History of Assembly Constituencies in Bihar State
The history of Assembly constituencies in Bihar is deeply intertwined with the region’s political evolution, from its formation as a separate province to its current democratic structure. Before 1936, Bihar was part of the Bihar and Orissa Province. The Government of India Act of 1935 paved the way for a bicameral legislature, establishing a Legislative Assembly (lower house) and a Legislative Council (upper house) for Bihar upon its separation from Orissa in 1936. The initial constituencies were drawn based on a limited franchise, primarily property owners and educated individuals.
Post-independence, with the adoption of the Indian Constitution in 1950, universal adult suffrage was introduced, dramatically reshaping the electoral landscape. The first general elections in 1952 created more broadly defined constituencies. Subsequent Delimitation of Bihar assembly constituencies exercises, notably after the 1961, 1971, and 2001 censuses, have continuously redefined the boundaries of these seats to ensure proportional representation based on population changes. These exercises have also adjusted the number and allocation of Reserved assembly constituencies in Bihar (SC/ST) to reflect demographic shifts and uphold constitutional provisions for social justice.
The most recent delimitation, implemented before the 2010 assembly elections, fixed the current count of 243 Assembly constituencies in the state of Bihar. This process involved meticulous adjustments to ensure each constituency represented roughly an equal population while maintaining administrative contiguity. Over the decades, these constituencies have witnessed the rise and fall of various political parties and leaders, reflecting the dynamic nature of Bihar’s political tapestry and the evolving aspirations of its diverse electorate.

In 2015, the seat was captured by RJD, reflecting a competitive landscape in which control alternated between JD-U and RJD over the past two elections. This recurring shift underscores Chiraia’s status as a swing constituency, where local leadership, caste alliances, and development delivery play a decisive role in shaping results.
The constituency’s population includes Yadav, Kurmi, Brahmin, Muslim, and Dalit groups, with OBC communities forming the majority vote share. Key issues include flood management, poor road infrastructure, irrigation facilities, and access to healthcare and education. As the following election approaches, voter sentiment in Chiraia is expected to hinge on developmental progress and local representation, making it one of the most closely watched contests in East Champaran.

In the 2020 Bihar Assembly election, Faisal Rahman (INC) won the seat with 1,01,161 votes, defeating Pawan Jaiswal (Independent) by a margin of 13,211 votes.

The constituency’s voting pattern often reflects a combination of community ties, candidate credibility, and local outreach rather than evident partisan loyalty.
The demographic profile includes Yadav, Muslim, Bhumihar, and Dalit populations, with backward castes and minorities forming significant vote blocs. Key local issues include poor road conditions, healthcare facilities, recurring flood damage, and unemployment. As the upcoming election approaches, Dhaka’s political contest is expected to remain fluid, with personal influence and local development performance playing a decisive role in shaping voter preferences.

The narrow margins in consecutive elections reflect Sheohar’s highly competitive, closely contested political landscape.
The constituency’s social composition includes Paswan, Ravidas, and other Scheduled Caste groups, as well as Yadavs, Muslims, and EBC communities, all of which influence outcomes. Key local issues include flood control, road infrastructure, education facilities, rural employment, and access to healthcare. As the following election approaches, voter sentiment in Sheohar is expected to hinge on youth employment and development performance, with both RJD and JD-U preparing for another tight contest in this politically sensitive SC-reserved constituency.

The constituency includes Riga, Bairgania, and parts of Parihar and Sursand blocks, characterised by fertile plains, sugarcane fields, and a largely rural population. The area lies near the Indo-Nepal border and depends heavily on agriculture, small-scale trade, and migrant remittances. As per the 2020 electoral roll, Riga had around 3.02 lakh electors, with a voter turnout of approximately 62%.
In the 2020 Bihar Assembly election, Aman Bhushan Hajari (JD-U) secured victory with 87,875 votes, defeating Awdhesh Kumar Rai (INC) by a margin of 19,671 votes. In 2015, the seat was held by Awdhesh Kumar Rai (INC), indicating a pattern of alternating political preferences between JD (U) and Congress. The contests in Riga have generally been close, with voting behaviour influenced by caste alignment and local leadership rather than national-level political trends.
