Historical Trajectory
Phase I: Rise
Venice seized the Peloponnese peninsula from the Ottoman Empire during the Morean War of 1684–1699, part of the broader Holy League campaign following the failed Ottoman siege of Vienna. Venetian forces under Francesco Morosini systematically captured the region, and Venice formally organized it as the Kingdom of the Morea, appointing governors and establishing administrative structures to integrate this strategically significant territory.
Phase II: Zenith
At its height, Venetian administration controlled the entire Peloponnese and undertook efforts to repopulate the war-depopulated region by encouraging settlement from neighboring areas. Agricultural revitalization and economic reorganization were pursued, and Venice invested in fortifications and infrastructure. The kingdom represented the furthest eastward extension of Venetian territorial power in this period.
Phase III: Decline
Despite administrative efforts, Venice failed to secure the loyalty of the local Greek population or build adequate military defenses. When the Ottoman Empire launched a reconquest campaign in the summer of 1715, Venetian resistance collapsed within months. The entire Peloponnese was retaken by September 1715, ending Venetian rule permanently and restoring Ottoman control over the region.
