Explanations:The Anuradhapura Kingdom was a powerful and influential kingdom in ancient Sri Lanka, known for its rich cultural and religious heritage. The kingdom was primarily ruled by Sinhalese kings, but it also had a significant period under Tamil rule. The first Tamil ruler of the Anuradhapura Kingdom was Ellalan, also known as Elara, who reigned from 205 to 161 BCE.
Ellalan was a Chola prince from South India who came to power in Sri Lanka after a successful invasion. His reign is notable for several reasons. Firstly, he was a just and fair ruler, known for his equitable administration and the establishment of a legal system that was respected even by his adversaries. Secondly, he was a patron of Buddhism, despite being a Tamil ruler, and he is said to have built several Buddhist monasteries and temples.
Ellalan's reign marked a significant period in the history of Sri Lanka, as it brought about a blend of Tamil and Sinhalese cultures. His rule was eventually challenged by the Sinhalese king Dutugemunu, who defeated Ellalan in a famous battle. Despite this, Ellalan's legacy as a just and fair ruler is remembered in Sri Lankan history.
