Union territory in the context of "Ten Degree Channel"

Northwest India is a loosely defined region of India. In modern-day, it consists of north-western states of the Republic of India. In historical contexts, it refers to the northwestern Indian subcontinent (including modern-day Pakistan).

In contemporary definition, it generally includes the states of Haryana, Himachal Pradesh, Punjab, Rajasthan Uttarakhand, and often Uttar Pradesh, along with the union territories of Chandigarh, Jammu and Kashmir, Ladakh, and the National Capital Territory of Delhi. Gujarat, a western coastal state, is occasionally included as well. The mountainous upper portion of Northwest India consists of the Western Himalayas, while the flat lower portion consists of the middle portion of the Indo-Gangetic plains and the Thar Desert.

Jammu and Kashmir (abbr. J&K) is a region administered by India as a union territory and consists of the southern portion of the larger Kashmir region, which has been the subject of a dispute between India and Pakistan since 1947 and between India and China since 1959.

The Line of Control separates Jammu and Kashmir from the Pakistani-administered territories of Azad Kashmir and Gilgit-Baltistan in the west and north respectively. It lies to the north of the Indian states of Himachal Pradesh and Punjab and to the west of Ladakh which is administered by India as a union territory. Insurgency in Jammu and Kashmir has persisted in protest over autonomy and rights. In 2019, the Jammu and Kashmir Reorganisation Act was passed, reconstituting the former state of Jammu and Kashmir into two union territories: Ladakh in the east and the residuary Jammu and Kashmir in the west.

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.

Aksai Chin is a region administered by China partly in He'an County and Hekang County of Hotan Prefecture, Xinjiang, and partly in Rutog County of Ngari Prefecture, Tibet, and constituting the easternmost portion of the larger Kashmir region that has been the subject of a dispute between India and China since 1959. China administers the region and claims it as part of the Xinjiang and Tibet autonomous regions. India meanwhile claims it as part of Leh district in the union territory of Ladakh.

Modern Standard Hindi (आधुनिक मानक हिन्दी, Hunterian: Ādhunik Mānak Hindī), commonly referred to as Hindi, is an Indo-Aryan language written in the Devanagari script. It is an official language of the Government of India, and is the lingua franca of most of the country. It is also an official language in the Pacific nation of Fiji.

Hindi is an official language in ten states (Bihar, Chhattisgarh, Gujarat, Haryana, Himachal Pradesh, Jharkhand, Madhya Pradesh, Rajasthan, Uttar Pradesh, Uttarakhand), and six union territories (Andaman and Nicobar Islands, Delhi, Chandigarh, Dadra and Nagar Haveli and Daman and Diu, Ladakh and Jammu and Kashmir) and an additional official language in the state of West Bengal. Hindi is also one of the 22 scheduled languages of the Republic of India.

The Punjab Plain is a large alluvial plain in northwestern India and eastern Pakistan. The plain includes the Indian states of Punjab and Haryana and the union territory of Delhi, excluding the Shahdara district, and the eastern part of Pakistani Punjab. This plain is around 200–300 meters above mean sea level. The plain is the western part of the Indo-Gangetic Plain, and is bounded by the Sivalik Hills in the north, the Yamuna River in the east, the Thar Desert of Rajasthan to the south, the Ravi River to the northwest and Sutlej River to the southwest. The plain is extensively farmed for cereals and cotton.

The land formed of alluvium in between two rivers known as Doab is found here. 'Doab' is made up of two words — 'do' meaning two and 'ab' meaning water. Similarly 'Punjab', is also made up of two words — 'Punj' meaning five and 'ab' meaning water.

