Saharsa is one of the thirty-eight districts of Bihar, India. Saharsa city is the administrative headquarters of this district. Saharsa district is a part of the Kosi Division and it became a district on 1 April 1954 and has subsequently become smaller with other districts being carved from it, most notably Madhepura in 1981. Saharsa is located in the Mithila region, one of the earliest centers of Brahminical civilization in India. Saharsa is considered as the heart of whole Mithila region. it is the place which gave birth to legends such as like Mandana Misra, Laxminath Gosain, Ubhai Bharti, etc. The region of Bangaon and Mahisi is known for producing a large number of civil servants. Saharsa is part of the Mithila region. Mithila first gained prominence after being settled by Indo-Aryan peoples who established the Mithila Kingdom (also called Kingdom of the Videhas). During the late Vedic period (c. 1100–500 BCE), Videha became one of the major political and cultural centers of South Asia, along with Kuru and Pañcāla. The kings of the Videha Kingdom were called Janakas. The Videha Kingdom was later incorporated into the Vajjika League, which had its capital in the city of Vaishali, which is also in Mithila. Mandan Mishra whose conversation with the Shankaracharya was considered one of the most intellectual conversations in the world was done in Mahismati village, nowadays Mahisi village. During the Dharma Vijaya yatra of Adi Shankara, He visited Mahisi village (then called Mahishmati) to debate Mandana Misra. After winning in all discussions in all over the nation, He lost the Sastrartha there. Earlier, the Saharsa district was part of the Munger and Bhagalpur districts. On 1 April 1954 it was made a district of its own. It was also made headquarters of Kosi division on 2 October 1972, comprising Saharsa, Purnia and Katihar district, with its headquarters at Saharsa. Similarly a new Civil Sub-Division Birpur was created on 1 December 1972, consisting of 24 development blocks, including Raghopur, Chhatapur, Basantpur and Nirmali, which were previously under Supaul subdivision of the district.
