The Sinhala Kingdom or Sinhalese Kingdom refers to the one and or all of the successive Sinhalese kingdoms that existed in what is today Sri Lanka. Founded in 543 BC, the Sinhala Kingdom existed as successive kingdoms known by the city at which its administrative centre was located. These are in chronological order: the kingdoms of Tambapanni, Upatissa Nuwara, Anuradhapura, Polonnaruwa, Dambadeniya, Gampola, Kotte, Sitawaka and Kandy. The Sinhala Kingdom ceased to exist by 1815. During the period in which the Sinhala Kingdom existed, other political entities also existed in Sri Lanka, including the Jaffna kingdom,Vanni chieftaincies and the Portuguese and Dutch colonies. However, these political entities were not part of the Sinhala Kingdom.
*Mahabharata, Book 1, Chapter 177
When the sage Vasistha was attacked by king Viswamitra's army, Vasistha's cow, Kamadehnu, brought forth from her tail, an army of Pallavas, and from her udders, an army of Dravidas and Sakas; and from her womb, an army of Yavanas, and from her dung, an army of Savaras; and from her urine, an army of Kanchis; and from her sides, an army of Savaras. And from the froth of her mouth came out hosts of Paundras and Kiratas, Yavanas and Sinhalas, and the barbarous tribes of Khasas and Chivukas and Pulindas and Chinas and Hunas with Keralas,and numerous other Mlechchhas.
