Treaty of London demands an Ottoman armistice in Greece

Background. The Greek War of Independence (1821–1829) saw Greek revolutionaries fighting against the Ottoman Empire. By 1826, the conflict had reached a critical phase, with the Ottoman Navy resupplying garrisons and threatening to crush the rebellion. The Great Powers—Russia, Britain, and France—decided to intervene, sending naval squadrons to Greece in 1827 to support the insurgents.

Diplomatic Context. Prior to the Treaty of London, diplomatic efforts included the Akkerman Convention of 1826, where the Sultan accepted Russian demands regarding Serbia and the principalities. British Foreign Secretary Canning prepared for action by negotiating the Treaty of London with France and Russia, aiming to secure an armistice and establish a framework for intervention in the Greek conflict.

Treaty Provisions. Signed in London on 6 July 1827, the treaty involved the United Kingdom, Bourbon Restoration France, and the Russian Empire. It demanded that the Ottoman Empire accept an armistice in Greece. The agreement anticipated potential conflict, as evidenced by the outbreak of war between Russia and Turkey in June 1828, following the treaty's stipulations.
