As part of their ambition to expand towards the south, Russia entered Ottoman territory at its weak point, the south Caucasus, and occupied Kars in 1828. In the same year Russia signed the Turkmencay agreement with Iran and Russian rule began in the region. The following year, with British intervention, another agreement was signed in Edirne and Russia was given the city of Ahiska and six Ottoman sub-provinces as compensation in return for their withdrawal from Kars.
During the Crimean War (1853-1856), Russia’s Caucasian army attacked Kars again. Marshal Vasif Pasha defended the city with 16 battalions and for the first time the people of Kars joined in the battle to defend their land, but when no additional military support came from Erzurum and the Black Sea, the city fell.
Canadian General Williams, who during this war was attached to the Ottoman army as a British military observer, later wrote in his memoirs that he witnessed how people defended their country during the resistance in Kars. Still, the Ottoman army accepted defeat and retreated from Kars. Russia entered the city once again, but withdrew again after the Paris meetings of 1865.
