After Dhatusena, Kassapa and Mogallana, which were the first rulers of the Moriya dynasty and very famous as antagonists of the Sigiriya story, the history of the Anuradhapura kingdom starts to be dull in the extreme in the 6th century. Short-lived reigns and revolts were predominant.
The ten years following the death of Moggallana saw five ephemeral kings on the throne. One civil war was followed by another only a decade later. One reason seems to have been the rivalry between the two royal lineages, the Moriyas and the Lambakannas.
One remarkable king of this troubled period was Silakala (526-39), because he introduced a new system of regional control by handing over the administration of two provinces of the Anuradhapura kingdom to his elder sons, retaining the surroundings of Anuradhapura for himself. To his eldest son Moggallana he granted the division to the east of the capital, whereas Dakkhinadesa, situated to the south of Anuradhapura, namely in today’s North Western Province, went to his second son, who could from now on control the western sea-coast.
Only two decades later, there were finally four units of the Anuradhapura Kingdom, called Rajarata, “King’s Land” those days:
Uttaradesa was the northern division, “Uttara” meaning “north” and “desa” meaning “land”.
Paccimadesa was the western division, Pachinadesa the eastern division, Dakkhinadesa, the already mentioned southern division, as the largest in size. Later in, the heir to the throne was the adminstrator of this southern division.
