border to 1951 Tarai as frontier and homeland The Nepal Tarai was never merely an empty frontier awaiting settlement from the hills. Forests, grasslands, wetlands, farms, market towns, pilgrimage centres, estates, and older settlements linked the Himalayan foothills to the Gangetic plain. Its history therefore has to begin with inhabited landscapes and competing claims, not with the administrative language of reclamation. State revenue, timber extraction, disease environments, transport, and cross-border trade changed the density and distribution of settlement over time. These processes affected long-established Tharu and other communities as well as Maithili-, Bhojpuri-, Awadhi-, Urdu-, and Nepali-speaking migrants and townspeople. “Tarai” names a changing ecological and administrative zone, not one timeless social population (Gaige 1975; Whelpton 2005). “Tarai” as an ecological and administrative category The word Tarai could describe lowland terrain, a revenue region, a forest belt, or a frontier of particular districts depending on date and document. Such usages overlap but are not identical. A nineteenth-century treaty clause, a Rana revenue order, a census table, and a modern provincial map therefore cannot be treated as interchangeable maps of the same space. This distinction also prevents the cultural geography of Mithila from being equated mechanically with every administrative tract of the Nepalese plains. Maithili cultural and linguistic networks were especially important in the eastern and central Tarai, while the wider Tarai also contained many other language and social fields. Border before border Before the nineteenth-century treaty regime, routes, political influence, forests, estates, pilgrimage, and kinship crossed what later became an international frontier. The modern India–Nepal boundary is therefore indispensable for colonial and contemporary history but anachronistic when projected unchanged into the Karnata, Oiniwar, or early Shah periods. The frontier became progressively more consequential as treaties, surveys, customs posts, courts, land records, and police practices attached different legal effects to each side. Social crossing and formal sovereignty should be reconstructed together rather than forced into a choice between a “real” border and an “imaginary” one. The Anglo-Nepalese War and the Treaty of Sugauli The Treaty of Sugauli was signed on 2 December 1815 after the Anglo-Nepalese War. The Nepalese counterpart was received and the British counterpart delivered on 4 March 1816. The treaty is a primary legal anchor for the new interstate relationship, but it did not by itself freeze every sector of the present boundary (Treaty of Sugauli, arts. I–IX; Aitchison 1909). Article III described territorial cessions through rivers and lowlands, including the tract between the Gandak and the Kosi/Coosah in which British authority had been introduced or was being introduced. This language is historically important because it shows a frontier formulated through rivers, administrative possession, and negotiated geography rather than through a modern coordinate list. Article III and river-defined cessions Sugauli’s cession clauses used the Kali, Rapti, Gandak, Kosi/Coosah, Mechi and Teesta as reference lines for large territorial descriptions. Rivers could make legal wording appear precise while their channels, tributary identifications and floodplain settings could complicate implementation on the ground. For the Mithila–Tarai borderland, the central lesson is methodological: a treaty line must be read with subsequent surveys, local disputes, supplementary agreements, and the geomorphic history of the named rivers. The legal text is authoritative for the claim it made, not a guarantee that every locality was immediately uncontested. Ratification and implementation in March 1816 The surviving treaty text records the exchange at Makwanpur on 4 March 1816. This date is more precise than the common shorthand “Treaty of 1816,” because the instrument itself was dated December 1815 while the exchange that brought the settlement into effect occurred in March 1816. Implementation required evacuation, administrative takeover, and boundary work. The post-war frontier was therefore a process of making sovereignty legible through officials and territorial practice, not simply a line appearing fully formed at the moment of signature. The December 1816 supplementary Tarai restoration A memorandum presented on 8 December 1816 proposed restoring substantial Tarai lands between the Kosi/Coosah and Gandak and between the Gandak and Rapti. Nepalese acceptance followed in December. This supplementary settlement is indispensable: the post-Sugauli border cannot be reconstructed accurately from Article III alone (Supplementary Memorandum, 8 December 1816; Aitchison 1909). The restoration also replaced part of the pension arrangement contemplated after the territorial cessions. Its legal and fiscal logic shows how frontier settlement was intertwined with compensation, revenue, and the practical burden of administration. Tirhut and Saran in the 1816 supplementary text The December memorandum expressly excepted disputed lands in the districts of Tirhut and Saran from automatic restoration. It also referred to an earlier 1812 settlement as a basis for handling long-running Tirhut claims. This is unusually direct primary-text evidence that the border-making process touched the historical field of this book rather than only distant Himalayan sectors. Because the text itself labels lands disputed, a modern historian should not convert the 1816 restoration into a clean territorial polygon. The correct reconstruction