The constituency’s demography is dominated by Yadav, Kurmi, Brahmin, Muslim, and Dalit communities, with OBCs forming a decisive share. Key issues include poor road and drainage infrastructure, recurring floods, lack of irrigation facilities, and unemployment. As the following election approaches, voter sentiment in Riga is expected to focus on local development and flood management, with JD-U seeking to consolidate its recent gains. At the same time, opposition parties aim to unify backwards and minority votes to regain lost ground.
Bathnaha (SC) (24)
Bathnaha (Constituency No. 24) is a Scheduled Caste (SC) reserved seat of the Bihar Legislative Assembly located in Sitamarhi district, and it falls under the Sitamarhi Lok Sabha constituency. The constituency covers Bathnaha, Majorganj, and parts of Parihar and Sursand blocks, lying along the Indo-Nepal border. The region is predominantly rural, with agriculture as the primary livelihood, supported by sugarcane, maize, and paddy cultivation. Seasonal migration and small-scale trading also contribute to the local economy. As per the 2020 electoral roll, Bathnaha had around 2.84 lakh electors, with voter turnout close to 63%.
In the 2020 Bihar Assembly election, Manju Devi (JD-U) won the seat with 81,335 votes, defeating Abdul Sattar (RJD) by a margin of 22,312 votes. In the 2015 election, RJD had secured the seat, showing alternating trends between JD-U and RJD, typical of the district’s competitive politics. Over recent years, JD-U has strengthened its grassroots network here through welfare schemes and local outreach, consolidating its position among Scheduled Caste voters.
The constituency’s social fabric includes Paswan, Ravidas, and other Scheduled Caste communities, as well as EBC and Muslim populations. Key local concerns include flood control, embankment maintenance, poor road infrastructure, education, and health services. As the upcoming election approaches, Bathnaha’s voter sentiment is expected to focus on flood resilience and welfare delivery. JD-U holds an organisational edge but faces challenges from opposition efforts to mobilise caste and community-based alliances.
Parihar (25)
Parihar (Constituency No. 25) is a General seat of the Bihar Legislative Assembly located in Sitamarhi district, and it forms part of the Sitamarhi Lok Sabha constituency. The constituency comprises Parihar, Sursand, and parts of Bairgania and Bathnaha blocks, situated along the Indo-Nepal border. It is a predominantly rural area characterised by fertile land, sugarcane and paddy fields, and frequent flooding from the Bagmati River. Agriculture is the main economic activity, supplemented by small trade and migration-based earnings. As per the 2020 electoral roll, Parihar had around 2.97 lakh electors, with voter turnout close to 62%.
In the 2020 Bihar Assembly election, Gayatri Devi (BJP) won the seat with 95,361 votes, defeating RJD’s Ram Naresh Prasad Yadav by a margin of 22,056 votes. In 2015, the seat was won by Ram Naresh Prasad Yadav (RJD), highlighting a pattern of alternating representation between BJP and RJD. The constituency has witnessed close contests, reflecting a balance between caste dynamics and development-oriented voting behaviour.
Parihar’s social composition includes Yadavs, Brahmins, Muslims, and Dalit groups, with OBC voters playing a decisive role. Major local issues include flood protection, road connectivity, irrigation, and rural employment. As the next election nears, voter sentiment in Parihar is expected to focus on the government’s handling of flood management and development delivery. The BJP aims to retain its foothold, while the RJD seeks to rebuild its earlier support base through local alliances.
Sursand (26)
Sursand (Constituency No. 26) is a General seat of the Bihar Legislative Assembly located in Sitamarhi district, under the Sitamarhi Lok Sabha constituency. The constituency covers Sursand, Parihar, and adjoining parts of Bairgania and Bathnaha blocks, lying along the Indo-Nepal border. The area is predominantly rural, with fertile alluvial soil supporting the cultivation of paddy, wheat, and sugarcane. Flooding from rivers such as the Bagmati and Lakhandei frequently affects local livelihoods. As per the 2020 electoral roll, Sursand had around 2.93 lakh electors, with a voter turnout of approximately 61%.
