Sivasagar, formerly known as Rangpur, was the capital of the Ahom Kingdom from 1699 to 1788. The Ahoms ruled Assam, virtually without interruption, for six centuries, until their kingdom fell to the Burmese in 1819 and their ruling class was all but wiped out.
The province was liberated by the British in 1825 but, owing to the state of anarchy which prevailed, it was completely annexed in 1826. For administrative purposes it was divided into three sub-divisions.
It is said that the original name of Sivasagar was - 'Kalansupar' after the name of 'Kalansu Gohain' who resided in a village originally existed in the place where currently the Sivasagar tank is located.

This town's main feature is the water body from which it takes its name. This is a 257-acre (1.04 km2) tank, also known as the Borpukhuri, which is at a higher elevation than the rest of the town, with three temples ("Dol"s in Assamese) on its banks. Of these temples, the most prominent is the Sivadol, standing tall at 104 feet (32 m), drawing large crowds on Shiv Ratri. The other temples are the Vishnudol and Devidol. The temples were built by Kuwori Ambika, wife of Swargadeo Siba Singha, in 1734.
