East India is a region of India consisting of the Indian states of Bihar, Jharkhand, Odisha and West Bengal and also the union territory of the Andaman and Nicobar Islands.
The states of Bihar and West Bengal lie on the Indo-Gangetic plain. Jharkhand is situated on the Chota Nagpur Plateau. Odisha lies on the Eastern Ghats and the Deccan Plateau. West Bengal's capital Kolkata is the largest city of this region. The Kolkata Metropolitan Area is the country's third largest metropolitan region. The region is bounded by Bhutan, Nepal and the state of Sikkim in the north, the states of Uttar Pradesh and Chhattisgarh on the west, the state of Andhra Pradesh in the south and the country of Bangladesh in the east. It is also bounded by the Bay of Bengal in the south-east. It is connected to the Seven Sister States of Northeast India by the narrow Siliguri Corridor in the north east of West Bengal.

## History

During the Neolithic period, agriculture started in South Asia. Neolithic settlements have been found in Chirand. In the Kabra-Kala mound at the confluence of the Son and North Koel rivers in Palamu district, various antiquities and art objects from the Neolithic to medieval periods have been found; the pot-sherds of redware, black and red ware, black ware, black slipped ware, and NBP ware are from the Chalcolithic to late medieval periods. There are ancient cave paintings in Isko, Hazaribagh district, from the Meso-chalcolithic period (9,000–5,000 BCE). From Kuchai, near Baripada, various Neolithic tools like hoes, chisels, pounders, mace heads, grinding stones and also pieces of pottery. Prehistoric paintings and inscriptions have also been found in Garjan Dongar in Sundergarh district, and Ushakothi in Sambalpur district and Vimkramkhol in Jharsuguda district. There has been an uncertainty about the inscriptions at Ushakothi and Vimkramkhol regarding whether they are in a proto-Brahmi script. Yogimath near Khariar has cave paintings from the Neolithic. There is Chalcolithic sites in Pandu Rajar Dhibi in the lower Ajay valley in West Bengal. Dihar is an archaeological site of Neolithic and Early village farming culture located in the Bankura district of West Bengal. Construction of the settlement in Dihar is believed to have started around 2700 BC. Evidence of 42,000 years old human habitation has been found at the foothills of the Ajodhya Hills in West Bengal. Iron slag, microliths, and potsherds from 1400 BCE, according to carbon dating, were discovered in Singhbhum district. During the late Vedic period, several janapadas emerged in India. In the 6th century BCE, the mahajanapadas emerged in several parts of the Indian subcontinent.
The region was the historical centre of the Nanda, Maurya, Shunga, Gupta and Pala empires that ruled much of the Indian sub-continent at their prime. In medieval India, it was incorporated into the Mughal, Maratha and then the British empire. After independence in 1947, the states joined the Indian Union and took their current form after the States Reorganisation Act of 1956. Today, they continue to face problems of overpopulation, environmental degradation and pervasive corruption despite significant economic and social progress.
After the Kalinga War the Maurya king Ashoka sent emissaries to spread Buddhism across Asia. The university of Nalanda was in Bihar. Chinese travellers visited Buddhist and Hindu temples and libraries in the universities of Magadha Empire. The Emperor of Kalinga Mahameghavahana Aira Kharavela was one of the most powerful monarchs of ancient India. The Jain thirkhankar Mahaveer was born here and founded Jainism.
Islamic invasions in the 13th century resulted in the collapse of Hindu kings and most Buddhists, especially in East Bengal, converted to Islam. East India including Bihar and West Bengal was part of the Mughal Empire in the 16th and 17th centuries. Odisha remained the only powerful Hindu dynastic stronghold under the rule of Soma/Keshari Dynasty, Bhanja Dynasty, Eastern Ganga Dynasty, Suryavanshi Dynasty and Bhoi(Khordha) dynasty till the end of the 16th century. The mighty Nalanda University existed at Nalanda which was destroyed by Bakhtiar Khilji during the 12th century and also defeated Sena Dynasty. Sher Shah Suri, who became king of India after defeating Humayun, founded the city of Patna on the ruins of ancient Pataliputra.
Islam arrived during the 7th century CE and became dominant gradually since the early 13th century with the advent of Muslim rulers as well as Sunni missionaries such as Shah Jalal in the region. Later, Muslim rulers, starting from the Delhi Sultanate initiated the preaching of Islam by building mosques. From the 14th century onward, it was ruled by the Bengal Sultanate, founded by king Shamsuddin Ilyas Shah, beginning a period of the country's economic prosperity and military dominance over the regional empires, which was referred by the Europeans to as the richest country to trade with. Afterwards, the entire East India came under the Mughal Empire, becoming as the most advanced parts in the world. Bengal Subah generated almost half of the empire's GDP and 12% of the world's GDP, larger than the entirety of western Europe.
With the arrival of the Europeans in the 17th century, outposts were established in Odisha Coast and Bengal. The European traders established their trade centres in the ports of Balasore, Pipili, Palur in the Odisha Coast during the rule of the last independent Hindu king Gajapati Prataprudra Dev. The Portuguese were in Chittagong, Dutch in Chinsura, French in Pondicherry and the English founded Calcutta. The Maratha Invasion of Bengal badly affected the economy of Bengal and it is estimated that 400,000 people were butchered by the Hindu Maratha bargis and many women and children gang raped, and the genocide has been considered to be among the deadliest massacres in Indian history. In 1756, the British East India Company defeated the local Indian Muslim rulers in Plassey and established British Rule in the subcontinent. Its capital Calcutta grew into one of the world's greatest ports. Tea from Calcutta was off-loaded by American separatists in the American War of Independence in the 1770s. In the 19th century, Calcutta's traders and merchants traded with the rest of the British Empire, continental Europe, the United States and China. Indentured Indian labourers from Bihar, sailed to new homes in Fiji, Mauritius, Guyana, Surinam and South Africa.
India's independence movement had strong roots in East India. The feudal land system, established through the Permanent Settlement of Bengal, was unpopular among the peasant cultivators and the numerous agricultural labourers found all over Bihar and Bengal (Khetmazdoors). The Indian Rebellion of 1857 started in Bengal. Eventually the British prevailed, and Calcutta remained capital of Britain's Asian dominions until 1911. During Gandhi's independence movement, the Bihari village of Champaran was an important supporter of non-violent resistance. Great poets of the stature of Rabindranath Tagore championed the movement for self-rule.
The Partition also had its roots in undivided Eastern India. The Muslim League was founded in Dhaka in 1906. In the 1937 provincial elections, it came to power in Bengal in alliance with the Krishak Praja Party. in 1944, it gained an absolute majority in the Bengal Assembly, and Hussein Suhrawardy became the Chief Minister. After widespread communal violence during the Direct Action Day protests in Calcutta, leading to further communal violence across British India, the creation of Pakistan became inevitable. In 1947, further communal violence displaced millions as independence and partition of British India occurred. Some Bihari and Bengali Muslims fled to the newly created East Pakistan. Most East Bengal Hindus fled to India.
The 1950s saw industrial progress in East India. These were cut short with the conflict in neighbouring East Pakistan and by the Communist movement at home. In 1971, in the course of Bangladesh's independence struggle, millions of refugees poured into East India. Bihar and Odisha struggled with economic issues during the British rule and in the beginning of post independent India due to rising naxalism frequent natutal calamities such as flood and cyclone. But in recent years, the state of Odisha have shown impressive growth record and developed steadily. The economic boom since 2005 started to spread new malls, highways, airports and IT office complexes, but not evenly across the region. Jharkhand became a separate state on 15 November 2000 from Bihar. In the modern times, these states have seen rapid transformation and home to several mineral and metal based industries, coal based thermal powers units, oil refineries, ports, textile industries and well established public and private educational institutes. West Bengal, Bihar, Odisha and Jharkhand rank 6th, 16th, 14th and 18th in the List of Indian states by GDP. Odisha has shown consistent growth in the state GDP and received the recognition of the fastest-growing economy among the states in India.

