The Kingdom of Kakheti was a late medieval and early modern monarchy in eastern Georgia, centered at the province of Kakheti, with its capital first at Gremi and then at Telavi. It emerged in the process of a tripartite division of the Kingdom of Georgia in 1465 and existed, with several brief intermissions, until 1762 when Kakheti and the neighboring Georgian kingdom of Kartli were merged through a dynastic succession under the Kakhetian branch of the Bagrationi dynasty. Through much of this period, the kingdom was a vassal of the successive dynasties of Iran, and to a much shorter period Ottoman Empire, but enjoyed intermittent periods of greater independence, especially after 1747.
