Dumka, headquarters of Dumka district, is a city and municipality in the state of Jharkhand, India. It was made the headquarters of the Santhal Pargana region which was carved out of Bhagalpur and Suri districts after The Great Santal Hul 1855. Presently, it is the commissionary headquarter of Santal Pargana division which has 6 districts.
It was bestowed the status of sub-capital of Jharkhand state. There are two theories as to how Dumka got its present name. The first one being that Dumka got its name from the santali word Dumk which mean "shunted" or "small". Back during the British Raj it was a small town compared to suri and bhagalpur and hencce the name. The other theory is that Dumka derives its name from a Persian word damin-i-koh, which means 'skirts (an edge, border or extreme part) of the hills'. The Mughals assigned this name to this and nearby areas on account of presence of hillocks and undulating terrain.