In the 2020 Bihar Assembly election, Syed Abu Dojana (RJD) won the seat with 90,347 votes, defeating Dr. Ashok Kumar (JD-U) by a margin of 13,287 votes. In 2015, the seat was also held by Syed Abu Dojana (RJD), reflecting the party’s consistent strength and the MLA’s strong local presence. RJD’s success in Sursand is often attributed to its consolidated Muslim-Yadav support base and the personal influence of its sitting representative.
The constituency’s demography includes significant populations of Yadavs, Muslims, Kurmis, and Dalits, with OBC and minority communities shaping electoral outcomes. Key local issues include annual flooding, poor road and drainage infrastructure, limited healthcare facilities, and unemployment. As the upcoming election approaches, voter sentiment in Sursand seems to be driven by the demand for improved flood control and rural development. RJD currently enjoys an incumbency advantage but faces expectations for tangible progress in infrastructure and livelihood creation.
Bajpatti (27)
Bajpatti (Constituency No. 27) is a General seat of the Bihar Legislative Assembly located in Sitamarhi district, and it falls under the Sitamarhi Lok Sabha constituency. The constituency comprises Bajpatti, Parihar, and parts of Dumra and Pupri blocks, covering a region of fertile agricultural plains intersected by seasonal rivers such as the Bagmati. The area is predominantly rural, with farming—particularly paddy, maize, and sugarcane cultivation—forming the backbone of the local economy. Seasonal migration to urban centres for employment is also common. As per the 2020 electoral roll, Bajpatti had around 3.01 lakh electors, with a voter turnout of approximately 62%.
In the 2020 Bihar Assembly election, Mukesh Kumar Yadav (RJD) won the seat with 92,648 votes, defeating Renu Kumari (BJP) by a margin of 22,583 votes. In 2015, the seat was also held by RJD, showing a pattern of continued party dominance over multiple election cycles. The RJD’s strong performance here is driven by its consolidated Yadav and Muslim support base, supplemented by alliances with EBC and Dalit groups.
Bajpatti’s demography includes Yadav, Muslim, Brahmin, and Dalit populations, with OBCs holding a decisive majority. The major local issues include flood management, poor road infrastructure, agricultural support, and a lack of employment opportunities. As the upcoming election approaches, RJD’s incumbency advantage may continue if its development and welfare outreach remain effective. However, the BJP is expected to challenge through targeted campaigns focused on governance and connectivity improvements.
Sitamarhi (28)
Sitamarhi (Constituency No. 28) is a General seat of the Bihar Legislative Assembly located in Sitamarhi district, forming part of the Sitamarhi Lok Sabha constituency. The constituency is centred around Sitamarhi town, the district headquarters, and includes adjoining rural areas of Dumra and Belsand blocks. Sitamarhi holds religious and historical significance as the believed birthplace of Goddess Sita, making it an essential cultural centre in North Bihar. The local economy is driven by trade, services, small industries, and agriculture, particularly paddy and sugarcane cultivation. As per the 2020 electoral roll, Sitamarhi had around 3.17 lakh electors, with a voter turnout close to 60%.
In the 2020 Bihar Assembly election, Sunil Kumar (BJP) won the seat with 96,157 votes, defeating RJD’s Abdul Ghafoor by a margin of 18,274 votes. In 2015, the seat was held by RJD, reflecting Sitamarhi’s tendency toward closely fought contests and shifting political loyalties between RJD and BJP. Over the past decade, the constituency has shown a balanced electoral pattern, influenced by both developmental issues and caste coalitions.
Sitamarhi’s demography comprises Yadav, Brahmin, Bhumihar, Muslim, and Dalit communities, with urban voters playing an increasingly significant role. Key concerns include urban infrastructure, drainage, flood control, employment, and healthcare. As the following election approaches, voter sentiment in Sitamarhi is expected to focus on civic amenities and economic development, with the BJP’s incumbent advantage tempered by rising opposition efforts to mobilise rural and minority voters.
