The Fourth Crusade (1202–1204) was 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 defeating the powerful Egyptian Ayyubid Sultanate. However, a sequence of economic and political events culminated in the Crusader army's 1202 siege of Zara and the 1204 sack of Constantinople, rather than the conquest of Egypt as originally planned. This led to the Partitio terrarum imperii Romaniae or the partition of the Byzantine Empire by the Crusaders and their Venetian allies leading to a period known as Frankokratia, or "Rule of the Franks" in Greek.
Enrico Dandolo was the doge of Venice from 1192 until his death. He is remembered for his avowed piety, longevity, and shrewdness, and is known for his role in the Fourth Crusade and the Sack of Constantinople. Dandolo died in 1205 in Constantinople and was buried at the Hagia Sophia.

He was elected by the Council of Forty in 1178 following the retirement of Sebastiano Ziani. Prior to this he had been an ambassador to Sicily in 1175, tasked with drawing up a treaty with King William II. He had also been the electors' first choice for doge following the death of Vitale II Michiel in 1172, but stepped aside in favour of Ziani, an older and wealthier man.

Louis I of Blois was Count of Blois from 1191 to 1205. He is best known for his participation in the Fourth Crusade and later prominent role in the Battle of Adrianople.
The siege of Zara or siege of Zadar was the first major action of the Fourth Crusade and the first attack against a Catholic city by Catholic crusaders. The crusaders had an agreement with Venice for transport across the sea, but the price far exceeded what they were able to pay. Venice set the condition that the crusaders help them capture Zadar, a constant battleground between Venice on one side and Croatia and Hungary on the other, whose king, Emeric, pledged himself to join the Crusade. Although some of the crusaders refused to take part in the siege, the attack on Zadar began in November 1202 despite letters from Pope Innocent III forbidding such an action and threatening excommunication. Zadar fell on 24 November and the Venetians and the crusaders sacked the city. After wintering in Zadar, the Fourth Crusade continued its campaign, which led to the siege of Constantinople.

The Byzantine Empire was ruled by emperors of the Angelos dynasty between 1185 and 1204 AD. The Angeloi rose to the throne following the deposition of Andronikos I Komnenos, the last male-line Komnenos to rise to the throne. The Angeloi were female-line descendants of the previous dynasty. While in power, the Angeloi were unable to stop the invasions of the Turks by the Sultanate of Rum, the uprising and resurrection of the Bulgarian Empire, and the loss of the Dalmatian coast and much of the Balkan areas won by Manuel I Komnenos to the Kingdom of Hungary.
The sack of Constantinople occurred in April 1204 and marked the culmination of the Fourth Crusade. Crusader armies captured, looted, and destroyed parts of Constantinople, then the capital of the Byzantine Empire. After the capture of the city, the Latin Empire was established and Baldwin of Flanders was crowned Emperor Baldwin I of Constantinople in the Hagia Sophia.
The Massacre of the Latins was a large-scale massacre of the Roman Catholic inhabitants of Constantinople, the capital of the Eastern Roman Empire, by the Eastern Orthodox population of the city in April 1182.
The Partitio terrarum imperii Romaniae, or Partitio regni Graeci, was a treaty signed among the crusaders after the sack of the Byzantine capital, Constantinople, by the Fourth Crusade in 1204. It established the Latin Empire and arranged the nominal partition of the Byzantine territory among the participants of the Crusade, with the Republic of Venice being the greatest titular beneficiary. However, because the crusaders did not in fact control most of the Empire, local Byzantine Greek nobles established a number of Byzantine successor kingdoms. As a result, much of the crusaders' declared division of the Empire amongst themselves could never be implemented. The Latin Empire established by the treaty would last until 1261, when the Empire of Nicaea reconquered Constantinople, re-establishing the Byzantine Empire. The various crusader principalities in southern Greece and the Aegean archipelago would last much longer, until they were conquered by the Ottomans in the 14th and 15th centuries.
The Diocese of Castello, originally the Diocese of Olivolo, is a former Roman Catholic diocese that was based on the city of Venice in Italy. It was established in 774, covering the islands that are now occupied by Venice. Throughout its existence there was tension between the diocese, the Patriarchate of Grado to which it was nominally subordinate, and the Doge of Venice. Eventually in 1451 the diocese and the patriarchate were merged to form the Archdiocese of Venice.
