Mangaldai is a general (unreserved) constituency and one of the 11 segments of the Darrang-Udalguri Lok Sabha constituency. Mangaldai town is the administrative headquarters of Darrang district and serves as the urban core of the constituency. The Mangaldai assembly constituency includes the town along with a large number of surrounding villages, giving it a predominantly rural character. Before the 2023 Assam delimitation exercise, the constituency was known as Mangaldoi, a Scheduled Caste-reserved seat. The boundaries of the constituency were also adjusted during the delimitation, although the core areas remained largely unchanged.
Established in 1951, Mangaldai has seen contests in 15 assembly elections so far. If numbers are to be considered, Congress has been the dominant party in the constituency for most of its history, winning nine out of the 15 elections. On closer inspection, however, an interesting pattern emerges. After winning three consecutive elections in 1952, 1957, and 1962, Congress has never won consecutive assembly elections in the constituency since. No party, in fact, after 1962 has been able to achieve consecutive wins in Mangaldai. An independent won the seat in 1967, in the following election in 1972 Congress was able to recapture the seat, but then lost it again in 1978 to the Janata Party. The trend then continued with winners alternating between Congress and others, with another independent candidate winning in 1985, Asom Gana Parishad (AGP) winning two elections in 1996 and 2006, and the BJP winning in 2016. Congress won the seat again in the most recent election in 2021, thereby continuing the anti-incumbency pattern. Overall, besides nine victories of the Congress party, Independents and the AGP have won the Mangaldai seat twice each, while the Janata Party and the BJP have each held it once.
In 2011, the Congress candidate Basanta Das defeated the AIUDF candidate Mahendra Das by a margin of 23,723 votes, with the AGP placed third and the BJP fourth. In 2016, however, Gurujyoti Das of the BJP won the seat, defeating the sitting MLA Basanta Das of Congress by a margin of 21,856 votes. In 2021, Basanta Das of Congress won the seat back, defeating Gurujyoti Das of the BJP by a margin of 24,354 votes. Basanta Das received 111,386 votes while Gurujyoti Das polled 87,032 votes out of a total of 2,02,144 valid votes polled that year.
The voting pattern in the previous Mangaldoi (SC) and the current Mangaldai assembly segment during the Lok Sabha elections reflects shifts along community lines. Before 2023, the Darrang-Udalguri Lok Sabha constituency was known as the Mangaldoi Lok Sabha constituency. In the 2009 Lok Sabha elections, AIUDF led the BJP by a small margin of 2,632 votes, with Congress not far behind. In the 2014 parliamentary elections, however, the sequence flipped with Congress leading against the BJP by a margin of 22,444 votes, with the AIUDF this time being a distant third. In 2019, Congress led again against the BJP by a margin of 22,879 votes. And most recently, in 2024, the lead flipped, and the BJP led against Congress by a margin of 37,925 votes.
Mangaldai constituency had 201,732 eligible voters on its final roll for the 2026 assembly elections, witnessing a small rise from 198,086 registered voters in 2024. Before delimitation in 2023, the number of registered voters in the Mangaldoi (SC) assembly constituency in 2021 stood at 237,615. Earlier figures stood at 222,756 in 2019, 200,056 in 2016, 187,042 in 2014 and 186,789 in 2011.
The voter turnout has remained very high at 77.28 per cent in 2011, 85.6 per cent in 2014, 88.73 per cent in 2016, 86.55 per cent in 2019, 85.71 per cent in 2021 and 84.43 per cent in 2024.
Demographics, based on available data largely from the 2011 Census proportions adjusted for the area and delimitation changes, indicate a notable Muslim presence of over 45 per cent, along with a Hindu majority, Scheduled Castes and smaller Scheduled Tribes. The constituency features a mix of Assamese and Bengali-speaking communities along with agrarian groups, contributing to its rural character.
Mangaldai has a rich historical and cultural legacy as one of the oldest towns in Assam, named after Princess Mangaldahi, daughter of the Raja of Darrang, who was married to the Ahom king Pratap Singha in the early 17th century to forge political alliances between the Koch and Ahom kingdoms. The constituency is also closely tied to the historic Patharughat peasant uprising of 1894, often called Assam’s Jallianwala Bagh, where British forces opened fire on protesting farmers. The Shaheed Minar memorial stands about 16 km from Mangaldai town to commemorate the event. The area features ancient Vaishnavite satras (monasteries) like Khatara Satra (one of the oldest, founded in 1568) and a strong presence of tea garden communities with vibrant Assamese and Adivasi traditions. Nearby attractions include the Orang National Park, known for its high density of one-horned rhinos, tigers, and elephants, and Barnadi Wildlife Sanctuary, famous for the rare pygmy hog, making the region a quiet hub for eco-tourism amid its riverine plains and flood-prone beels.
The Mangaldai constituency covers parts of Darrang district in central Assam with flat alluvial plains along the southern bank of the Brahmaputra River, interspersed with wetlands, beels (lakes), and gentle undulations in the south towards the Meghalaya plateau foothills. The terrain supports paddy farming, fishing in wetlands, and some horticulture, but is prone to seasonal flooding from the Brahmaputra and its tributaries like the Barnadi and Nanoi rivers. Livelihoods in Mangaldai depend mainly on paddy cultivation, fishing, small trade and agriculture-related activities. Fertile alluvial soils and abundant rainfall sustain these activities. Infrastructure includes road connectivity via National Highway 15, which passes through Mangaldai town, along with several state highways linking to nearby areas. Rail access is available at Rangiya Railway Station, about 25-30 km to the west. Basic amenities include ongoing developments in rural roads, irrigation, and local markets.
Nearby towns include Sipajhar to the west, about 15 km away, Rangiya to the southwest, about 25-30 km away, and Tezpur to the east, about 95-100 km away. The state capital, Dispur/Guwahati, lies around 70-80 km west. The constituency lies close to the Meghalaya border to its south.
Mangaldai is poised to witness a close and intriguing contest. If the Congress party won the 2021 Assembly elections, the BJP led in 2024 by a comfortable margin. The BJP has fielded Nilima Devi as its candidate, while the Congress party has named Rijumoni Talukdar. Taking on these women candidates are the AIUDF candidate Azizur Rahman, Ajit Acharjya of the Socialist Unity Centre of India (Communist), Harekrishna Deka of the Trinamool Congress and Prabin Kumar Deka, an Independent. The main contest, however, is expected to be between the BJP and the Congress party, with the BJP enjoying a marginal edge in an election that promises to go to the wire.
