1. The Treaty of Allahabad and the Grant of Diwani (1765) (basic)
To understand how a trading company became the masters of India, we must look at the
Treaty of Allahabad (1765). While the Battle of Buxar (1764) was the military knockout blow, this treaty was the legal document that formalized British political power. After the victory, Robert Clive concluded two separate agreements in August 1765: one with the
Nawab of Awadh (Shuja-ud-Daula) and the other with the
Mughal Emperor (Shah Alam II) Rajiv Ahir. A Brief History of Modern India, Expansion and Consolidation of British Power in India, p.92.
The most transformative part of this treaty was the
Grant of Diwani. Shah Alam II issued a royal
farman (decree) granting the East India Company the right to collect revenues from the provinces of
Bengal, Bihar, and Odisha. In return, the Company agreed to pay the Emperor an annual sum of Rs 26 lakh and took over the
Nizamat (administrative and military) responsibilities for a fee of Rs 53 lakh
Rajiv Ahir. A Brief History of Modern India, Expansion and Consolidation of British Power in India, p.92. This effectively meant the British now controlled the purse strings of the richest part of India, transitioning from mere merchants to a
formidable political force History, class XI (Tamilnadu state board 2024 ed.), Effects of British Rule, p.265.
A fascinating but often overlooked consequence of this grant was its
geographical impact. By acquiring the revenue rights of Bengal, the British suddenly found themselves administering the
Sylhet district (now in Bangladesh). This new frontier brought the British into their very first direct contact with the mountain tribes of the Northeast, specifically the
Khasis, who lived in the hills bordering Sylhet. Initial interactions were driven by trade in lime, silk, and iron, marking the beginning of British expansion into the tribal hinterlands of India.
1764 — Battle of Buxar: The military defeat of the Triple Alliance (Mir Qasim, Shuja-ud-Daula, Shah Alam II).
1765 (August) — Treaty of Allahabad: British gain legal control over Bengal's revenue (Diwani).
| Party | Key Terms of the Treaty |
|---|
| Nawab of Awadh | Ceded Allahabad and Kara to the Emperor; paid Rs 50 lakh war indemnity. |
| Mughal Emperor | Granted Diwani of Bengal, Bihar, and Odisha to the Company; resided at Allahabad under British protection. |
Key Takeaway The Treaty of Allahabad legally converted the British East India Company from a commercial entity into the de facto rulers of Eastern India by granting them the rights to revenue (Diwani) and administration (Nizamat).

2. Expansion into the Frontier: The Sylhet-Khasi Connection (intermediate)
After the Grant of Diwani in 1765, the British East India Company transitioned from mere traders to the revenue administrators of Bengal, Bihar, and Odisha Modern India (Old NCERT), Bipin Chandra, The Structure of the Government and the Economic Policies of the British Empire in India, 1757—1857, p.88. This administrative shift pulled the British toward the northeastern frontier. Specifically, they inherited control over the Sylhet district (located in present-day Bangladesh), a fertile plain that shared a direct land border with the Khasi Hills. Because of this geographical contiguity, the Khasis became the first mountain tribe the British encountered in the northeast.
Initial contact was driven by commercial interests rather than immediate military conquest. The British were eager to tap into the regional trade of the Khasi Hills, which were a primary source of lime (essential for construction in the growing city of Calcutta), iron, and silk. While iron ore has always been a cornerstone of the Indian economy Geography of India, Majid Husain, Resources, p.7, the immediate logistical need for lime brought British administrators in Sylhet into direct negotiations with Khasi chiefs as early as 1765–1771.
It is vital for a UPSC aspirant to understand the chronology of frontier contact to grasp how British influence radiated outward from Bengal. While the Khasis were met almost immediately, other tribes like the Garos were encountered only toward the end of the 18th century. Further groups, such as the Kukis and Tipperahs, did not see significant British interaction until the 19th century, during the expansion into the Lushai Hills and the Chittagong Hill Tracts History (TN State Board), Reconstruction of Post-colonial India, p.102.
