Which work, composed by Kalhana in the twelfth century, is a chronicle of the kings of Kashmir?

Rajatarangini, written by Kalhana around 1148 CE, is regarded as one of the earliest works in Sanskrit with a historical approach, tracing the rulers of Kashmir up to his own time. Harshacharita is Banabhatta's biography of Harsha, Mudrarakshasa is Vishakhadatta's play on Chanakya and Chandragupta Maurya, and the Ashtadhyayi is Panini's grammar text, so none of these is a regional chronicle.
