Vikramshila, a prominent seat of Buddhist learning in ancient India, flourished in the Bhagalpur district of Bihar (present-day Antichak village near Kahalgaon). Established during the Pala Empire (8th-9th centuries CE), Vikramshila rivaled the illustrious Nalanda University. Its archaeological remains serve as a window into this esteemed institution, offering valuable insights into its historical significance and the vibrant intellectual culture it fostered. Vikramshila University was established at the end of the eighth century by King Dharmapala of Bengal (783 to 820 AD), successor to Gopala, the founder of the Pala dynasty, at a time when the influence of Nalanda University was waning. Atisha Dimpakara was one of Vikramashila abbots. In order to be admitted, students had to answer correctly to test questions asked by the teachers present at all six main gates. It was one of the three most important Buddhist Mahaviharas of its time in India, along with Nalanda and Odantapuri. Its location is now the site of Antichak village near Kahalgaon, Bhagalpur district in Bihar. It was one of the largest Buddhist maha vihara, with more than one hundred teachers and about one thousand students. It produced eminent scholars who were often invited by foreign countries to spread Buddhist learning, culture and religion including Atiśa and Ratnakarasanti.
