Prior to Chandragupta's
consolidation of power, small regional
kingdoms dominated the northwestern
subcontinent, while the Nanda Dynasty
dominated the middle and lower basin of the
Ganges. After Chan dragupta's conquests, the
Maurya Empire extended from Bengal and
Assam in the east, to Afghanistan and
Balochistan, some part of the eastern and south-
eastern in the west, to Kashmir and Nepal in the
north, and to the Deccan Plateau in the south.
The vast empire extended from the Bay of
Bengal in the east to the Indus River in the west
