Gujarat (Gujarati: Gujarāt, pronounced [ˈɡudʒəɾaːt] ) is a state along the western coast of India. Its coastline of about 2,340 km (1,450 mi) is the longest in the country, most of which lies on the Kathiawar peninsula. Gujarat is the fifth-largest Indian state by area, covering some 196,024 km (75,685 sq mi); and the ninth-most populous state, with a population of 60.4 million in 2011. It is bordered by Rajasthan to the northeast, Dadra and Nagar Haveli and Daman and Diu to the south, Maharashtra to the southeast, Madhya Pradesh to the east, and the Arabian Sea and the Pakistani province of Sindh to the west. Gujarat's capital city is Gandhinagar, while its largest city is Ahmedabad. The Gujaratis are indigenous to the state, and their language, Gujarati, is the state's official language.

The state encompasses 23 sites of the ancient Indus Valley Civilisation (more than any other state). The most important sites are Lothal (the world's first dry dock), Dholavira (the fifth largest site), and Gola Dhoro (where five uncommon seals were found). Lothal is believed to have been one of the world's first seaports. Gujarat's coastal cities, chiefly Bharuch and Khambhat, served as ports and trading centres in the Maurya and Gupta empires, and during the succession of royal Saka dynasties in the Western Satraps era.Along with Bihar, Mizoram and Nagaland, Gujarat is one of four Indian states to prohibit the sale of alcohol. The Gir National Park in Gujarat is home to the only wild population of the Asiatic lion in the world.

Christianity is India's third-most followed religion with 28 million adherents, who make up 2.3 percent of the population as of the 2011 census. Christianity is the largest religion in parts of Northeast India, specifically in Nagaland, Mizoram, and Meghalaya. It is also a significant religion in Manipur, which is 41 percent Christian.

Nearly two-thirds (65 percent) of India's Christians are found in South India, Goa, & Mumbai (Bombay). The oldest known Christian group in North India are the Hindustani-speaking Bettiah Christians of Bihar, formed in the early 1700s through a Capuchin mission and under the patronage of Rajas (kings) in the Moghal Empire. The Church of North India and the Church of South India are a United Protestant denomination; which resulted from the evangelism/ ecumenism of Anglicans, Calvinists, Methodists and other Protestant groups who flourished in colonial India. Consequently, these churches are part of the worldwide Anglican Communion, World Communion of Reformed Churches, and World Methodist Council. Along with native Christians, small numbers of mixed Eurasian peoples such as Anglo-Indian, Luso-Indian, Franco-Indian and Armenian Indian Christians also existed in the subcontinent. Also, there is the Khrista Bhakta movement, who are unbaptised followers of Christ and St Mary, mainly among the Shudras and Dalits.

Assam is a state in northeastern India, south of the eastern Himalayas along the Brahmaputra and Barak River valleys. Assam covers an area of 78,438 km (30,285 sq mi). It is the second largest state in northeastern India by area and the largest in terms of population, with more than 31 million inhabitants. The state is bordered by Bhutan and Arunachal Pradesh to the north; Nagaland and Manipur to the east; Meghalaya, Tripura, Mizoram and Bangladesh to the south; and West Bengal to the west via the Siliguri Corridor, a 22-kilometre-wide (14 mi) strip of land that connects the state to the rest of India. Assamese and Bodo are two of the official languages for the entire state and Meitei (Manipuri) is recognised as an additional official language in three districts of Barak Valley and Hojai district. in Hojai district and for the Barak Valley region, alongside Bengali, which is also an official language in the Barak Valley.

