What internal weaknesses made Later Mughals vulnerable to Nadir Shah?
Of course. Here is a conceptual explanation of the internal weaknesses of the Later Mughals that led to their vulnerability against Nadir Shah, tailored for a UPSC aspirant.
Direct Answer
The Later Mughal Empire's vulnerability to Nadir Shah's invasion in 1739 was not a sudden event but the culmination of deep-seated internal decay. The primary weaknesses were: a succession of weak and incompetent rulers after Aurangzeb, the rise of powerful, self-serving noble factions (like the Irani and Turani groups) who paralysed the central administration, a severe economic crisis rooted in the Jagirdari and Mansabdari systems, and a depleted military that had lost its discipline and technological edge. These factors created a power vacuum at the centre, leaving the empire fragmented and incapable of mounting a unified defence against a determined external aggressor.
Background
The death of Aurangzeb in 1707 marked the beginning of the end for the mighty Mughal Empire. The rulers who followed, known as the "Later Mughals," presided over a period of rapid political disintegration. While the empire's frontiers were shrinking, its internal structure was rotting from within. By the 1730s, the Mughal Emperor, Muhammad Shah (reigned 1719-1748), known as 'Rangila' for his hedonistic lifestyle, was emperor only in name. Real power was wielded by competing factions of nobles at court. It was into this hollowed-out empire that the Persian ruler, Nadir Shah, marched, seeking to plunder its famed wealth.
Core Explanation
The vulnerability of the Mughal state can be broken down into four interconnected weaknesses:
-
Political Instability and Weak Rulership: The absence of a fixed law of succession (primogeniture) led to bloody wars of succession after every emperor's death. This drained the treasury and eliminated able princes. Rulers like Muhammad Shah were more interested in arts and leisure than in administration or military preparedness. They became puppets in the hands of powerful nobles, who often acted as kingmakers.
-
Factionalism Among the Nobility: The court was divided into powerful, mutually hostile factions, primarily the Iranis (Shia), Turanis (Sunni of Central Asian origin), Afghans, and Hindustanis (Indian Muslims). Key figures like Sa'adat Khan (founder of Awadh) and Nizam-ul-Mulk (founder of Hyderabad) were more focused on carving out their own semi-independent states than on defending the empire. During Nadir Shah's invasion, this factionalism was on full display. Instead of uniting, the nobles intrigued against each other, with some even secretly negotiating with Nadir Shah to undermine their rivals.
-
Economic and Administrative Collapse: The twin pillars of Mughal administration, the Mansabdari (ranking) and Jagirdari (land grant) systems, were in a state of crisis.
- Jagirdari Crisis: There was a shortage of productive jagirs (land assignments) to grant to the growing number of nobles (mansabdars). This led to intense competition and corruption. Nobles tried to extract the maximum revenue from their short-term jagirs, oppressing the peasantry and destroying the agricultural economy.
- Empty Treasury: Constant warfare, lavish lifestyles of the emperors, and the breakdown of revenue collection from newly autonomous provinces (like Bengal and Awadh) left the central treasury empty. The empire could not afford to pay its soldiers or maintain its infrastructure.
-
Military Degeneration: The Mughal army, once a formidable force, had become weak and inefficient.
- It was a non-national, mercenary army, with soldiers loyal to their immediate commander (the noble who paid them) rather than the Emperor.
- Discipline was lax, and training was neglected.
- Military technology and tactics had stagnated, while Nadir Shah's army was a modern, disciplined force equipped with superior firearms and drilled in swift cavalry manoeuvres.
| Feature | Mughal Army (under Muhammad Shah) | Nadir Shah's Army |
|---|---|---|
| Leadership | Divided; nobles competing for glory. | Unified under a single, brilliant commander. |
| Discipline | Lax; more of a disorderly armed mob. | Strict, professional, and battle-hardened. |
| Tactics | Outdated; reliant on massed elephants and cavalry. | Modern; effective use of light artillery and cavalry. |
| Motivation | Low; irregular pay, loyalty to individual nobles. | High; promise of plunder and loyalty to Nadir Shah. |
Why It Matters
Nadir Shah's invasion was a death blow to the prestige and power of the Mughal Empire. The Battle of Karnal (24 February 1739), where a massive Mughal army was defeated in under three hours, exposed the empire's hollowness to the world. The subsequent sack of Delhi led to an unimaginable massacre and the plunder of immense wealth, including the Peacock Throne and the Koh-i-Noor diamond. This event:
- Destroyed Imperial Prestige: The Emperor was shown to be powerless to protect his own capital.
- Accelerated Political Fragmentation: It emboldened provincial governors and Maratha chiefs to assert their independence more forcefully.
- Paved the Way for European Powers: The demonstration of the Mughal Empire's weakness created a power vacuum that the British and French East India Companies would eventually exploit. The road to the Battle of Plassey (1757) was paved at the Battle of Karnal (1739).
Timeline of Decline
- 1707: Death of Aurangzeb; war of succession begins.
- 1713-1719: Reign of Farrukhsiyar, dominated by the Sayyid Brothers ("kingmakers").
- 1719-1748: Reign of Muhammad Shah 'Rangila'.
- 1724: Nizam-ul-Mulk establishes a semi-independent state in Hyderabad.
- 1737: Marathas under Baji Rao I raid the outskirts of Delhi, exposing Mughal weakness.
- 1739: Nadir Shah invades, defeats the Mughals at the Battle of Karnal, and sacks Delhi.
UPSC Angle
For the Civil Services Examination, examiners are not looking for a simple narrative. They expect you to:
- Analyse Causality: Connect the dots between political, economic, and military factors. Don't just list them; explain how weak rulers led to noble factionalism, which in turn caused the Jagirdari crisis and military neglect.
- Identify Turning Points: Frame Nadir Shah's invasion not as a cause of Mughal decline, but as a stark symptom and an accelerator of a long-term process.
- Link to Broader Themes: Connect the event to the larger theme of the "18th-Century Debate" (was it an age of darkness or regional dynamism?) and the rise of successor states and European powers. Your answer should demonstrate that the fall of the central Mughal authority created opportunities for others, including the British East India Company.
- Use Specifics: Mentioning Muhammad Shah 'Rangila', the Battle of Karnal, the Peacock Throne, and key nobles like Nizam-ul-Mulk and Sa'adat Khan adds weight and credibility to your analysis.
