Gujjars are hypothesized to be descended from the nomadic Khazar one of the Scythian-Aryan tribes that invaded the subcontinent in the 4th century. Their conquests largely amounted to the Gujarat, Punjab and Kashmir regions, where they settled and merged with the local Indo-Aryan population. Much of the population of present day Afghanistan, Pakistan and Northwestern India can claim its ancestry from these sun-worshipping tribes, which they share with the Rajputs and Jats among others.