Runnisaidpur (29)
Runnisaidpur (Constituency No. 29) is a General seat of the Bihar Legislative Assembly located in Sitamarhi district, and it forms part of the Sheohar Lok Sabha constituency. The constituency covers Runnisaidpur, Parsauni, and parts of Belsand and Dumra blocks, representing a predominantly rural region characterised by fertile Gangetic plains and a high dependence on agriculture. Paddy, wheat, and sugarcane are the main crops, and migration to other states for labour is common. As per the 2020 electoral roll, Runnisaidpur had around 3.03 lakh electors, with a voter turnout of approximately 63%.
In the 2020 Bihar Assembly election, Gautam Kumar (RJD) won the seat with 96,878 votes, defeating Chandreshwar Prasad Chandravanshi (BJP) by a margin of 16,685 votes. In 2015, the seat was also held by RJD, showing consistent support for the party in recent years. The RJD’s dominance here is attributed to a stable alliance of Yadav and Muslim voters, along with support from sections of Dalits and EBCs.
Runnisaidpur’s social composition includes Yadavs, Kurmis, Brahmins, Muslims, and Scheduled Castes. Major local issues include flood control, rural road connectivity, irrigation, education, and employment opportunities. As the upcoming election approaches, voter sentiment is likely to hinge on the effectiveness of local governance and agricultural support schemes. RJD aims to maintain its stronghold, while BJP seeks to make inroads by focusing on infrastructure and welfare delivery.
Belsand (30)
Belsand (Constituency No. 30) is a General seat of the Bihar Legislative Assembly situated in Sitamarhi district, and it falls under the Sheohar Lok Sabha constituency. The constituency comprises Belsand, Parsauni, and parts of Runnisaidpur and Dumra blocks, encompassing a mix of rural villages and small market centres. Located within the flood-prone Gandak basin, Belsand’s economy is largely agricultural, relying on paddy, maize, and sugarcane cultivation, along with income from migrant labour. As per the 2020 electoral roll, Belsand had around 2.96 lakh electors, with voter turnout close to 62%.
In the 2020 Bihar Assembly election, Surendra Ram (RJD) won the seat with 92,784 votes, defeating Shashi Bhushan Choudhary (BJP) by a margin of 16,835 votes. In 2015, the seat was also captured by RJD, signalling consistent support for the party across two consecutive elections. The RJD’s strength in Belsand is largely anchored in its Yadav-Muslim vote base, supplemented by EBC and Dalit backing.
The constituency’s demography includes Yadav, Muslim, Brahmin, and Scheduled Caste groups. Key issues influencing voter sentiment include flood management, poor road infrastructure, healthcare access, and job opportunities. As the 2025 election approaches, RJD enters with an incumbency advantage but faces the challenge of translating political loyalty into visible development, while BJP and JD-U aim to capitalise on dissatisfaction regarding basic infrastructure and employment generation.
Sitamarhi
Harlakhi, constituency number 31 in Madhubani district, falls under the Madhubani Lok Sabha seat and is an unreserved general category assembly segment. It encompasses over 290,000 electors as recorded in the 2020 rolls, predominantly rural areas including the Harlakhi and Madhwapur community development blocks, as well as gram panchayats like Karhara and Teoth in the Benipatti block.
These areas are dotted with fertile farmlands along the Kosi river tributaries, which often lead to seasonal flooding. In the 2020 elections, Janata Dal (United)’s Sudhanshu Shekhar clinched victory with 60,393 votes, defeating Communist Party of India’s Ram Naresh Pandey by a margin of 17,593 votes in a contest that saw a 57.52% turnout from 167,300 voters.
