These two cities had been the capital of Bengal in ancient and medieval ages. The boundary of Gour was changed in different ages since 5th century BC. Its name can be found in Puranic texts. Pundranagar was the provincial capital of Maurya Empire. Gour and Pundrabardhana formed parts of the Mourya empire as is evinced from the inscriptions, Brahmilipi on a seal discovered from the ruins of Mahasthangarh in the Bogra District of Bangladesh. Hiuen Tsang saw many Ashokan stupas at Pundrabardhana. The inscriptions discovered in the district of undivided Dinajpur and other parts of North Bengal along with the Allahabad Pillar inscriptions of Samudragupta clearly indicate that the whole of North Bengal as far east as Kamrup formed a part of the Gupta empire.
