Kakustha (Gurjara-Pratihara dynasty)
Kakustha (8th century CE) was a rajput king from the Pratihara dynasty. According to the Gwalior inscription of Mihira Bhoja, Kakustha was the elder son of an unnamed brother of Nagabhata I. Devaraja was the younger brother and successor of Kakustha. It is found that Kakustha and his successor Devaraja ruled between c. 760 CE and 780 CE.[1]
The Gwalior inscription states that Kakustha added to the family's fame. It further mentions that he was known as Kakkuka. The word means "one who always laughs".
