Answer: (C) Rajendra I (Chola)

Rajendra I (also known as Rajendra Chola I) was one of the greatest rulers of the Chola dynasty, reigning from 1014 to 1044 CE.

He is famous for his extraordinary naval expeditions, particularly the campaign against the Srivijaya Empire.

The Srivijaya Empire was a powerful maritime kingdom based in Sumatra (modern-day Indonesia) that controlled the strategically vital Strait of Malacca — the key shipping route between India and China.

Around 1025 CE, Rajendra I launched a massive naval campaign against Srivijaya. His navy sailed across the Bay of Bengal and attacked multiple Srivijaya territories including parts of the Malay Peninsula, Sumatra, and nearby islands.

Why did he attack? The Srivijaya Empire was disrupting Chola trade routes to China and Southeast Asia. By defeating them, Rajendra I secured Chola commercial interests in the region.

This naval expedition is remarkable because it was one of the few instances in ancient Indian history where a kingdom projected military power overseas across an ocean. It demonstrates the Chola dynasty's exceptional naval capabilities.

The other rulers listed — Amoghavarsha (Rashtrakuta), Prataparudra (Kakatiya), and Vishnuvardhana (Hoysala) — were all important in peninsular India but did not conduct overseas military campaigns.

Answer is (c).

Why this was asked

Rajendra I's 1025 CE naval campaign against Srivijaya was one of the rare instances in ancient Indian history where a kingdom projected military power across oceans to secure trade routes.

The campaign targeted Srivijaya's control over the Strait of Malacca, the crucial shipping route between India and China, demonstrating how medieval Indian rulers understood maritime trade geopolitics.

UPSC is testing whether students can distinguish between rulers who fought land-based campaigns in peninsular India versus those who conducted overseas naval expeditions.

Question Context

This UPSC question tests knowledge of which ruler conducted overseas military campaigns. Only Rajendra I among the given options projected naval power beyond India's shores to Southeast Asia.

Exam traps

Don't confuse Rajendra I with Rajaraja I — both were great Chola naval rulers

Amoghavarsha (Rashtrakuta) was powerful but focused on Deccan, not overseas campaigns

Remember: Srivijaya was based in Sumatra (Indonesia), not peninsular India

1025 CE is the key date for the Srivijaya expedition

Srivijaya Maritime Empire

Ancient And Medieval History Srivijaya Malay Peninsula Sumatra Java

Srivijaya Empire: Maritime Power of Southeast Asia

Must know

Srivijaya Empire (7th-13th centuries) controlled Strait of Malacca and surrounding islands

Based in Sumatra (modern Indonesia), ruled Malay Peninsula, Java, and neighboring islands

Dominated India-China trade routes through maritime control

Defeated by Rajendra I's naval expedition around 1025 CE

Strategic Importance

Srivijaya was a thalassocracy (sea-based empire) that controlled the world's most important maritime trade route. The Strait of Malacca between Sumatra and Malay Peninsula was the only practical shipping lane connecting the Indian Ocean with the South China Sea.

- Southern Malay Peninsula
## Extended Control
- Parts of Java
- Bangka-Belitung Islands
- Southern Thailand
## Trade Control
- Strait of Malacca

- India-China shipping routes

Why Cholas Attacked Srivijaya

Trade Disruption: Srivijaya was charging high tolls and restricting Chola merchants' access to Chinese markets

Economic Competition: Both empires wanted control over lucrative spice trade and China trade

Strategic Chokepoint: Whoever controlled the Strait of Malacca controlled Asia's maritime commerce

Commercial Intelligence: Chola merchants provided Rajendra I with detailed knowledge of Srivijaya's ports and defenses

Strategic Location

Srivijaya controlled the Strait of Malacca — the essential gateway between Indian and Pacific Oceans

Exam traps

Don't locate Srivijaya in India — it was based in Sumatra (Indonesia)

Malay Peninsula was part of Srivijaya, but capital was in Sumatra

Srivijaya was maritime power, not land-based like most Indian kingdoms

Strait of Malacca (not Strait of Hormuz) was Srivijaya's key strategic asset

Chola Naval Supremacy

Ancient And Medieval History

Chola Naval Power: India's Greatest Maritime Empire

Must know

Cholas built ancient India's most powerful navy under Rajaraja I and Rajendra I

Controlled Bay of Bengal and projected power to Southeast Asia and Sri Lanka

Only Indian dynasty to conduct successful overseas military campaigns

Good to know

Naval power supported extensive Indian Ocean trade network

The Chola navy was revolutionary for medieval India. Most Indian kingdoms focused on land armies, but Cholas developed shipbuilding technology, naval tactics, and maritime logistics that allowed them to fight thousands of kilometers from home.

What Made Chola Navy Unique

Geographic Advantage: Long Coromandel Coast provided natural harbors and shipbuilding timber

Merchant Support: Wealthy Tamil merchant guilds funded naval expeditions for trade protection

Technical Innovation: Developed large warships capable of ocean voyages with soldiers and supplies

Intelligence Network: Chola merchants in Southeast Asia provided military intelligence

Administrative System: Created naval districts with dedicated shipyards and admirals

Exam traps

Cholas were the naval power — don't confuse with land-focused Rashtrakutas or Pallavas

Both Rajaraja I and Rajendra I were naval rulers, but Rajendra I conducted the Srivijaya campaign

Chola navy dominated Bay of Bengal, not Arabian Sea (that was secondary)

Sri Lanka was conquered first, Southeast Asia came later under Rajendra I

- Eastern Deccan
- Sri Lanka

- Northern Karnataka
- Gujarat
## Kakatiya Territory
- Telangana
- Eastern Andhra Pradesh
- Warangal region
## Hoysala Territory
- Southern Karnataka
- Parts of Tamil Nadu
- Mysore plateau

Why These Rulers Didn't Conduct Naval Campaigns

Amoghavarsha: Rashtrakuta power was based in inland Deccan — focused on land control and trade routes

Prataparudra: Kakatiya kingdom faced constant Delhi Sultanate pressure — defensive warfare dominated

Vishnuvardhana: Hoysala territory was landlocked Karnataka — no significant coastal access

Geographic Limitation: Only Cholas had both the coastal base and merchant network for naval expeditions

Historical Context

While all these rulers were powerful in their regions, naval expeditions required specific conditions: coastal territory, maritime trade interests, shipbuilding capability, and merchant support. Only the Cholas combined all these factors successfully.

Exam traps

Amoghavarsha I was a great Rashtrakuta ruler but never conducted naval campaigns

Prataparudra is famous for defending against Delhi Sultanate, not overseas expeditions

Vishnuvardhana fought land battles against Cholas, but didn't have naval power

Don't confuse different Vishunuvardanas — this refers to Hoysala Vishnuvardhana (12th century)
