Kashmir (/ˈkæʃmɪər/ KASH-meer or /kæʃˈmɪər/ kash-MEER) 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.

A territorial dispute or boundary dispute is a disagreement over the possession or control of territories (land, water or airspace) between two or more political entities.

Ladakh (English: /ləˈdɑːk/, Hindi: [ləd̪ːaːx]) is a region administered by India as a union territory and constitutes an eastern portion of the larger Kashmir region that has been the subject of a dispute between India and Pakistan since 1947 and India and China since 1959. Ladakh is bordered by the Tibet Autonomous Region to the east, the Indian state of Himachal Pradesh to the south, both the Indian-administered union territory of Jammu and Kashmir and the Pakistan-administered Gilgit-Baltistan to the west, and the southwest corner of Xinjiang across the Karakoram Pass in the far north. It extends from the Siachen Glacier in the Karakoram range to the north to the main Great Himalayas to the south. The eastern end, consisting of the uninhabited Aksai Chin plains, is claimed by the Indian Government as part of Ladakh, but has been under Chinese control.

In the past, Ladakh gained importance from its strategic location at the crossroads of important trade routes, but as Chinese authorities closed the borders between Tibet Autonomous Region and Ladakh in the 1960s, international trade dwindled. Since 1974, the Government of India has successfully encouraged tourism in Ladakh. As Ladakh is strategically important, the Indian military maintains a strong presence in the region.

The Karakoram (/ˌkɑːrəˈkɔːrəm, ˌkær-/) is a mountain range in Asia located primarily in the Kashmir region. The range spans the borders of Pakistan, China, and India, with the north-western extremities of the range extending into Afghanistan and Tajikistan. The Karakoram contains four of the fourteen eight-thousanders, the highest of which is K2, the second highest mountain on Earth.

The Karakoram begins in the Wakhan Corridor in western Afghanistan and extends eastwards into Indian-administered Ladakh and Chinese-administered Aksai Chin, as well as the Chinese province of Xinjiang. Most of the Karakoram is located within the Pakistani-administered Gilgit-Baltistan region. The Karakoram is bounded on the east by the Aksai Chin plateau, on the north-east by the edge of the Tibetan Plateau, and on the north by the river valleys of the Yarkand and Karakash rivers, beyond which lie the Kunlun Mountains. At the north-west corner are the Pamir Mountains. The southern boundary of the Karakoram is formed west to east by the Gilgit, Indus, and Shyok rivers, which separate the range from the north-western end of the Himalaya. These rivers flow north-west before making an abrupt turn south-westwards towards the plains of Pakistan. Roughly in the middle of the Karakoram range is the Karakoram Pass, which was part of a now unused trade route between Ladakh and Yarkand.

The Line of Actual Control (LAC), in the context of the Sino-Indian border dispute, is a notional demarcation linethat separates Indian-controlled territory from Chinese-controlled territory on their mutual border. The concept was introduced by Chinese premier Zhou Enlai in a 1959 letter to Jawaharlal Nehru as the "line up to which each side exercises actual control", but rejected by Nehru as being incoherent. Subsequently, the term came to refer to the line formed after the 1962 Sino-Indian War.

The LAC is different from the borders claimed by each country in the Sino-Indian border dispute. The Indian claims include the entire Aksai Chin region and the Chinese claims include Arunachal Pradesh/Zangnan. These claims are not included in the concept of "actual control".

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.

After the Government of India repealed the special status accorded to Jammu and Kashmir under Article 370 of the Indian constitution in 2019, the Parliament of India passed the Jammu and Kashmir Reorganisation Act, which contained provisions to split the state into two union territories – Ladakh in the east and the residuary Jammu and Kashmir in the west, with effect from 31 October 2019. Jammu and Kashmir was the only state in India with a Muslim-majority population.

In 1819, the Sikh Empire, under Ranjit Singh, annexed the Kashmir valley. In 1846, after the Sikh defeat in the First Anglo-Sikh War, and upon the purchase of the region from the British under the Treaty of Amritsar, the Raja of Jammu, Gulab Singh, became the new ruler of Jammu and Kashmir. The rule of his descendants, under the paramountcy (or tutelage) of the British Crown, lasted until the Partition of India in 1947, when the former princely state of the British Indian Empire became a disputed territory, now administered by three countries: China, India, and Pakistan.
