Fourth Crusade (jan 16, 1202 – mar 29, 1204)
Description:
a Latin Christian armed expedition called by Pope Innocent III. The stated intent of the expedition was to recapture the Muslim-controlled city of Jerusalem, by first conquering the powerful Egyptian Ayyubid Sultanate, the strongest Muslim nation of the time. However, a sequence of economic and political events culminated in the Crusader army sacking the city of Constantinople, the capital of the Greek Christian-controlled Byzantine Empire.
In late 1202, financial issues led to the Crusader army sacking Zara, which was then brought under Venetian control. In January 1203, en-route to Jerusalem, the Crusader leadership entered into an agreement with the Byzantine prince Alexios Angelos to divert the Crusade to Constantinople and restore his deposed father as Emperor. The intent of the Crusaders was then to continue to Jerusalem with promised Byzantine financial and military aid. On 23 June 1203, the bulk of the Crusaders reached Constantinople, while smaller contingents continued to Acre. After the siege of Zara the pope excommunicated the crusader army.
In August, following clashes outside Constantinople, Alexios was crowned co-Emperor. However, in January 1204, he was deposed by a popular uprising. The Crusaders were no longer able to receive their promised payments from Alexios. Following the murder of Alexios on 8 February, the Crusaders decided on the outright conquest of the city. In April 1204, they captured and plundered the city's enormous wealth. Only a handful of the Crusaders continued to the Holy Land thereafter.
The conquest of Constantinople was followed by the fragmentation of the Empire into three rump states centred in Nicaea, Trebizond and Epirus. The Crusaders then founded several Crusader states in former Byzantine territory, largely hinged upon the Latin Empire of Constantinople. The presence of the Latin Crusader states almost immediately led to war with the Byzantine successor states and the Bulgarian Empire. The Nicaean Empire eventually recovered Constantinople and restored the Byzantine Empire in 1261.
The Crusade is considered to be one of the most prominent acts that solidified the schism between the Greek and Latin Christian churches, and dealt an irrevocable blow to the already weakened Byzantine Empire, paving the way for Muslim conquests in Anatolia and Balkan Europe in the coming centuries.