1765 — Grant of Diwani: British East India Company acquires revenue rights over Bengal and Sylhet.
1765–1771 — Early Frontier Contact: British administrators in Sylhet establish trade links with the Khasis.
Late 18th Century — Interior Expansion: British contact extends to the Garo tribes.
19th Century — Deep Frontier: Interactions begin with the Kukis and Lushai tribes.
Key Takeaway The Khasis were the first mountain tribe the British encountered post-1765 because the Khasi Hills bordered the Sylhet district, which the British acquired immediately following the Grant of Diwani.

3. Early Tribal Resistance and British Land Policy (intermediate)
To understand tribal resistance, we must first look at the
1765 Grant of Diwani. This single event transformed the British East India Company from a group of merchants into the supreme revenue collectors of Bengal, Bihar, and Odisha. This shift didn't just affect the plains; it brought the British to the doorstep of the hills. The British were drawn to tribal regions primarily for two reasons:
securing trade routes and
extracting natural resources like lime, silk, and iron. Because of its geographic proximity to the newly acquired Sylhet district (now in Bangladesh), the
Khasi tribe became the first mountain tribe to come into direct contact with British administration between 1765 and 1771.
Rajiv Ahir, A Brief History of Modern India (SPECTRUM), People’s Resistance Against British Before 1857, p.157The core of the friction, however, was a fundamental clash of
Land Policy. Unlike previous Indian rulers who collected a share of the actual harvest, the British introduced a system where land revenue was treated as a
fixed rent. This meant the revenue had to be paid regardless of whether the crops succeeded or failed.
History, class XI (Tamilnadu state board), Early Resistance to British Rule, p.293. This commercialization of land opened tribal territories to 'outsiders' (often called
Dikus), such as moneylenders and contractors, who displaced the original inhabitants.
| Feature | Pre-British Tribal Land Custom | British Colonial Land Policy |
|---|
| Revenue Logic | Tax based on actual crop yield. | Fixed rent based on land area. |
| Ownership | Communal/Ancestral holding. | Private property with legal titles. |
| Defaulting | Negotiable during famine/drought. | Land was confiscated and auctioned. |
This systemic pressure led to a chain reaction of uprisings across the 19th century. For instance, the
Kol Uprising (1831–1832) in Chota Nagpur was a direct response to policies that favored outsiders over the Mundas and Oraons.
Exploring Society: India and Beyond, Class VIII NCERT, The Colonial Era in India, p.106. Similarly, the
Ho tribals of Singhbhum revolted in the 1820s against the occupation of their territory and the new farming revenue policies.
Rajiv Ahir, A Brief History of Modern India (SPECTRUM), People’s Resistance Against British Before 1857, p.157.
1765 — Grant of Diwani; British contact with Khasis near Sylhet.
1820-1837 — Ho tribal resistance against revenue policy in Singhbhum.
1831-1832 — Kol Uprising in Chota Nagpur against land displacement.
1855-1856 — Santhal Rebellion against moneylenders and British land support.
Key Takeaway Tribal resistance was not just a reaction to foreign presence, but a desperate defense against the British 'land-as-rent' policy which incentivized the influx of exploitative middlemen into ancestral territories.

4. Connected Concept: The Anglo-Burmese Wars and NE Expansion (exam-level)
The British expansion into Northeast India was not a single event but a gradual process triggered by the
Grant of Diwani in 1765. When the East India Company acquired the right to collect revenue in Bengal, they inherited the
Sylhet district (modern-day Bangladesh). This brought them into immediate geographical proximity with the mountain tribes of the frontier, most notably the
Khasis, who occupied the hills between the Jaintia and Garo ranges. Initial contact was driven by trade interests in lime, silk, and iron, marking the Khasis as the first mountain tribe the British encountered in this region
Rajiv Ahir, A Brief History of Modern India, Expansion and Consolidation of British Power in India, p.126.
