Criticism / Historical Opinions on the Battle of Plassey
This part is extra reading, only for understanding basis. So can be skipped if having time limitations.
1. “A Battle of Betrayal, Not Bravery”
- Many historians argue that the Battle of Plassey was not a great military victory, but rather a political conspiracy.
- Treachery by Mir Jafar, Rai Durlabh, and others ensured British victory without a major fight.
- Robert Clive himself admitted that more was achieved through negotiation than on the battlefield.
2. A Turning Point Through Corruption
- The British bribed Indian elites and traders to betray the Nawab.
- The Jagat Seths (bankers) and other Indian merchants played a decisive role in financing British interests.
- Reflects how internal divisions and greed among Indian elites facilitated colonization.
3. Plassey as the Genesis of Corporate Exploitation
- Seen by many as the first step in the transformation of the East India Company from a trading body to a colonial power.
- Historians like Romila Thapar and R.C. Dutt have criticized how a private trading company used deceit and manipulation to conquer a sovereign Indian state.
- Led to loot and drain of wealth from Bengal, causing economic decline.
4. Indian Nationalist View
- Nationalist historians (like Bipin Chandra) argue that Plassey marked the beginning of national subjugation.
- Emphasized that foreign rule was established through Indian disunity and betrayal.
- Used as a cautionary tale in later freedom movements to emphasize unity and resistance.
5. Plassey: Not a Full-Scale War
- From a military standpoint, the battle was brief (only a few hours) and lacked any large-scale combat.
- British army had only around 3,000 troops, yet won due to political manipulation.
- Hence, often not regarded as a ‘real battle’ in the conventional sense.
6. Criticism of Robert Clive
- Clive is sometimes credited as a military genius, but his methods involved bribery, misinformation, and secret deals.
- His post-battle enrichment led to charges of corruption in Britain; he was investigated by Parliament (though acquitted).
- Seen as the embodiment of early colonial exploitation.
Concluding View:
- “The Battle of Plassey was won not on the battlefield, but in the secret chambers of conspirators.” – This perspective reminds us that colonial conquest often began through diplomacy, betrayal, and manipulation, not just military might.
