Montreux Convention

• According to the 1936 Montreux Convention Regarding the Regime of the Straits, often referred to simply as the Montreux Convention, Turkey has control over both the Bosporus and Dardanelles straits.
• In the event of a war, the pact gives Ankara the right to regulate the transit of naval warships and to block the straits to warships belonging to the countries involved in the conflict.
• Article 19 of the treaty contains an exception for the countries on the Black Sea that can effectively undermine Turkey’s power in blocking the warships entering or exiting the Black Sea.

Activation of Montreux Convention

• Situation in Ukraine had become a war, a declaration that authorises Ankara to activate the Montreux Convention and ban Russian war vessels from entering the Black Sea through the Bosporus and Dardanelles straits.
