1. The Twilight of the Mughals: Power Vacuum in North India (basic)
To understand the rise of regional powers in India, we must first look at the
crumbling center. For nearly two centuries, the Mughal Empire was the bedrock of Indian political life. However, after the death of Aurangzeb in 1707, this 'Great Banyan Tree' began to rot from within. While the empire technically lasted until 1857, its actual power had shrunk to a small area around Delhi by the mid-18th century
Bipin Chandra, The Decline of the Mughal Empire, p.1. This decline wasn't a sudden crash but a
gradual erosion caused by weak successors, a bankrupt treasury, and a military that had lost its discipline and morale because soldiers often went unpaid for months
Bipin Chandra, The Decline of the Mughal Empire, p.14.
The real tragedy of the 'Twilight' was the administrative paralysis. Because there was no fixed law of succession, every time an Emperor died, a bloody civil war broke out among his sons. This forced the nobility to split into warring factions—such as the Irani, Turani, and Hindustani groups—who cared more about their own influence than the health of the state Rajiv Ahir, India on the Eve of British Conquest, p.68. As the Mughal center grew 'worthless' and neglected the provinces, a power vacuum was created. Local governors (Subahdars) began to act like independent kings, and local landlords (Zamindars) openly defied central taxes.
Nature and politics both abhor a vacuum. As Delhi's grip loosened, two major forces rushed in to claim the prize of North India: the Marathas from the south and the Afghans from the northwest. By 1758, the Marathas had become so bold that they captured Punjab and expelled Ahmad Shah Abdali's agents, including his son Timur Shah. This was a direct challenge to the Afghan king’s authority. Abdali did not return to India in 1759 simply to loot; he came on a punitive expedition to avenge the Maratha 'usurpation' of his territories Rajiv Ahir, India on the Eve of British Conquest, p.60. This clash of titans, fueled by the Mughal collapse, set the stage for the definitive Third Battle of Panipat in 1761.
| Factor of Decline |
Impact on the Empire |
| Succession Wars |
Drained the treasury and created deep divisions in the nobility. |
| Weak Military |
Soldiers became mercenaries; loss of fighting spirit and discipline. |
| External Invasions |
Invasions by Nadir Shah and Abdali gave the 'death-blow' to Mughal prestige. |
Key Takeaway The Mughal decline was a systemic failure of leadership and finance that left North India leaderless, turning the region into a violent battleground between the Marathas and the Afghans.

2. The Rise of the Maratha Confederacy (basic)
The transition of the Marathas from a regional kingdom into a pan-Indian
Confederacy is one of the most significant shifts in 18th-century Indian history. While Shivaji Maharaj laid the foundation of a centralized state, it was under
Baji Rao I (1720–1740), often called the greatest of the Peshwas, that the Maratha power decentralized into a collaborative network of military chiefs
Rajiv Ahir, A Brief History of Modern India, Expansion and Consolidation of British Power in India, p.101. This system allowed the Marathas to manage vast new territories rapidly while appeasing the
Kshatriya military commanders who were sometimes wary of the growing authority of the
Brahmin Peshwas.
Under this arrangement, specific spheres of influence were assigned to prominent Maratha families. These chiefs were expected to conquer and administer their regions, but they did so in the name of the Maratha King,
Shahu History, class XI (Tamilnadu state board 2024 ed.), The Marathas, p.231. This collective was composed of five primary power centers:
- The Peshwa at Poona (the functional head)
- The Gaekwad at Baroda
- The Bhonsle at Nagpur
- The Holkars at Indore
- The Sindhias at Gwalior
To fuel this expansion, the Marathas utilized a unique dual-taxation system. They levied
Chauth (a 25% tax on revenue) and
Sardeshmukhi (an additional 10% tax) on provinces not directly under their rule
Exploring Society: India and Beyond, Social Science, Class VIII, The Rise of the Marathas, p.74. In exchange, the Marathas provided protection and promised not to interfere in internal governance. By 1740, this strategy allowed them to dominate
Malwa, Gujarat, and Bundelkhand, effectively crippling the Mughal influence in North India and setting the stage for a direct confrontation with external invaders like the Afghans
Rajiv Ahir, A Brief History of Modern India, India on the Eve of British Conquest, p.69.