By the early 19th century, this commercial interest evolved into a strategic conflict known as the Anglo-Burmese Wars. The Burmese Empire, under the Konbaung dynasty, was expanding westward, conquering Arakan, Manipur, and Assam. This expansion created a 'shatter zone' where British and Burmese interests collided along an ill-defined border. The threat to the Brahmaputra Valley and the potential for a Burmese invasion of Bengal led to the First Anglo-Burmese War (1824-26). Despite fierce guerrilla resistance in the jungles, the British forces utilized their naval superiority to occupy Rangoon and advance toward the capital at Ava Bipin Chandra, Modern India, India And Her Neighbours, p.170.
The war concluded with the Treaty of Yandabo (1826), which fundamentally reshaped the map of Northeast India. Under this treaty, the Burmese government agreed to pay a war indemnity of one crore rupees and, crucially, abandoned all claims to Assam, Cachar, and Manipur. This vacuum allowed the British to move from the plains into the hills. However, this expansion met with stiff resistance from indigenous tribes. For instance, when the British attempted to build a road through the Khasi Hills to link Assam with Sylhet, it led to the Khasi insurrection (1829-1833) led by Tirut Singh. This pattern of expansion—annexing passes for tea cultivation and suppressing tribal raids—continued well into the late 19th century, including conflicts with Bhutan in 1865 Rajiv Ahir, A Brief History of Modern India, Expansion and Consolidation of British Power in India, p.125.
1765 — Grant of Diwani; British reach the Sylhet border near Khasi Hills.
1824-26 — First Anglo-Burmese War triggered by Burmese expansion into Assam.
1826 — Treaty of Yandabo: Burma cedes coastal provinces and drops claims to Assam.
1865 — Bhutanese forced to surrender Himalayan passes in exchange for a subsidy.
Key Takeaway The British entry into the Northeast was a shift from revenue collection in Bengal (1765) to strategic annexation (1826) aimed at creating a buffer zone against the Burmese Empire.

5. The Khasi Uprising and U Tirut Singh (exam-level)
To understand the Khasi Uprising (1829–1833), we must first look at the map. Following the British victory in the First Anglo-Burmese War and the Treaty of Yandabo (1826), the East India Company gained control over the Brahmaputra Valley in Assam. However, they already held the Sylhet region in Bengal. To move troops and goods efficiently between these two occupied territories, the British planned a strategic road right through the Khasi Hills, which sat directly between the Garo and Jaintia ranges Rajiv Ahir, A Brief History of Modern India, People’s Resistance Against British Before 1857, p.160.
The conflict wasn't just about the road itself, but the socio-economic disruption it brought. The British didn't just bring engineers; they brought an influx of "outsiders"—English officers, Bengali tax collectors, and laborers from the plains. For the Khasis, who had long maintained their independence and unique cultural identity, this was seen as a direct threat to their sovereignty and their control over local resources like lime and iron. U Tirut Singh, the Syiem (Chief) of Nongkhlaw, initially allowed the road project but soon realized the British intention was permanent political subjugation rather than a simple right-of-way.
1826 — Treaty of Yandabo; British gain control over Assam and seek connectivity with Bengal.
1829 — U Tirut Singh leads a surprise attack on the British at Nongkhlaw, marking the start of the uprising.
1829-1833 — A protracted guerrilla war involving Khasi, Garo, and Singpho tribes against British forces.
1833 — U Tirut Singh is captured; the uprising is suppressed by superior British military technology Rajiv Ahir, A Brief History of Modern India, People’s Resistance Against British Before 1857, p.160.
