Subodh Kumar Dutta and Late Sunil Chakravorty who lead the freedom movement in the erstwhile Sub-division.

Nagendranath Choudhury was a prominent Congress-leader; Pandit Jawaharlal Nehru called on him in his house during his visit to Hailakandi in 1939.

His brother Manmatha Choudhury was a captain in the Azad Hind Fauj formed by Subhash Chandra Bose.

In 1946, when India was still under British rule, Mr. Abdul Matlib Majumder became an MLA and also Cabinet Minister of Assam.

Netaji Subhash Chandra Bose and Pandit Jawaharlal Nehru visited Hailakandi in 1939 and 1945 respectively at the invitation of Mazumdar to strengthen the freedom movement as well as the Congress party in southern Assam.

To counter the rising popularity of Muslim League, he successfully organised the Jamiat Ulema-e-Hind movement in Assam.

That victory virtually sealed the hopes and aspirations of the Muslim League to include southern Assam in Pakistan.

On the eve of partition, hectic activities intensified by the Muslim League as well Congress with the former having an edge.

Mazumdar along with Basanta Kumar Das (then Home Minister of Assam) travelled throughout the valley organising the Congress and addressing meetings educating the masses about the outcome of partition on the basis of religion.

[6][8] Mazumdar was the leader of the delegation that pleaded before the Radcliffe Commission that ensured that a part of Sylhet (now in Bangladesh) remains with India despite being Muslim-majority (present Karimganj district).

[9] Moulvi Mazumdar joined as a Cabinet Minister of Assam in 1946 with the portfolios of Local Self-Government, Agriculture and Veterinary.

In 1947, India became free from British rule, when Mazumdar again took charge of the same departments in Gopinath Bordoloi's cabinet as the only Muslim minister (Moulana Tayyebulla was inducted in 1948) and also the lone member from the entire Barak valley region.

A large number of people lost their lives owing to violence, which resurfaced with more ferocity in 1950.

He then became the Minister for Law, Social Welfare and Political Sufferers in Bimala Prasad Chaliha's cabinet.

During the Bangladesh's war of liberation in 1970–71, he was in charge of relief-&-rehabilitation of the thousands of refugees who fled the then East Pakistan.

As Chairman of Madrassah Board, he initiated modernisation of these theological schools and is also credited for the introduction of English and science in the curriculum of madrassas of Assam.

Today's "Assam-type house" is entirely his concept which gained vast popularity in the earthquake zones.

Hailakandi district occupies an area of 1,327 square kilometres (512 sq mi),[13] comparatively equivalent to Qeshm Island of Iran.

The forests of Hailakandi district were once rich in wildlife but now vanishing due to human onslaught.

[21] According to the 2011 census, Hailakandi district has a population of 659,296,[1] roughly equal to the nation of Montenegro[24] or the US state of North Dakota.
