The invasion was successful; the Lichchhavi capital, Vaisali, was occupied, and Ajatasatru became master of his maternal grandfather's territory. It is probable that the invader carried his victorious arms to their natural limit, the foot of the mountains, and that from this time the whole region between the Ganges and the Himalaya became subject, more or less directly, to the suzerainty of Magadha.
The victor erected a fortress at the village of Patali on the bank of the Ganges to curb his Lichchhavi opponents. The foundations of a city nestling under the shelter of the fortress were laid by his grandson Udaya. The city so founded was known variously as Kusumapura, Pushpapura, or Pataliputra, and rapidly developed in size and magnificence, until, under the Maurya dynasty, it became the capital, not only of Magadha, but of India.
