The decline of Venice was due to several economic, political and military challenges. Economically, the discovery of new trade routes to Asia bypassed Venice's role as a middleman, reducing its lucrative trade monopoly. Militarily, the constant wars with the Ottoman Empire drained Venice's resources and disrupted its naval trade. Politically, an outdated government system led to incompetent leadership decisions that hurt Venetian defenses and alliances. Over-reliance on expensive mercenary forces also undermined Venice's security and finances over time. These various challenges eroded Venice's power on the seas and in international affairs.