contains zones requiring investigation and settlement by officials on both sides. Boundary commissioners, exchanges, and the “straight line” problem The supplementary terms envisaged commissioners investigating the frontier and allowed exchanges where existing grants or ownership claims would otherwise create administrative difficulty. The problem was not only geopolitical; it involved particular landholders whose property could fall inconveniently across the new sovereign line. This is a reminder that boundary history is also property history. Survey, ownership, cultivation, river change, and jurisdiction could produce different answers to the question “where is the border?” until documentary and field settlements aligned them. Rivers as legal boundaries in moving floodplains North Bihar and the adjoining Tarai are alluvial landscapes in which channels migrate and avulse. A treaty that uses a river as a boundary therefore requires a dated understanding of which channel, bank, or confluence was intended. Later maps may preserve legal memory, geomorphic change, or both. The book’s earlier river-history method applies here directly: hydrological change is not a device for dismissing treaties, but a reason to interpret their spatial clauses with dated surveys and local records rather than with present-day channels alone. The 1860 Naya Muluk restoration A second major territorial adjustment followed Nepalese assistance to the British during the uprising of 1857. The 1860 settlement restored the western Tarai tracts conventionally identified with present Banke, Bardiya, Kailali and Kanchanpur, remembered in Nepal as the Naya Muluk or “new country.” The restoration confirms again that Nepal’s present southern boundary is a cumulative treaty history. Sugauli was foundational, the December 1816 settlement revised its Tarai consequences, and the 1860 adjustment altered the western lowlands once more.

The 1860 territorial restoration was explicitly connected in treaty tradition with that assistance. Nepal remained outside British India, yet Rana foreign policy operated within a powerful asymmetrical relationship with the Raj. This combination—formal sovereignty and strategic dependence—helps explain why neither “colony” nor “fully detached isolation” adequately describes Rana-era Nepal. The Tarai, adjoining British districts, and military routes made the relationship materially visible. Rana oligarchy after 1846 After the political upheaval of 1846, hereditary Rana prime ministers dominated the machinery of government while the Shah monarchy continued. The regime centralized high office and political succession within the Rana family, though its administrative reach remained uneven across districts and local societies (Whelpton 2005). In the Tarai, state presence worked through revenue offices, land assignments, police and military authority, judicial institutions, contractors, merchants, local landholders, and transport corridors. “Rana rule” therefore describes a regime whose practical effects varied greatly by place and social position. Shah monarchy under Rana prime ministers The continued Shah kingship under Rana prime-ministerial dominance matters for constitutional language. Nepal was not formally converted into a republic or a British protectorate; instead, royal sovereignty coexisted with a hereditary oligarchy that controlled executive power. Later democratic narratives understandably describe 1951 as the fall of Rana autocracy, but the institutional transition should not be simplified into the birth of the Nepalese state. The state, monarchy, courts, army and revenue systems all predated 1951 and were reorganized rather than created from nothing. The Mulukī Ain of 1854 and legal centralization The Mulukī Ain of 1854, formulated under Jang Bahadur Rana, was an ambitious national legal code covering state and court organization, criminal and private law, property, family relations, caste and purity rules, customary law, labour and procedure. It is one of the strongest primary-source windows into Rana-era legal ordering (Khatiwoda, Cubelic, and Michaels 2021). The code’s aspiration to standardize law across the kingdom should not be confused with uniform enforcement. Surviving legal records show that institutions, petitioning, local practice and later revisions mediated how provisions were applied. Caste hierarchy: code is not census The Mulukī Ain organized legal consequences through ranked caste-status categories and purity rules. It is therefore powerful evidence for how the state sought to codify hierarchy. It is not a neutral ethnographic census proving that every household used the same identities, names, or rank in everyday social life. This book accordingly distinguishes legal classification from social self-description. The same rule underlies its treatment of Panji categories in Mithila: a state or elite classification can become historically consequential without being projected backward as a timeless community structure. Land as fiscal infrastructure Rana-era government depended heavily on rights over land, revenue, labour and forest resources. Land categories distributed fiscal obligations and privileges while linking service to office. Mahesh C. Regmi’s studies remain fundamental because they reconstruct these institutions from revenue and land records rather than from later constitutional categories (Regmi 1976; Regmi 1978). The Tarai’s expansion of taxable cultivation made land policy especially important. Yet “reclamation” should be read critically: converting forest or grassland into assessed fields could increase state revenue while displacing uses and claims that were poorly represented