Why were mansabdars expected to maintain twenty-horses for every ten cavalrymen?

1. Introduction to the Mansabdari System (basic)

Welcome to your first step in mastering the Mughal administration! To understand how a vast empire like the Mughals functioned, we must start with the Mansabdari System. Introduced by Emperor Akbar, this wasn't just a military arrangement; it was the steel frame of the empire, combining civil and military officials into a single, unified service History, class XI (Tamilnadu state board 2024 ed.), The Mughal Empire, p.206. The word 'Mansab' literally means a rank or position, and every officer of the state was a Mansabdar.

The genius of this system lay in its two-fold ranking mechanism, which determined an officer’s status and responsibilities:

Feature	Zat Rank	Sawar Rank
Definition	The personal rank and status of the officer.	The military obligation (number of cavalrymen).
Determines	Salary and position in the court hierarchy.	The actual number of horses and troops maintained.

A fascinating detail often discussed is the 'Dah-Bisti' (ten-twenty) rule. To ensure the army remained mobile and effective, a Mansabdar was often required to maintain twenty horses for every ten cavalrymen. This 2:1 ratio was crucial because horses would get exhausted during long marches or injured in battle. Having fresh mounts allowed the Mughal cavalry to strike with speed and sustain long campaigns. To prevent corruption and ensure these troops actually existed, the state performed regular inspections and used Dag (branding of horses) to identify state-approved mounts Exploring Society:India and Beyond, Social Science, Class VIII. NCERT (Revised ed 2025), Reshaping India’s Political Map, p.54.

Finally, remember that the Mansabdari system was highly inclusive. While it began with Central Asian and Persian nobles, it eventually evolved into a composite nobility including Rajputs, Marathas, and Indian Muslims (Shaikhzadas) History, class XI (Tamilnadu state board 2024 ed.), The Mughal Empire, p.214. Most Mansabdars were paid through Jagirs (land revenue assignments), making them vital links between the central government and the local agrarian economy.

2. Revenue Assignments: The Jagirdari System (basic)

To understand the Mughal Empire's stability, we must look at how it sustained its massive bureaucracy. The **Jagirdari system** was the financial backbone of the Mansabdari system. While some officials were paid in cash (**Naqdi**), the majority received their salaries through **Jagirs**—temporary assignments of land revenue from specific territories THEMES IN INDIAN HISTORY PART II, History CLASS XII (NCERT 2025 ed.), Peasants, Zamindars and the State, p.214. It is crucial to remember that a Jagirdar did not own the land; they only held the right to collect the revenue (Mal) that would otherwise go to the state, effectively acting as the Emperor's representative in that region History, class XI (Tamilnadu state board 2024 ed.), The Mughal Empire, p.207.

The system was designed with checks and balances to prevent officials from becoming too powerful. Two key features ensured central control:

• Periodic Transfers: Jagirdars were moved every few years to prevent them from developing local roots or permanent power bases THEMES IN INDIAN HISTORY PART II, History CLASS XII (NCERT 2025 ed.), Peasants, Zamindars and the State, p.214.
• Non-Hereditary Nature: A Jagir was not a family inheritance. Upon the death of a Mansabdar, the land was resumed by the state (**Escheat**), and the accounts were settled History, class XI (Tamilnadu state board 2024 ed.), The Mughal Empire, p.207.

Towards the later years of the empire, particularly under Aurangzeb, the system faced a severe Jagirdari Crisis. This was a state of bejagiri (landlessness), where the number of officials increased so rapidly that there wasn't enough productive land to assign. This led to 'inflated' revenue records, where the official paper value of a Jagir was much higher than what could actually be collected from the exhausted peasantry Rajiv Ahir, A Brief History of Modern India (2019 ed.), India on the Eve of British Conquest, p.69.

Feature	Jagirdar (Imperial Official)	Zamindar (Local Landed Gentry)
Nature of Right	Right to collect revenue in lieu of salary.	Hereditary right to a share of the produce.
Location	Transferred across the empire periodically.	Stationary; rooted in their ancestral lands.

