Which major Venetian territories were lost to the Ottoman Empire?

Over several centuries, the Republic of Venice lost significant portions of its overseas empire to the expanding Ottoman Empire. Key territories lost include:

• Albania and Greece: Important ports of call were lost in 1503.1
• Aegean Islands: Islands north of Crete were ceded in 1540.1
• Cyprus: This major territory was lost to the Ottomans in 1571.21
• Crete: Following a protracted conflict (1645–1669), Venice lost its last major possession in the eastern Mediterranean, retaining only a few strongholds.21
• The Morea (Peloponnese): After being liberated by Venetian forces in the late 17th century, this territory was returned to the Ottomans in 1718 under the terms of the Treaty of Passarowitz.23

These losses, coupled with the discovery of new trade routes to the East and West, contributed to Venice's transition from a dominant Mediterranean power to a state of economic and political decline.21
