Kashmir is located in the northwestern region of South Asia and includes the Indian state of Jammu and Kashmir, the Pakistan-administered territories of Azad Kashmir and Gilgit-Baltistan, and the Chinese-administered regions of Aksai Chin and the Trans-Karakoram Tract. The origin of the Kashmiri people is shrouded in mystery; there are various theories that have been put forward in this regard. According to one of the theories, the initial settlers in Kashmir were Aryans who migrated from Central Asia. These people were a long headed race of tall structure with narrow noses and fair complexion. Another theory of the Kashmiri descent posts that the Kashmiri people of India and Pakistan originally descended from the Ten Lost Tribes of ancient Israel.
