Ehsan Khan Kengerli (Azerbaijani: إحسان خان کنگرلی), later known by his Russified name of Ehsan Khan Nakhichevansky (Russian: Эхсан Хан Нахичеванский, Azerbaijani: إحسان خان ناخچیوانسکی; 1789–1846) was the last ruler of the Nakhichevan Khanate.
During the Russo-Persian War of 1826–1828, Abbas Mirza appointed Ehsan Khan as commander of the fortress Abbasabad.
[2] The khanate was formally abolished in 1828, but Ehsan Khan retained his influence in the region and was appointed the campaign ataman of Transcaucasian Muslim troops.
In 1831 he was decorated with 2nd class Order of Saint Anna, and in 1837 he was conferred the rank of major-general in the Russian army.
After the dissolution of the khanate, the khans of Nakhichevan took the Russified surname Nakhchivanski, and the men of its family traditionally joined the Russian military service.
