Rajatarangini, written by the Kashmiri historian Kalhana in the 12th century CE, consists of around 7,826 verses, which is approximately 9,000 slokas. This work, written in Sanskrit, provides a detailed chronicle of the history of Kashmir from its mythical origins to Kalhana’s contemporary period. Kalhana’s work is considered one of the earliest and most detailed historical accounts of any region in India, combining both legend and documented history. The Rajatarangini is divided into eight books, or “tarangas,” and remains a critical source for understanding early medieval Indian history, particularly in relation to Kashmir.
