Ilia (Georgian: ილია; Russian: Илья Георгиевич, Iliya Georgiyevich), also known as Elizbar (ელიზბარი), (2 September 1790 – 18 July 1854) was a Georgian prince royal (batonishvili), a son of George XII, the last king of Kartli and Kakheti, by his second marriage to Mariam Tsitsishvili. After the Russian annexation of Georgia in 1801, Ilia accompanied his mother into exile to Russia. He then received military training and served in the Russian army, fighting with distinction at the battle of Borodino against the French in 1812 and retiring with the rank of colonel in 1823. He had 13 children of his marriage with Princess Anastasia Obolenskaya and his descendants, bearing the surname of Gruzinsky, have survived in the 21st-century Russian Federation.
