The First known date Dadd is 627 AD. From which this inference can be made, that this war must have occurred 629-30 AD. Dadd reigned until 640 CE, On the basis of which we can infer, that this war must have occurred between 630 and 640 AD.

Dadd was a simple ruler, who could not fight on a powerful ruler like Harsh alone, therefore, he must have fought this war with the help of Chalukya king Pulakeshin II. Pulakeshin’s Ehole inscription suggests that Dad was his feudal lord.
The incident which contributed to Harsh’s war with Dadd and Pulakeshan II’s contribution to help Dadd in this war became the cause of conflict between Harsh and Pulakeshin II.
Harsh married his daughter to Balbhi to bring the king to his side. Now the king of balbhi became a relative of Harsh.