Key Takeaway The Maratha Confederacy was a decentralized power-sharing arrangement that allowed individual military chiefs to expand the Empire's reach across India while remaining nominally loyal to the Maratha Chhatrapati.

3. The Persian Prelude: Nadir Shah's Invasion (1739) (intermediate)
Concept: The Persian Prelude: Nadir Shah's Invasion (1739)
4. The Maratha Intervention in Delhi Politics (intermediate)
By the mid-18th century, the Maratha Confederacy had emerged as the most potent challenge to the decaying Mughal authority. As the Mughals grew weaker, the Marathas transitioned from a regional power in the Deccan to aspiring pan-Indian emperors, possessing the strength to fill the political vacuum left by the Mughals Modern India, Bipin Chandra, Indian States and Society in the 18th Century, p.29. This expansion was not just territorial; it involved becoming the ultimate arbiters of Delhi politics. By 1752, they had entered into an informal protectorate over the Mughal Emperor, promising to protect the throne from internal and external threats in exchange for the rights to collect Chauth (tribute) from various provinces.
The turning point in Maratha-Delhi relations occurred during the late 1750s. The Marathas, under the leadership of Raghunath Rao, pushed deep into North India and Punjab. Their intervention reached a climax through two specific actions that directly challenged the interests of the Afghan ruler, Ahmad Shah Abdali:
- Expulsion of Najib-ud-Daula: In 1758, the Marathas removed Abdali’s trusted agent and Ruhela chief, Najib-ud-Daula, from his position of influence in Delhi.
- Capture of Punjab: The Marathas captured Lahore and expelled Timur Shah, the son and viceroy of Abdali. This move brought the Maratha frontier all the way to the Indus River, directly usurping Afghan sovereignty in the region.
While this expansion showcased Maratha might, it also led to their political isolation. Their aggressive policies and previous record of extracting tribute had alienated potential allies like the Jats, the Rajputs, and the Sikhs. Even the Wazir in Delhi, Imad-ul-Mulk, became a mere puppet in Maratha hands History, Tamilnadu State Board, The Marathas, p.232. This lack of a broad-based northern coalition meant that when Abdali returned in 1759 to avenge the expulsion of his son and reclaim Punjab, the Marathas were forced to face the Afghan coalition largely on their own.
1752 — Marathas become the de facto protectors of the Mughal Emperor.
1757-58 — Marathas occupy Delhi and capture Lahore/Punjab.
Oct 1759 — Ahmad Shah Abdali launches a punitive expedition to recover Punjab.
1761 — The clash culminates in the Third Battle of Panipat.
Key Takeaway The Maratha intervention in Delhi and the capture of Punjab in 1758 transformed them into the primary rivals of the Afghans, directly provoking Ahmad Shah Abdali’s invasion and the subsequent showdown at Panipat.

5. Ahmad Shah Abdali and the Durrani Empire (intermediate)
To understand the rise of the Durrani Empire, we must first look at the vacuum created by the decline of the Persians and Mughals. After the Persian ruler Nadir Shah plundered Delhi in 1739 and annexed territories west of the Indus, he was assassinated in 1747. One of his most capable military generals, Ahmad Shah Abdali, seized this opportunity to establish an independent kingdom in Afghanistan History, class XI (Tamilnadu state board 2024 ed.), Chapter 15, p.232. Abdali is often regarded as the founder of modern Afghanistan. His empire, at its peak, stretched from the Oxus River in the north to the Arabian Sea in the south, and from eastern Persia to the plains of North India.
Abdali’s relationship with India was defined by a series of invasions (eight in total between 1748 and 1767) aimed at securing wealth and consolidating his eastern borders. By the mid-1750s, the Mughal Empire was so fragile that it ceded Multan and the Punjab to him History, class XI (Tamilnadu state board 2024 ed.), Chapter 15, p.232. In 1757, Abdali captured Delhi, but rather than ruling directly, he installed Alamgir II as a puppet Emperor and appointed the Rohilla chief, Najib-ud-Daula, as his personal agent (Mir Bakhshi) to oversee Afghan interests in the heart of India Rajiv Ahir, A Brief History of Modern India (2019 ed.), Chapter 4, p.60.
