1. The Delhi Sultanate: Mongol Invasions & Tughlaq Policy (basic)
To understand the stability of the
Delhi Sultanate, one must look at its Northwest frontier. For over a century, the Sultanate faced the persistent threat of
Mongol invasions. While the Mongols under Genghis Khan were known for total devastation—literally 'ploughing over' cities that resisted, as seen in Central Asian hubs like Nishapur
Themes in World History, Class XI (NCERT), Nomadic Empires, p.65—their relationship with India was a mix of military confrontation and diplomatic maneuvering. By the time of the
Tughlaq Dynasty, the Mongol threat had shifted from the unified empire of Genghis Khan to the
Chagatai Khanate of Transoxiana.
Muhammad bin Tughlaq (r. 1325–1351) is often remembered for his eccentric experiments, but he was also a capable military commander. Around 1326–27, the Mongol ruler Tarmashirin Khan led a massive force into India, reaching as far as Meerut near Delhi. Muhammad bin Tughlaq managed to effectively repulse this army, ensuring the capital's safety History, Class XI (TN State Board), Advent of Arabs and Turks, p.144. Historical accounts suggest he either defeated them in battle or used diplomatic 'gifts' (tribute) to encourage their retreat. This proactive defense was a hallmark of his early reign, contrasting sharply with the later decline of the dynasty.
The situation turned catastrophic for the Tughlaqs toward the end of the 14th century. During the reign of Nasir-uddin Muhammad Shah, the last Tughlaq ruler, the Central Asian conqueror Timur (Tamerlane) invaded in 1398. Claiming a blood link to Genghis Khan, Timur's forces ransacked Delhi with almost no opposition, causing the Sultan to flee the city History, Class XI (TN State Board), Advent of Arabs and Turks, p.147. Timur’s invasion didn't just loot wealth; he forcibly took Indian artisans—masons and stone cutters—back to his capital, Samarkand, to build his monuments. This invasion effectively broke the back of the Tughlaq central authority, paving the way for the Sayyid and Lodi dynasties.
c. 1326-27 — Tarmashirin Khan (Chagatai Mongol) invades; repulsed by Muhammad bin Tughlaq.
1394-1412 — Reign of Nasir-uddin Muhammad Shah, the final Tughlaq ruler.
1398 — Timur invades and sacks Delhi, leading to the collapse of Tughlaq power.
Key Takeaway While early Tughlaq rulers like Muhammad bin Tughlaq successfully checked Mongol incursions (like those of Tarmashirin Khan), the devastating 1398 invasion by Timur during the reign of Nasir-uddin Muhammad Shah signaled the end of Tughlaq dominance.

2. The Rise of Vijayanagar and Foreign Chronicles (basic)
The 14th century was a period of immense political flux in India. As the power of the Delhi Sultanate began to wane in the south, two great powers emerged: the
Bahmani Sultanate and the
Vijayanagar Empire. Founded in 1336 by the Sangama brothers,
Harihara and Bukka, on the south bank of the River Tungabhadra, Vijayanagar (the 'City of Victory') grew from a regional principality into a massive bulwark of South Indian culture and administration
History, class XI (Tamilnadu state board 2024 ed.), Bahmani and Vijayanagar Kingdoms, p.186. This empire was ruled by four successive dynasties: the Sangama, Saluva, Tuluva, and Aravidu. Its most famous ruler,
Krishnadeva Raya of the Tuluva dynasty, not only expanded the empire's borders but also transformed the capital, Hampi, into a world-renowned center of art and architecture, known specifically for the
Dravida style featuring tall
Raya Gopurams (gateways) and
Kalyanamandapams (marriage halls)
History, class XI (Tamilnadu state board 2024 ed.), Bahmani and Vijayanagar Kingdoms, p.186.
Much of what we know about the grandeur of Vijayanagar comes from
Foreign Chronicles. These travelers were often merchants or envoys who recorded the socio-political life of the era with fascinating detail. For instance,
Nicolo Conti (an Italian) and
Abdur Razak (a Persian envoy) provided early descriptions of the city's massive fortifications and wealth
History, class XI (Tamilnadu state board 2024 ed.), Bahmani and Vijayanagar Kingdoms, p.186. Another critical figure was
Fernao Nuniz, a Portuguese horse trader who visited during the reign of Achyuta Deva Raya. His chronicles are invaluable for understanding the administrative structure and the status of women in the empire. These foreign accounts act as a bridge, connecting the archaeological ruins of Hampi to the lived reality of a bustling medieval metropolis.
To understand the rise of Vijayanagar, one must also look at the broader Indian landscape of the time. While Vijayanagar was consolidating the south, other regions saw unique developments. In the north, the Mongol ruler
Tarmashirin Khan invaded India during the reign of Muhammad bin Tughlaq (c. 1326-27), illustrating the external pressures the Sultanate faced. Meanwhile, in
Kashmir, the ruler
Zainul Abidin (affectionately known as
Budshah or the 'Great King') was busy building a sophisticated network of canals to modernize agriculture, showing that the spirit of 'Great Builders' was not limited to the south. In the west, Portuguese factors like
Farnao Martinz Evangelho were negotiating trade interests in places like
Champaner (Gujarat), highlighting how European influence was beginning to seep into the Indian subcontinent through its coastal trade routes.
Key Takeaway The Vijayanagar Empire served as a pinnacle of South Indian medieval glory, whose history is uniquely reconstructed through the intersection of grand Dravidian architecture and the detailed descriptive accounts of foreign travelers like Fernao Nuniz.