in agrarian registers. Raikar: revenue-paying land Raikar generally referred to land subject to state revenue. The category helps identify the fiscal relationship between cultivators or holders and the state, but it does not by itself identify one modern ownership form. Rights could be layered through tenancy, local office, mortgage, inheritance and customary practice. Comparing raikar with Bengal’s Permanent Settlement is useful only at the level of mechanisms. Nepal did not simply reproduce the Bengal zamindari constitution; its fiscal categories emerged through different legal and political histories. Birta: privileged grants and political economy Birta grants transferred land or revenue rights under privileged conditions and became important instruments of reward and elite accumulation. Their scale, exemptions, heritability and later regulation varied. They illustrate how political authority could be converted into long-term claims on agrarian surplus (Regmi 1976). Because birta holders and cultivators held different kinds of claims, the existence of a grant should not be read as proof that cultivators had no rights or that every grant functioned identically. The document, locality and date remain decisive. Jagir, guthi, and service-linked assignments Jagir linked revenue or land rights to office and service, while guthi property supported religious, charitable or institutional purposes under varying arrangements. Other labour and service obligations further connected households to the fiscal state. These categories formed a political economy of assignment rather than a simple market in private freehold. They also help explain why twentieth-century reform could not be reduced to abolishing one landlord class: the institutional landscape contained several kinds of revenue and service rights. Nepalese jimidar and the danger of translating “zamindar” Terms rendered as jimidar or zamindar in Nepalese records should not be assumed to carry the same bundle of rights as a Permanent Settlement zamindar in Bihar. Similar vocabulary travelled across languages and administrative worlds, but legal content depended on the state system in which the office operated. For comparative history, the safer questions are who assessed or collected revenue, who held recognized claims, who could transfer or inherit them, and what obligations followed. Translation by institutional function is more reliable than translation by familiar title. Reclamation before Rana rule Expansion of cultivated land in the eastern Tarai predated the Rana oligarchy. Late eighteenth-century Shah-period revenue measures already categorized cultivable tracts and encouraged the fiscal incorporation of new fields. Rana policy intensified and reorganized processes that had earlier roots (Regmi, Economic History of Nepal). This chronology prevents a common error: the Tarai was neither “opened” suddenly in 1846 nor empty before Rana- sponsored migration. Forest use, local settlement and state interest all had longer histories. Reclamation incentives, contractors, and local intermediaries Agricultural expansion often required intermediaries who recruited cultivators, advanced resources, cleared land or guaranteed revenue. Such arrangements could generate new local elites and expose cultivators to multiple demands. They also linked the Tarai more closely to adjoining districts of British India through migration and credit. The state’s objective of increasing taxable cultivation did not guarantee secure tenure for everyone who performed the labour of clearance. Rights had to be documented, defended and transmitted within administrative systems that privileged some forms of evidence over others. Forest as revenue, timber, and territorial resource Tarai forests supplied timber, fuel, grazing, hunting grounds, elephant habitats and other resources. Their conversion into assessed agriculture increased revenue in some places while commercial extraction turned other areas into strategic resource zones. Forest history must therefore include both conservation and dispossession. The categories “waste” and “jungle” in official writing often described land from the viewpoint of fiscal or commercial utilization and could obscure existing livelihood systems. Long-settled Tarai communities and the archive of absence Tharu and other long-established communities demonstrate why the plains cannot be narrated only as a history of migrants arriving from India or hills. Pastoral, forest, fishing, agricultural and mixed livelihoods could leave fewer revenue documents than newly assessed fields while still representing durable occupation. Silence in tax or census records is therefore not evidence of emptiness. The source-controlled approach asks what type of activity a document was designed to record and which groups were easiest for that institution to see. Malaria: ecology without determinism Malaria profoundly affected settlement, seasonal movement, labour and official perceptions of the Tarai. Risk varied by locality, drainage, altitude, housing, season, immunity and access to treatment; it should not be turned into a single environmental explanation for political or ethnic history. Officials frequently described the plains as unhealthy or dangerous while towns, markets and established communities continued to exist there. Such descriptions are evidence for disease and for the political imagination of the region at the same time. Tharu malaria research and its limits Late twentieth-century biomedical studies reported markedly lower malaria morbidity among sampled Tharu populations than among sympatric non-Tharu groups and investigated genetic factors such as alpha-thalassaemia (Terrenato et al. 1988; Modiano et al. 1991). These studies are retrospective biomedical evidence from sampled populations, not proof of absolute “immunity,” a timeless biological essence, or one explanation for Tharu history. Historical settlement still requires social, ecological and documentary evidence. Migration from British India and within Nepal Cultivation, trade, rent opportunities, labour demand and political patronage drew migrants into the Tarai from adjoining British Indian districts and from other parts of Nepal. Migration could be seasonal, circular or permanent and often relied on kin or merchant networks rather than a one-time state colonization programme (Gaige 1975). The same process produced unequal claims to belonging. Long residence, tax payment, land documents, language and political loyalty did not always translate into identical access to offices or later citizenship regimes. The eastern Tarai as a multilingual social field The eastern and central Tarai included Maithili, Bhojpuri, Urdu, Nepali, Tharu languages and other speech traditions in overlapping markets, households, schools, courts and religious institutions. Language use changed with setting: household speech, written petitions, commercial accounts and schooling could employ different languages. The chapter therefore avoids reading a later census language category backward as if it were the only social identity available in the nineteenth century. Multilingual practice is not evidence of weak identity; it is a historical feature of borderland life. Maithili across a state boundary Maithili literary and social networks crossed the international frontier, particularly between north Bihar and the eastern- central Tarai. Print, education, marriage, pilgrimage, performance and employment could connect communities subject to different states. This connected field does not erase Nepalese sovereignty or make the Tarai an extension of Bihar. It demonstrates why language geography and state territory must be kept analytically separate: the same language community can inhabit more than one political order. Janakpur: pilgrimage, town, and border-connected centre Janakpur linked sacred geography with markets, transport, education and regional identity. Pilgrimage from India sustained traffic across the frontier, while the town’s institutions also belonged to Nepalese administrative and political history. Its importance illustrates a recurring principle of this book: sacred continuity can be historically real even when claims about the antiquity of a particular modern building or route require separate evidence. Border markets, customs, and everyday sovereignty Customs posts, excise, policing and legal jurisdiction made the boundary materially visible, yet nearby markets depended on movement across it. Grain, livestock, timber, cloth, salt, manufactured goods, currency and labour circulated through regulated and unregulated channels. Sovereignty at the border was therefore exercised by selecting, taxing, documenting or prohibiting particular movements rather than by preventing all movement. The later language of an “open border” should not obscure this longer history of selective regulation. Currency, credit, and merchant networks Commercial exchange required currency conversion, credit, brokerage and trust across jurisdictions. Merchant houses and moneylenders could connect village production to Indian railheads and wider markets even where road infrastructure inside Nepal remained limited. These networks made the border economically porous without making it legally irrelevant. Debt disputes, customs liability and contractual enforcement still depended on institutions located on one side or the other. The Nepal Government Railway and Raxaul–Birgunj–Amlekhganj The narrow-gauge Nepal Government Railway opened in 1927 between the Indian railhead at Raxaul and Amlekhganj through Birgunj. For decades it formed a major avenue for goods and passengers travelling between India, the Tarai and the approach to Kathmandu (World Bank 1965). Its transshipment structure is historically revealing: Indian and Nepalese networks met at a border customs point rather than forming one seamless railway system. Transport integration therefore increased crossing while reinforcing places where sovereignty was inspected and charged. Jaynagar–Janakpur railway and the problem of exact opening dates The narrow-gauge line from the Indian rail network at Jaynagar into the Janakpur area was originally associated with timber traffic and later became important for pilgrims and local passengers. Modern Nepal railway histories commonly place its opening in the 1930s, often 1937. At least one later World Bank transport history gives a different early date for the Janakpur system. This book therefore records the 1930s railway horizon and flags the exact opening year for confirmation from contemporary railway records rather than manufacturing certainty from inconsistent later summaries. Railheads and asymmetric access to Kathmandu Before all-weather road connection to Kathmandu, the Tarai railways did not remove the topographical break between plains and valley. Passengers and freight still changed mode at the foot of the hills. The resulting transport system tied Tarai border towns closely to Indian railways while leaving the capital connected through a more difficult final stage. This asymmetry mattered politically and economically. The border could be closer in travel time to Calcutta, Patna or north- Bihar towns than Kathmandu was to some lowland localities, without changing formal sovereignty. The first nationwide census of 1911 Nepal’s official census history