Duliajan is an industrial town of Dibrugarh district in the Indian state of Assam located in the upper north-east corner of India.

Thus, when a new oil town was constructed in this area, to honour the palanquin bearers, it became a natural choice for the historical name of Duliajan.

As per another legend, Dulia khel (a sub-community of Ahom) first settled on the bank of a small rivulet Duriajan which is in the village of Kachari Pathar.

Immediately after ascending the throne, Supinfa investigated the killing of his father and found one of his minister Laturban and his sons as the main conspirators.

Oil India formally set up its own organization on 1 January 1962 to look after all aspects of drilling and exploration operations, with its headquarters at Duliajan, then known as Zaloni in the Nahorkatiya area.

The establishment of Duliajan oil town may be said to have brought about an era of petroleum industries in the district of Lakhimpur which then comprised the present districts of Dibrugarh and Tinisukia on the south bank and Lakhimpur and Dhemaji on the north bank of the river Brahmaputra.

[5] As of the 2011 India census, Duliajan had a population of 28,626:- 14,898 males and 13,728 females, giving a sex ratio 921 which was lower than the state average of 958.

As the closest railway junctions are at Dibrugarh and Tinsukia (which is at a distance of only 20 km), most trains do not stop at Duliajan even when they pass through the town.

Easily accessible by road by a branch-off (40 km) from national highway NH-37, Duliajan is also well connected to the nearest district headquarters of Tinsukia and Dibrugarh.

Buses, both private and ASTC, on a daily basis, ply to Guwahati, Nagaon, Jorhat, Dibrugarh, Tinsukia and even to parts of Arunachal Pradesh.

In Nehru Maidan, there is Duliajan Athletics Club which is the body of Assam Athletics Association affiliated with athletics, football, cricket, lawn tennis, table tennis, golf, taekwondo, badminton, baseball, kabaddi college level, chess, kho-kho in school level, handball at college level, boxing, kick boxing, swimming, squash and martial arts.

[7] The famous football club from Duliajan, Oil India FC is a member of the AIFF and competed in the I-League 2nd Division for three seasons.

It is the manifestation of the concept of ancestor worship that the Ahoms share with other peoples originating from the Tai-Shan stock.
