What is "jalauka"

Jalauka (also known as Jaluka) was, according to the 12th century Kashmiri chronicle, the Rajatarangini, a king of Kashmir. Jaluka was reputed to have been an active and vigorous king of Kashmir, who expelled certain intrusive foreigners, and conquered the plains as far as Kannauj. Jalauka was hostile towards Buddhism and devoted to the worship of the Hindu god Shiva and the Divine Mothers, in whose honour he and his queen, Isana-devi, erected many temples in places which can be identified.
