Gobar (reign 1675–1675) was the king of the Ahom kingdom for a duration of about three weeks. He was the first king from Tungkhungia line of Ahom dynasty, and the father of Gadadhar Singha, a later Ahom king. He was installed by Debera Borbarua, a powerful officer in the capital Garhgaon. Gobar was the last king installed by Debera before both were removed and executed by the Saraighatia Ahom officers under the leadership of Atan Burhagohain.
Gobar was the son of Saranga Gohain, the son of Suteng, the third son of Suhungmung. His grandfather Suteng Namrupia Raja was the founder of the Tungkhungia line of the Ahom dynasty, to which the final set of Ahom kings of Assam belonged.
After the deposition and execution of Udayaditya Singha in 1672, the Ahom kingdom entered into a period of weak kings, with de facto power wielded, successively, by three prominent ministers: Debera Barbarua, Atan Burhgohain, and Laluk Sola Borphukan. Debera Borbarua, the first such minister, rose in prominence and exerted complete authority over the administration in Garhgaon, the Ahom capital, at a time when many powerful ministers were at guard at newly-occupied Guwahati soon after the Battle of Saraighat (thus these officers were called Saraighatias). Debera’s period of control saw three kings being deposed and put to death, within a short period of about three years. After Udayaditya Singha, he installed and subsequently deposed two others: Ramdhwaj Singha and Suhung. Gobar Gohain from the Tungkhungia line was the last king he installed, which he did in May 1675.
After installing Gobar on the throne, Debera assumed dictatorial power. By a series of cold-blooded murders Debera purged the capital of his opponents and rivals, though most of the powerful Ahom nobles were stationed at Guwahati. Debera then turned his attention to the Ahom nobles stationed at Guwahati. Debera sent his agent Lao Deka, brother of Laluk Sola Borphukan, to Guwahati under the alleged orders of the king and summoned the following nobles to the capital: Ghorakonwar Phukan ex-Borbarua, the brother of Tangachu Rajkhowa, Sologuria Rajkhowa and his son Chanda Rajkhowa, Opar Dayangia Rajkhowa and his brother, and Medelial Rajkhowa and his son. When they reached Garhgaon, they were taken to Laotoli where they were killed. Debera also planned to kill Lao Deka, the younger brother of Laluk Sola Borphukan, but his execution was postponed to an appropriate occasion in future.
In order to secure his position for the future, Debera Borbarua planned to get rid of Atan Burhagohain and Laluk Sola Borphukan. Two agents of Debera—Betmela and Lao Deka of Dihingia Khatowal Chetia family—were dispatched to Guwahati to bring Laluk Sola Borphukan to Garhgaon. They carried with them an order purportedly from the king. They were also instructed by Debera to bring the Burhagohain with them if possible. Betmela and this lieutenant Lao Deka reached Guwahati and communicated the royal orders to the nobles of Guwahati at the Dopdar or the Borphukan’s court. Since it was evening, the officers retired to their respective camps having postponed their deliberations till next day. Khamat Pachani, the son of the Burhagohain arrived at Guwahati the next day and warned his father not to follow the royal orders as they were actually from Debera Borbarua. He also described the fate of the previous officers who were executed after being called from Guwahati to the capital. Atan Burhagohain along with Laluk Sola Borphukan held consultations with the Phukans, the Rajkhowas and the Hazarikas stationed at Guwahati to discuss their future course of action. The officers consulted together and said to Atan Burhagohain,-‘Your Lordship is living in flesh and blood. One single man Debera is making and unmaking kings and deposing and killing us as well. Your lordship should come to our rescue at this critical juncture. We the people have accepted you as our head, and your lordship should not disclaim us.’ Saying this the officers bowed down to Burhagohain seven times. The Burhagohain said in reply,-‘Now that the people have acknowledged me as their leader I am never going to leave them.’ The Phukans, Rajkhowas, and others of the Guwahati establishment entered into a solemn league and covenant to abide by the directions of the Burhagohain, and support each other in all circumstances and events. They placed before them articles sacred to the Vaishnavas,- the manuscripts of Gita, Bhagavat and Ratnavali; Salagram, copper, and the tulasi or basil plant; and in the presence of the Brahmans they took the following oath,-“If we act contrary to the plans and orders of Your Excellency all the merits which we have earned hitherto will be nullified, our ancestors will be doomed to perdition and go to hell. Besides, we promise not to desert one another.“
