The Mughal Empire was an early modern empire in South Asia. At its peak, the empire stretched from the outer fringes of the Indus River Basin in the west, northern Afghanistan in the northwest, and Kashmir in the north, to the highlands of present-day Assam and Bangladesh in the east, and the uplands of the Deccan Plateau in South India.

The Mughal Empire is conventionally said to have been founded in 1526 by Babur, a ruler from what is today Uzbekistan, who employed aid from the neighboring Safavid and Ottoman Empires to defeat the sultan of Delhi, Ibrahim Lodi, in the First Battle of Panipat and to sweep down the plains of North India. The Mughal imperial structure, however, is sometimes dated to 1600, to the rule of Babur's grandson, Akbar. This imperial structure lasted until 1720, shortly after the death of the last major emperor, Aurangzeb, during whose reign the empire also achieved its maximum geographical extent. Reduced subsequently to the region in and around Old Delhi by 1760, the empire was formally dissolved by the British Raj after the Indian Rebellion of 1857.

Bengali, also known by its endonym Bangla, is a classical Indo-Aryan language belonging to the Indo-Iranian branch of the Indo-European language family. It is primarily spoken by the Bengali people, native to the Bengal region (Bangladesh, India's West Bengal and parts of Southern Assam) as well as Tripura of South Asia. With over 242 million (24.2 crore) native speakers and another 43 million (4.3 crore) as second language speakers as of 2025, Bengali is the sixth most spoken native language and the seventh most spoken language by the total number of speakers in the world.

Bengali is the official, national, and most widely spoken language of Bangladesh, with 98% of Bangladeshis using Bengali as their first language. It is the second-most widely spoken language in India. It is the official language of the Indian states of West Bengal, Tripura and the Barak Valley region of the state of Assam. It is also the second official language of the Indian state of Jharkhand since September 2011. It is the most widely spoken language in the Andaman and Nicobar Islands in the Bay of Bengal, and is spoken by significant populations in other states including Bihar, Arunachal Pradesh, Delhi, Chhattisgarh, Meghalaya, Mizoram, Nagaland, Odisha and Uttarakhand. Bengali is also spoken by the Bengali diasporas (Bangladeshi diaspora and Indian Bengalis) across Europe, North America, the Middle East and other regions.

The University of Dhaka (Bengali: ঢাকা বিশ্ববিদ্যালয়), also known as Dhaka University (DU), is a public research university located in Dhaka, Bangladesh. Established in 1921, it is the oldest active university in the country.

The University of Dhaka was founded in 1921 under the Dacca University Act 1920 of the Indian Legislative Council. The establishment of the university in Dhaka was initiated with 600 acres of land requisitioned by the British government in 1905 after a new province of East Bengal and Assam was formed with Dhaka as its capital. Part of the land requisitioned belonged to the estate of Nawab Bahadur Sir Khwaja Salimullah. It is modeled after British universities. Currently it is the largest public research university in Bangladesh, with a student body of 46,150 and a faculty of 1,992.

Hickory is a common name for trees composing the genus Carya, which includes 19 species accepted by Plants of the World Online.

Seven species are native to southeast Asia in China, Indochina, and northeastern India (Assam), and twelve are native to North America. A number of hickory species are used for their edible nuts or for their wood.

Samudragupta (Gupta script: Sa-mu-dra-gu-pta; 318–375) was the second emperor of the Gupta Empire of ancient India. As a son of the Gupta emperor Chandragupta I and the Licchavi princess Kumaradevi, he inherited the kingdom and transformed it into a vast empire through his military campaigns. His reign was marked by political expansion, administrative efficiency, and cultural patronage, particularly of Sanskrit literature and Vaishnavite Hindu rituals. Samudragupta’s legacy as a warrior, administrator, and benefactor of scholars contributed to the golden age of India.

The Allahabad Pillar inscription, a prashasti (eulogy) composed by his courtier Harisena, credits him with extensive military conquests. It suggests that he defeated several kings of northern India, and annexed their territories into his empire. He also marched along the south-eastern coast of India, advancing as far south as Kanchipuram in the Pallava kingdom. In addition, he subjugated several frontier kingdoms and tribal oligarchies. At the height of his power, his empire under his direct control extended from Ravi River in the west (present-day Punjab) to the Brahmaputra River in the east (present-day Assam), and from the Himalayan foothills in the north to central India in the south-west; several rulers along the south-eastern coast were also his tributaries. The inscription also states that many neighbouring rulers tried to please him, which probably refers to his friendly relations with them.

