Rajatarangini (Rājataraṃgiṇī, "The River of Kings") is a metrical legendary and historical chronicle of the north-western Indian subcontinent, particularly the kings of Kashmir. It was written in Sanskrit by Kashmiri historian Kalhana in the 12th century CE. The work consists of 7826 verses, which are divided into eight books called Tarangas ("waves").
The Rajataringini provides the earliest source on Kashmir that can be labeled as a "historical" text on this region. Although inaccurate in its chronology, the book still provides an invaluable source of information about early Kashmir and its neighbors in the north western parts of the Indian subcontinent, and has been widely referenced by later historians and ethnographers.
Little is known about the author Kalhana (c. 12th century CE), apart from what is written in the book. His father Champaka was the minister (Lord of the Gate) in the court of Harsha of Kashmir. In the first Taranga (book) of Rajatarangini, Kalhana expresses his dissatisfaction with the earlier historical books, and presents his own views on how history ought to be written:
Despite these stated principles, Kalhana's work is also full of legends and inconsistencies (see Historical reliability below).
The kings of Kashmir described in the Rajatarangini are given below. Notes in parentheses refer to a book ("Taranga") and verse. Thus (IV.678) is Book IV verse 678. The summary is from J.C. Dutt's translation. Kalhana's work uses Kali and Laukika (or Saptarishi) calendar eras: the ascension year in CE, as given below, has been calculated by Dutt based on Kalhana's records.
Kalhana mentions that Gonanda I ascended the throne in 653 Kali calendar era. According to Jogesh Chander Dutt's calculation, this year corresponds to 2448 BCE. The total reign of the following kings is mentioned as 1266 years.
The Gonanditya dynasty ruled Kashmir for 1002 years.
No kings mentioned in this book have been traced in any other historical source. These kings ruled Kashmir for 192 years.
After a young son of Yashaskara, Pravaragupta, a Divira (clerk), became king. His son Kshemagupta married Didda, daughter of Simharaja of Lohara. After ruling indirectly and directly, Didda (980-1003 CE) placed Samgramaraja, son of her brother on the throne, starting the Lohara dynasty.