3. Economic Pillars: The Zabt and Dahshala Systems (intermediate)

To understand the Mughal Empire's longevity, we must look at its financial backbone: the land revenue system. Before Akbar, revenue was often collected through simple crop-sharing (where the state took a physical portion of the harvest), which was unpredictable and prone to corruption. To bring stability and professionalize the treasury, Akbar’s revenue minister, Raja Todar Mal, an expert in revenue affairs, introduced a series of transformative reforms History, class XI (Tamilnadu state board 2024 ed.), The Mughal Empire, p.206. At the heart of these reforms was the Zabt System. Under this system, the administration moved away from guesswork and toward scientific precision. Land was physically measured using standardized units, and the productivity of the soil was determined. Instead of taking a fluctuating share of the actual grain, the government fixed money revenue rates on each unit of area based on the specific crops being cultivated History, class XI (Tamilnadu state board 2024 ed.), The Mughal Empire, p.215. This required farmers to sell their surplus in the market to obtain the cash needed for taxes, which in turn stimulated the growth of a market economy and trade. Building upon the Zabt, the Dahshala System (introduced around 1580) was the final evolution of this economic pillar. The name comes from 'Dah', meaning ten. To prevent the state's income from swinging wildly due to a single bad monsoon or a sudden price drop, the government calculated the average produce and average prices of various crops over the preceding ten years. One-third of this average produce was fixed as the state’s share, but it was collected in cash. This provided the Mughal state with a highly predictable budget and gave farmers a clearer idea of their tax liabilities in advance.

Feature	Traditional Crop Sharing	Zabt & Dahshala Systems
Payment Mode	Usually physical grain (Kind)	Fixed Cash (Money)
Basis of Tax	Actual harvest of that specific year	10-year average of produce and prices
Administrative Effort	Low (simple division at harvest)	High (required measurement and record-keeping)
Predictability	Very low for the state treasury	Very high; allowed for better long-term planning

4. Preventing Military Fraud: Dag and Chehra (intermediate)

The efficiency of the Mansabdari system relied on the integrity of the officers (mansabdars) to maintain the troops they were paid for. However, in a decentralized system where officers were paid via land grants (jagirs), there was a high risk of corruption. A mansabdar might present 'ghost soldiers' or hire temporary laborers and borrowed horses only during the day of inspection. To combat this, Akbar institutionalized two rigorous verification methods originally used by Alauddin Khalji: Dag and Chehra. Exploring Society: India and Beyond, Class VIII, Reshaping India’s Political Map, p.54 mentions that regular inspections were essential to ensure compliance with these state requirements.
The Dag system involved the branding of horses with a royal mark to ensure that the same horse was not presented by multiple mansabdars or replaced by an inferior breed. Complementing this was Chehra (also known as Huliya), which was a detailed descriptive roll of every soldier, documenting their physical features, complexion, and identifying marks to prevent the substitution of trained troopers with untrained substitutes. These measures ensured that the Mughal state got exactly what it paid for in terms of military personnel and equipment.
Beyond preventing fraud, the Mughals followed a specific military logic known as the Dah-Bisti (ten-twenty) rule. This regulation required a mansabdar to maintain a ratio of twenty horses for every ten cavalrymen. You might wonder why a 2:1 ratio was necessary. The Mughal army was built on the mobility of its cavalry; horses, unlike humans, tire quickly during long marches or intense combat. By maintaining two horses per trooper, the army ensured that a soldier always had a fresh mount available if his primary horse was exhausted, injured, or killed. This surplus was the secret behind the rapid operational readiness of the Mughal forces.

5. System Evolution: Du-aspa Sih-aspa and Month-Scales (exam-level)

As the Mughal Empire expanded, the Mansabdari system designed by Akbar faced new challenges—specifically the need for greater military mobility and the growing gap between theoretical revenue and actual collections. To address these, Akbar’s successors, Jahangir and Shah Jahan, introduced sophisticated modifications that refined the empire's administrative and military machinery.

Under Akbar, the military logic was centered on the Dah-Bisti (ten-twenty) rule. This required every 10 cavalrymen to maintain 20 horses. The reason was purely practical: long marches and intense warfare exhausted horses faster than men. Having a 2:1 horse-to-trooper ratio ensured that a soldier always had a fresh mount, maintaining the operational readiness of the Mughal strike force. While Akbar established this foundation, his successors had to deal with the rising costs of the Deccan wars and the inflation of ranks History, class XI (Tamilnadu state board 2024 ed.), The Mughal Empire, p.208.

Jahangir introduced the Du-aspa Sih-aspa system. This was a clever way to increase the military strength of the empire without raising an officer’s Zat (personal rank/status).

• Du-aspa: Troopers with two horses.
• Sih-aspa: Troopers with three horses.

By granting this status, the Emperor could double or triple the number of horses a Mansabdar maintained for a specific campaign (especially against rivals like Malik Ambar in the Deccan) without the administrative burden of increasing the officer's personal pay or overall rank in the court hierarchy History, class XI (Tamilnadu state board 2024 ed.), The Mughal Empire, p.208.