The state has 35 districts with 5 divisions. Guwahati (containing the state capital Dispur) is the largest city in northeastern India. Assam is known for Assam tea and Assam silk. The state was the first site for oil drilling in Asia. Assam is home to the one-horned Indian rhinoceros, along with the wild water buffalo, pygmy hog, tiger and various species of Asiatic birds, and provides one of the last wild habitats for the Asian elephant. The Assamese economy is aided by wildlife tourism to Kaziranga National Park and Manas National Park, which are World Heritage Sites. Dibru-Saikhowa National Park is famed for its feral horses. Sal tree forests are found in the state which, as a result of abundant rainfall, look green all year round. Assam receives more rainfall than most parts of India; this rain feeds the Brahmaputra River, whose tributaries and oxbow lakes provide the region with a distinctive hydro-geomorphic environment.

The Bangladesh–India border, known locally as the Radcliffe line, is an international border running between the republics of Bangladesh and India. Six Bangladeshi divisions and five Indian states lie along the border.

Bangladesh and India share a 4,096-kilometre-long (2,545 mi) international border, the sixth-longest land border in the world, including 262 km (163 mi) in Assam, 856 km (532 mi) in Tripura, 318 km (198 mi) in Mizoram, 443 km (275 mi) in Meghalaya and 2,217 km (1,378 mi) in West Bengal. The Bangladeshi divisions of Mymensingh, Khulna, Rajshahi, Rangpur, Sylhet, and Chittagong are situated along the border. A number of pillars mark the border between the two states. Small demarcated portions of the border are fenced on both sides.

Northeast India, officially the North Eastern Region (NER), is the easternmost region of India representing both a geographic and political administrative division of the country. It comprises eight states: Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, and Tripura (commonly known as the "Seven Sisters"), and the "Brother" state of Sikkim. North-east India is one of the most linguistically diverse regions in the world.

The region has India's international border of 5,182 kilometres (3,220 mi) with five neighbouring countries: China to the north, Myanmar to the east, Bangladesh to the southwest, Nepal to the west, and Bhutan to the northwest. It comprises an area of 262,184 square kilometres (101,230 sq mi), almost 8 per cent of that of India and has a population of 45,772,188, almost 4 per cent that of India. The Siliguri Corridor connects the region to other parts of India.

Nepali (नेपाली, Nepālī, [ˈnepali]), is an Indo-Aryan language, belonging to the Indo-Iranian branch of the Indo-European language family, native to the Himalayan region of South Asia. It is the official and most-widely spoken language of Nepal, where it also serves as a lingua franca. Nepali has official status in the Indian state of Sikkim and in the Gorkhaland Territorial Administration semi-autonomous region of West Bengal, where it is the majority language. It is also spoken by about a quarter of Bhutan's population. Nepali also has a significant number of speakers in the Indian states of Arunachal Pradesh, Assam, Himachal Pradesh, Manipur, Meghalaya, Mizoram and Uttarakhand. In Myanmar it is spoken by the Burmese Gurkhas. The Nepali diaspora in the Middle East, Brunei, Australia and worldwide also use the language. Nepali is spoken by approximately 19 million native speakers and another 14 million as a second language.

Nepali is commonly classified within the Eastern Pahari group of the Northern zone of Indo-Aryan.The language originated from the Sinja Valley, Karnali Province then the capital city of the Khasa Kingdom around the 10th and 14th centuries. It developed proximity to a number of Indo-Aryan languages, most significantly to other Pahari languages. Nepali was originally spoken by the Khas people, an Indo-Aryan ethno-linguistic group native to the Himalayan region of South Asia. The earliest inscription in the Nepali language is believed to be an inscription in Dullu, Dailekh District which was written around the reign of King Bhupal Damupal around the year 981. The institutionalisation of the Nepali language arose during the rule of the Kingdom of Gorkha (later became known as the Kingdom of Nepal) in the 16th century. Over the centuries, different dialects of the Nepali language with distinct influences from Sanskrit, Maithili, Hindi, and Bengali are believed to have emerged across different regions of the current-day Nepal and Uttarakhand, making Nepali the lingua franca.

