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 come to encompass a larger area that includes the India-administered territories of Jammu and Kashmir and Ladakh, the Pakistan-administered territories of Azad Kashmir and Gilgit-Baltistan, and the Chinese-administered territories of Aksai Chin and the Trans-Karakoram Tract.
