The Treaty of Yandaboo (1826) was a historic agreement signed between the British East India Company and the Kingdom of Burma (Myanmar) after the First Anglo-Burmese War (1824–1826).
This treaty marked a turning point in the political and administrative history of Northeast India, leading to the expansion of British colonial control and the eventual integration of the region into British India.

Often referred to as the foundation stone of British rule in Northeast India, the Treaty of Yandaboo reshaped Assam, Manipur, and surrounding territories, influencing their political, economic, and social trajectories for centuries.

For UPSC, APSC, ADRE, TET, and other competitive exam aspirants, the Treaty of Yandaboo is an important topic under Modern Indian History, especially in the context of British expansion in India and colonial administration in Northeast India.

Historical Background of the Treaty of Yandaboo

The treaty was signed between:

• The British East India Company
• The Kingdom of Ava (Burma)

Rise of Burmese Expansionism

In the late 18th and early 19th centuries, the Burmese kingdom aggressively expanded westward. Burma annexed:

• Arakan (1784)
• Manipur (early 19th century)
• Assam (around 1817–1821 during internal Ahom conflicts)

This expansion brought Burma into direct conflict with British-controlled Bengal.

Causes of the First Anglo-Burmese War (1824–1826)

The Treaty of Yandaboo cannot be understood without examining the causes of the First Anglo-Burmese War.

1. Burmese Expansion into Assam and Manipur

Burma took advantage of political instability in Assam during the decline of the Ahom dynasty. Their occupation alarmed the British.

2. Border Disputes with British India

Frequent clashes occurred in:

• Cachar
• Jaintia
• Chittagong frontier

Both sides accused each other of territorial encroachments.

3. Strategic Concerns of the British

The British feared that Burmese expansion might threaten:

• Bengal Presidency
• Trade routes
• British influence in Eastern India

As a result, war broke out in 1824.

The First Anglo-Burmese War: A Brief Overview

The First Anglo-Burmese War (1824–1826) was:

• The longest and most expensive war fought by the British in India up to that time.
• Conducted mainly in difficult terrain, including jungles, rivers, and marshlands.

The war severely weakened Burma militarily and economically. Eventually, British forces advanced close to the Burmese capital, forcing the Burmese king to negotiate peace.

This led to the signing of the Treaty of Yandaboo in February 1826.

Provisions of the Treaty of Yandaboo (1826)

The Treaty of Yandaboo contained several significant clauses that reshaped the political map of the region.

1. Territorial Cessions

Burma ceded the following territories to the British:

• Assam
• Manipur
• Arakan (Rakhine)
• Tenasserim

This marked the formal beginning of British rule in Assam (1826).

2. Recognition of Manipur’s Independence

Burma recognized Manipur as an independent state and renounced all claims over it.

3. War Indemnity

Burma agreed to pay:

• One crore rupees (10 million rupees)
• To be paid in installments

This indemnity deeply strained the Burmese economy.

4. Diplomatic Relations

• Both sides agreed to exchange diplomatic representatives.
• A British Resident would be stationed at Ava.

This provision increased British influence inside Burma.

Impact of the Treaty of Yandaboo on Assam

The Treaty of Yandaboo, 1826, marked the beginning of a new chapter in Assam’s history.

1. End of Ahom Rule

Although the Ahom kingdom had already weakened, the treaty formally ended indigenous political authority.

2. Beginning of British Administration

Assam was gradually integrated into British India. Administrative reforms included:

• Revenue settlements
• Judicial systems
• Infrastructure development

3. Tea Plantation Economy

British control opened the door to:

• Discovery of indigenous tea plants
• Establishment of tea plantations
• Introduction of indentured labor

Assam soon became a major tea-producing region.

4. Socio-Economic Transformation

British policies altered:

• Land ownership patterns
• Tribal governance structures
• Trade and commercial networks

Impact of the Treaty of Yandaboo on Burma (Myanmar)

The Treaty of Yandaboo (1826) had very bad effects on Burma. It was a humiliating and painful treaty for the Burmese kingdom.

1. Territorial Loss

Burma had to give up many important areas to the British. These included coastal and border regions like Assam, Manipur, Arakan, and Tenasserim. Losing these lands weakened Burma’s power and reduced its control in the region.

2. Economic Crisis

Burma had to pay a huge amount of money (war indemnity) to the British. This damaged the Burmese economy. The government became poor and could not manage the country properly.

3. Political Instability

After the treaty, the Burmese monarchy became weak. The British started interfering in Burma’s internal affairs. This led to more wars:

• Second Anglo-Burmese War (1852)
• Third Anglo-Burmese War (1885)

Finally, in 1885, Burma was completely taken over by the British and became a British colony.