The turning point for the Durrani Empire in India was the direct confrontation with the Marathas. As the Marathas expanded their influence into North India, they expelled Abdali’s agent Najib-ud-Daula from Delhi and drove his son, Timur Shah, out of Lahore in 1758. This "Maratha usurpation" of Afghan-controlled territories provoked Abdali's return in 1759 for a punitive expedition Rajiv Ahir, A Brief History of Modern India (2019 ed.), Chapter 4, p.60. This escalated into the Third Battle of Panipat (1761), where Abdali decisively defeated the Maratha confederacy. While Abdali won the battle, he did not stay to build an Indian empire; however, his victory critically weakened the Marathas, indirectly facilitating the later rise of British power.
1747 — Ahmad Shah Abdali becomes independent ruler of Afghanistan after Nadir Shah's death.
1757 — Abdali captures Delhi; recognizes Alamgir II as Emperor.
1758 — Marathas (Raghunath Rao) capture Punjab and expel Afghan agents.
1761 — Third Battle of Panipat: Abdali defeats the Marathas.
Key Takeaway Ahmad Shah Abdali transformed Afghanistan into a powerful regional state and checked Maratha expansion in North India at the Third Battle of Panipat, creating a power vacuum that shifted the trajectory of Indian history.

6. The Maratha Campaign to the Indus (1758) (exam-level)
By the mid-18th century, the Marathas had evolved from a regional power in the Deccan into the primary contenders for the mantle of the Mughal Empire. The year 1758 marked the zenith of this expansion, often romanticized in Maratha history as the realization of the "Attock to Cuttack" dream. Under the leadership of Raghunath Rao (the Peshwa’s brother) and Malhar Rao Holkar, the Maratha forces marched into North India to assert their authority over the Mughal heartland and the frontier provinces Rajiv Ahir, A Brief History of Modern India (2019 ed.), Chapter 4, p.60.
The campaign was a direct challenge to the Afghan Emperor, Ahmad Shah Abdali, who had previously installed his own administrative machinery in Delhi and the Punjab. In a series of swift military strikes, the Marathas achieved three critical objectives:
- Expulsion of Najib-ud-Daula: They removed the Rohilla chief who served as Abdali’s personal agent and Mir Bakhshi in Delhi Rajiv Ahir, A Brief History of Modern India (2019 ed.), Chapter 4, p.60.
- Capture of Punjab: The Maratha flags were hoisted over Sirhind and Lahore. They successfully pushed the Afghan frontier back toward the Indus History, class XI (Tamilnadu state board 2024 ed.), Chapter 15, p.233.
- Deposition of Timur Shah: They drove out Abdali’s son and viceroy, Timur Shah, from Lahore, effectively ending Afghan control over the region for a brief period History, class XI (Tamilnadu state board 2024 ed.), Chapter 15, p.233.
While this campaign demonstrated the sheer reach of Maratha power—extending briefly into areas like Attock and Peshawar—it also sowed the seeds of a massive conflict Exploring Society, Class VIII NCERT, Chapter 4, p.70. By uprooting Abdali’s son and his key ally, Najib-ud-Daula, the Marathas turned a territorial dispute into a personal vendetta for the Afghan ruler. This humiliation prompted Abdali to launch a massive punitive expedition in late 1759, which eventually culminated in the Third Battle of Panipat (1761). The Marathas attempted to hold the region by sending Dattaji Scindia to stabilize the Punjab, but he was eventually defeated and killed by the returning Afghan forces in 1760 History, class XI (Tamilnadu state board 2024 ed.), Chapter 15, p.233.
1757 — Abdali sacks Delhi; appoints Najib-ud-Daula as his agent and Timur Shah as Governor of Punjab.
1758 — Raghunath Rao leads the Maratha campaign; captures Lahore and expels Afghan authorities.
1759 — Abdali returns to India to avenge the deposition of his son and reclaim the Punjab.
Key Takeaway The 1758 Maratha campaign to the Indus was a strategic overreach that successfully deposed Abdali's viceroy, Timur Shah, but also directly provoked the Afghan invasion that led to the disastrous Battle of Panipat.