The resistance was remarkable for its scale. It wasn't just a Khasi affair; Tirut Singh successfully organized a confederacy that included the Garos, Khamptis, and Singphos. They utilized the difficult hilly terrain to conduct a guerrilla struggle for nearly four years. However, the East India Company utilized its scorched-earth tactics and superior weaponry to eventually crush the rebellion. By 1833, the hills were brought under British administrative control, marking a critical step in the annexation of North-East India.
| Feature |
Khasi Uprising (1829-1833) |
| Primary Trigger |
Construction of a road connecting Sylhet to the Brahmaputra Valley. |
| Key Leader |
U Tirut Singh (Syiem of Nongkhlaw). |
| Tribal Unity |
United Khasis, Garos, Khamptis, and Singphos against "outsiders." |
Key Takeaway The Khasi Uprising was a reaction against British infrastructural expansion and the resulting influx of outsiders, showcasing an early and organized tribal resistance to colonial annexation in North-East India.

6. Chronology of British Contact with North Eastern Tribes (exam-level)
To understand the British entry into the North East, we must look at the
Grant of Diwani in 1765. When the British East India Company acquired the right to collect revenues in Bengal, they suddenly became neighbors to the hill tribes of the North East. The first point of contact was the
Sylhet district (in modern-day Bangladesh), which bordered the Khasi Hills. Unlike later military expeditions, this initial interaction was driven by
commercial interests—the Khasis controlled rich resources like lime, silk, and iron, which the British were eager to trade
Modern India (Old NCERT), India And Her Neighbours, p.178.
As the British moved further into the frontier, the nature of contact shifted from trade to conflict and administration. While the Khasis were contacted as early as 1765-1771, the Garos were encountered later in the 18th century. A massive shift occurred after the Treaty of Yandabo (1826), which ended the First Anglo-Burmese War. This treaty gave the British control over Assam, leading to immediate and often violent contact with the Bhutanese and tribes like the Nagas and Kukis as the British attempted to secure their new borders and stop tribal raids into the plains Spectrum, Expansion and Consolidation of British Power in India, p.125.
1765-1771 — Initial contact with the Khasis via the Sylhet border for trade.
Late 18th Century — Gradual contact with the Garos as the frontier expanded.
1824-1826 — First Anglo-Burma War; Treaty of Yandabo opens Assam and brings contact with Bhutanese and Nagas.
Mid-Late 19th Century — Expansion into Lushai Hills leads to contact with Kukis and Tipperahs.
The British policy was rarely uniform. In some areas, they sought "Masterly Inactivity" or simple trade, while in others, they pursued "Forward Policies" to secure mineral-rich or strategically vital highlands Modern India (Old NCERT), India And Her Neighbours, p.181. The chronology of contact was therefore dictated by geographical proximity to Bengal and the commercial value of the tribal lands.
Key Takeaway British contact with North Eastern tribes moved from West to East, starting with the Khasis (1765) due to their proximity to the Sylhet plains and their valuable trade resources.

7. Solving the Original PYQ (exam-level)
This question bridges the gap between your study of administrative history (the 1765 Grant of Diwani) and the tribal frontier policy of the British. When the East India Company secured revenue rights over Bengal, Bihar, and Odisha, their administrative boundaries suddenly touched the mountainous frontiers of the Northeast. The key to solving this lies in mapping the Sylhet district—the easternmost point of the then Bengal Presidency—to its immediate neighbors. As you learned in A Brief History of Modern India by Rajiv Ahir (Spectrum), British interest was rarely just territorial; it was driven by the commercial extraction of resources like limestone, silk, and iron found in the hills adjacent to these newly acquired plains.
To arrive at the correct answer, (B) Khasis, you must apply geographical sequencing. Immediately after 1765, British officials in Sylhet sought to trade with the people occupying the hills directly above them. The Khasis, inhabiting the range between the Jaintia and Garo hills, were the first to engage in this trade and subsequent friction. Think of it as a ripple effect: the British didn't jump deep into the interior; they interacted with the tribes on the immediate "rim" of their new revenue lands. The Garo tribe, while nearby, came into significant contact slightly later as the British pushed further west, while the Kukis and Tipperahs represent a common UPSC chronological trap; these groups were encountered much later in the 19th century during the expansion toward the Lushai Hills and the Chittagong Hill Tracts.
