West Singhbhum district
West Singhbhum or Pashchimi Singhbhum is one of the 24 districts of Jharkhand state, India. It came into existence on 16 January 1990, when the old Singhbhum district (then in Bihar) was bifurcated. Chaibasa is the district headquarters. The district is bounded on north by Khunti district, on the east by Saraikela Kharsawan district of Jharkhand, on the southeast by Mayurbhanj district of Odisha, on the south by Kendujhar district of Odisha, and on the west by Simdega district of Jharkhand and Sundergarh district of Odisha. History 
Several Iron slags, microlith, Potsherds have been discovered from Singhbhum district which are from 1400 BCE according to Carbon dating age. Remains of a large city was excavated by Archaeological Survey of India in the village of Benisagar in West Singhbhum, suggesting continuous habitation in the region from 5th to the 16th-17th century. West Singhbhum is one of the oldest districts of Jharkhand. After the British conquest of Kolhan in 1837, a new district was consequently constituted to be known as Singhbhum with Chaibasa as its headquarters. Subsequently, three districts, namely East Singhbhum, West Singhbhum and Seraikela Kharsawan have been carved out of erstwhile Singhbhum district. West Singhbhum district came into existence when the old Singhbhum District bifurcated in 1990. With 9 community development blocks the Eastern part became East Singhbhum district with Jamshedpur as its headquarters and with remaining 23 blocks the larger Western part became West Singhbhum district with Chaibasa as its headquarters. In 2001 West Singhbhum again divided into two parts. With 8 blocks Saraikela-Kharsawan district came into existence. At present West Singhbhum remains with 18 blocks and three administrative sub-divisions. There are several accounts relating to the origin of the name of the district:
According to one the name Singhbhum, or the land of "Singhs" has been derived from the patronymic of the Singh Rajas of Porahat, the junior branch of whom went on to found the ruling "Singh Deo" family of Saraikela State. A second account suggests that the name is a corrupt form of the 'Singh Bonga' the principal deity of the district's tribal Bhumij-Munda population. It is currently a part of the Red Corridor.
