4.1.2

According to the narrative of Ahmud-oolla Moostowfy, Aluptugeen retained his independence fifteen years, during which period his general, Subooktugeen, being engaged in frequent wars with the Indians, as often defeated them. Aluptugeen died in the year 365, and his son Aboo-Isaac, accompanied by Subooktugeen, proceeded to Bokhara. At this time Aboo-Isaac received a formal commission from Munsoor, as governor of Ghizny; and Subooktugeen was also appointed by the king his deputy and provisional successor. Aboo-Isaac survived this event but a short period, when Subooktugeen, in the year 367, was unanimously acknowledged king by the chiefs of Ghizny. On this occasion, also, he espoused the daughter of Aluptugeen, and became as celebrated for his justice in the administration of his affairs as for the great popularity he acquired among his subjects, of all conditions.