## Culture
### Cuisine

Bengali food has inherited a large number of influences, both foreign and pan-Indian, arising from a historical and strong trade links with many parts of the world.

Odisha
Odia cuisine refers to the cooking of the eastern Indian state of Odisha. Foods from this area are rich and varied, while relying heavily on local ingredients. The flavours are usually subtle and delicately spiced, quite unlike the fiery curries typically associated with Indian cuisine. Fish and other seafood such as crab and shrimp are popular. Chicken and mutton are also consumed, but somewhat occasionally. Only 6% of the population of Odisha is vegetarian, and this is reflected in its cuisine. The oil base used is mostly mustard oil, but in festivals ghee is used. Panch phutana, a mix of cumin, mustard, fennel, fenugreek and kalonji (nigella) is widely used for tempering vegetables and dals, while garam masala (curry powder) and haladi (turmeric) are commonly used for non-vegetarian curries. Pakhala, a dish made of rice, water, and yogurt, that is fermented overnight, is very popular in summer, particularly in the rural areas. Oriyas are very fond of sweets and no Oriya repast is considered complete without some dessert at the end. Festivals and fasts witness a cuisine without onion and garlic, whereas other days witness an aroma of garlic and onion paste in curries. One can find restaurants serving food without onion and garlic in major places like Puri and other coastal area, which is run by Brahmin owners.
Odisha has a culinary tradition spanning centuries if not millennia. The kitchen of the Jagannath temple in Puri is reputed to be the largest in the world, with a thousand cooks, working around 752 wood-burning clay hearths called chulas, to feed over 10,000 people every day.

