Baliraajgadh
Baliraajgadh is an archaeological site located in Madhubani district of Bihar, India. It has been claimed by some scholars to be the location of the ancient city of Mithila. The headquarter of the Ancient Mithila University was at the court of King Janaka in Mithila. Therefore, Balirajgadh is also the possible site of the Ancient Mithila University. It is the place from where most of the schools of the ancient Indian philosophy emerged. Nyaya Shastra, Logical sciences, Samkhya Shastra, Mimansa Shastra and many more Indian philosophy emerged from the Ancient Mithila University. In Xuanzang's record, two clans were linked with Vajji/Mithila by 646: Vaishali and Vrijji. Vaishali was both Buddhist and Hindu while Vrijji was predominantly Hindu and the capital of it Zhanshuna (占戍挐, possibly from Sanskrit "Cemśoṇa/Cansuna"). Excavations 
In 1938 Archeological Survey of India declared the ancient site of Balirajgadh as a site of national importance under the Ancient Monuments Preservation Act of 1904. The first excavation of the site was conducted in 1962-1963 by the Archeological Survey of India. The second and third excavations was conducted by the Directorate of Archaeology and Museums, Government of Bihar, in 1972-73 and 1974-75. In 2013-2014, Archeological Survey of India, Bihar circle again started the excavation of the site but due to the negligence of the government no proper results were there. Archeological Remains

According to regional legend, this was the capital of mythological asura king Bali. The son of Virochana and grandson of Prahlada, King Bali is believed to have been popular for his donations to the poor, Brahmins, scholars, and all those who came to his kingdom in expectation of financial help. Many scholars identify the site with the capital of King Janaka in Mithila. According to the Ramayana, Rama, Lakshmana and their guru, Vishvamitra, went to the Kingdom of Mithila from the Gautam Ashram in north-east direction. In the Ramayana, the capital of the Kingdom of Mithila is also known as Mithilapuri, which is also regionally identified with this site. History 
According to the historian Sahadev Jha, it was the capital of the Kingdom of Shakaditya in the 1st Century BC. Shakaditya was the younger brother of King Vikramaditya. In the 11th century AD, it was the capital of King Ballal sen of Sen dynasty. Some of the remains of Maurya period were also found here. So some scholars believe that some of the parts of this site may be built during Maurya period
