Kashmir is the northernmost geographical region of the Indian subcontinent. Until the mid-19th century, the term Kashmir denoted only the Kashmir Valley between the Great Himalayas and the Pir Panjal Range. The term has since also come to encompass a larger area that formerly comprised the princely state of Jammu and Kashmir, and includes the Indian-administered territories of Jammu and Kashmir and Ladakh, the Pakistani-administered territories of Azad Kashmir and Gilgit-Baltistan, and the Chinese-administered territories of Aksai Chin and the Trans-Karakoram Tract.
