[6] According to the Mau stone inscription, Dhanga's chief minister Prabhasa retained the position during the reign of his successor Ganda.
R. K. Dikshit identified Dhanga with the king of Kalanjara who contributed contingents to the Hindu confederacy that was defeated by Mahmud of Ghazni at Peshawar in 1008 CE.
[9] In 1018 CE, Mahmud of Ghazni invaded Kannauj, whose king (possibly Rajyapala) fled the city, allowing the Ghaznvid army to sack it without facing much resistance.
Ali ibn al-Athir (12th century), a Muslim historian earlier than Firishta, named the king of Khajuraho as "Bida", a variant of "Vidya" (that is, Ganda's successor Vidyadhara).
Based on this, it can be inferred that Ganda's reign ended sometime before 1018 CE, when his successor defeated the ruler of Kannauj.
