Maharaja Gemunu

Dutugamunu also known as Dutthagamani and Gamani Abhaya ("fearless Gamini"), was a Sinhalese king of Sri Lanka who reigned from 161 BC to 137 BC. He is renowned for defeating and overthrowing Elara, the usurping Tamil prince from the Chola Kingdom, who had invaded the Kingdom of Rajarata in 205 BC. Dutugamunu also expanded and beautified the city of Anuradhapura and projected the power of his native Rajarata region across the island of Sri Lanka.