It is the oldest surviving dance form of India on the basis of archaeological evidences. Odissi has a long, unbroken tradition of 2,000 years and finds mention in the Natyashastra of Bharatamuni, possibly written circa 200 BCE. Mahari Dance is one of the important dance forms of Odisha and originated in the temples of Odisha. History of Odisha provides evidence of the 'Devadasi' cult in Odisha. Devadasis were dancing girls who were dedicated to the temples of Odisha. The Devadasis in Odisha were known as 'Maharis' and the dance performed by them came to be known as Mahari Dance. Gotipua dance is another form of dance in Odisha. In Oriya colloquial language Gotipua means single boy. The dance performance done by a single boy is known as Gotipua dance.
There are many folk dances in east India, with the best-known being Jhijhiya, Jhumair, Domkach, Ghumura Dance, Sambalpuri and Chhau dance.
Jhijhiya is a cultural dance from the Mithila region. Jhijhiya is mostly performed at time of Dusshera, in dedication to Durga Bhairavi, the goddess of victory. While performing jhijhiya, women put lanterns made of clay on their head and they balance it while they dance.
Jhumair is a folk dance in Chota Nagpur Plateau region of Jharkhand, Chhattisgarh, Odisha and West Bengal. It is performed during harvest season and festivals accompanied by musical instrument such as Madal, Dhol, Bansuri, Nagara, Dhak and Shehnai.
Domkach is folk dance in the state of Bihar, Jharkhand, Chhattisgarh and Odisha. It performed during marriage in the house of Bride and groom.
Chhau is a form of tribal martial dance popular in the Indian states of West Bengal, Jharkhand and Odisha. There are three regional variations of the dance. Seraikella Chau was developed in Seraikella, the administrative head of the Seraikela Kharsawan district of Jharkhand; Purulia Chau in Purulia district of West Bengal; and Mayurbhanj Chau in Mayurbhanj district of Odisha.
Ghumura Dance Archaeological evidence shows cave paintings from the pre-historic period discovered by Gudahandi of Kalahandi and Yogi Matha of Nuapada district that represent the Ghumura and Damru, among other instruments. These paintings date to as early as 8000 BCE and from such painting the antiquity of musical instrument Ghumura and Damru can be imagined. The origin of Ghumura goes back to ancient times. There is a waterfall in the river valley of Indravati which was initially recognised by Chindak Naagas of Chakrakot. Many believe that Ghumura dance originated from this river valley and gradually spread into the areas between Indravati and Mahanadi, indicating this dance form belongs to the 10th century CE.
Bengali dance forms draw from folk traditions, especially those of the tribal groups, as well as from the broader Indian dance tradition. Dance forms of Bihar are another expression of rich traditions and ethnic identity. There are several folk dance forms that can keep one enthralled, such as dhobi nach, jhumarnach, manjhi, gondnach, jitiyanach, more morni, dom-domin, bhuiababa, rah baba, kathghorwa nach, jat jatin, launda nach, bamar nach, jharni, jhijhia, natua nach, bidapad nach, sohrai nach and gond nach.

#### Music of Odisha

Odissi music is a classical music in India originated from the eastern state of Odisha. Indian Classical music has five significant branches: Avanti, Panchali, Udramagadhi, Hindustani and carnatic. Of these, Udramagadhi exists in the form of Odissi music. Generally, Odissi is one of the classical dances of India performed with Odissi music. Odissi music got shaped during the time of famous Oriya poet, Jayadeva, who composed lyrics meant to be sung. By the 11th century CE folk music of Odisha existing in the form of Triswari, Chatuhswari, and Panchaswari was modified into the classical style. However, Odissi songs were written even before the Odia language developed. Odissi music has a rich legacy dating back to the 2nd century BCE, when king Kharvela, the ruler of Odisha (Kalinga) patronised this music and dance.
Like Hindustani and Carnatic systems, Odissi music is a separate system of Indian classical music and is having all the essential as well as potential ingredients of Indian Classical form. But it has not come to limelight due to apathy from the time of British rule in Odisha, want of its proper study, revival, propagation, etc. Despite the fact, the traditional music form could be saved and maintained in its pristine form. Thanks to the musicians particularly of Jaga Akhadas of Puri district, who could develop and maintain the music. The music movement of Odisha, however, took a different turn after independence.

Odisha has the third largest concentration of tribes constituting about one fourth of the total population. They are distributed over 62 tribal communities.
Odisha is the treasure house of Folk Songs which are sung on different festivals and specific occasions in their own enjoyment.

Of the bewildering variety of folk music of Odisha, mention may be made of Geeta, Balipuja Geeta, Kela Keluni Geeta, Dalkhai Geeta, Kendra Geeta, Jaiphula Geeta, Ghumura Geeta, Ghoda Nacha and Danda Nacha Geeta, Gopal Ugala and Osa-Parva-Geeta etc.
Bhajan, Janan, Oriya songs based on ragas, Rangila Chaupadi etc. are grouped under Light classical music, which forms an important segment of Oriya music. Sri Geetagovinda, Anirjukta Pravadha, Divya Manusi Prabandha, Chautisa, Chhanda, Chaupadi (now known as Odissi), Champu, Malasri, Sariman, nVyanjani, Chaturang, Tribhang, Kuduka Geeta, Laxana and Swaramalika are the various sub-forms, which individually or collectively constitute the traditional Odissi music.
