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. Today, it denotes a larger area that includes the Indian-administered territory of Jammu and Kashmir (which includes the region of Jammu, Kashmir Valley, Ladakh and Siachen), the Pakistani-administered territories of Azad Kashmir and Gilgit-Baltistan, and Chinese-administered territories of Aksai Chin and the Trans-Karakoram Tract
