The Lohara dynasty were Hindu rulers of Kashmir in the northern part of the Indian subcontinent, between 1003 and approximately 1320 CE. The early history of the dynasty was described in the Rajatarangini (Chronicle of Kings), a work written by Kalhana in the mid-12th century and upon which many and perhaps all studies of the first 150 years of the dynasty depend. Subsequent accounts, which provide information up to and beyond the end of the dynasty come from Jonarāja and Śrīvara. The later rulers of the dynasty were weak: internecine fighting and corruption was endemic during this period, with only brief years of respite, making the dynasty vulnerable to the growth of Islamic onslaughts in the region.
