Taking advantage of the internal dissensions in the Pāla Kingdom, Vijayasena seems to have strengthened himself in Eastern and Western Bengal, and when the Conquest of Southern Varendra.weakness of the Pālas under Madanapāla became apparent, he invaded Northern Bengal and succeeded in wresting the southern part of Varendra. Madanapāladeva seems to have continued to hold the northern part of Varendra, as his Manahali Grant was issued in the 8th year of his reign from the royal city of Rāmāvatī.[1]
We learn from the Deopārā inscription that Vijayasena attacked the King of Gauḍa with great force:—
Tvaṁ Nānya-Vīra-vijay-īti giraḥ kavīnāṁ śrutvās-nyathā-manana-rūḍha-nigūḍha roṣaḥ। Gauḍendram-adravad-apākṛta Kāmarūpabhūpaṁ Kaliṅgam-api yas-tarasā jigāya. v. 20.[2]
Most probably Madanapāla is the Gauḍendra mentioned in the verse quoted above. It is stated in the Deopārā inscription that Vijayasena defeated and Conquest of Northern Varendra.imprisoned the King of Mithilā named Nānyadeva, so most probably Vijayasena conquered the remaining portion of Varendra before he turned his attention towards the neighbouring district of Mithilā. Madanapāla's dominions were confined to the limits of Magadha after this. Vijayasena invades Magadha.Vijayasena did not remain content with Varendra. He despatched a flotilla of armed boats for the conquest of the Western regions.

But the expedition does not seem to have been very successful, as otherwise the incident would surely have been mentioned in Sena inscriptions. Madanpāladeva was greatly assisted in his war against Vijayasena by Candradeva, the founder of the Gahaḍavālā Dynasty of Kanauj. The author of the Rāmacarita has gratefully acknowledged this in his work:—
Siṁhī-suta-vikrānten-arjjuna-dhāmnā bhuvaḥ pradīpena। Kamalā-vikāśa-veṣaja vīṣajā Candreṇa vandhunopetām॥ 20. Caṇḍī-caraṇa-saroja-prasāda-sampanna-vigraha-Śrīkaṁ। Na khalu Madanaṁ s-āṅgeśam-īśáṁ agād jagad-vijayalakṣmīḥ. v. 21.[4]
Madanapāla seems to have been defeated by Vijayasena some time after the year 1108 A.D., which is the probable date of his Manahali inscription, when Candradeva was dead. Candradeva must have died before 1104 A.D., as in that year the Basāhi Plates of his grandson Govinda-Candra were issued, and that prince is styled "Mahārājaputra", so it must be admitted that Candradeva had ceased to reign at that time, and his son Madanpāla sat on the throne.[5]