7. The Casus Belli: Expulsion of Timur Shah (exam-level)
To understand why the Third Battle of Panipat (1761) occurred, we must look at the Casus Belli — the specific act that makes war inevitable. By the mid-1750s, North India was a tug-of-war between the fading Mughals, the rising Marathas, and the Afghan Empire under Ahmad Shah Abdali. After his 1757 invasion, Abdali didn't just loot Delhi; he established a formal Afghan presence. He recognized Alamgir II as the Mughal Emperor but appointed his own trusted lieutenant, the Rohilla chief Najib-ud-Daula, as the Mir Bakhshi (supreme agent) to keep the Emperor in check Rajiv Ahir, A Brief History of Modern India (2019 ed.), Chapter 4, p.60. Crucially, he appointed his son, Timur Shah, as the viceroy of Lahore to govern the strategic Punjab region.
The spark was ignited in 1758 when the Marathas, led by Raghunath Rao, launched a massive northward expansion. This was not just a raid; it was a total takeover of the Afghan sphere of influence. The Marathas reached as far as Attock and Peshawar, effectively pushing the boundary of the Maratha Empire to the Indus River NCERT (Revised ed 2025), Exploring Society: India and Beyond, The Rise of the Marathas, p.70. In the process, they committed two acts that Abdali could not ignore: they expelled his supreme agent Najib-ud-Daula from Delhi and, more personally, they deposed Timur Shah from Lahore Tamil Nadu State Board, History Class XI (2024 ed.), Chapter 15, p.233.
For Abdali, the expulsion of his son was a personal and political humiliation. Punjab was a vital buffer and source of revenue for his Durrani Empire. The Maratha occupation of Lahore and Multan meant that the "Hindu Pad Padshahi" (the Maratha ideal of Hindu sovereignty) was now knocking on the doors of Afghanistan. This forced Abdali’s hand; he returned to India in October 1759 not just for loot, but for retaliation and recovery. He successfully drove the Marathas out of Punjab, leading to a series of skirmishes — including the death of Dattaji Scindia in 1760 — that eventually climaxed on the fields of Panipat Tamil Nadu State Board, History Class XI (2024 ed.), Chapter 15, p.233.
1757 — Abdali appoints Najib-ud-Daula in Delhi and Timur Shah as Viceroy of Lahore.
1758 — Raghunath Rao leads Maratha forces into Punjab, expelling Najib and deposing Timur Shah.
1759 — Abdali returns to India to avenge his son's expulsion and recover lost territories.
1761 — The Third Battle of Panipat takes place between the Marathas and the Afghan-Rohilla alliance.
Key Takeaway The immediate cause of Ahmad Shah Abdali’s 1759 invasion was the Maratha capture of Punjab and the deposition of his son, Timur Shah, which directly challenged Afghan sovereignty in North India.

8. Solving the Original PYQ (exam-level)
To solve this question, you must synthesize three concepts you’ve just studied: the decline of Mughal central authority, the Maratha expansion into North India (the Hindu Pad Padshahi), and the Durrani Empire's interests in Punjab. The building blocks come together when you realize that by 1758, the Marathas had reached the zenith of their power, appointing their own allies in Delhi and pushing into the northwest frontier. According to Rajiv Ahir's A Brief History of Modern India (SPECTRUM), this expansionist policy directly collided with Ahmad Shah Abdali’s territorial claims, as the Marathas expelled his agent Najib-ud-Daula and his viceroy Timur Shah from Lahore. This was the specific geopolitical spark that transformed a general rivalry into the 1761 confrontation.
The reasoning process hinges on identifying the immediate trigger rather than a general motive. While Abdali certainly had long-term interests in India, the catalyst for his 1759 expedition was the personal and political insult of his son, Timur Shah, being driven out of Punjab by Raghunath Rao’s forces. This makes (A) He wanted to avenge the expulsion by Marathas of his viceroy Timur Shah from Lahore the correct choice. As noted in History, class XI (Tamilnadu state board), Abdali’s return was a punitive strike to recover lost provinces and restore Afghan prestige. When you see "immediate reason" in a UPSC prompt, always look for the event that broke the status quo right before the conflict began.
UPSC often uses plausible-sounding distractors to test the depth of your timeline knowledge. Option (B) is a classic trap; while Adina Beg Khan was a key player who initially invited the Marathas to help him against the Afghans, he did not invite Abdali to invade. Option (C) refers to revenue disputes (the Chahar Mahal) which were issues in earlier invasions (like 1752), but they were not the primary cause for the Third Battle of Panipat. Finally, Option (D) describes a general strategic goal of many invaders, but it lacks the causal specificity required for an "immediate reason." Always distinguish between long-standing ambitions and immediate provocations to avoid these traps.