Bengalis (Bengali: বাঙ্গালী, বাঙালি [baŋgali, baŋali] ), also rendered as endonym Bangalee, are an Indo-Aryan ethnolinguistic group originating from and culturally affiliated with the Bengal region of South Asia. The current population is divided between the sovereign country Bangladesh and the Indian regions of West Bengal, Tripura, Barak Valley of Assam, Andaman and Nicobar Islands, and parts of Meghalaya, Manipur and Jharkhand. Most speak Bengali, a classical language from the Indo-Aryan language family.

Bengalis are the third-largest ethnic group in the world, after the Han Chinese and Arabs. They are the largest ethnic group within the Indo–European linguistic family and the largest ethnic group in South Asia. Apart from Bangladesh and the Indian states of West Bengal, Tripura, Manipur, and Assam's Barak Valley, Bengali-majority populations also reside in India's union territory of Andaman and Nicobar Islands, with significant populations in the Indian states of Arunachal Pradesh, Delhi, Odisha, Chhattisgarh, Jharkhand, Mizoram, Nagaland and Uttarakhand as well as Nepal's Province No. 1. The global Bengali diaspora have well-established communities in the Middle East, Pakistan, Myanmar, the United Kingdom, the United States, Malaysia, Italy, Maldives, Canada, Australia, Japan, South Korea, and Singapore.

Barak Valley is the southernmost region and administrative division of the Indian state of Assam. It is named after the Barak River, whose watershed roughly forms its northern border. The Barak valley consists of three administrative districts of Assam: Cachar, Karimganj, and Hailakandi. The main and largest city is Silchar, which seats the headquarter of Cachar district and also serves as administrative divisional office of Barak valley division. The valley is bordered by Mizoram and Tripura to the south, Bangladesh and Meghalaya to the west and Manipur to the east respectively. Once North Cachar Hills was a part of Cachar district which became a subdivision in 1951 and eventually a separate district. On 1 July 1983, Karimganj district was curved out from the eponymous subdivision of Cachar district. In 1989, the subdivision of Hailakandi was upgraded into Hailakandi district.

Tripura (/ˈtrɪpʊrə, -ərə/) is a state in northeastern India. The third-smallest state in the country, it covers 10,491 km (4,051 sq mi); and the seventh-least populous state with a population of 3.67 million. It is bordered by Assam and Mizoram to the east, and by Bangladesh to the north, south and west. Tripura is divided into 8 districts and 23 sub-divisions, where Agartala is the capital and the largest city in the state. Tripura has 19 different tribal communities with a majority Bengali population. Bengali, Kokborok, and English are the state's official languages.

The area of modern Tripura — ruled for several centuries by the Manikya Dynasty — was part of the Tripuri Kingdom (also known as Hill Tippera). It became a princely state under the British Raj during its tenure, and acceded to independent India in 1947. It merged with India in 1949 and was designated as a 'Part C State' (union territory). It became a full-fledged state of India in 1972.

Chakma (/ˈtʃɑːkmə/; autonym: 𑄌𑄋𑄴𑄟𑄳𑄦 𑄞𑄌𑄴) is an Eastern Indo-Aryan language in the branch of the Indo-Iranian languages in the Indo-European language family, whose speakers are known as the Chakma or the Daingnet people. It has nearly 1 million speakers, with 60% residing in the Chittagong Hill Tracts (CHT) in Bangladesh and 35% spread across Arunachal Pradesh, Assam, Mizoram and Tripura in India. The remaining 5% live in Myanmar. The language has it own script, the Chakma script or the ajhapat (𑄌𑄋𑄴𑄟𑄳𑄦 𑄃𑄧𑄏𑄛𑄖𑄴), which is an abugida similar other South-east Asian scripts. It is mutually intelligible with the Chittagonian language.

