When the Mughal Empire was collapsing, which of the provinces was lost in 1622 A.D., recovered in 1638 A.D. and finally lost in 1649 A.D.

1. Mughal Foreign Policy: The North-West Frontier (basic)

The North-West frontier was the most critical strategic concern for the Mughal Empire, as it served as the gateway for almost every major invasion into the Indian subcontinent, from Alexander the Great to the Mughals themselves History, class XI (Tamilnadu state board 2024 ed.), The Mughal Empire, p.199. To protect the heartland of India, the Mughals aimed to control the 'Scientific Frontier'—the line stretching from Kabul to Kandahar. While Kabul remained a stable part of the empire after Akbar's conquest History, class XI (Tamilnadu state board 2024 ed.), The Mughal Empire, p.204, Kandahar became a persistent bone of contention between the Mughals and the Safavid Empire of Persia.

Kandahar was not just a military outpost; it was a vital commercial hub for caravans traveling between India and Central Asia. The struggle for its control defines the shifts in Mughal military prestige. Under Akbar, the fort was secured in 1595, but the Mughals lost it in 1622 during Jahangir’s reign. This loss was largely due to internal instability; Prince Khurram (the future Shah Jahan) was in open rebellion and refused to lead the campaign, fearing his brothers would seize the throne in his absence History, class XI (Tamilnadu state board 2024 ed.), The Mughal Empire, p.208.

Shah Jahan eventually recovered Kandahar in 1638 through the defection of the Persian governor, Ali Mardan Khan. However, the victory was short-lived. In 1649, the Safavid ruler Shah Abbas II recaptured the province. Despite three massive, expensive expeditions led by Shah Jahan’s sons, Aurangzeb and Dara Shikoh, the Mughals failed to retake the city. This failure exposed the limitations of the Mughal artillery and siege tactics compared to the Persians.

The permanent loss of Kandahar in 1649 was a massive blow to Mughal prestige and security. It left the empire vulnerable to future incursions, eventually paving the way for the devastating 18th-century invasions by Nadir Shah and Ahmad Shah Abdali, which fundamentally broke the empire's back Rajiv Ahir, A Brief History of Modern India (2019 ed.), India on the Eve of British Conquest, p.60.

2. The Safavid Empire and Mughal Diplomacy (basic)

To understand Mughal foreign policy, we must look at their relationship with the Safavid Empire of Persia. While the two empires shared a deep cultural bond—Persian was the official language of the Mughal court and the Safavids had famously sheltered Humayun during his exile NCERT Class XII, Themes in Indian History Part II, p.221—their political relationship was defined by a fierce tug-of-war over the strategic city of Kandahar.

Kandahar was not just a city; it was the gateway to India. It sat at the intersection of major trade routes and acted as a vital military buffer against invasions from the northwest. The Mughals believed that holding Kandahar was essential for the security of Kabul and the heartland of India. Control over this outpost shifted like a pendulum between the two powers for over a century:

The final loss of Kandahar in 1649 was a turning point. It signaled the decline of Mughal military prestige and drained the imperial treasury. Furthermore, it left the northwest frontier vulnerable, a weakness that would later be exploited by invaders like Nadir Shah in the 18th century History, Class XI (Tamilnadu State Board 2024 ed.), Chapter 14, p.232.

3. Geopolitical Importance of Kandahar (intermediate)

To understand the geopolitical significance of Kandahar, we must look at it as more than just a city; it was the strategic pivot between the Mughal Empire and the Safavid Empire of Persia. Geographically, Kandahar was the gateway to the Indian subcontinent from the West. Control over this region meant control over the lucrative overland trade routes that connected India, Persia, and Central Asia. These routes were part of a vast network, similar to the historical Silk Routes, where textiles and spices from India were exchanged for precious metals and horses from the West India and the Contemporary World – II, The Making of a Global World, p.54. For the Mughals, Kandahar was the first line of defense against any Persian invasion and a vital hub for monitoring the Northwest Frontier.

The history of Kandahar in the 17th century is a classic case of how internal politics can dictate foreign policy outcomes. The city was a bone of contention that changed hands several times:

The loss of Kandahar in 1649 was a massive blow to Mughal prestige and security. It wasn't just about territory; rulers often attempted to control these routes to offer "protection for a price" and collect transit duties THEMES IN INDIAN HISTORY PART I, Kings, Farmers and Towns, p.44. By losing Kandahar, the Mughals lost their buffer zone and their grip on the vital artery of Central Asian trade, leaving the empire more vulnerable to future external pressures.

4. Internal Mughal Politics and Frontier Security (intermediate)

In the study of Mughal history, the Northwest Frontier was not just a border but a vital artery for trade and a strategic buffer against invasions from Central Asia and Persia. At the heart of this frontier stood Kandahar. Controlling Kandahar meant controlling the gateway to India. However, the history of this region serves as a stark reminder of how internal political instability can directly lead to the erosion of national security.

