s in Western Dooars till the
Duar War of 1865 The Dooars belonged to the
Kamata Kingdom under the
Koch dynasty; In the early 17th century, the combined forces of Ahoms and Koches temporarily checked the Bhutia's transgression. During this period two important Duars on the Darrang frontier, Buriguma and Killing were under
Ahoms control. During the
Ahom–Mughal conflicts in the mid-17th century, the Bhutias attempted to extend their authority as far as
Gohain Kamal Ali road. In the reign of Ahom king
Jayadhwaj Singha, the
Druk Desi of Bhutan requested the transfer of these Duars to Bhutan. Therefore, an agreement was drawn, and the Darrang Duars went to the hands of Bhutias on the condition of annual tribute to the Ahoms. The Darrang Duars were also surrendered to Ahoms annually for four months from June to October. These Duars were properties of
Ahom government, but the
Druk Desi of Bhutan took possession of them in last phase of 18th century when the Ahoms were engaged in
internal rebellions. This region was controlled by the kingdom of Bhutan when
British India annexed it in 1865 after the
Duar War under the command of Captain Hedayat Ali. Bhutan lost almost one-fifth of its area in this war. The area was divided into two parts: Western Dooars and Eastern Dooars. The Western Dooars were under the Kingdom of
Cooch Behar State from 1586 to 1949, and the Eastern Dooars under the Kingdom of
Koch Hajo. Under the Koch government, the officer-in-charge of the Duars were called
Subahdar. Similar office existed under the Bhutan government, the
Subah was selected by the provincial governors called
Ponlops. The Ahom government managed the Duars through Duarieas. The other two Dooars were the Kamrup Duars and Darrang Duars. The Eastern Dooars was merged with
Goalpara district in
Assam, the Kamrup Dooars was merged with
Kamrup district, the Darrang Dooars was merged with
Darrang District and the western part was turned into a new district named
Western Dooars. Again in the year 1869, the name was changed to
Jalpaiguri district.