identifies 1911 as the first population census covering the country, followed at roughly ten- year intervals. Earlier counts existed for narrower purposes, but the 1911 enumeration established a new nationwide administrative practice (National Statistics Office, Nepal). The existence of a census should not be confused with modern statistical completeness. The first four censuses—1911, 1920, 1930 and 1941—were conducted under the Rana regime with limited schedules and published chiefly as aggregate headcounts. The limits of the Rana-era censuses Official retrospective assessments emphasize that the pre-1952/54 censuses lacked the concepts, definitions, classifications and field organization of later modern censuses. Historical demographic work also notes weak supervision and the use of local agents in enumeration. These counts remain valuable administrative evidence, but precision must match their design. They can anchor broad population history more safely than detailed claims about language, caste, migration or identity that the published tables did not consistently disclose.

Counting and the politics of social categories Later census scholarship notes that language, religion and caste/ethnicity were not published with the same systematicity as in later democratic-era censuses. Enumeration is therefore part of the history of state knowledge: what government chose to count and publish changed over time. For the Tarai, this is particularly important because later political arguments often cite demographic categories as if they were timeless. The chapter uses only categories actually available in the named census and does not infer an earlier ethnic distribution from a later table. The Britain–Nepal Treaty of 1923 The treaty signed at Kathmandu on 21 December 1923 replaced and confirmed parts of the earlier British–Nepal relationship. Article I stated mutual recognition and respect for the internal and external independence of both contracting parties, making the wording an important diplomatic anchor (Treaty between the United Kingdom and Nepal, 1923). The treaty did not erase asymmetry in arms, trade, transit or imperial strategy. Its significance lies precisely in the coexistence of formal interstate recognition with continued material dependence on routes and markets through British India. Independence in treaty language and dependence in infrastructure Rana Nepal maintained independent treaty personality while relying heavily on British Indian ports, railways and markets. The distinction between sovereignty and connectivity prevents two opposite errors: calling Nepal a British colony, or imagining it as economically sealed from the Raj. The Tarai was where the two realities met most visibly— customs posts, railheads, timber traffic, military recruitment, merchants and political travellers turned interstate relations into everyday institutions. Schools, language, and access to the state Education under Rana rule remained restricted and uneven. Access to schooling, official employment and documentary literacy was stratified by region and social position. For plains communities, the languages of household, market, religious learning and state office could differ. Later language politics cannot simply be projected backward onto this unequal educational field. The historical question is which institutions used which language and who gained access to them at a particular date. Industrial eastern Tarai and Biratnagar Jute Mills Biratnagar Jute Mills was incorporated in 1936 and is conventionally treated as Nepal’s first major modern industrial enterprise. Its location near the Indian border joined Tarai agricultural production, imported machinery, merchant capital, labour and cross-border transport (Government of Nepal, Ministry of Finance; Gaige 1975). Industrialization did not replace agrarian society. It created a concentrated wage-labour arena within a region still dominated by agriculture, trade and land relations, and that new arena became politically consequential in 1947. The March 1947 Biratnagar labour strike A strike in the Biratnagar jute and cotton mills in March 1947 brought industrial labour grievances into the anti-Rana political movement. Repression of the strike became an issue for Nepali National Congress activists and their allies across the border. The event is important not because it alone caused the end of Rana rule, but because it linked workplace conflict, civil-liberties demands and borderland political organization in a way that older palace-centred narratives can miss. Jogbani, 10 April 1947: a border town as political platform A Nepali National Congress meeting at Jogbani in north Bihar on 10 April 1947 decided to begin a country-wide satyagraha from 13 April, protesting repression of the Biratnagar mill strike and demanding civil liberties. Contemporary Nehru papers preserve the date and purpose of the meeting. Jogbani’s role shows that the border was not merely crossed after political decisions were made elsewhere. Border towns themselves could become organizational spaces because activists, labour centres, Indian political contacts and Nepalese territory lay in close proximity. Indian independence and the remaking of border politics On 15 August 1947 the southern side of the frontier ceased to be British India. Nepal’s Rana regime remained in power, so the borderland entered a period in which one state had undergone decolonization while the other retained oligarchic rule. Indian independence altered diplomatic expectations and the political opportunities available to Nepalese activists, but it did not give them unrestricted freedom to use Indian territory for armed action. Indian