Imperial expansion and consolidation
According to Tibetan sources, the emperors; Khri-srong-lda-btsan (Trisong Detsen) and his son, Mu-teg-btsan-po (Ralpacan), conquered India and made Dharmapala submit. Whether this is historically accurate has been debated between historians however it can be asserted that Devapala came into conflict with the Tibetans. Chinese records, indicate Tibetan control over the Himalayas was lost from 839 to 848 CE which was during Devapala's reign. During the period when Dharmapala's reign was coming to a close and Devapala's reign was beginning, the Pratihāra ruler Nagabhatta attacked the Palas allied with the Tibetan Empire. Devapala defeated the Tibetan kings. The Dullu inscription of King Prithvimalla confirms Devapala's conquest with the mention of the establishment of the Pala Dynasty of Nepal with the first ruler being Adipala whose lineage would continue to rule for sixteen generations.