3. Regional Sultanates: The 'Akbar of Kashmir' (intermediate)
In the medieval history of the Kashmir Sultanate, the reign of Sultan Zain-ul-Abidin (1420–1470) stands out as a golden age of stability and cultural synthesis. Often referred to by the locals as 'Budshah' (The Great King), he earned the title 'Akbar of Kashmir' because his liberal and administrative policies predated the Mughal Emperor Akbar’s similar reforms by nearly a century. He ascended the throne at a time when the region was reeling from the orthodox and often harsh policies of his father, Sikandar Shah (Butshikan). Zain-ul-Abidin completely reversed this direction by practicing religious tolerance, recalling the Hindus who had fled the valley, and even abolishing the Jizya (tax on non-Muslims) and banning cow slaughter to respect the sentiments of his subjects.
One of his most enduring legacies was his focus on infrastructure and public works. He recognized that the valley’s prosperity depended on agriculture, leading him to construct an extensive network of canals to irrigate the land. This historical emphasis on water management paved the way for the sophisticated irrigation systems seen in modern India, where canals remain a perennial source of water regulated by weirs and sluice gates Indian Economy, Nitin Singhania (2nd ed.), Irrigation in India, p.360. His engineering marvels, such as the Zainalank (an artificial island in Wular Lake) and the canal known as Lachman Kuhl, transformed the agricultural landscape of Kashmir.
Beyond economics, the Sultan was a profound patron of arts and literature. He was a polyglot who knew Sanskrit, Persian, and Tibetan. Under his patronage, the famous historical chronicle of Kashmir, Kalhana’s Rajatarangini, was continued by Jonaraja and Srivara, and many Sanskrit texts were translated into Persian. He also introduced new crafts to the valley, such as silk-weaving and paper-making, by bringing experts from Samarkand, which laid the foundation for Kashmir’s world-renowned handicraft industry. While the political status of Jammu and Kashmir has evolved significantly in modern times Politics in India since Independence, NCERT, Regional Aspirations, p.119, the cultural and administrative footprint of Zain-ul-Abidin remains central to the region's historical identity.
Key Takeaway Sultan Zain-ul-Abidin is called the 'Akbar of Kashmir' because he pioneered religious pluralism, abolished Jizya, and revolutionized the valley’s economy through massive canal irrigation projects and the introduction of new industries.

4. Portuguese Expansion and Factors in India (intermediate)
The Portuguese were the first Europeans to establish a direct sea route to India, but their impact went far beyond simple trade. While Vasco da Gama’s arrival in 1498 opened the door, it was
Alfonso de Albuquerque who is considered the
real founder of Portuguese power in the East. He realized that to dominate the Indian Ocean, Portugal needed to control strategic 'choke points'—entrances to the sea like Hormuz, Malacca, and Aden. By capturing
Goa from the Sultan of Bijapur in 1510, he established a permanent territorial base that served as the capital of the
Estado Português da India for centuries
Rajiv Ahir, Advent of the Europeans in India, p.26.
The expansion continued northward through clever diplomacy and military pressure. A significant milestone occurred during the governorship of
Nino da Cunha, who shifted the Portuguese headquarters from Cochin to Goa in 1530. He successfully exploited the conflict between the Mughal Emperor Humayun and
Bahadur Shah of Gujarat. In exchange for Portuguese support, Bahadur Shah ceded the island of
Bassein in 1534 and later allowed them a base in
Diu. However, this alliance was short-lived; relations soured, leading to the infamous death of Bahadur Shah during a negotiation on a Portuguese ship in 1537
Rajiv Ahir, Advent of the Europeans in India, p.27, 56.
To maintain their monopoly, the Portuguese introduced the
Cartaz System—a permit system requiring all non-Portuguese ships to pay for protection. Their dominance was bolstered by superior naval technology and the fact that their rivals in the Red Sea lacked the timber necessary to build comparable fleets
Rajiv Ahir, Advent of the Europeans in India, p.26. Despite these advantages, several factors eventually led to their decline, which are summarized below:
| Factor | Description |
|---|
| Geopolitical Shifts | The discovery of Brazil diverted Portuguese resources and interest toward the West. |
| Religious Policy | The Inquisition in Goa and aggressive Jesuit missionary activities alienated local Hindu and Muslim populations. |
| Rising Competition | The arrival of the more organized and well-funded Dutch and English East India Companies challenged their monopoly. |
| Local Powers | The emergence of the Marathas as powerful neighbors and the consolidation of the Mughal Empire restricted Portuguese land expansion. |

