When King Nissankamalla (1187-1196) died his son Virabahu II, ruled for one night and was assassinated. Nissankamalla's younger brother VikkamaBahu II (1196) mounted the throne for three months; until slain by his sister's son Colaganga (1196-1197) who ruled for nine months. The powerful general Kitti had the eyes of this king put out, deposed him and had the government carried on for three years without mishap by Queen Lilavati (1197-1200), the first mahesi of the great King Parakkamabahu (1153-1186). Thereupon King Sahasamalla (1200-1202) of the race of Okkaka, carried on the government for two years. Then having deposed this Monarch, the general Ayasmanta, had the government carried on by Kalyanavati (1202-1208), the first mahesi of Nissankamalla. Thereupon there reigned for one year a royal prince Dhammasoka (1208-1209), who on coming to the throne was aged three months. The Mahadipada Anikanga (1209) came at the head of a great army from the Chola kingdom, slew Prince Dhammasoka in Polonnaruva, together with the general Ayasmanta, but reigned only seventeen days. The general, Vikkantacamunakka, slew Anikanga and had the government carried on for a year by Lilavati (1209-1210), who had already reigned before. For nine months Lanka was ruled by Lokesvara (1210-1211) who came with a Dhamila army from the opposite shore. He was removed by general Parakkama who consecrated the Mahesi Lilavati (1211) once again. After about seven months had passed, there landed with a Pandu army the King Parakkama Pandu (1211-1214), deposed the Queen and her general and after he had cleared Lanka from the briers (of revolt), ruled the realm in Polonnaruva for three years.
