Much is written of the war of 205 BC to 161 BC between Sinhala King Dutugemunu and Ellalan for the city of Anuradhapura, and the central role played by Dutugemunu's Ten Giant Warriors or Ten Great Giants. According to the chronicle Mahavamsa the men were drafted into Royal service during the reign of Dutugemunu's father, King Kavantissa.

Dutugamunu the Great, also known as Duṭṭhagāmaṇī Abhaya, was a king of the Anuradhapura Kingdom who reigned from 161 BC to 137 BC. He is renowned for first uniting the whole island of Sri Lanka by defeating and overthrowing Elara, a Tamil trader from the Chola Kingdom, who had invaded the Anuradhapura kingdom in 205 BC. Dutugamunu also expanded and beautified the city of Anuradhapura and projected the power of the Rajarata kingdom across the island of Sri Lanka.
