The date of the conflict between the two kings is not certain. The Annals of the Tang dynasty suggest that Lalitaditya and a Central Indian king had fought against Tibet as allies. Assuming that this central Indian king was Yashovarman (after his subjugation by Lalitaditya), M. A. Stein dated Lalitaditya's conquest to sometime before 736 CE. However, Mishra interprets the Tang records differently to theorize that Lalitaditya and Yashovarman were allies at least until 736 CE. According to Mishra, the conflict between Lalitaditya and Yashovarman took place after 736 CE, and before Yashovarman's death in 749-753 CE.
