Venetian Adriatic Trade

Timeline

1. 1131–1140Adriatic Sea · Adriatic SeaVenice built a trade monopoly network by controlling Adriatic coastal ports (such as Zara, Traù, and Kotor), escorting with armed merchant fleets, and collecting port dues and pilotage fees to keep routes secure. In the 1130s Venice maintained complex diplomatic relations with Hungary, Byzantium, and Dalmatian cities, ensuring unimpeded passage for northern German and Flemish goods transshipped through Venice to the East.
2. 1131–1140Constantinople · ConstantinopleVenetian merchants held chartered trading quarters in Constantinople, importing silk, spices, gems, and Byzantine crafts, then distributing them via the Adriatic to the Italian hinterland and Central Europe. Though the Byzantine Empire was in decline in the 1130s, it remained the core hub of Venetian eastern trade; commercial ties were close though political friction occasionally arose.
3. 1135–1140Eastern Mediterranean · LevantDuring the Venetian Crusade of 1122–1124, Doge Domenico Michiel led a large fleet east to aid the Holy Land and assisted the Kingdom of Jerusalem in capturing Tyre in July 1124. In return, Venice received one-third of Tyre's territory and commercial privileges elsewhere, markedly strengthening its commercial presence in the eastern Mediterranean thereafter.
