Explanation:

 In the 6th century BCE Mathura became the capital of the Surasena mahajanapada. The city was later ruled by the Maurya empire (4th to 2nd centuries BC) and the Shunga dynasty (2nd century BC). It may have come under the control of Indo-Greeks some time between 180 BCE and 100 BC. It then reverted to local rule before being conquered by the Indo-Scythians during the 1st century BC.
