About the Partition of India and the Sylhet Referendum
The partition of India was announced through the Mountbatten Plan on 3 June 1947. Under this plan, British India was to be partitioned into two independent countries — India and Pakistan — and the two provinces of Bengal and Punjab were themselves to be partitioned. Assam did not escape this upheaval. Among the districts of Assam, it was Sylhet district that was to decide its own fate through a referendum. Sylhet was a Muslim-majority district at the time of partition, and the referendum was held to let its people choose whether to stay with Assam (India) or to join East Bengal (Pakistan).
The Sylhet Referendum was held on 6 July 1947. The adult population of the Sylhet district took part in it. The outcome was that a majority of voters voted in favour of joining East Bengal, that is, Pakistan. In other words, the majority in the Sylhet Referendum voted for Pakistan, not India. Following this result, Sylhet was detached from Assam and merged with East Bengal (later East Pakistan) in 1947. Sylhet did not remain a part of India after the referendum. This was a painful loss for Assam, and it changed the province permanently.
The consequences for Assam were profound. First, Assam’s area shrank because a whole district was taken away. Second, Assam’s population decreased. Third, and somewhat paradoxically, the proportion of Assamese-speaking people in Assam increased — because the district that left had a large Bengali-speaking and Muslim-majority population, its removal raised the relative share of Assamese speakers in the remaining province. At the same time, the hill districts of Assam remained with India: the Khasi, Jaintia, Garo, Lushai (Mizo) and Naga hills did not go to Pakistan. These hill areas were later reorganised into separate states, but in 1947 they stayed within India. The referendum therefore had a double message for Assam’s leaders: on the one hand, a part of Assam was lost; on the other hand, the rest of Assam, including the hills, remained in India and had to be protected.
This is why the Sylhet Referendum is always studied together with the grouping issue. The loss of Sylhet and the earlier danger of being grouped with Bengal taught the leaders of Assam the pressing need to protect the integrity of Assam. Both episodes showed that Assam’s existence could not be taken for granted and that its leaders had to be vigilant in the new constitutional arrangements. For exams, the key facts are the date of the Mountbatten Plan (3 June 1947), the two countries created (India and Pakistan), the two provinces partitioned (Bengal and Punjab), the district that decided by referendum (Sylhet), the date of the referendum (6 July 1947), the result (majority voted for Pakistan/East Bengal), and the effects on Assam’s area, population and the proportion of Assamese speakers. A favourite trap is to say that the referendum was held before the Mountbatten Plan, or that Sylhet stayed with India; both are wrong.

Why the Sylhet Referendum Matters for Exams
This topic is a must for Assam exams because it explains how Assam lost territory during partition. Examiners ask the date of the Mountbatten Plan (3 June 1947), the two new countries (India and Pakistan), the partitioned provinces (Bengal and Punjab), the district that held a referendum (Sylhet), the date of the referendum (6 July 1947), the result (majority for Pakistan), and the effects on Assam — smaller area, smaller population, but a higher proportion of Assamese speakers. The hill districts that stayed with India are also frequently asked. A common trap is to place the referendum before the Mountbatten Plan; in fact the referendum was held after the plan, in July 1947. The topic is closely linked with the grouping issue, and together they explain the determination of Assam’s leaders to defend the state’s integrity.
How to Prepare the Sylhet Referendum
- Fix the plan. The Mountbatten Plan was announced on 3 June 1947; British India was partitioned into India and Pakistan.
- Fix the provinces. Bengal and Punjab were the two provinces partitioned.
- Fix Sylhet. Sylhet was a Muslim-majority district of Assam that decided its fate by referendum on 6 July 1947.
- Remember the result. The majority voted to join East Bengal/Pakistan; Sylhet was detached from Assam and merged with East Bengal in 1947.
- Note the effects. Assam’s area and population decreased, the proportion of Assamese speakers increased, and the hill districts stayed with India.
Common Exam Traps
- The Mountbatten Plan was announced on 3 June 1947, not in 1946.
- The Sylhet Referendum was held after the plan, on 6 July 1947.
- Sylhet was a Muslim-majority district and joined Pakistan; it did not stay with India.
- The loss of Sylhet decreased Assam’s area and population but increased the proportion of Assamese speakers.
- The hill districts (Khasi, Jaintia, Garo, Lushai/Mizo, Naga) remained with India.
