Assertion (A) : During the time of Akbar, for every ten cavalrymen, the mansabdars had to maintain twenty horses. Reason (R) : Horses had to be rested while on march and replacements were necessary in times of war.

1. Mughal Central Administration: The Pillars of Power (basic)

At the peak of its glory, the Mughal Empire was more than just a collection of territories; it was a highly centralized and uniform administrative machine that integrated diverse regions from Afghanistan to the deep south (History, class XI (Tamilnadu state board 2024 ed.), The Mughal Empire, p.199). This stability was not accidental. It was built upon a sophisticated bureaucratic structure, primarily the Mansabdari system, which served as the empire's steel frame. This system ensured that the central authority, led by the Emperor, maintained a tight grip on both the military and the nobility across vast distances.

To ensure the military remained the "envy of its contemporaries" (Modern India, Bipin Chandra, History class XII (NCERT 1982 ed.), The Decline of the Mughal Empire, p.1), Akbar introduced rigorous technical standards. One such critical regulation was the Dah-Bisti (Ten-Twenty) rule. This rule mandated that for every ten sawars (cavalrymen), a Mansabdar (official) had to maintain twenty horses. In simpler terms, the state required a 2:1 ratio of horses to troopers. This wasn't a bureaucratic whim; it was a strategic necessity for a mobile empire.

The logic behind this 2:1 ratio addressed the practical realities of medieval warfare and logistics:

• Rest and Rotation: Horses, unlike soldiers, succumb quickly to the fatigue of long marches. Having spare horses allowed for rotation, ensuring the animals remained healthy.
• Combat Readiness: In the heat of battle, a horse was a large target. A sawar without a horse was useless. Spare horses provided immediate replacements for those killed or injured.
• Speed and Mobility: The ability to move the army quickly across the Indian subcontinent was the secret to Mughal dominance. Fresh horses meant the cavalry could maintain a rapid pace without waiting for exhausted animals to recover.

2. Genesis of the Mansabdari System (basic)

To understand the Mughal Empire's strength, we must look at the Mansabdari system, the structural backbone of their administration. Introduced by Akbar, this wasn't just a military arrangement but a unique civil-military bureaucracy where every officer held a specific rank called a mansab. According to the Ain-i-Akbari written by Abul Fazl, this system allowed the Emperor to assemble a massive, professional army at short notice without the burden of maintaining a single, massive permanent central force. Exploring Society:India and Beyond, Class VIII NCERT (Revised ed 2025), Reshaping India’s Political Map, p.54. Officials, known as Mansabdars, were categorized into a dual ranking system: Zat and Sawar.

The distinction between these two ranks is fundamental to how the Mughal state functioned:

Rank Component	What it Determined
Zat	Determined the personal status, position in the court hierarchy, and the salary of the officer.
Sawar	Indicated the specific number of cavalrymen (horsemen) the officer was required to maintain for service.

History, Class XI (Tamilnadu state board 2024 ed.), The Mughal Empire, p.206

A critical operational feature of this system was the Dah-Bisti (ten-twenty) rule. Akbar realized that for a cavalry-based army to be effective across the vast Indian landscape, speed and endurance were paramount. Therefore, the rule required a ratio of two horses for every single sawar (cavalryman). This ensured that during long marches or intense battles, a soldier always had a fresh mount available if his horse became fatigued, injured, or was killed in action. This focus on mobility and combat readiness is what made the Mughal military machine so formidable during its peak.

3. The Economic Base: Land Revenue Systems (intermediate)

The Mughal Empire’s survival and grandeur were rooted in its ability to extract a stable surplus from the land. This was achieved through a sophisticated land revenue system, primarily orchestrated by Raja Todar Mal, Akbar’s finance minister. Moving away from the arbitrary and often chaotic collection methods of earlier eras, Todar Mal introduced a system based on scientific measurement and historical data. As noted in Exploring Society: India and Beyond, Reshaping India’s Political Map, p.55, he initiated detailed surveys of crop yields and prices, ensuring that the state's demands were grounded in reality rather than mere guesswork. At the heart of these reforms was the Zabt or Dahshala system. Instead of fixing revenue every year, the administration calculated the average yield and the average price of various crops over the preceding ten years. One-third of this average was generally fixed as the state’s share, usually payable in cash. To make this work, the empire underwent a massive land-mapping exercise using a uniform measurement unit called the Gaz-i-Ilahi. Land was further classified into four categories based on its continuity of cultivation: Polaj (cultivated annually), Parauti (left fallow occasionally), Chachar (fallow for 3-4 years), and Banjar (uncultivated for 5 years or more). This categorization ensured that farmers were not unfairly taxed for land that wasn't producing. The actual collection on the ground relied on a powerful class of intermediaries known as Zamindars. These were often members of dominant local clans or castes who held hereditary rights over the land. According to History Class XI (TN), The Mughal Empire, p.214, the Ain-i-Akbari details how these Zamindars — ranging from Rajputs to local Muslim elites — maintained their own armed retainers and held the right to evict peasants if rent was not paid. This system created a complex social hierarchy where the state, the intermediary Zamindar, and the peasant were bound together in a rigid, yet functioning, economic cycle.

