Pataliputra was of central importance during the Mauryan Empire because it served as the imperial capital and the administrative heart of the state. Located near the strategic junction of the Son and Ganges rivers, the city allowed the empire to control vital communication and trade routes throughout the region.12

As the seat of government, Pataliputra was the hub for the empire’s highly organized bureaucracy and civil service, which managed a vast territory encompassing nearly the entire Indian subcontinent. The city’s prestige was further bolstered by its role as a center of political power for the Magadha kingdom, which provided the nucleus for Mauryan expansion. During the reign of Ashoka, Pataliputra functioned as the base from which he governed his vast realm and directed the spread of Buddhism across Asia following his conversion.21
