The United Liberation Front of Asom (ULFA) is an armed separatist insurgent organisation, that operates in the Indian state of Assam. It seeks to establish an independent sovereign nation state of Assam for the indigenous Assamese people through an armed struggle via the Assam conflict. The Government of India banned the organisation and designated it as a terrorist organisation in 1990, while the United States Department of State lists it under "other groups of concern".
According to ULFA sources, it was founded on 7 April 1979 at Rang Ghar and began operations in mid 1980s. ULFA established ties with the Nationalist Socialist Council of Nagaland in 1983 and with the Burma-based Kachin Independent Army in 1987. Military operations against the ULFA by the Indian Army began in 1990 and continue to this day. On 5 December 2009, the chairman and the military operation commander of ULFA was taken into Indian custody. In 2011, there was a major crackdown on ULFA in Bangladesh under the previous regime of Awami League, which greatly assisted the government of India in bringing ULFA leaders to talks. In January 2010, a portion of ULFA softened its stance and dropped demands for independence as a condition for talks with the Government of India.
On 3 September 2011, a tripartite agreement for "Suspension of Operations" agreement was signed by the Indian government, the Assam government and the ULFA.
History The ULFA was founded in courtyard of historic amphitheatre–Rang Ghar on 7 April 1979 in Sivasagar, Assam by a group of young men that included Bhupen Borgohain, Bhimkanta Buragohain, Tarun Gogoi, Pradip Gogoi, Bhadreshwar Gohain and Budheswar Gogoi. The organisation's purpose was to engage in an armed struggle to form a separate independent state of Assam.
During its peak days in the late 80s and 90s, it had support among many of the Assamese people of the Brahmaputra valley. The majority of the supporters felt that a powerful organization was necessary to get the voice of a peripheral region heard, to the central government. But gradually, the organisation's emphasis on illegal means and smuggling of weapons in the name of furthering the 'revolution' led to violence throughout the state. It witnessed a period marked by growing disillusionment and anger amid supporters.
In the conflict, many civilians were killed and several thousand were permanently maimed and displaced. It is estimated that more than 10 thousand local youths were killed and disappeared during that period. In the process, owing to the twin factors of increasing operations by the security forces and dwindling support among its core sympathisers, ULFA's importance in Assam has been declined drastically.
Recruiting for the front did not begin until 1983. Soon after it finished recruitment in 1984, it began to seek out training and arms procurement from other groups such as the Kachin Independence Army (KIA) and the Nationalist Socialist Council of Nagaland (NSCN). In 1986, it launched a fundraising campaign across India. It then began to set up camps in Tinsukia and Dibrugarh but was soon declared a terrorist organization by the government on 7 November, under the Unlawful Activities (Prevention) Act.
In less than a decade of its formation, the ULFA emerged as one of the most powerful insurgent outfits in Southeast Asia, largely because of the immense popularity, it enjoyed during the first decade of its struggle as well as its economic power which in turn helped it in bolstering its military capabilities. In the early 1990s, ULFA launched an armed campaign against Indian forces, political opponents, and blasted rail links. In July 1991, the front captured and held 14 people for ransom, included in the abductees was an engineer and a national of the Soviet Union. From the 1990s, the ULFA have continued to carry out attacks.
Till the late 2000s, it maintained a number of camps in Bangladesh, where members were trained and sheltered away from Indian security forces. In April 2004, Bangladesh police and Bangladesh Coast Guard intercepted massive amounts of illegal arms and ammunition at Chittagong, being loaded into 10 trucks. A total of 50 were charged with arms smuggling and arms offenses, including former high-level Bangladesh political appointees including ministers of the Bangladesh Nationalist Party and Bangladesh Jamaat-e-Islami and NSI military officers, as well as prominent businessmen, and Paresh Baruah, the chief of ULFA who was then living in Dhaka. He later fled the country."Ex-Industries Secretary Nurul Amin was informed of the 10-truck arms smuggling: Mobin Hossain" , Bangladesh Sangbad Sangstha (BSS), 28 November 2012. Retrieved 1 May 2013
They had also maintained camps in Bhutan, which were destroyed during Operation All Clear by the Royal Bhutan Army aided by the Special Frontier Force in December 2003. These camps housed combatants and non-combatant families of ULFA members.
ULFA maintained close relationships with other separatist organisations like NDFB, KLO and NSCN (Khaplang).
In 2008, News Services reported citing Indian police and intelligence officials reported ULFA's commander-in-chief Paresh Baruah had taken refuge in Yunnan Province of China, along China-Myanmar border, due to continued losses incured to his organization. The report also stated that a group of militants had also taken refuge along with him. Paresh Baruah had previously visited China in the 1980s. In December 2003, China spurned ULFA's chairman Arabinda Rajkhowa appeal to provide safe passage to the rebels from Bhutan.
On 13 July 2025, ULFA(I) claimed that the Indian Army launched drone attacks on camps in Sagaing Region, Myanmar. Indian officials denied knowledge of any cross-border operations recently targeting ULFA(I).ULFA(I) claims missile strikes killed its commanders in Myanmar. July 13, 2025. The Hindu.
Secret killings of the family members of militants During the second government of AGP leader Prafulla Kumar Mahanta, as a part of his government's counter-insurgency strategy, unidentified gunmen had assassinated a number of family members of ULFA leaders. With the fall of this government following elections in 2001, the secret killings stopped. Dinesh Barua, the elder brother of Paresh Barua, was taken from his house at night by unidentified Assamese men, Later his body was found lying near a cremation center in Chabua. ULFA's self-styled Publicity Secretary, Mithinga Daimary, also had his five family members killed during this period.
Government investigations into the killings culminated in the report of the "Saikia Commission", presented to the Assam Assembly on 15 November 2007. The report describes how the killings were organised by Prafulla Mahanta, then the Assam Home Minister. They were executed by the police. The gunmen were former members of ULFA who had surrendered to the government. They approached their targets at home, at night, knocking on the door and speaking in Assamese to allay suspicion. When the victims answered the door, they were shot or kidnapped to be shot elsewhere."Saikia Commission indicts former Chief Minister Mahanta for 'secret killings'", The Hindu, 16 November 2007
