Barahathwa[1] is a municipality of the Sarlahi District in the Janakpur Zone of central Nepal. The municipality was established on 19 September 2015 by merging the existing Barahathwa, Murtiya, Hajariya, sundarpur chuhadwa village development committee su.chu. and Laukat village development committees (VDCs).[2] [3] The center of the municipality is established in the former VDC Office of Barahathwa Bazaar. After merging the four VDCs' populations, it had a total population of 50,424 according to 2011 Nepal census.[4] The population is excepted to reached 100,000 in this decade.[5]
The Nepali government announced in 2015 the creation of 26 new municipalities. With this announcement Barahathawa was upgraded to a municipality of Nepal; previously it was merely a proposed municipality. The adjoining villages, or VDCs, of Barahathawa, Shreepur, Murtiya, Hajariya, Janakinagar, Laukat and Sundarpur chuhadwa were merged with Barahathawa to upgrade it to the status of a municipality.