During the reign of Jahangir, the Mughal Empire faced a critical turning point. Kandahar, which had been secured by Akbar in 1595, became a target for the Persian Safavid ruler, Shah Abbas. In 1622, the Persians moved to recapture it. At this moment, the Mughal court was paralyzed by internal factions. Nur Jahan, Jahangir’s powerful queen, was the de facto ruler, and her attempts to promote her son-in-law, Shahryar, created deep insecurity in Prince Khurram (the future Shah Jahan) History, Class XI (Tamilnadu State Board 2024 ed.), Chapter 14: The Mughal Empire, p. 208. When ordered to lead the defense of Kandahar, Khurram feared that leaving the capital would allow his rivals to seize the throne. He chose to rebel rather than march to the frontier. This internal rebellion ensured that Kandahar was lost to the Persians in 1622, as the empire's best military resources were diverted to fight a civil war instead of a foreign invader.

The struggle for Kandahar continued under Shah Jahan. In 1638, the city was briefly recovered when the Kurdish governor, Ali Mardan Khan, defected from the Persians and handed the fort over to the Mughals History, Class XI (Tamilnadu State Board 2024 ed.), Chapter 14: The Mughal Empire, p. 209. However, this success was short-lived. By 1649, the Safavids under Shah Abbas II recaptured the province. Despite three massive and expensive military expeditions led by Shah Jahan’s sons—Aurangzeb and Dara Shikoh—the Mughals failed to win it back. This sequence of events is significant because it exposed the limits of Mughal military logistics and the rising cost of internal princely rivalries.

6. The Three Key Eras of Kandahar: 1622, 1638, and 1649 (exam-level)

To understand the Mughal Empire's Northwest frontier policy, one must look at Kandahar. Situated at the crossroads of trade and military routes, it was the ultimate strategic prize between the Mughal Empire and the Safavid (Persian) Empire. While Akbar had secured it in 1595, the 17th century saw a dramatic 'tug-of-war' defined by three pivotal years: 1622, 1638, and 1649.

The first major shift occurred in 1622 during the reign of Jahangir. The Persian King, Shah Abbas I, besieged the city at a time when the Mughal court was paralyzed by internal factionalism. Prince Khurram (the future Shah Jahan), who was the most capable general, refused to lead the relief expedition to Kandahar. He feared that his absence from the capital would allow his rivals, particularly Queen Nur Jahan, to consolidate power against him. Consequently, the leaderless Mughal defenses crumbled, and Kandahar was lost to the Persians History, Class XI (Tamil Nadu State Board), Chapter 14, p. 208.

In 1638, now as Emperor, Shah Jahan managed to recover the province without a major war. This was achieved through 'political intrigue' rather than brute force. Ali Mardan Khan, the Kurdish governor of Kandahar under the Persians, felt alienated and threatened by his own government. He decided to defect and handed the keys of the strategic fort over to the Mughals. This was a massive diplomatic victory for Shah Jahan History, Class XI (Tamil Nadu State Board), Chapter 14, p. 209.

However, the Mughal triumph was short-lived. In 1649, the Persians under Shah Abbas II launched a determined campaign and recaptured the city. This year marked a permanent turning point; despite three massive and expensive subsequent sieges led by Shah Jahan’s sons—Aurangzeb and Dara Shikoh—the Mughals could never retake the city. The loss of 1649 was final, signaling a decline in Mughal military prestige and leaving the empire's northwest frontier vulnerable.

7. Solving the Original PYQ (exam-level)

This question brings together the building blocks you have studied regarding the Mughal-Safavid rivalry and the strategic importance of the Northwest Frontier. As we discussed in our concept sessions, the control of gateway cities was not just about territory, but about controlling trade routes and demonstrating imperial prestige. The timeline provided in the question mirrors the fluctuating power of the Mughal state: the loss in 1622 occurred when internal court politics and Prince Khurram’s rebellion weakened the empire’s defense, while the 1638 recovery was a diplomatic victory facilitated by the defection of the Persian governor, Ali Mardan Khan.

To arrive at the correct answer, (D) Kandahar, you must track the sequence of events through the reigns of Jahangir and Shah Jahan. The final loss in 1649 occurred when Shah Abbas II exploited the Mughals' focus on Central Asian campaigns. Despite multiple attempts by Aurangzeb and Dara Shikoh to retake the fort, it remained outside Mughal hands, marking a definitive failure of their frontier policy as noted in History, class XI (Tamilnadu state board 2024 ed.). This pattern of gain and loss is unique to the Persian borderlands, making Kandahar the only logical fit.

UPSC often uses distractor options like Ajmer, Kashmir, or Bengal to test your geographical and political context. Ajmer was a core province and religious center that never faced foreign occupation during this era. Kashmir remained a stable Mughal retreat after its conquest by Akbar, and Bengal, while prone to internal revolts, was never a point of contention with a foreign empire like the Safavids. By recognizing that the years 1622, 1638, and 1649 specifically define the Mughal-Safavid Wars, you can confidently eliminate the internal provinces and identify the frontier outpost of Kandahar.