Himachal Pradesh (Hindi: Himācal Pradeś, pronounced [ɦɪˈmäːtʃəl pɾəˈd̪eːʃ]; Sanskrit: himācāl prādes; lit. "Snow-laden Mountain Province") is a state in the northern part of India. Situated in the Western Himalayas, it is one of the 13 mountain states and is characterised by an extreme landscape featuring several peaks and extensive river systems. Himachal Pradesh is the northernmost state of India and shares borders with the union territories of Jammu and Kashmir and Ladakh to the north, and the states of Punjab to the west, Haryana to the southwest, Uttarakhand to the southeast and a very narrow border with Uttar Pradesh to the south. The state also shares an international border to the east with the Tibet Autonomous Region in China. Himachal Pradesh is also known as Dev Bhoomi, meaning 'Land of Gods' and Veer Bhoomi which means 'Land of the Brave'.

The predominantly mountainous region comprising the present-day Himachal Pradesh has been inhabited since pre-historic times, having witnessed multiple waves of human migrations from other areas. Through its history, the region was mostly ruled by local kingdoms, some of which accepted the suzerainty of larger empires. Prior to India's independence from the British, Himachal comprised the hilly regions of the Punjab Province of British India. After independence, many of the hilly territories were organised as the Chief Commissioner's province of Himachal Pradesh, which later became a Union Territory. In 1966, hilly areas of the neighbouring Punjab state were merged into Himachal and it was ultimately granted full statehood in 1971.

Tamil Nadu is the southernmost state of India. The tenth largest Indian state by area and the sixth largest by population, Tamil Nadu is the home of the Tamil people, who speak the Tamil language—the state's official language and the first to be recognised as a classical language in India. The capital and largest city is Chennai.

Located on the south-eastern coast of the Indian peninsula, Tamil Nadu is straddled by the Western Ghats and Deccan Plateau in the west, the Eastern Ghats in the north, the Eastern Coastal Plains lining the Bay of Bengal in the east, the Gulf of Mannar and the Palk Strait to the south-east, the Laccadive Sea at the southern cape of the peninsula, with the river Kaveri bisecting the state. Politically, Tamil Nadu is bound by the Indian states of Kerala, Karnataka, and Andhra Pradesh, and encloses a part of the union territory of Puducherry. It shares an international maritime border with the Northern Province of Sri Lanka at Pamban Island.

The Andaman and Nicobar Islands is a union territory of India comprising 836 islands, of which only 31 are inhabited. The islands are grouped into two main clusters: the northern Andaman Islands and the southern Nicobar Islands, separated by a 150 km (93 mi) wide channel. The capital and largest city of the territory, Port Blair (officially Sri Vijaya Puram), is located approximately 1,190 km (740 mi) from Chennai and 1,255 km (780 mi) from Kolkata in mainland India. The islands are situated between the Bay of Bengal to the west and the Andaman Sea to the east. The northernmost point is 901 km (560 mi) from the mouth of the Hooghly River. Indira Point, located at 6°45'10″N and 93°49'36″E on the southern tip of Great Nicobar, is the southernmost point of India.

The territory shares maritime borders with Indonesia located about 165 km (103 mi) to the south, Myanmar located 280 km (170 mi) to the north-east and Thailand located 650 km (400 mi) to the south-east. The islands occupy a total land area of approximately 8,249 km (3,185 sq mi) with a population of 380,581 as per the 2011 census. The territory is divided into three districts: Nicobar, South Andaman, and North and Middle Andaman with the capitals at Car Nicobar, Port Blair and Mayabunder respectively.

The Tamils (/ˈtæmɪlz, ˈtɑː-/ TAM-ilz, TAHM-), also known by their demonym Tamilar, are a Dravidian ethnic group who natively speak the Tamil language and trace their ancestry mainly to the southern part of the Indian subcontinent. Tamil is one of the longest-surviving languages, with over two thousand years of written history, dating back to the Sangam period (between 300 BCE and 300 CE).

Tamils constitute about 5.7% of the Indian population and form the majority in the South Indian state of Tamil Nadu and the union territory of Puducherry. They also form significant proportions of the populations in Sri Lanka (15.3%), Malaysia (7%) and Singapore (5%). Tamils have migrated world-wide since the 19th century CE and a significant population exists in South Africa, Mauritius, Fiji, as well as other regions such as the Southeast Asia, Middle East, Caribbean and parts of the Western World.