The Yarlung Tsangpo, also called Yarlung Zangbo (Tibetan: ཡར་ཀླུངས་གཙང་པོ་, Wylie: yar kLungs gTsang po, ZWPY: Yarlung Zangbo) and Yalu Zangbu River (Chinese: 雅鲁藏布江; pinyin: Yǎlǔzàngbù Jiāng) is a river that flows through the Tibet Autonomous Region of China and Arunachal Pradesh of India. It is the longest river of Tibet and the fifth longest in China. The upper section is also called Dangque Zangbu meaning "Horse River".

Originating from the Angsi Glacier in western Tibet, southeast of Mount Kailash and Lake Manasarovar, it later forms the South Tibet Valley and Yarlung Tsangpo Grand Canyon before passing into the state of Arunachal Pradesh in India. Downstream from Arunachal Pradesh, the river becomes far wider and is called the Siang. After reaching Assam, the river is known as the Brahmaputra.

The Brahmaputra is a trans-boundary river which flows through Southwestern China, Northeastern India, and Bangladesh. It is known as the Brahmaputra or Luit in Assamese, Yarlung Tsangpo in Tibetan, the Siang/Dihang River in Arunachali, and Jamuna River in East Bengal. By itself, it is the 9th largest river in the world by discharge, and the 15th longest.

It originates in the Manasarovar Lake region, near Mount Kailash, on the northern side of the Himalayas in Burang County of Tibet where it is known as the Yarlung Tsangpo River. The Brahmaputra flows along southern Tibet to break through the Himalayas in great gorges (including the Yarlung Tsangpo Grand Canyon) and into Arunachal Pradesh. It enters India near the village of Gelling in Arunachal Pradesh and flows southwest through the Assam Valley as the Brahmaputra and south through Bangladesh as the Jamuna (not to be confused with the Yamuna of India). In the vast Ganges Delta, it merges with the Ganges, popularly known as the Padma in Bangladesh, and becomes the Meghna and ultimately empties into the Bay of Bengal.

Bengal (/bɛnˈɡɔːl/ ben-GAWL) is a geographical, ethnolinguistic, historically geopolitical region in South Asia, located north of the Bay of Bengal. Today, it is politically divided between the sovereign state of Bangladesh, the Indian state of West Bengal, and Karimganj district in the Indian state of Assam.

The ancient Vanga Kingdom is widely regarded as the namesake of the Bengal region. The Bengali calendar dates back to the reign of Shashanka in the 7th century CE. The Pala Empire was founded in Bengal during the 8th century. The Sena dynasty and Deva dynasty ruled between the 11th and 13th centuries. By the 14th century, Bengal was absorbed by Muslim conquests in the Indian subcontinent. An independent Bengal Sultanate was formed and became the eastern frontier of the Islamic world. During this period, Bengal's rule and influence spread to Assam, Arakan, Tripura, Bihar, and Odisha (formerly- Orissa). Bengal Subah later emerged as a prosperous part of the Mughal Empire.

West Bengal is a state in the eastern portion of India. It is situated along the Bay of Bengal. It had a population of over 91 million inhabitants within an area of 88,752 km (34,267 sq mi) as of 2011. The population estimate as of 2023 is 99,723,000. West Bengal is the fourth-most populous and thirteenth-largest state by area in India, as well as the eighth-most populous country subdivision of the world. As a part of the Bengal region of the Indian subcontinent, it borders Bangladesh in the east, and Nepal and Bhutan in the north. It also borders the Indian states of Jharkhand, Odisha, Bihar, Sikkim and Assam. The state capital is Kolkata, the third-largest metropolis, and seventh largest city by population in India. West Bengal includes the Darjeeling Himalayan hill region, the Ganges delta, the Rarh region, the coastal Sundarbans and the Bay of Bengal. The state's main ethnic group are the Bengalis, with the Bengali Hindus forming the demographic majority.

The area's early history featured a succession of Indian empires, internal squabbling, and a tussle between Hinduism and Buddhism for dominance. Ancient Bengal was the site of several major Janapadas, while the earliest cities date back to the Vedic period. The region was part of several ancient pan−Indian empires, including the Vangas, Mauryans, and the Guptas. The citadel of Gauḍa served as the capital of the Gauda kingdom, the Pala Empire, and the Sena Empire. Islam was introduced through trade with the Abbasid Caliphate, but following the Ghurid conquests led by Bakhtiyar Khalji and the establishment of the Delhi Sultanate, the Muslim faith spread across the entire Bengal region. During the Bengal Sultanate, the territory was a major trading nation in the world, and was often referred by the Europeans as the "richest country to trade with". It was absorbed into the Mughal Empire in 1576. Simultaneously, some parts of the region were ruled by several Hindu states, and Baro-Bhuyan landlords, and part of it was briefly overrun by the Suri Empire. Following the death of Emperor Aurangzeb in the early 1700s, the proto-industrialised Mughal Bengal became a semi-independent state under the Nawabs of Bengal, and showed signs of the first Industrial Revolution. The region was later annexed into the Bengal Presidency by the British East India Company after the Battle of Buxar in 1764. From 1772 to 1911, Calcutta was the capital of all of East India Company's territories and then the capital of the entirety of India after the establishment of the Viceroyalty. From 1912 to India's Independence in 1947, it was the capital of the Bengal Province.

