and invited the Umayyads to a banquet to declare his peaceful intentions. In the midst of the feast, the waiters drew out clubs and swords and butchered the entire family, tossing the bodies into the lamb stew. The Slaughterer himself died soon afterwards but his brother Mansur, the Victorious, systematically murdered the Alid family and then liquidated the overmighty Abu Muslim too. His perfumier, Jamra, later told how Mansur kept the keys of a secret storeroom which was to be opened only on his death. There his son later found a vaulted chamber filled with the bodies, each meticulously labelled, of the family of Ali from old men to infants, whom Mansur had killed, all preserved in the hot dry air.

Wiry with brown, weather-beaten skin and saffron-dyed hair, Mansur was the real father of the Abbasid dynasty that ruled for many centuries, but his power-base was to the east: he moved his capital to his new Round City, Baghdad.

Soon after seizing power, Mansur visited Jerusalem. There he repaired the damaged Aqsa, but paid for this work by melting the gold and silver doors of the Dome of the Rock given by Abd al-Malik. Mansur’s successors no longer bothered to visit. Just as the city diminished in the Islamic world, ^* a western emperor revived the Christian fascination with Jerusalem.⁷

THE EMPEROR AND THE CALIPH: CHARLEMAGNE AND HAROUN AL-RASHID

On Christmas Day 800, Charles the Great, known as Charlemagne, the King of the Franks, who ruled most of modern France, Germany and Italy, was crowned emperor of the Romans by the pope in Rome. This ceremony marked the new confidence of the popes and their western Latin-based Christianity that would become Catholicism – and their growing differences with the Greek-speaking Orthodox of Constantinople. Charlemagne was a merciless warrior-king hacking his way to ever-greater power, yet he was also fascinated with history, and as devout as he was ambitious: he saw himself as the heir to the missions of Constantine and Justinian to become the universal holy Roman emperor, and as a latter-day King David – and both these aspirations led to the Holy City. So earlier on the same Christmas Day, it was said that a delegation sent by the Patriarch of Jerusalem had presented him with the keys of the Holy Sepulchre. Rome and Jerusalem in one day was no mean feat.

This was not a bid for possession because the patriarch had the blessing of Jerusalem’s ruler, Caliph Haroun al-Rashid whose reign, recounted in the Thousand and One Nights

, was the apogee of the Abbasid empire. Charlemagne and the caliph had been exchanging envoys for three years: Haroun was probably keen to play off the Franks against his enemies in Constantinople and Jerusalem’s Christians needed Charlemagne’s help.

The caliph sent Charlemagne an elephant and an astrolabe water clock, a sophisticated device that showed off Islamic superiority – and alarmed some of the primitive Christians as a contraption of diabolical sorcery. The two emperors did not sign a formal treaty, but Christian property in Jerusalem was listed and protected, while Charlemagne paid the entire poll tax for the city’s Christians – 850 dinars. In return Haroun allowed him to create a Christian quarter around the Holy Sepulchre, with a convent, library and pilgrims’ hostel, staffed by 150 monks and seventeen nuns. ‘The Christians and pagans’, noted one pilgrim, ‘have this kind of peace between them.’ This generosity generated the story that Charlemagne had covertly visited Jerusalem, making him the heir of Heraclius, and playing into the mystical legend of the Last Emperor whose reign would herald the End Days. This was widely believed, particularly in the age of the Crusades, but Charlemagne never did visit Jerusalem.⁸

When Haroun died, the civil war between his sons was won by Maamun. The new caliph was an enthusiastic student of science, founding the famous literary-scientific academy, the House of Wisdom, commissioning a world map and ordering his sages to calculate the circumference of the globe.^* In 831, arriving in Syria to organize a campaign against Constantinople, Maamun probably visited Jerusalem, where he built new gates on the Temple Mount, but he erased Abd al-Malik’s name in the Dome to emphasize the superiority of the Abbasids and had it replaced with his own. He did not just take his name, he also purloined his gold from the Dome which remained a grey lead colour for over a thousand years. It got its gold back in the 1960s – but Abd al-Malik never got his name back and Maamun’s remains there to this day.⁹
