Fourth Crusade - Outcome

Outcome

Almost none of the crusaders ever made it to the Holy Land, and the unstable Latin Empire siphoned off much of Europe's crusading energy. The legacy of the Fourth Crusade was the deep sense of betrayal the Latins had instilled in their Greek coreligionists. With the events of 1204, the schism between the Church in the West and East was not just complete but also solidified. As an epilogue to the event, Pope Innocent III, the man who had unintentionally launched the ill-fated expedition, thundered against the crusaders thus:

How, indeed, will the church of the Greeks, no matter how severely she is beset with afflictions and persecutions, return into ecclesiastical union and to a devotion for the Apostolic See, when she has seen in the Latins only an example of perdition and the works of darkness, so that she now, and with reason, detests the Latins more than dogs? As for those who were supposed to be seeking the ends of Jesus Christ, not their own ends, who made their swords, which they were supposed to use against the pagans, drip with Christian blood, they have spared neither religion, nor age, nor sex. They have committed incest, adultery, and fornication before the eyes of men. They have exposed both matrons and virgins, even those dedicated to God, to the sordid lusts of boys. Not satisfied with breaking open the imperial treasury and plundering the goods of princes and lesser men, they also laid their hands on the treasures of the churches and, what is more serious, on their very possessions. They have even ripped silver plates from the altars and have hacked them to pieces among themselves. They violated the holy places and have carried off crosses and relics.

Nevertheless, the Pope's negative reaction was short-lived. When the crusaders took the piles of money, jewels, and gold that they had captured in the sack of Constantinople back to Rome, Innocent III welcomed the stolen items and agreed to let the crusaders back into the Church. Furthermore at the Fourth Council of the Lateran the Pope welcomed and recognised to it western (Catholic) prelates from Sees established in the conquered lands—thus recognising their legitimacy over formerly Orthodox areas.

The Latin Empire was soon faced with a great number of enemies, which the crusaders had not taken into account. Besides the individual Byzantine Greek states in Epirus and Nicaea, the Empire received great pressure from the Seljuk Sultanate and the Bulgarian Empire. The Greek states were fighting for supremacy against both Latins and each other. Almost every Greek and Latin protagonist of the event was killed shortly after. Murtzuphlus' betrayal by Alexius III led to his capture by the Latins and his execution at Constantinople in 1205. Not long after, Alexius III was himself captured by Boniface and sent to exile in Southern Italy; he died in Nicaea in 1211. On 14 April 1205, one year after the conquest of the city, Emperor Baldwin was decisively defeated and captured at the Battle of Adrianople by the Bulgarians; he was executed by the Bulgarian Emperor Kaloyan in 1205 or 1206. Two years after that, on 4 September 1207, Boniface himself was killed in an ambush by the Bulgarians, and his head was sent to Kaloyan. He was succeeded by his infant son Demetrius of Montferrat, who ruled until he reached adulthood, but was eventually defeated by Theodore I Ducas, the despot of Epirus and a relative of Murtzuphlus, and thus the Kingdom of Thessalonica was restored to Byzantine rule in 1224.

Various Latin-French lordships throughout Greece—in particular, the duchy of Athens and the principality of the Morea—provided cultural contacts with western Europe and promoted the study of Greek. There was also a French cultural work, notably the production of a collection of laws, the Assises de Romanie (Assizes of Greece). The Chronicle of Morea appeared in both French and Greek (and later Italian and Aragonese) versions. Impressive remains of crusader castles and Gothic churches can still be seen in Greece. Nevertheless, the Latin Empire always rested on shaky foundations. The city was re-captured by the Nicaean Greeks under Michael VIII Palaeologus in 1261, and commerce with Venice was re-established.

In an ironic series of events, during the middle of the 15th century, the Latin Church (Roman Catholic Church) tried to organise a new crusade which aimed at the restoration of the Eastern Roman or Byzantine Empire which was gradually being torn down by the advancing Ottoman Turks. The attempt, however, failed, as the vast majority of the Byzantine civilians and a growing part of their clergy refused to recognize and accept the short-lived near Union of the Churches of East and West signed at the Council of Florence and Ferrara by the Ecumenical patriarch Joseph II of Constantinople. The Greek population, inspired by aversion from the Latins and the Western states, held that the Byzantine civilization which revolved around the Orthodox faith would be more secure under Ottoman Islamic rule. Overall, religious-observant Byzantines preferred to sacrifice their political freedom and political independence in order to preserve their faith's traditions and rituals in separation from the Roman See. In the late 14th and early 15th century, two kinds of crusades were finally organised by the Kingdoms of Hungary, Poland, Wallachia and Serbia. Both of them were checked by the Ottoman Empire. During the Ottoman siege of Constantinople in 1453, a significant band of Venetian and Genoese knights died in the defence of the city.