5. Medieval Public Works and Infrastructure (exam-level)
In medieval India, infrastructure was the backbone of state stability. While many associate this era with grand tombs and forts, the most visionary rulers focused on
public works—specifically irrigation—to secure agricultural revenue and public welfare. The
Tughlaq Dynasty stands out as a pioneer in this regard.
Firuz Shah Tughlaq is often credited with laying the foundation of a canal-based irrigation system in North India, digging major canals from the
Sutlej to Hansi and another from the
Yamuna History, class XI (Tamilnadu state board 2024 ed.), p.147. These projects weren't just for farming; they helped establish new towns and supported the military logistics of the Sultanate.
Moving to regional kingdoms,
Zainul Abidin (the 15th-century ruler of Kashmir, fondly called
'Budshah' or the Great Sultan) transformed the landscape of the valley. He was remarkably ahead of his time, commissioning a sophisticated network of canals that reclaimed marshy lands for cultivation. His focus on
water management and public welfare earned him a reputation as the 'Akbar of Kashmir.' Similarly, in the South, the
Vijayanagar Empire utilized massive storage tanks and canals to sustain its dry hinterlands. We know much about the socio-political impact of these works through accounts of foreign visitors like
Fernao Nuniz, a Portuguese horse trader who chronicled the empire's prosperity during the 16th century.
These medieval efforts transitioned into the modern era as the
perennial canal system. Unlike inundation canals that rely on seasonal floods, perennial canals use weirs and sluice gates to maintain water flow year-round
Indian Economy, Nitin Singhania, p.360. Many iconic modern canals, such as the
Western Yamuna Canal, actually trace their origins back to the engineering works initiated by medieval Sultans, illustrating a direct link between historical public works and contemporary Indian agriculture
Indian Economy, Nitin Singhania, p.359.
Key Takeaway Medieval public works, particularly the irrigation canals of Firuz Shah Tughlaq and Zainul Abidin, were strategic state investments that converted arid regions into economic hubs, forming the blueprint for India's modern canal network.

7. Solving the Original PYQ (exam-level)
This question serves as a perfect synthesis of the administrative reforms, foreign incursions, and global interactions you have just studied across the Delhi Sultanate, the Vijayanagar Empire, and regional kingdoms. By linking Muhammad bin Tughlaq’s turbulent reign with the Mongol threat of Tarmashirin Khan, and connecting the socio-economic prosperity of Kashmir under Zainul Abidin (the 'Budshah'), you can see how individual rulers shaped their territories. As detailed in Satish Chandra's History of Medieval India, these cross-regional developments occurred as India became increasingly integrated into global trade networks, evidenced by the arrival of Portuguese figures such as the chronicler Nuniz and the trade factor Farnao Martinz Evangelho.
To arrive at the correct answer, you should apply the elimination method starting with the most recognizable 'anchors.' You likely identified Fernao Nuniz as the Portuguese horse trader who provided a detailed account of the Vijayanagar Empire (C-1). Similarly, Zainul Abidin is famously credited with transforming the Kashmir Valley through a sophisticated network of canals (D-2). These two matches alone narrow your options significantly. The final piece of the puzzle is identifying Tarmashirin Khan’s invasion as a major external challenge during the reign of Muhammad bin Tughlaq (A-4), which leads you directly to the correct answer: (C). The remaining match, Farnao Martinz Evangelho to Champaner (B-3), represents the Portuguese attempts to establish trade relations with the Sultanate of Gujarat.
UPSC often includes 'trap' associations to test the depth of your conceptual clarity. A common pitfall here is the keyword trap: a student might see 'Tughlaq' in List-I (D) and instinctively match it with 'Muhammad' in List-II (4), forgetting that Zainul Abidin’s engineering projects in Kashmir are a specific historical milestone. Another challenge is the obscurity trap, involving Farnao Martinz Evangelho. While you might not have memorized every minor Portuguese factor, by locking in the major themes of Vijayanagar and the Tughlaq Mongol policy, you can solve even the most complex 'Match the List' questions with confidence.
