Odisha in the context of Bahaghara

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.

The Kalinga war (ended c. 261 BCE) was fought in ancient India between the Mauryan Empire under Ashoka the Great and Kalinga, an independent feudal kingdom located on the east coast, in the present-day state of Odisha and northern parts of Andhra Pradesh. It is presumed that the battle was fought on Dhauli hills in Dhauli which is situated on the banks of Daya River. The Kalinga War was one of the largest and deadliest battles in Indian history.

This is the only major war Ashoka fought after his accession to the throne, and marked the close of the empire-building and military conquests of ancient India that began with the Mauryan Emperor Chandragupta Maurya. The war cost nearly 250,000 lives.

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.

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.

Jharkhand (Hindi: Jhārkhaṇḍ, pronounced [d͡ʒʱaːɾkʰəɳɖ] ; lit. 'the land of forest ') is a landlocked state in eastern India. The state shares borders with the states of West Bengal to the east, Chhattisgarh to the west, Uttar Pradesh to the northwest, Bihar to the north and Odisha to the south. It is the 15th largest state by area, and the 14th largest by population. Hindi is the official language of the state. The city of Ranchi is its capital, and Dumka its sub-capital. The state is known for its waterfalls, hills and holy places; Baidyanath Dham, Parasnath, Dewri and Rajrappa are major religious sites. Jharkhand is primarily rural, with about 24% of its population living in cities as of 2011.

Jharkhand suffers from what is sometimes termed a resource curse: it accounts for more than 40% of India's mineral production but 39.1% of its population is below the poverty line and 19.6% of children under five years of age are malnourished.

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 Nawabs of Bengal were the Independent hereditary rulers of Bengal. In the early 18th-century, the Nawab of Bengal was the independent ruler of Bengal (Bengal, Bihar and Orissa which constitute the modern-day Indian states of West Bengal, Bihar and Odisha and the sovereign country of Bangladesh). The Bengal Subah reached its peak during the reign of Nawab Shuja-ud-Din Muhammad Khan. They are often referred to as the Nawab of Bengal, Bihar and Orissa (Bengali: বাংলা, বিহার ও উড়িষ্যার নবাব). The Nawabi Bengal's capital were based in Murshidabad which was centrally located within Bengal, Bihar, and Odisha. Their chief, a former prime minister, became the first Nawab. The Nawabs governed as independent monarchs. The Nawabs, backed by bankers such as the Jagat Seth, became the financial backbone of the Subcontinent court.

The Nawabs, especially under the rule of Alivardi Khan of 16 years, were heavily engaged in various wars against the Marathas. Towards the end, he turned his attention to rebuilding and restoring Bengal.

Kalinga is a historical region of India. It is generally defined as the eastern coastal region between the Ganges and the Godavari rivers, although its boundaries have fluctuated with the territory of its rulers. The core territory of Kalinga now encompasses all of Odisha and some part of northern Andhra Pradesh. At its widest extent, the Kalinga region also included parts of present-day Chhattisgarh, extending up to Amarkantak in the west. In the ancient period it extended until the bank of the Ganges river.

The Kalingas have been mentioned as a major tribe in the legendary text Mahabharata. In the 3rd century BCE, the region came under Mauryan control as a result of the Kalinga War. It was subsequently ruled by several regional dynasties whose rulers bore the title Kalingādhipati ("Lord of Kalinga"); these dynasties included Mahameghavahana, Vasishtha, Mathara, Pitrbhakta, Shailodbhava, Bhaumkara, Somavamshi, and Eastern Ganga. The medieval era rulers to rule over the Kalinga region were the Suryavamsa Gajapatis, Bhoi dynasty, Paralakhemundi Gangas and the zamindaris of Ganjam and Vizagapatam.

The Vijayanagara Empire, also known as the Karnata Kingdom, was a late medieval Hindu empire that ruled much of southern India. It was established in 1336 by the brothers Harihara I and Bukka Raya I of the Sangama dynasty, belonging to the Yadava clan of Chandravamsa lineage.

