When Kingdom of Kotte was divided due to the incident known as "Wijayaba Kollaya", which resulted in the assassination of king Vijayabahu, Pararajasinghe became the ruler of Raigama.
Raigam Bandara was known as a good ruler who upheld the economy of the Raigama.
However, after a battle with the Kingdom of Kotte the family of Raigam Bandara had fled to Matara as a result of miscommunication.
The only descendants of the king still live bearing the name of "Mohotti" in Matara and in North Central province.
After Raigama Bandara's death in 1538, his brother Mayadunne, ruler of Sitawaka, annexed the kingdom of Raigam.