authorities later tried to distinguish political sympathy from permission to operate military bases across the border. Political exile and organization in India Nepalese political activists used Banaras, Calcutta, north- Bihar towns and other Indian locations for education, publication, party organization and refuge. These connections were enabled by older mobility networks but acquired new significance as mass politics expanded. A history of Nepalese democratization written only from Kathmandu therefore misses an important geography of political production. At the same time, cross-border organizing should not be rewritten as proof that the movement was externally created; Nepalese actors used spaces available to them for their own political projects. The 1950 Treaty of Peace and Friendship India and Nepal signed the Treaty of Peace and Friendship at Kathmandu on 31 July 1950, and Article 9 made it effective from the date of signature. Article 1 mutually recognized complete sovereignty, territorial integrity and independence (United Nations Treaty Series, No. 1302). The treaty belongs to the postcolonial interstate order and should not be treated as the origin of every form of cross-border mobility. Kinship, pilgrimage, work and commerce had long crossed the frontier; the treaty formalized a new reciprocal framework between two sovereign governments. Article 7 and reciprocal privileges Article 7 provided, on a reciprocal basis, comparable privileges for nationals of each country in the other concerning residence, property ownership, trade and commerce, movement and similar matters. The wording is broader than a simple visa clause and became central to later descriptions of the open border. Actual practice nevertheless remained shaped by domestic citizenship, land, security, labour and administrative law. “Open border” is therefore an analytical shorthand for a distinctive regime of mobility, not a claim that the frontier ceased to exist legally. Article 8 and the break with British-era agreements Article 8 cancelled, for matters covered by the 1950 treaty, previous treaties, agreements and engagements concluded on behalf of India between the British Government and Nepal. This clause marks the legal transition from an imperial relationship to a bilateral postcolonial one. It did not erase the historical consequences of Sugauli, the 1816 restoration, 1860 boundary settlement, or 1923 treaty. Those instruments remain evidence for how the frontier and interstate relationship had been made before 1950. November 1950: monarchy, insurgency, and the border The political crisis sharpened in November 1950 when King Tribhuvan took refuge in the Indian embassy and Nepali Congress forces launched action from the border region, including at Birgunj. Indian correspondence shows simultaneous concern with Nepalese political change and instructions that Indian territory not simply become an armed base. The episode demonstrates why the borderland cannot be described only as either “open” or “closed.” Political refugees, party organizers, armed groups, police and diplomats encountered different rules and tolerances even along the same frontier. Negotiation, the Delhi compromise, and the end of Rana monopoly Negotiations among the king, Rana leadership, Nepali Congress and India produced a compromise rather than an outright military conquest of Kathmandu. The result preserved the monarchy, brought party representatives into government, and ended the Rana family’s exclusive grip on executive power. This negotiated character matters because institutions and elites survived the transition in altered forms. February 1951 was a decisive break in political regime, not a total institutional blank slate. 15 February 1951: Tribhuvan’s return King Tribhuvan returned to Kathmandu on 15 February 1951 after the political settlement. His return symbolized the restoration of royal authority against the Rana prime-ministerial monopoly and created the setting for an interim coalition order. The event is best understood within a sequence—border insurgency, negotiation, return, proclamation and coalition government—rather than as a single dramatic moment that by itself created democracy. 18 February 1951: proclamation and interim government A royal proclamation of 18 February 1951 announced a new political order and a ministry combining Rana and Nepali Congress representation, while promising movement toward government based on a democratic constitution. The resulting coalition was unstable, but the Rana oligarchy as the exclusive governing system had ended (Joshi and Rose 1966; contemporary diplomatic records). The transition opens Volume V’s contemporary history. It did not resolve land inequality, citizenship, language, representation or the status of the Tarai/Madhesh; instead, those questions entered new electoral, constitutional and administrative arenas. Sovereignty and social continuity: a source-controlled conclusion From Sugauli to 1951 the Tarai borderland experienced increasingly precise state sovereignty without becoming socially sealed. Treaties, revenue systems, law codes, censuses, customs and railways made jurisdiction more visible, while migration, kinship, commerce, pilgrimage and political organization continued to cross it. The strongest regional history therefore refuses both false unity and false separation. Nepal and India/British India were different political orders; the Tarai and north Bihar were also connected through institutions that can be documented at particular dates. The task is to preserve both propositions at once. Chapter-specific bibliography East India Company and Kingdom of Nepal. Treaty of Sugauli.