Shah Jahan later tackled a growing fiscal crisis with the Month-Scales (Mahana). There was often a massive difference between the Jama (estimated revenue of a land grant) and the Hasil (the actual amount collected). When the actual collection fell short, Mansabdars could no longer afford to maintain the required number of troops. Shah Jahan solved this by scaling the military obligations to the actual income. If a Jagir (land grant) only yielded 50% of its estimated revenue, it was termed a "6-month scale" Jagir, and the Mansabdar was allowed to maintain a proportionally smaller number of troops while still keeping his official rank History, class XI (Tamilnadu state board 2024 ed.), The Mughal Empire, p.209.

Innovation	Introduced By	Core Purpose
Du-aspa Sih-aspa	Jahangir	Increase military strength (horses) without increasing Zat rank.
Month-Scales	Shah Jahan	Balance military obligations with actual revenue collection (Hasil).

6. Mughal Cavalry Logistics: The Dah-Bisti Rule (exam-level)

To understand the Dah-Bisti rule, we must first appreciate that the Mughal military's greatest strength was its cavalry. Whether it was Babur’s victory at Panipat or Akbar’s expansion across the Deccan, the speed and striking power of horse-mounted soldiers were decisive History, class XI (Tamilnadu state board 2024 ed.), The Mughal Empire, p.220. However, maintaining a horse in the harsh Indian climate during long military campaigns is a logistical nightmare. A horse that gallops all day cannot fight effectively the next morning. To solve this, Akbar formalised the Dah-Bisti (literally 'Ten-Twenty') rule within the Mansabdari system.

The Dah-Bisti rule required a Mansabdar to maintain a strict ratio of twenty horses for every ten cavalrymen (troopers). This 2:1 ratio was not a mere bureaucratic whim; it was a sophisticated logistical strategy. In the Sawar rank of a Mansabdar, which determined the actual number of horsemen he had to maintain History, class XI (Tamilnadu state board 2024 ed.), The Mughal Empire, p.206, this rule ensured that:

• Mobility: Troopers could switch to fresh mounts during long marches, preventing animal exhaustion.
• Resilience: If a horse was killed or injured in battle, the trooper had an immediate replacement available, keeping the unit at full strength.
• Standardization: It prevented the army from being bogged down by soldiers whose single horses had grown weak or lame.

Because the state paid the Mansabdar based on these numbers, there was a high risk of corruption. A Mansabdar might try to save money by keeping fewer horses than required. To prevent this, the Mughal administration used Dag (branding of horses) and Chehra (descriptive rolls of soldiers) to verify that the 2:1 ratio was physically present during inspections. This level of detail turned the Mughal military from a loose collection of feudal levies into a disciplined, centralized machine History, class XI (Tamilnadu state board 2024 ed.), The Mughal Empire, p.206.

7. Solving the Original PYQ (exam-level)

Now that you have mastered the foundational structure of the Mansabdari system—specifically the distinction between Zat (personal rank) and Sawar (cavalry strength)—this question asks you to connect those building blocks to the functional logistics of Mughal warfare. The core concept here is the Dah-Bisti (ten-twenty) rule introduced by Akbar. You have learned that the Mughal Empire’s power was built on a highly mobile strike force; this specific ratio was the mechanical gear that allowed that mobility to be sustained across the vast Indian subcontinent without the army's momentum being halted by animal exhaustion or combat losses.

To arrive at the correct answer, think like a military strategist: if a trooper's horse collapses during a grueling summer march or is hamstrung in the opening charge of a battle, that soldier immediately becomes a liability. By mandating twenty horses for every ten men, the state ensured that every trooper had a fresh mount for rest during marches and immediate replacements in times of war. This strategic redundancy is why Option (C) is the correct choice; it highlights the practical necessity of maintaining operational readiness in the field, a detail meticulously documented in The Army of the Indian Moghuls by William Irvine.

UPSC often uses distractors that sound plausible but fail on closer inspection of administrative logic. Option (A) is a 'prestige trap'—while the cavalry was the elite wing of the army, administrative ratios were driven by utility, not vanity. Option (B) suggests a clever way to avoid salary increases, but in reality, the Mansabdar's pay (received via Jagirs) was already calculated to cover the high cost of maintaining these extra mounts. Finally, Option (D) focuses on the mortality of imported horses; while it is true that horses were imported from Central Asia, the 2:1 ratio was a universal tactical requirement for campaigning, not just a response to animal health. Always look for the tactical objective when faced with military administration questions.
