Kalhana's Rajatarangini, a historical chronicle of Kashmir, concludes with the reign of King Jayasimha (1120-1150 CE). Jonaraja wrote the 'Dwitiya Rajatarangini', which continued the history of Kashmir from where Kalhana left off, narrating events up to the early years of the reign of Sultan Zain-ul-Abidin (who ruled from 1420 to 1470 CE).
