The Byzantine Empire made a large number of trade concessions to the Republic of Venice in exchange for military support against the Normans who were invading and conquering various Byzantine holdings in and outside the Empire. According to the treaty, the Byzantines would allow the Venetians the right to trade throughout the empire without the imposition of taxes. The Venetians would also be allowed control of the main harbor facilities of Byzantium (Constantinople), along with control of several key public offices. The treaty also granted various honors to the Doge of Venice, along with an income. Finally, the Venetians were granted their own district within Byzantium, with shops, a church, and a bakery, which could be compared to the concessions of 19th century colonialism.
