The Russo-Turkish War of 1828–1829 was sparked by the Greek War of Independence of 1821–1829. War broke out after the Ottoman Sultan Mahmud II closed the Dardanelles to Russian ships and revoked the 1826 Akkerman Convention in retaliation for Russian participation in the Battle of Navarino.

Nicholas I was Emperor of Russia, King of Congress Poland, and Grand Duke of Finland. He was the third son of Paul I and younger brother of his predecessor, Alexander I. Nicholas's reign began with the failed Decembrist revolt. He is mainly remembered in history as a reactionary whose controversial reign was marked by geographical expansion, centralisation of administrative policies, and repression of dissent. Nicholas had a happy marriage that produced a large family; all of their seven children survived childhood.
