Bihar (; Hindi pronunciation: [bɪˈɦaːr] (listen)) is a state in eastern India. It is the third-largest state by population and twelfth-largest by territory, with an area of 94,163 km2 (36,357 sq mi). Bihar borders Uttar Pradesh to its west, Nepal to the north, the northern part of West Bengal to the east, and with Jharkhand to the south. The Bihar plain is split by the river Ganges, which flows from west to east. Bihar is also the world's fourth-most populous subnational entity.On 15 November 2000, southern Bihar was ceded to form the new state of Jharkhand. Only 11.3% of the population of Bihar lives in urban areas, which is the lowest in India after Himachal Pradesh. 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 languages are Hindi and Urdu, although other languages are common, including Maithili, Magahi, Bhojpuri and other Languages of Bihar. 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 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 is Mithila which was an early centre of learning and the centre of the Videha kingdom.However, since the late 1970s, Bihar has lagged far behind other Indian states in terms of social and economic development. It's gained a highly negative reputation among the denizens of India to a degree where being called 'Bihari' is an insult. Many economists and social scientists claim that this is a direct result of the policies of the central government, such as the freight equalisation policy, its apathy towards Bihar, lack of Bihari sub-nationalism, and the Permanent Settlement of 1793 by the British East India Company. The state government has, however, made significant strides in developing the state. Improved governance has led to an economic revival in the state through increased investment in infrastructure, better healthcare facilities, greater emphasis on education, and a reduction in crime and corruption.

Nalanda (Nālandā, pronounced [naːlən̪d̪aː]) was a renowned Buddhist monastic university in ancient Magadha (modern-day Bihar), India. Considered by historians to be the world's very first residential university, and among the greatest centers of learning in the ancient world, it was located near the city of Rajagriha (now Rajgir) and about 90 kilometres (56 mi) southeast of Pataliputra (now Patna), operating from 427 to 1197 CE. Nalanda played a vital role in promoting the patronage of arts and academics during the 5th and 6th century CE, a period that has since been described as the "Golden Age of India" by scholars.Nalanda was established during the Gupta Empire era, and was supported by numerous Indian and Javanese patrons – both Buddhists and non-Buddhists. Over some 750 years, its faculty included some of the most revered scholars of Mahayana Buddhism. Nalanda Mahavihara taught six major Buddhist schools and philosophies such as Yogacara and Sarvastivada as well as subjects such as grammar, medicine, logic and mathematics. The university was also a major source of the 657 Sanskrit texts carried by pilgrim Xuanzang and the 400 Sanskrit texts carried by Yijing to China in the 7th century, which influenced East Asian Buddhism. Many of the texts composed at Nalanda played an important role in the development of Mahayana and Vajrayana Buddhism including the Mahavairocana Tantra and the Bodhisattvacaryāvatāra of Shantideva. It was sacked and destroyed by the troops of Muhammad Bakhtiyar Khalji, partly restored thereafter, and continued to exist till about 1400 CE. Today, it is a UNESCO World Heritage Site.In 2010, the Government of India passed a resolution to revive the famous university, and a contemporary institute, Nalanda University, was established at Rajgir. It has been listed as an "Institute of National Importance" by the Government of India.
