the district

Ranchi district is the most populous district of Jharkhand state in eastern India. Ranchi, the capital of Jharkhand, is the district headquarters. It was established as a district in 1899.

Iron slag, potsherds and iron tools have been found in the Chota Nagpur plateau dated to 1400 BCE. Magadha Empire exercised indirect control over the territory, which lasted until the reign of the Ashoka. Kalinga rulers are believed to have ravaged the region during their expeditions to Rajgir and Pataliputra. Armies of Samudra Gupta passed through the region on their expedition to Deccan. Khukhragarh was one of the capitals of Nagvanshi dynasty. With the expansion of the Mughal Empire, the Nagvanshis were forced to pay tribute, but they continued to rule and administer independently until the advent of the East India Company. Thakur Vishwanath Shahdeo, Pandey Ganpat Rai, Tikait Umrao Singh and Sheikh Bhikhari played pivotal role in Indian Rebellion of 1857. During the period of the British Raj, Adivasis and other locals of the Chotanagpur Plateau continued to oppose the subjugation by the British, and the region witnessed a number of uprisings and revolts.

Ranchi Hundru Falls, Jonha Falls, and Panchghagh Falls. The Subarnarekha river and its tributaries constitute the local river system. Dams in Kanke, Rukka and Hatia have been built over these channels to cater to the water requirements of majority the population. Ranchi has a hilly topography and its combination with dense tropical forests ensures that it enjoys a comparatively moderate climate compared to the rest of the state. Previously, it was accorded a 'hill station' status during the British rule. Rapid population growth and industrialization have caused considerable change in the weather pattern and rise in average temperatures. This has resulted in gradual loss of this "Hill Station" like status. It also has numerous dams constructed in different regions of the city inside and on the outskirts.

In 2006 the Indian government named Ranchi one of the country's 250 most backward districts (out of a total of 640). In the aspirational districts, Ranchi have improved.

Presently, Ranchi district is divided into 2 sub divisions and 14 administrative blocks.