The empire rose to prominence as a culmination of attempts by the southern powers to ward off Muslim invasions by the end of the 13th century. At its peak in the early 16th century under Krishnadevaraya, it subjugated almost all of Southern India's ruling dynasties and pushed the Deccan sultanates beyond the Tungabhadra-Krishna River doab region, in addition to annexing the Gajapati Empire (Odisha) up to the Krishna River, becoming one of the most prominent states in India. The empire's territory covered most of the lands of the modern-day Indian states of Karnataka, Andhra Pradesh, Tamil Nadu, Goa, and some parts of Telangana, Maharashtra and Kerala.

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.

Parboiled rice, also called converted rice, easy-cook rice, sella rice, and miniket (as predominantly called in West Bengal and Odisha in India, and in Bangladesh) is rice that has been partially boiled in the husk. The three basic steps of parboiling are soaking, steaming and drying. These steps make the rice easier to process by hand, while also boosting its nutritional profile, changing its texture, and making it more resistant to weevils. The treatment is practiced in many parts of the world.

Parboiling drives nutrients, especially thiamine, from the bran to the endosperm, hence parboiled white rice is mostly nutritionally similar to brown rice. Given the pale tan color that results from these bran components, parboiled rice is sometimes called saffron sella.

Dandakaranya (Sanskrit: दण्डकारण्य, romanized: Daṇḍakāraṇya), also rendered Dandaka (Sanskrit: दंडक, IAST: Daṃḍaka), is a historical region and the name of a forest mentioned in the ancient Indian epic Ramayana. It covers about 92,200 square kilometres (35,600 sq mi) of land, which includes the Abujhmar Hills in the west and borders the Eastern Ghats in the east, including regions of Andhra Pradesh, Chhattisgarh, Odisha, and Telangana states. It spans about 300 kilometres (200 mi) from north to south and about 500 kilometres (300 mi) from east to west.

Panchayatana puja (IAST Pañcāyatana pūjā) also known as Pancha Devi Deva Puja is a system of puja (worship) in the Smarta sampradaya, which is one of four major sampradayas of Hinduism. It consists of the worship of five deities set in a quincunx pattern, the five deities being Ganesha, Mahadevi, Shiva, Vishnu and Surya. Sometimes an Ishta Devata (any personal god of devotee's preference) or Indra or Kartikeya is the sixth deity in the mandala (see Shanmata).

Panchayatana puja has been attributed to Adi Shankara, the 8th century CE Hindu philosopher. It is a practice that became popular in medieval India. However, archaeological evidence suggests that this practice long predates the birth of Adi Shankara. Many Panchayatana mandalas and temples have been uncovered that are from the Gupta Empire period, and one Panchayatana set from the village of Nand (about 24 kilometers from Ajmer) has been dated to belong to the Kushan Empire era (pre-300 CE). The Kushan period set includes Shiva, Vishnu, Surya, Shakti and one deity whose identity is unclear. According to James Harle, major Hindu temples from 1st millennium CE embed the pancayatana architecture very commonly, from Odisha to Karnataka to Kashmir; and the temples containing fusion deities such as Harihara (half Shiva, half Vishnu) are set in Panchayatana worship style.

Shakala Shaka (Sanskrit: शाकल शाखा; IAST: Śākala Śākhā), is the oldest shakha (from skt. śākhā f. "branch" or "recension") of the Rigveda. The Śākala tradition is mainly followed in Maharashtra, Karnataka, Kerala, Odisha, Tamil Nadu and Uttar Pradesh. The Mahābhāṣya of Patañjali refers to 21 śākhās of the Rigveda; however, according to Śaunaka's Caraṇa-vyuha there are five śākhās for the Rigveda: the Śākala, Bāṣkala, Aśvalayana, Śaṅkhāyana, and Māṇḍukāyana, of which only the Śākala and Bāṣkala and few of the Aśvalayana are now extant. The only complete recension of Rigveda known today is of the Śākala School. There is a claim that Śaṅkhāyana Śākhā is still known to a few Vedapathis in Uttar Pradesh and Gujarat but this is not certain.

The main saṃhitā for Śākala Sākhā is the Śākala Saṃhitā and the corresponding brahmana is Aitareya Brāhmaṇa. The main Upaniṣat of the Śākala Śākhā is Aitareya Upaniṣat. The Śrauta Sūtram for Śākala Shākhā is Āśvalāyaṇa Śrauta Sūtra and the Gṛhya Sutra is Āśvalāyana Gṛhya Sūtram. The Āraṇyaka of Śākala Śākhā is Aitareya Āraṇyaka.