Similarities of the Chakma language with Sanskrit, Maghadi Prakrit and with Pali is visible referring it to be a classical language. This suggests that the Chakmas have been present in the Indian subcontinent since ancient times. Cultural exchanges with neighboring communities have led to the adoption of Indo-Aryan and Arakanese terms. Studies suggest that the language may have originally been a Tibeto-Burman language before transitioning into an Indic language. However, there are abundant of vocabularies used in the Chakma language that do belong neither to Indo-Aryan nor Tibeto-Burman linguistic group, likely originating from their ancestral language. Historically, a Mongoloid group that settled in the Himalayan foothills spoke a Tibetan-related language but gradually incorporated Aryan vocabulary.

Santali (ᱥᱟᱱᱛᱟᱲᱤ, Pronounced: [santaɽi], সাঁওতালি, ସାନ୍ତାଳୀ, सान्ताली) is a Kherwarian Munda language spoken natively by the Santal people of South Asia. It is the most widely-spoken language of the Munda subfamily of the Austroasiatic languages, related to Ho and Mundari, spoken mainly in the Indian states of Assam, Bihar, Jharkhand, Mizoram, Odisha, Tripura and West Bengal. It is one of the constitutionally scheduled official languages of the Indian Republic and the additional official language of Jharkhand and West Bengal per the Eighth Schedule of the Indian Constitution. It is spoken by around 7.6 million people in India, Bangladesh, Bhutan and Nepal, making it the third most-spoken Austroasiatic language after Vietnamese and Khmer.

Santali is characterized by a split into at least a northern and southern dialect sphere, with slightly different sets of phonemes: Southern Santali has six phonemic vowels, in contrast with eight or nine in Northern Santali, different lexical items, and to a certain degree, variable morphology. Santali is recognized by linguists as being phonologically conservative within the Munda branch. Unlike many Munda languages that had their vowel systems restructured and shrunk to five such as Mundari, Ho, and Kharia, Santali retains a larger vowel system of eight phonemic cardinal vowels, which is very unusual in the South Asian linguistic area. The language also uses vowel harmony processes in morphology and expressives similar to Ho and Mundari. Morphosyntactically, Santali, together with Sora, are considered less restructured than other Munda languages, having less influence from Indo-Aryan and Dravidian languages. Clause structure is topic-prominent by default.

The Insurgency in Northeast India is ongoing armed conflicts in a number of India's northeastern states between several militants groups with various political ideologies, including separatism and Christian nationalism, and the Indian government.

Northeast India consists of eight states: the seven sister states of Assam, Meghalaya, Tripura, Arunachal Pradesh, Mizoram, Manipur, and Nagaland, and the brother state Sikkim included later. These states are connected to the rest of India by the Siliguri Corridor, a strip of land as narrow as 14.29 miles (23.00 km) wide. Tensions have existed between insurgents in the seven sister states and the central government as well as amongst their native indigenous people and migrants from other parts of India and illegal immigrants for many decades now.

Sale and consumption of alcoholic liquor for human consumption is prohibited in the states of Bihar,Gujarat, Mizoram, and Nagaland. All other Indian states and union territories permit the sale and consumption of alcohol.

The directive principles of state policy (DPSP) in the constitution of India (article 47) state that "....the State shall endeavor to bring about prohibition of the consumption except for medicinal purposes of intoxicating drinks and of drugs which are injurious to health". The Directive Principles are not-justiciable rights of the people but fundamental in the governance of the country. It shall be the duty of the State to apply these principles in making policy laws per Article 47. Per Article 38, state and union governments, as duty, shall make further detailed policies and laws for implementation considering DPSPs as fundamental policy.

Mizo chieftainship refers to the system of chieftainship used by the Mizo people, which historically operated as a gerontocracy. The chieftain system persisted among the various clans and tribes from the precolonial era through to the British colonial period and Indian independence briefly. The Mizo Union advocated for abolishing chieftainship in Mizoram. The chieftainships of Mizoram were eventually disbanded with the Assam-Lushai District ("Acquisition of Chief's Rights") Act in 1954.
