The most prosperous period of the Abkhazian kingdom was between 850 and 950, when it dominated the whole western Georgia and claimed control even of the easternmost Georgian provinces. The terms "Abkhazia" and "Abkhazians" were used in a broad sense during this period – and for some while later – and covered, for all practical purposes, all the population of the kingdom regardless of their ethnicity. In 989, the Bagratid ruler Bagrat III came to power in Abkhazia which he inherited from his mother Guranduxt Anch'abadze. In 1008 Bagrat inherited K'art'li from his father and united the kingdoms of Abkhazia and Georgia into a single Georgian feudal state.
