The Russo-Turkish War of 1828–1829 resulted from the Greek War of Independence of 1821–1829; war broke out after the Ottoman Sultan Mahmud II closed the Dardanelles to Russian ships and in November 1827 revoked the 1826 Akkerman Conventionin retaliation for the participation of the Imperial Russian Navy in the Battle of Navarino of October 1827.
The Ottoman Empire had bloodily abolished its centuries-old regular army, the Janissary Corps, in 1826. A year later, Great Britain, France, and Russia jointly raided the Ottoman Navy at Navarino. When war broke out between the Ottomans and Russia in 1828, the Ottomans possessed neither a regular army nor a navy. After suffering several defeats, both in the Balkans and in the Caucasus, the Sultan decided to sue for peace, which resulted in the signing of the Treaty of Adrianople on 14 September 1829.
