Actually the period of Vatsar ja was the same as that of the peak of R rak a dynasty. The powerful King Dantidurga (730-753AD) of R rak a dynasty during 730-735AD merged the entire C lukya empire with his and created the most powerful M nyakhe a kingdom by defeating the C lukya R ja K rtivarm of B d m . After Dantidurga, 7th ruler K a-I of R rak a dynasty and his two sons Govinda-II and Dhruva i.e. gth and 9th rulers of R rak a dynasty also gradually increased the territorial empire of R rak a dynasty.
This increase in the power of R rak a dynasty created bad effect on Vatsar ja. Around 787AD, R rak a dynasty ruler Dhruva launched a powerful attack on Vatsar ja. Vatsar ja was defeated in that war. Besides giving up the rule of M law , Vatsar ja was forced to leave M law also for shelter towards Mar Prade a. Seeing the outreach and power of Dhruva's army, Vatsar ja became confident that neither taking back the rule over M law but his very existence in M law can be a cause of his destruction. Hence Vatsar ja went to capital of J b lipura (J lora) in Gujarat with his remaining forces and started ruling J lora.
A copper plate of aka 724 from the home nabhoga Narahariyappa in village Manne in Karnataka also states the defeat of Vatsar ja from Dhruva, leaving M law and going towards Mar dhara Prade a for shelter.
Vatsar ja, after his defeat spent his remaining life in J lora only. Vatsar ja had very friendly relations with Jain congregation.
