To examine how Venetian seapower grew to become an effective force in the Mediterranean, an examination of how Venice herself came to exist must be conducted. After understanding how and why the Venetian Arsenal was the leading European shipbuilding center in the Mediterranean by the sixteenth century, as well as how and why Venetian shipwrights and artillerists by the fifteenth century were world leaders in artillery- and naval-innovation, conceptualizing the outcomes of the conflicts that Venice played a role in such as the battle of Lepanto will be possible. By covering key medieval Venetian terms of vocabulary, a better picture of Venetian seapower can be envisaged. A picture of medieval Venetian seapower must be clear in order to determine how it has influenced the Mediterranean in the early modern period. To conclude, a theory attempting to scry what the Mediterranean may have looked like by the twentieth century if the Venetian Arsenal never existed will be presented.