4. Provincial and Local Governance (intermediate)

The Mughal Empire was a masterclass in organized decentralization. To manage a vast territory effectively, Akbar divided the empire into Subahs (provinces), which were the primary units of provincial governance. By the end of his reign, there were 15 such provinces, each functioning like a miniature version of the central government. This structure ensured that while the Emperor held ultimate power, the day-to-day administration was handled by specialized officials at the local level. Exploring Society: India and Beyond, Reshaping India’s Political Map, p.53 At the heart of provincial governance was a brilliant system of checks and balances. The Subahdar (Provincial Governor) was responsible for political and military security, but he did not have total control. The Diwan, who handled provincial finances and revenue, was independent of the Subahdar and reported directly to the central Diwan in the capital. This separation of power prevented any single official from becoming a threat to the Emperor's authority. Other key provincial officers included the Bakshi (military paymaster) and the Sadr (judicial and religious head). Exploring Society: India and Beyond, Reshaping India’s Political Map, p.53 Moving deeper into the administrative layers, the Subahs were divided into smaller units to bring the government closer to the people:

Level	Unit Name	Key Official(s)
Province	Subah	Subahdar (Executive), Diwan (Finance)
District	Sarkar	Faujdar (Law & Order), Amalguzar (Revenue)
Sub-district	Pargana / Mahal	Shiqdar (Executive), Amil (Revenue)
Village	Gram	Muqaddam (Headman), Patwari (Accountant)

At the most local level—the village—the Mughals largely allowed traditional self-governance to continue. The village panchayat and hereditary officials like the Muqaddam (headman) and Patwari (accountant) managed local disputes and tax records. These local figures were vital links between the imperial state and the peasantry. THEMES IN INDIAN HISTORY PART II, Peasants, Zamindars and the State, p.218

5. The Jagirdari System and its Linkages (intermediate)

To understand the Jagirdari system, we must first view it as the financial heartbeat of the Mughal Empire. While the Mansabdari system determined a person's rank and status, the Jagirdari system was the mechanism through which they were actually paid. As noted in Themes in Indian History Part II, Peasants, Zamindars and the State, p.214, the Mughal state was a military-cum-bureaucratic apparatus. To sustain this, the Emperor assigned Jagirs—specific territories from which a Mansabdar (the Jagirdar) was authorized to collect land revenue equivalent to his sanctioned salary.

There were two primary ways a Mansabdar could be compensated. While some were Naqdi (paid in cash from the royal treasury), the vast majority were Jagirdars who collected revenue directly from the land. A crucial administrative safeguard was that these assignments were not hereditary. Upon the death of a Mansabdar, the land was immediately resumed by the state, a practice known as escheat. Furthermore, to prevent officers from developing local roots and challenging imperial authority, Jagirdars were transferred periodically, usually every three to four years (History Class XI (Tamil Nadu State Board), The Mughal Empire, p.207).

At the military level, the revenue from these Jagirs was used to maintain the required number of troops and horses. A fascinating rule implemented during Akbar's reign was the Dah-Bisti (ten-twenty) rule. This mandated a ratio of two horses for every single sawar (cavalryman). Why this specific 10:20 ratio? In the vast landscape of the Mughal Empire, military campaigns involved long, grueling marches. Horses would frequently suffer from fatigue, injury, or death. By maintaining spare horses, the Mughal cavalry ensured combat readiness and mobility, allowing a rider to switch to a fresh mount and keep the army moving at a swift pace.

Feature	Description
Nature of Assignment	Right to collect revenue, not ownership of land.
Dah-Bisti Rule	Requirement to maintain 2 horses per cavalryman (10:20 ratio).
Permanence	Non-hereditary and subject to frequent transfers.

