Nālandā (Hindi/Sanskrit/Pali: नालंदा) is the name of an ancient center of higher learning in Bihar, India. The site of Nalanda is located in the Indian state of Bihar, about 55 miles south east of Patna, and was a Buddhist center of learning from 427 to 1197 CE. It has been called "one of the first great universities in recorded history". Some buildings were constructed by the Mauryan emperor Ashoka the Great (273–232 BCE) which is an indication of an early establishment of the Buddhist learning center Nalanda. The Gupta Empire also patronized some monasteries. According to historians, Nalanda flourished between the reign of the Gupta king Śakrāditya (also known as Kumāragupta, reigned 415-55) and 1197 CE, supported by patronage from Buddhist emperors like Harsha as well as later emperors from the Pala Empire. The complex was built with red bricks and its ruins occupy an area of 14 hectares. At its peak, the university attracted scholars and students from as far away as China, Greece, and Persia.Nalanda was sacked by Turkic Muslim invaders under Bakhtiyar Khalji in 1193, a milestone in the decline of Buddhism in India. The great library of Nalanda University was so vast that it is reported to have burned for three months after the Mughals set fire to it, sacked and destroyed the monasteries, and drove the monks from the site. In 2006, Singapore, China, India, Japan, and other nations, announced a proposed plan to restore and revive the ancient site as Nalanda International University.
