The Treaty of Lausanne is the last negotiated settlement in the aftermath of World War One that remains intact today. Replacing the Treaty of Sevrés, the Lausanne Treaty ultimately would define the borders and modern nations in the Mediterranean and Middle East.

The Lausanne Treaty continues to be upheld today, though violations of the treaty have brought several nations close to conflict and full-blown war.

The Treaty of Sevrés

The Treaty of Lausanne initially didn’t define the modern borders of the Mediterranean, and the Treaty of Sevrés preceded it. When the Ottomans capitulated to the Entente from World War One, their empire was partitioned into various zones of influence.