The Bengal Sultanate (Middle Bengali: শাহী বাঙ্গালাহ্, Classical Persian: سلطنت بنگاله) was a late medieval sultanate based in the Bengal region in eastern South Asia between the 14th and 16th century. It was the dominant power of the Ganges-Brahmaputra Delta, with a network of mint towns spread across the region. The Bengal Sultanate had a circle of vassal states in the Indian subcontinent and Southeast Asia, including parts of Odisha in the southwest, parts of Bihar in the northwest, parts of Assam in the northeast, Arakan in the southeast, and Tripura in the east.

The Bengal Sultanate controlled large parts of eastern South Asia during its five dynastic periods, reaching its peak under Jalaluddin Muhammad Shah. Its raids and conquests reached Nepal in the north, Brahmaputra Valley (modern-day Assam) in the east, and Jaunpur and Varanasi in the west. It was reputed as a thriving trading nation. Its decline began with an interregnum by the Sur Empire, followed by Mughal conquest and disintegration into petty kingdoms. The Bengal Sultanate was a Sunni Muslim monarchy with Bengali, Turco-Persian, Afghan and Abyssinian elites. The most prominent dynasties were the Ilyas Shahi, House of Ganesha and Hussain Shahi. The kingdom was known for its religious pluralism where non-Muslim communities co-existed peacefully. While Persian was used as the primary official, diplomatic and commercial language, it was under the Sultans that Bengali first received court recognition as an official language. The cities of the Bengal Sultanate are termed as Mint Towns where the historical taka was minted. These cities were adorned with stately medieval buildings. In 1500, the royal capital of Gaur was the fifth-most populous city in the world. Other notable cities included the initial royal capital of Pandua, the economic hub of Sonargaon, the Mosque City of Bagerhat, and the seaport and trading hub of Chittagong. The Bengal Sultanate was connected to states in Asia, Africa, the Indian Ocean, and Europe through maritime links and overland trade routes. The Bengal Sultanate was a major trading center on the coast of the Bay of Bengal. It attracted immigrants and traders from different parts of the world. Bengali ships and merchants traded across the region, including in Malacca, China, and the Maldives.

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.

The Tamang people (རྟ་དམག་; Devanagari: तामाङ; tāmāṅ) are an ethnic group living in Nepal, Northeast India and southern Bhutan. In Nepal, they are concentrated in the central hilly and Himalayan regions and constituted over 1.6 million people in the 2021 census. In India, Tamang people live in the state of Sikkim, in the Darjeeling and Kalimpong districts of West Bengal and in Assam. In Bhutan, they live foremost in the southern foothills including Tsirang District, Dagana District, Samtse District, Chukha District, Sarpang District and Samdrup Jongkhar District. The Tamang language is the fifth most-spoken language in Nepal.

The Mughal Empire was an early modern empire that ruled most of the Indian subcontinent. At its peak, the empire stretched from the outer fringes of the Indus River Basin in the west, northern Afghanistan in the northwest, and Kashmir in the north, to the highlands of present-day Assam and Bangladesh in the east, and the uplands of the Deccan Plateau in South India.

The Mughal Empire is conventionally said to have been founded in 1526 by Babur, a ruler from what is now Uzbekistan, who with the help of the neighbouring Safavid and Ottoman Empires defeated the sultan of Delhi, Ibrahim Lodi, in the First Battle of Panipat and swept down the plains of North India. The Mughal imperial structure, however, is sometimes dated to 1600, to the rule of Babur's grandson, Akbar. This imperial structure lasted until 1720, shortly after the death of the last major emperor, Aurangzeb, during whose reign the empire also achieved its maximum geographical extent. Reduced subsequently to the region in and around Old Delhi by 1760, the empire was formally dissolved by the British Raj after the Indian Rebellion of 1857.

The 1950 Assam–Tibet earthquake, also known as the Assam earthquake, occurred on 15 August and had a moment magnitude of 8.7. The epicentre was located in the Mishmi Hills. It is one of the strongest earthquakes ever recorded on land.

Occurring on a Tuesday at 7:39 PM Indian Standard Time, the earthquake was destructive in both Assam (India) and Tibet (China), and approximately 4,800 people were killed. The earthquake is notable as being the largest recorded quake caused by continental collision rather than subduction, and is also notable for the loud noises produced by the quake and reported throughout the region.

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.
