Prince Alexander of Kartli (died 1773)

Alexander (Georgian: ალექსანდრე), also known as Ishaq Beg (ისაკ-ბეგი) (c. 1705/8 – September 1773), was an illegitimate son of the Georgian ruler Jesse of Kartli, of the Bagrationi-Mukhraneli, politically active in Georgia in the 1740s. His progeny subsequently flourished in the Russian Empire, producing several notable figures of the 19th century, among them General Pyotr Bagration of the Napoleonic Wars fame.