6. Military Discipline: Dagh and Chehra (exam-level)

To maintain the vast Mughal Empire, Akbar realized that a mere numerical count of soldiers was not enough; military discipline and quality control were essential. Two of the most critical innovations to prevent corruption and ensure combat readiness were the systems of Dagh (branding) and Chehra (descriptive rolls). Before these were strictly enforced, many Mansabdars (officers) would cheat the state by presenting 'ghost' soldiers or borrowing horses from neighbors only for the day of inspection. To stop this, Akbar mandated that every horse be branded with a royal mark (Dagh) and every soldier have a detailed physical description recorded (Chehra or Ahrar), covering features like height, complexion, and visible scars. This ensured that the same soldier or horse wasn't counted twice across different regiments Exploring Society: India and Beyond, Reshaping India’s Political Map, p.54.
Another pillar of this military efficiency was the Dah-Bisti (ten-twenty) rule. This rule required a Mansabdar to maintain a ratio of two horses for every single cavalryman (Sawar). In the context of the Mughal Sawar rank, which determined the size of the cavalry contingent History Class XI (Tamilnadu State Board), The Mughal Empire, p.206, this ratio was a stroke of genius. It recognized the harsh realities of medieval warfare: horses would often tire, fall ill, or be killed during long-distance campaigns. By having spare horses, the Mughal cavalry could maintain high mobility and speed, allowing a rider to switch to a fresh mount during a march or battle without slowing down the entire army.

System	Primary Purpose	Mechanism
Dagh	Horse Identification	Physical branding of animals to prevent substitution of inferior horses.
Chehra	Soldier Verification	Written description of a soldier's physical features to prevent proxy recruitment.
Dah-Bisti	Combat Mobility	A 10:20 ratio ensuring every soldier had access to replacement horses for fatigue and loss.

7. The Dah-Bisti Rule and Military Ratios (exam-level)

To understand the Mughal military's efficiency, we must look beyond just the number of soldiers to the logistical standards they maintained. Under Akbar’s Mansabdari system, an officer's rank was split into Zat (personal rank) and Sawar (the number of cavalrymen he had to maintain) History, class XI (Tamilnadu state board 2024 ed.), The Mughal Empire, p.206. However, a soldier is only as good as his mobility. This led to the implementation of the Dah-Bisti (Ten-Twenty) Rule, which mandated that for every 10 sawars (cavalrymen), a mansabdar was required to maintain 20 horses. This established a strict 1:2 ratio between men and mounts.

The logic behind this ratio was purely practical. During the long, grueling campaigns that expanded the empire from Kabul to the Deccan, horses frequently suffered from exhaustion, lameness, or battle injuries. By requiring two horses per soldier, the Mughal administration ensured:

• Continuous Mobility: Soldiers could rotate horses during long marches to prevent the animals from breaking down.
• Combat Readiness: If a horse was killed in battle, the sawar remained an effective cavalryman by switching to his spare mount (known as a remount).
• Speed: It allowed the Mughal light cavalry to move at a pace that often surprised their enemies.

To ensure these standards weren't just on paper, the state conducted regular inspections and branding of horses (dagh) Exploring Society:India and Beyond, Class VIII . NCERT(Revised ed 2025), Reshaping India’s Political Map, p.54. If a mansabdar failed to present the required number of healthy horses, his salary or jagir assignments could be docked. This system transformed the Mughal army into a highly professionalized machine where every soldier was backed by the necessary biological "fuel" — the horse — to sustain an empire.

8. Solving the Original PYQ (exam-level)

Now that you have mastered the foundational components of the Mansabdari system, specifically the distinction between Zat (personal status) and Sawar (military obligation), this question brings those building blocks into sharp focus. The core concept at play here is the Dah-Bisti (ten-twenty) rule, which represents the practical application of military logistics under Akbar. As we discussed in our study of Mughal administration, the efficiency of the imperial army relied not just on the number of men, but on their sustained mobility across the diverse terrain of the Indian subcontinent.

To arrive at the correct answer, (A) Both A and R are true, and R is the correct explanation of A, we must evaluate the logical link between the administrative ratio and the reality of 16th-century warfare. Assertion (A) identifies the 1:2 ratio (10 sawars to 20 horses) mandated by Akbar to ensure military vigor. Reason (R) provides the functional "why": horses are biological assets prone to fatigue, heatstroke, and injury. By ensuring two horses per cavalryman, Akbar guaranteed that a soldier could rotate mounts during a long march or replace a fallen steed in the heat of battle. Because the logistical need for endurance directly dictates the administrative requirement for extra livestock, the Reason serves as the perfect justification for the Assertion.

UPSC often uses Option (B) as a trap for students who recognize individual facts but miss the causal link. You might be tempted to view these as two unrelated statements, but in the context of Ain-i-Akbari, every regulation was a solution to a specific battlefield problem. Options (C) and (D) are easily avoided if you remember that Akbar’s reforms were designed to prevent the military decay seen in earlier periods; a 1:1 ratio would have left the cavalry vulnerable and slow. Always ask yourself: "Does the second statement explain the 'logistical logic' of the first?" If it does, Option A is your target.
