Constantinople Under Siege

We saw yesterday that hostility between Byzantines and the Fourth Crusade came to a head when the new(est) emperor, Alexios V, ejected all the foreigners from the city and began reinforcing the defenses. The Crusaders of course had brought siege engines with them for use against Saracens in the Holy Land, but they were happy to use them here against a Christian city.

The first assault came on 9 April 1204 on the northwest walls. Unfortunately (for the westerners), the open ground between the shore and the wall left them open to a hail of arrows. That and bad weather made them retreat.

The weather cleared a few days later, so on 12 April the Crusaders attacked again. They managed to knock a few holes in the wall sufficient for knights to crawl through. Meanwhile, Venetians were scaling the walls and encountering the ferocious Varangian Guards. The northwest was the site of the Palace of Blachernae, where the emperors prior to Alexios V had barricaded themselves. The Crusaders used Blachernae as a base. Creating a wall of fire to defend their base got out of hand and started burning down other parts of the city.

Emperor Alexios V fled the city that night. The Crusaders spent three days looting and pillaging. Now we come to the point of the week-long build-up to explain the last paragraph of this post about influences of Italo-Byzantine art. Constantinople was looted of many of its art treasures, which found there way west to reside in and influence Western Europe.

St. Mark's Basilica in Venice became the recipient of a large number of valuable artworks, thanks to Doge Enrico Dandolo commanding them as part of the Crusade's debt to Venice. Bronze horses from the Hippodrome, a sculpture of Four Tetrarchs (confirmed by the broken-off foot being identified in Constantinople), marble reliefs (including of Alexander the Great), and even carved marble pillars taken from Byzantine buildings—these and more found their way to Venice. The Treasury of San Marco (see more here) is full of the spoils of Constantinople.

Icons and other artworks were claimed by Crusaders and became family heirlooms.

Other art was too large to take but had more valuable purposes. Gold, silver, bronze artifacts were melted down for their value in precious metal and to become coins. Contemporary historian Niketas Choniates mentions a bronze statue of a resting Hercules that was so large "it took a cord the size of a man's belt to go round the thumb, and the shin was the size of a man." That and hundreds of bronze statues at the Hippodrome were melted down. So also was a bronze statue of Hera, so large that her head alone needed four oxen to move it. You can see a longer list by Niketas Choniates here.

So what happened afterward to Constantinople? I'm going to turn back to the Western European knight who also wrote a history, Geoffrey de Villehardouin, and talk tomorrow about how history is written by the victors.

Regime Change in Constantinople

We saw yesterday that very early in 1204 Isaac and Alexios were holed up in the Palace of Blachernae against the upset citizenry, who held an election to choose another leader (who did not want anything to do with it, and fled to Hagia Sophia for sanctuary). The two sent a trusted advisor, Alexios Doukas Mourtzouphlos, to seek help from the Crusaders, whom the citizenry were also attacking.

Doukas, who had until recently been imprisoned because he had tried to overthrow Isaac's brother (who had usurped the throne from Isaac in 1195 and blinded and imprisoned Isaac), took on the assignment, but considered a way to satisfy everyone involved—and by everyone, he included himself.

Doukas went to the main palace and approached the Varangian Guards—essentially Vikings who were personal bodyguards for Byzantine Emperors—with bribes. Niketas Choniates wrote that he had help from a eunuch who had access to the treasure, but this was unnecessary, since Doukas after his release from prison was made protovestiarios—"first of the wardrobe"—a position as head of imperial finances.

Doukas made himself Emperor Alexios V. On the night of 27 January, the Varangian Guards arrested Issac and Alexios. Alexios was strangled in prison about a week later, and Isaac, old and feeble already, died around the same time. The previously elected Nicholas Kanabo was brought from Hagia Sophia and offered a position in the new emperor's court, but refused. He fled again to the Hagia Sophia but was dragged from it and killed on its steps. (Having been elected by a majority, he was a "loose thread" that a new emperor could not allow to have a rebellion form around.)

