Fourth Crusade — Sack of Constantinople
The Fourth Crusade set out in 1202 with the stated aim of attacking Egypt — correctly identified as the strategic heart of Muslim power — but it never came close to that objective. The crusaders had contracted with Venice to transport them to Egypt, but they could not pay the agreed fee. Venice, under the aged and formidable Doge Enrico Dandolo, offered an alternative: assist Venice in recovering the port of Zara (a Christian city under Hungarian rule) in lieu of payment. Pope Innocent III excommunicated the crusaders for attacking Zara, then lifted the excommunication — a moral confusion that set the tone for what followed. A Byzantine dynastic dispute then provided a further diversion. The exiled prince Alexios, son of the deposed Emperor Isaac II, promised the crusaders enormous rewards — 200,000 silver marks, Byzantine military support, and union of the Eastern and Western churches — if they would restore his father to the throne. The temptation was irresistible. In July 1203, the crusader fleet sailed through the Bosphorus and installed Isaac and Alexios as co-emperors. But Alexios could not deliver on his promises; he lacked the money and his people resented the Latins. A palace coup killed him in early 1204. What followed was three days of catastrophic violence. On 12 April 1204, the Crusader and Venetian forces breached Constantinople's walls — walls that had never been taken by external assault in nearly nine centuries. For three days the city was systematically looted. The treasury of Hagia Sophia was stripped. Ancient statues, manuscripts, and relics accumulated over a thousand years were destroyed or carried west. The bronze horses of the Hippodrome were shipped to Venice, where they remain above the door of St. Mark's Basilica. A prostitute sat on the Patriarch's throne in Hagia Sophia and sang bawdy songs. Pope Innocent III, initially horrified, ultimately acquiesced as a Latin Empire was established under Count Baldwin of Flanders. Venice acquired a strategic network of ports and islands. The Byzantine Empire fragmented into successor states. The sack ended Byzantine power as a Mediterranean force and ensured that when the Ottomans threatened Constantinople in 1453, there was no Western rescue. For the Orthodox world, April 1204 remains a defining trauma — the moment when Western Christianity proved itself not merely schismatic but predatory.
