Which ruler succeeded his father and continued to expand territory by conquering twelve rulers in south india?

Samudragupta, ruler of the Gupta Empire (c. AD 335 - 375), and successor to Chandragupta I, is considered to be one of the greatest military geniuses in Indian history. He passed through the forest tracts of Madhya Pradesh, crossed the Orissa coast, marched through 12 or more districts and may have reached as far as Kancheepuram.

It is said that Samudragupta became the ruler after subduing his rival, Kacha, an obscure prince of the dynasty. Samudragupta is depicted on his coins both as a muscular warrior flaunting the "marks of hundreds of wounds received in battle" as well as a poet and a musician.