This was built on a tighter 2015 race where Rashtriya Lok Samta Party’s Basant Kumar edged out Congress’s Muhammad Shabbir by just 3,892 votes, reflecting the seat’s history of shifting alliances among NDA partners amid left-wing challenges. Socially, Yadavs form a key OBC bloc alongside significant Muslim and Scheduled Caste populations, comprising around 11%. EBCs and upper castes like Brahmins and Rajputs influence outcomes in this agrarian belt, reliant on paddy and maize cultivation. However, high out-migration to urban centres for labour underscores economic pressures.
Persistent floods devastate crops and homes annually, fuelling demands for better embankments, irrigation, and rural jobs, while education and health access lag; recent initiatives include a Rs 31 crore tourism push at Phulhar Sthan shrine and broader Madhubani road-water projects worth over Rs 650 crore. As 2025 approaches, JD(U)’s consolidation among OBCs and EBCs signals NDA edge, yet rising flood distress could amplify opposition appeals on relief and employment.
Benipatti (32)
Benipatti, constituency number 32 in Madhubani district, aligns with the Madhubani Lok Sabha seat and operates as an unreserved general category assembly segment. It draws from approximately 284,597 electors based on the 2020 rolls, spanning a largely rural landscape that includes the Kaluahi community development block alongside key gram panchayats in Benipatti block, such as Bishunpur, Basaitha, Behata, Pali, and Meghben, where fertile alluvial plains fed by Kosi river tributaries support paddy fields but expose villages to recurrent flooding. In the 2020 polls.
Bharatiya Janata Party’s Vinod Narayan Jha triumphed with 78,862 votes, outpacing Indian National Congress’s Bhawana Jha’s 46,210 by a decisive 32,652-vote margin amid 54.73% turnout, reversing her 2015 victory where she had edged him by 4,734 votes on 41.52% share in a closer Mahagathbandhan sweep. This swing highlights the BJP’s consolidation in a seat with historical Brahmin voter dominance, often yielding.
Brahmin MLAs have been part of the party since its 1951 formation, though alliances have varied, with Congress and JD(U) holding in prior decades. Demographically, Brahmins anchor upper-caste influence alongside substantial Yadav and other OBC clusters, EBCs, 12% Scheduled Castes, and a modest Muslim presence, fuelling caste-driven mobilisations in this agrarian economy marked by crop cultivation and high seasonal migration to cities for labour.
Persistent challenges include annual Kosi floods eroding livelihoods, inadequate embankments, rural unemployment, and limited access to quality education and healthcare. Meanwhile, recent Rs 650 crore district-wide initiatives under Chief Minister Nitish Kumar—encompassing roads, bridges, and irrigation—target resilience alongside agricultural support like cattle schemes. With the 2025 elections underway, the BJP’s Brahmin and upper-caste hold suggests NDA continuity, yet flood recovery lapses and migration woes may bolster opposition outreach to OBCs and EBCs for a tighter fray.
Khajauli (33)
Khajauli, constituency number 33 in Madhubani district, is part of the Jhanjharpur Lok Sabha seat and serves as an unreserved general category assembly segment. It covers about 317,000 electors as per the 2020 rolls, embracing a rural expanse of Jainagar and Basopatti community development blocks, plus gram panchayats like Nararh East, Mahua Ekdara, Datwar, Sarabe, Rasidpur, Betakakarghati, and Khajauli in the Khajauli block, where alluvial soils along Kosi river tributaries sustain farming but invite frequent floods.
The 2020 elections saw Bharatiya Janata Party’s Arun Shankar Prasad secure 83,161 votes for a 44.51% share, defeating Rashtriya Janata Dal’s Sitaram Yadav by 22,689 votes at 61.11% turnout, marking a BJP flip from Yadav’s 2015 win on 71,534 votes with a slim 10,703-vote edge over Prasad amid Mahagathbandhan’s sweep. This reversal highlights NDA’s rising traction in a seat prone to alliance-driven swings rather than outright dominance.
Socially, Yadavs lead OBC influence alongside 16.7% Scheduled Castes, EBCs, and upper castes like Brahmins. The economy is centred on paddy, maize, and makhana cultivation, offset by heavy out-migration for urban jobs and low literacy at 58.62%. Flood devastation, youth unemployment, poor roads, and healthcare gaps dominate concerns.
