In 1082, the Byzantine emperor Alexios I granted Venice extensive commercial privileges in return for naval support against the Normans. The treaty gave Venetian merchants major advantages in Byzantine ports. It became a turning point in the commercial history of the eastern Mediterranean.

The treaty helped create the merchant networks through which stories, manuscripts, luxury goods, and languages moved between East and West. Later Mediterranean travel writing, romance, and urban poetry grew in a world increasingly shaped by Venetian commercial reach.
