Birbhum district

Birbhum district (Bengali pronunciation: [biːrbʰuːm]) is an administrative unit in the Indian state of West Bengal. It is the northernmost district of Burdwan division—one of the five administrative divisions of West Bengal. The district headquarters is in Suri. Other important cities are Rampurhat, Bolpur and Sainthia. Jamtara, Dumka and Pakur districts of the state of Jharkhand lie at the western border of this district; the border in other directions is covered by the districts of Bardhaman of Purba Bardhaman, Paschim Bardhaman and Murshidabad of West Bengal.

Often called "the land of red soil", Birbhum is noted for its topography and its cultural heritage which is somewhat different from the other districts in West Bengal. The western part of Birbhum is a bushy region, a part of the Chota Nagpur Plateau. This region gradually merges with the fertile alluvial farmlands in the east.

This district saw many cultural and religious movements in history. Tarapith is a Hindu pilgrimage site located at 9km distance from Rampurhat city, which is one of the prominent places in Birbhum where every day a large number of pilgrims from across the country, neighboring states, and even abroad gather.This town is particularly known for the Tarapith Temple and its adjoining Hindu crematory ground. The Visva Bharati University at Santiniketan, established by Rabindranath Tagore, is one of the places Birbhum is known for. Many festivals are celebrated in the district, including Poush Mela.

Birbhum is primarily an agricultural district with around 75.09% of the population being dependent on agriculture. Principal industries of the district include cotton and silk harvesting and weaving, rice and oilseed milling, lac harvesting, stone mining and metalware and pottery manufacture. Bakreshwar Thermal Power Station is the only heavy industry in the district.

The name Birbhum comes probably from the term 'land' ('bhumi') of the 'brave' ('bir') or Bir king'). Another theory says that the district bears the name of Bagdi king Bir Malla, who ruled in the area from 1501 to 1554 CE. Bir in the Santali language means forests; therefore, Birbhum could also mean a land of forests.

Situated between 23° 32' 30" (right above the tropic of cancer) and 24° 35' 0" north latitude and 87° 5' 25" and 88° 1' 40" east longitudes, and about 4,545 square kilometres (1,755 sq mi) in area, this district is triangular. River Ajay forms the southern base and the apex of the triangle points north. The river forms the boundary between the districts of Birbhum and Bardhaman. The state of Jharkhand is at the northern and the western border of Birbhum and Murshidabad is at the east.

Geographically, this area lies at the northeastern end of the Chota Nagpur Plateau, as it slopes down and merges with the alluvial plains of the Ganges. In the district there is only hilly area of natural rock formation situated near Dubrajpur town called Mama Bhagne Pahar (Hills). The western portion of the district is historically known as Vajjabhumi or Bajrabhumi. It is an undulating upland that is generally barren. The comparatively more fertile eastern portion, constituting the northeastern Rarh region, merges with the Gangetic plain. Vajjabhumi is included in the Rarh region, and the rest of Rarh is called Sumha to differentiate it from Vajjabhumi.

The climate on the western side is dry and extreme but is relatively milder on the eastern side. During summer, the temperature can shoot well above 40 °C (104 °F) and in winters it can drop to around 6 °C (43 °F). Rainfall is higher in the western areas as compared to the eastern areas. The annual average rainfall in Rajnagar is 1,405 millimetres (55.3 in) and in Nanoor it is 1,212 millimetres (47.7 in), mostly in the monsoon months (June to October).