Alexios V met with Doge Enrico Dandolo (the meeting was illustrated by Gustave Doré; see above) to negotiate a resolution to the conflict between the Empire and the Fourth Crusade, but there was no easy solution. The Empire did not have the money even to help itself, never mind pay enormous sums that had been promised by the younger Alexios. The Crusaders insisted that Alexios IV, with whom they had the agreement, be restored to the throne. This demand is probably why Alexios IV was killed, to eliminate any reason for the Crusaders to attempt a coup.

Alexios V confiscated money from the aristocracy (endearing himself to the lower classes but alienating his friends and relatives) in order to begin fortifying the city against the inevitable clash with the Crusading army. The death of Alexios IV was a further sign that Constantinople was not about to deal with the Crusaders in good faith. In March of 1204, all members of the Crusade who had taken up residence in the city were rounded up and expelled. That was the final straw.

The Crusaders drew up battle plans, and then made ready to put them into action. See you next time.

Crusade versus Constantinople

(It would be best to ready yesterday's post to understand where we are.)

So the Fourth Crusade was now in Constantinople, waiting to get support of men and money from Emperor Alexios IV Angelos per their agreement for putting him on the throne (even though they had to coerce his blind emperor father Isaac II to elevate the son).

Emperor Isaac must have been horrified when he discovered the offer made by his son to the Crusade. Isaac knew very well that Constantinople could not provide the 200,000 silver marks on top of 34,000 marks needed to repay a debt to Venice, or the thousands of soldiers promised to join the Crusade. Much of the financial problem was due to Isaac's brother Alexios III, who had usurped the throne in 1195 and fled to Thrace when the Crusaders attacked the city on 18 July 1203. Alexios III had cemented his power after usurpation with lavish bribes, depleting the treasury. When he fled, he took 1000 pounds of gold with him.

Alexios IV scraped together 100,000 silver marks by confiscating church treasures and property of those he considered enemies (supporters of his uncle), and sacking some Thracian towns. By December, however, it was clear that the Crusade was not going to get the support they were promised. Foolishly, Alexios did not even try to placate them further, stating "I will not do any more than I have done."

Meanwhile, the citizens of Constantinople were increasingly annoyed with the overbearing Westerners, and the young emperor who had brought them there and now was proving to be an incompetent ruler. The locals started acting violently toward the Europeans, attacking and killing many. Isaac compounded the problem by spreading rumors that his son kept company with "depraved men." A contemporary historian, Niketas Choniates (c.1155 - 1217) criticized Alexios' childishness, his lavish lifestyle, and his familiarity with the Western outsiders. Alexios, quite foolishly, tried to teach the Crusaders a lesson (and get the citizens on his side) by setting fire to several ships and aiming them at the Venetian fleet. (The illustration is the Venetian fleet at the shore, from a 15th century miniature.)

By January 1204, the citizens of Constantinople had had enough with the Crusaders and with the rulers that were ineffective at dealing with this threat to the city. They wanted a new emperor, and the senate and priests and populace gathered to find one. Anyone who had been paying attention knew the situation was hopeless: the Crusaders would not go away without Alexios' agreement being satisfied, and there was no way to meet their demands. On 27 January 1204 they elected Nicholas Kanabos, a young noble described by Choniates as "gentle by nature, of keen intelligence, and versed in generalship and war". He absolutely refused the authority they wanted to give him and fled to the Hagia Sophia for sanctuary.

Knowing that the citizenry en masse wanted them gone, Isaac and Alexios barricaded themselves in the Palace of Blachernae, one of the imperial residences in the northwestern part of the city. (On the Second Crusade, Louis VII and Eleanor of Aquitaine had been hosted there.) They sent a trusted advisor, Alexios Doukas Mourtzouphlos, to go to the Crusaders and get help. Doukas had tried to overthrow Isaac's usurping uncle and been imprisoned for it. When Isaac was restored, Doukas was released and put in charge of the federal finances. Isaac felt Doukas was a man he could trust.

That was a mistake. Tomorrow the Byzantine intrigue goes on, and includes Vikings!
