Jammu and Kashmir was a region formerly administered by India as a state from 1952 to 2019, constituting the southern and southeastern portion of the larger Kashmir region, which has been the subject of a dispute between India, Pakistan and China since the mid-20th century. The underlying region of this state were parts of the former princely state of Jammu and Kashmir, whose western districts, now known as Azad Kashmir, and northern territories, now known as Gilgit-Baltistan, are administered by Pakistan. The Aksai Chin region in the east, bordering Tibet, has been under Chinese control since 1962.

Azad Jammu and Kashmir abbreviated as AJK and colloquially referred to as simply Azad Kashmir, is a region administered by Pakistan as a nominally self-governing entity and constituting the western portion of the larger Kashmir region, which has been the subject of a dispute between India and Pakistan since 1947. Azad Kashmir also shares borders with the Pakistani provinces of Punjab and Khyber Pakhtunkhwa to the south and west, respectively. On its eastern side, Azad Kashmir is separated from the Indian union territory of Jammu and Kashmir by the Line of Control (LoC), which serves as the de facto border between the Indian- and Pakistani-controlled parts of Kashmir. Geographically, it covers a total area of 13,297 km2 (5,134 sq mi) and has a total population of 4,045,366 as per the 2017 national census.
