Jharkhand in the context of "Eastern India"

The Bengal Subah (Bengali: সুবাহ বাংলা, Persian: صوبه بنگاله), also referred to as Mughal Bengal and Bengal State (after 1717), was the largest subdivision of the Mughal Empire encompassing much of the Bengal region, which includes modern-day Bangladesh, the Indian state of West Bengal, and some parts of the present-day Indian states of Bihar (from 1733), Jharkhand and Odisha between the 16th and 18th centuries. The province was established following the dissolution of the Bengal Sultanate, a major trading nation in the world, when the region was absorbed into the Mughal Empire. Bengal was the wealthiest region in the Indian subcontinent.

Aurangzeb (r. 1658–1707) described Bengal Subah as 'the paradise of Nations' and the "Golden Age of Bengal". It alone accounted for 40% of Dutch imports from Asia. The eastern part of Bengal was globally prominent in industries such as textile manufacturing and shipbuilding, and it was a major exporter of silk and cotton textiles, steel, saltpeter, and agricultural and industrial produce in the world. The region was also the basis of the Anglo-Bengal War.

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.

Bihar (pronounced [bɪˈɦaːr] ), also spelled Behar in colonial documents, is a state in Eastern India. It is the second largest state by population, the 12th largest by area, and the 14th largest by GDP in 2024. Bihar borders Uttar Pradesh to its west, Nepal to the north, the northern part of West Bengal to the east, and Jharkhand to the south. Bihar is split by the river Ganges, which flows from west to east. On 15 November 2000, a large chunk of southern Bihar was ceded to form the new state of Jharkhand. Around 11.27% of Bihar's population live in urban areas as per a 2020 report. Additionally, almost 58% of Biharis are below the age of 25, giving Bihar the highest proportion of young people of any Indian state. The official language is Hindi, which shares official status alongside that of Urdu. The main native languages are Maithili, Magahi and Bhojpuri, but there are several other languages being spoken at smaller levels.

In Ancient and Classical India, the area that is now Bihar was considered the centre of political and cultural power and as a haven of learning. Parshvanatha, the 23rd Tirthankar led the shramana order in this region in 9th century BCE. Jainism was revived and re-organised by Mahavira, the 24th Tirthankar in 6th century BCE. From Magadha arose India's first empire, the Maurya empire, as well as one of the world's most widely adhered-to religions: Buddhism. Magadha empires, notably under the Maurya and Gupta dynasties, unified large parts of South Asia under a central rule. Another region of Bihar, Mithila, was an early centre of learning and the centre of the Videha kingdom.

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.

Uttar Pradesh (UTT-ər prə-DESH, abbr. UP; Hindi: Uttar Pradēś, pronounced [ˈʊtːəɾ pɾəˈdeːʃ] , lit. 'Northern Province') is a state in northern India. With over 241 million inhabitants, it is the most populated state in India as well as the most populous country subdivision in the world – more populous than all but four other countries outside of India (China, United States, Indonesia, and Pakistan) – and accounting for 16.5 per cent of the population of India or around 3 per cent of the total world population. The state is bordered by Rajasthan to the west, Haryana, Himachal Pradesh and Delhi to the northwest, Uttarakhand and Nepal to the north, Bihar to the east, Madhya Pradesh, Chhattisgarh and Jharkhand to the south.

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.

Odisha (Odia: oṛiśā, pronounced [oˈɽisa] ) is a state located in Eastern India. It is the eighth-largest state by area, and the eleventh-largest by population, with over 41 million inhabitants. The state also has the third-largest population of Scheduled Tribes in India. It neighbours the states of Jharkhand and West Bengal to the north, Chhattisgarh to the west, and Andhra Pradesh to the south. Odisha has a coastline of 485 kilometres (301 mi) along the Bay of Bengal in the Indian Ocean. The region is also known as Utkaḷa and is mentioned by this name in India's national anthem, Jana Gana Mana.

The ancient kingdom of Kalinga, which was invaded by the Mauryan Emperor Ashoka in 261 BCE resulting in the Kalinga War, coincides with the borders of modern-day Odisha. The modern boundaries of Odisha were demarcated by the British Indian government, the Orissa Province was established on 1 April 1936, consisting of the Odia-speaking districts of Bihar and Orissa Province, Madras Presidency and Central Provinces. Utkala Divas (lit. 'Odisha Day') is celebrated on 1 April. Cuttack was made the capital of the region by Anantavarman Chodaganga in c. 1135, after which the city was used as the capital by many rulers, through the British era until 1948. Thereafter, Bhubaneswar became the capital of Odisha.

Chhattisgarh (/ˈtʃætɪsɡɑːr/; Hindi: [ˈtʃʰət̪ːiːsgəɽʱ]) is a landlocked state in Central India. It is the ninth largest state by area, and with a population of roughly 30 million, the seventeenth most populous. It borders seven states – Uttar Pradesh to the north, Madhya Pradesh to the northwest, Maharashtra to the southwest, Jharkhand to the northeast, Odisha to the east, Andhra Pradesh and Telangana to the south. Formerly a part of Madhya Pradesh, it was granted statehood on 1 November 2000 with Raipur as the designated state capital.

The Sitabenga caves in Chhattisgarh, one of the earliest examples of theatre architecture in India, are dated to the Mauryan period of 3rd century BCE.The region was split between rivaling dynasties from the sixth to twelfth centuries, and parts of it were briefly under the Chola dynasty in the 11th century. Eventually, most of Chhattisgarh was consolidated under the Kingdom of Haihaiyavansi, whose rule lasted for 700 years until they were brought under Maratha suzerainty in 1740. The Bhonsles of Nagpur incorporated Chhattisgarh into the Kingdom of Nagpur in 1758 and ruled until 1845, when the region was annexed by the East India Company, and was later administered under the Raj until 1947 as the Chhattisgarh Division of the Central Provinces. Some areas constituting present-day Chhattisgarh were princely states that were later merged into Madhya Pradesh. The States Reorganisation Act, 1956 placed Chhattisgarh in Madhya Pradesh, and it remained a part of that state for 44 years.
