According to a tradition first recorded in the work of the 11th-century Georgian chronicler Sumbat Davitis-Dze, and repeated much later by Prince Vakhushti Bagrationi (1696–1757) the dynasty claimed descent from the biblical king and prophet David and came from Israel around 530 AD. The tradition had it that of seven refugee brothers of the Davidic line, three of them settled in Armenia and the other four arrived in Kartli (also known as Iberia), where they intermarried with the local ruling houses and acquired some lands in hereditary possession, with one of the four brothers, Guaram (died in 532), founding a line subsequently called "Bagrationi" after his son Bagrat. A successor, Guaram, was installed as a presiding prince of Iberia under the Byzantine protectorate, receiving on this occasion the Byzantine court title of "Kouropalates" in 575. Thus, according to this version, began the dynasty of the Bagratids, who ruled until 1801.