Recent Rs 500 crore-plus district initiatives on embankments, irrigation canals, and rural electrification under Jal Jeevan Hariyali aim to build resilience. As the November 2025 polls near, the BJP’s OBC consolidation points to NDA retention. However, opposition focus on migration relief and caste census could stir EBC and Yadav shifts for a keenly watched battle.
Babubarhi (34)
Babubarhi, constituency number 34 in Madhubani district, is part of the Jhanjharpur Lok Sabha seat as an unreserved general category assembly segment. It accounts for roughly 310,000 electors from the 2020 rolls, covering a predominantly rural terrain under the Babubarhi community development block with villages such as Bagaul, Bairia, Balirajpur, and Sugauna, where fertile plains nourished by Kosi river tributaries yield paddy and vegetables yet suffer annual inundations.
The 2020 elections delivered a win for Janata Dal (United)’s Mina Kumari with 77,367 votes at 41.5% share, prevailing over Rashtriya Janata Dal’s Umakant Yadav’s 65,879 by a 11,488-vote margin amid 60% turnout, extending JD(U)’s grip from Kapil Deo Kamat’s 2015 triumph on 61,486 votes against Lok Janshakti Party’s Binod Kumar Singh by 20,267. However, alliance realignments have kept contests fluid without entrenched dominance.
Demographically, Yadavs and Kushwahas anchor OBC sway alongside Rajputs and Brahmins among upper castes, 12.6% Scheduled Castes, and 11% Muslims. The economy is farming-dependent and plagued by seasonal labour migration to Delhi and Punjab, with literacy hovering below 60%. Floods ravage crops and displace families yearly, alongside unemployment and patchy rural infrastructure, spurring calls for robust embankments; notable strides include Chief Minister Nitish Kumar’s Rs 8,911 crore initiatives in Madhubani for the Western Kosi Canal and Rs 650 crore on roads and electrification. Heading into the November 2025 polls, JD(U)’s OBC consolidation hints at NDA continuity, but escalating flood impacts and migration strains may energise RJD’s outreach to vulnerable groups for a polarised showdown.
Bisfi (35)
Bisfi, constituency number 35 in Madhubani district, contributes to the Madhubani Lok Sabha seat and functions as an unreserved general category assembly segment. It accounts for roughly 328,000 electors as per the 2020 rolls, spanning a rural patchwork of the Bisfi community development block alongside gram panchayats such as Satlakha, Rahika, Saurath, Najirpur, Jagatpur, Kakraul North and South, Malangia, Basauli, Sapta, Ijra, and Hasanpur from Rahika block, where alluvial farmlands yield paddy and vegetables under the shadow of the Kosi river systems.
The 2020 elections delivered a Bharatiya Janata Party victory for Haribhushan Thakur with 86,787 votes at 48.43% share, edging out Rashtriya Janata Dal’s Faiyaz Ahmad’s 76,505 by 10,282 votes amid 54.61% turnout, flipping the seat from Ahmad’s 2015 RJD win where he claimed 70,975 votes and a commanding 35,325-vote lead over Rashtriya Lok Samata Party’s Manoj Kumar Yadav in a Mahagathbandhan rout at 52.69% polling.
This shift underscores BJP’s inroads against RJD’s traditional hold in multi-cornered contests shaped by alliances. Demographically, Muslims at 30% form the largest bloc, complemented by influential Dalits, Brahmins, Yadavs, and Bhumihars in an agrarian economy with low literacy around 58% and widespread seasonal migration for urban labour. Voter priorities include persistent floods alongside rural road dilapidation that hampers produce transport, inadequate schooling infrastructure, and youth job scarcity, though Madhubani’s recent Rs 13,480 crore push under national schemes covers housing, rail links, electrification, and Rs 650 crore district initiatives for bridges and connectivity.
As the November 2025 polls loom, the BJP’s upper-caste and partial Muslim outreach signals NDA resilience, yet RJD’s caste census advocacy may rally OBCs and minorities for a polarised rematch.
