irimeghavanna, also known as Kirthi Sri Meghavarna and Kithsirimevan was King of Anuradhapura in the 4th century, whose reign lasted from 304 to 332. He succeeded his father Mahasena as King of Anuradhapura and was succeeded by his brother Jettha Tissa II.

 

The sacred relic of the tooth of the Buddha was brought to Sri Lanka during the reign of this king[2] who welcomed it with great respect, ushered them to his capital and enshrined it in Meghagiri Viharaya, presently known as Isurumuniya in Anuradhapura. In order to honor the sacred tooth relic, an annual procession called dalada perahera begins from the era of this king.
