Kashyapa I, also known as Kasyapa I or Kassapa I, was a king of Sri Lanka, who ruled the country from 473 to 495 CE.
He was later defeated by Moggallana, who had fled to South India and returned with an army to regain the throne.
Assisted and encouraged by Migara, Kashyapa carried out a palace coup and overthrew Dhatusena.
Dhatusena took his captors to the Kala wewa, a large irrigation tank he had constructed, and told him that it was the only treasure he had.
[6] Sigiriya was a large rock rising above the surrounding plain, offering an unhindered view in all directions.
Moggallana organised an army in South India and returned to Sri Lanka to claim his right to the throne.
The king tried a tactical move on his war elephant, which his troops interpreted as retreating, and abandoned him.
