Bihar is a state in eastern India. It lies  on the Gangetic plain, with Uttar Pradesh to its west, West Bengal to its south and east, and  with Nepal to  its north. The Bihar plain is divided into two unequal halves by the  river Ganga which flows through the middle from west to east.
Bihar can be grouped into four regions based on river boundaries. These  four regions have very similar languages - Angika, Bhojpuri, Magadhi and  Maithili spoken in respective regions. The languages are collectively  known as 'Bihari' and are decedents of the ancient language of Magadhi  Prakrit, the language spoken by the Buddha and the language of the  ancient kingdom of Magadha.

History
 Bihar has a glorious past. Bihar  was known as Magadha in ancient times. It was a center of power,  learning and culture. The Maurya empire as well as one of the world's  greatest pacifist religions, Buddhism, arose from Magadha. Bihari  empires, like the Maurya and the Gupta, unified large parts of South Asia under a central rule. Pataliputra (modern Patna), the  capital of Magadha, was an important center of Indian civilization. Many  important non-religious books like Arthashashtra and Kamasutra were  composed here 2000 years back. Vaisali, one of the first known republic,  existed here since before the birth of Mahavira (c. 599 BC).  
The state suffered immensely due to Hunnic and later Muslim  invasions, and the old traditions of culture and learning was almost  lost by the end of 12th century. The Muhammad Bin Bakhtiar Khilji in  12th century C.E. destroyed many of the viharas (Buddhist sanghas) and  the famed universities of Nalanda and Vikramshila. Thousands of Buddhist  monks were massacred. Bihar lost its importance in the medieval period  though it rose to prominence for a brief period during the rule of Sher  Shah Suri in the 15th century. Foreign invaders often used abandoned  viharas as military cantonments. The word Bihar have come from the large  number of viharas thus employed in the area. Originally Bihar was name  of a town, which was headquarter of the Muslim invaders in Magadha, in  the medieval period. The headquarter was later on shifted, from Bihar to  Patana (current Patna),  by Sher Shah Suri and the establishments in those time started calling  Magadha by the name Bihar. The town of Bihar still exists is also known  as Bihar-Sharif, which is located in Nalanda District, near the famous  ruins of the Nalanda University.  
The culture and lifestyle of the Biharis haven't changed much  over the centuries. Resurgence in the history of Bihar came during the Indian independence  struggle against the British rule.
