Explanation:

Although the Shakas established their rule in different parts of the country, only those who ruled in western India held power for any considerable length of time, for about four centuries or so. They benefited from the sea-borne trade in Gujarat and issued numerous silver coins.
The most famous Shaka ruler in India was Rudradaman I (AD 130–50). He ruled not only over Sindh, but also over a substantial part of Gujarat, Konkan, the Narmada valley, Malwa, and Kathiawar.
He is famous in history because of the repairs he undertook to improve the Sudarshana lake in the semi-arid zone of Kathiawar which had been in use fo irrigation for a long time and dated back to the Mauryas.
Rudradaman was a great lover of Sanskrit. Although he had Central Asian ancestors, he issued the first-ever long inscription in chaste Sanskrit. All the earlier longer inscriptions that we have in India were composed in Prakrit which had been made the state language by Ashoka.
