1. Harshavardhana and the Pushyabhuti Dynasty (basic)
After the decline of the great Gupta Empire, northern India fragmented into several smaller kingdoms. Amidst this political vacuum, the Pushyabhuti Dynasty (also known as the Vardhana dynasty) emerged as a dominant force. Initially based in Thanesar (near modern-day Haryana), the dynasty's foundation was laid by Pushyabhuti, who had served as a military general under the Guptas. However, it was Prabhakara Vardhana who truly elevated the family’s status by successfully defending against the Huns and Gurjaras, expanding his influence toward Malwa and Gujarat History, class XI (Tamilnadu state board 2024 ed.), Harsha and Rise of Regional Kingdoms, p.105.
The transition of power to Harshavardhana (606–647 CE) was born out of a family tragedy. His elder brother, Rajavardhana, was treacherously murdered by Sasanka, the Gauda ruler of Bengal. At the young age of 16, Harsha ascended the throne of Thanesar. Recognizing the vulnerability of isolated small kingdoms, he sought to unify northern India. A pivotal moment in his reign was the union of Thanesar with the kingdom of Kanauj (the Maukhari capital), where he was invited to rule after the death of his brother-in-law. Consequently, Harsha shifted his capital from Thanesar to Kanauj to better manage his growing empire and address security threats from the northwest History, class XI (Tamilnadu state board 2024 ed.), Harsha and Rise of Regional Kingdoms, p.105.
Harsha’s reign is particularly well-documented because of the Chinese traveler Hiuen Tsang (Xuanzang), the "Prince of Pilgrims," who spent years at Harsha's court and the University of Nalanda. His travelogue, Si-Yu-Ki, provides a vivid account of the social and religious life of the era, including Harsha's grand quinquennial assemblies at Prayag. While Harsha was a formidable conqueror in the North, his southward expansion was famously halted at the Narmada River by the Chalukya king, Pulikesin II, who thereafter assumed the title of "Parameswara" History, class XI (Tamilnadu state board 2024 ed.), Harsha and Rise of Regional Kingdoms, p.106.
580–605 CE — Reign of Prabhakara Vardhana; rise of Pushyabhuti power.
606 CE — Accession of Harshavardhana following the murder of Rajavardhana.
606–647 CE — Harsha unifies Thanesar and Kanauj; shifts capital to Kanauj.
~630 CE — Harsha is defeated by Pulikesin II of the Chalukya dynasty.
Key Takeaway Harshavardhana unified northern India by merging the kingdoms of Thanesar and Kanauj, marking a transition from fragmented regional rule to a centralized authority that was eventually checked only by the Deccan powers.

2. Regional Contemporaries: Chalukyas and Pallavas (intermediate)
While King Harshavardhana was consolidating his power in North India during the 7th century, two powerful dynasties were locked in a fierce struggle for supremacy in the South: the
Chalukyas of Badami and the
Pallavas of Kanchi. This era marks a significant shift in Indian history, as the political center of gravity moved toward the Deccan and the far South. The Chalukyas, led by their greatest ruler
Pulikesin II, controlled the Deccan plateau. Pulikesin II is famously remembered for halting Harsha’s southward expansion at the Narmada River, an achievement for which he assumed the title
'Parameswara' History , class XI (Tamilnadu state board 2024 ed.), Harsha and Rise of Regional Kingdoms, p.106.
The relationship between the Chalukyas and the Pallavas was defined by a long-standing conflict over the fertile land between the Krishna and Tungabhadra rivers. This 'tit-for-tat' warfare saw cities being sacked and titles being swapped as trophies of war. For instance, after Pulikesin II defeated the Pallava king Mahendravarman I, the latter's successor, Narasimhavarman I, retaliated by capturing the Chalukya capital, Vatapi. To commemorate this, Narasimhavarman I took the title 'Vatapikonda' (Conqueror of Vatapi). We know these details through rich epigraphical evidence, such as the Aihole inscription (written by the poet Ravikirti) and the Kuram Copper Plates of the Pallavas History , class XI (Tamilnadu state board 2024 ed.), Cultural Development in South India, p.118.
Culturally, this period was a 'Golden Age' for the South. The Chalukyas were pioneers in structural temple architecture (like those at Pattadakal), while the Pallavas are immortalized by the rock-cut rathas of Mahabalipuram. Interestingly, while Sanskrit remained the language of the elite and of pillar inscriptions, local languages were beginning to assert their identity; for example, a 7th-century inscription at Badami describes Kannada as the 'local Prakrit' or the language of the common people History , class XI (Tamilnadu state board 2024 ed.), Cultural Development in South India, p.120.

3. Foreign Travellers as Historical Sources (basic)
To understand the political and social landscape of ancient and medieval India, we often look beyond local inscriptions to the accounts of
foreign travellers. These individuals acted as 'ethnographers' of their time, recording details about governance, religious practices, and societal norms that local texts sometimes omitted as 'common knowledge.' Between the 5th and 7th centuries CE, a wave of
Chinese Buddhist pilgrims ventured to India, driven by a deep reverence for the land of the Buddha, which they respectfully referred to as
Tianzhu Exploring Society: India and Beyond, Social Science-Class VI, India, That Is Bharat, p.83. Their primary goals were to visit sacred sites, study under Indian scholars, and collect original Sanskrit manuscripts to translate back in China
THEMES IN INDIAN HISTORY PART I, History CLASS XII, Thinkers, Beliefs and Buildings, p.86.
The two most influential figures in this tradition were Faxian and Xuanzang. Faxian arrived in the early 5th century during the Gupta era, providing us with a window into a period of great cultural and scientific creativity Exploring Society: India and Beyond, Social Science-Class VII, The Gupta Era: An Age of Tireless Creativity, p.153. Two centuries later, in the 7th century, Xuanzang (often called the 'Prince of Pilgrims') arrived during the reign of King Harshavardhana. Xuanzang’s accounts are exceptionally detailed; he spent five years studying at the University of Nalanda and was a guest of honor at Harsha’s great assemblies at Prayag, where the King distributed wealth to scholars and the poor History, class XI (Tamilnadu state board 2024 ed.), Harsha and Rise of Regional Kingdoms, p.109.
What makes Xuanzang a unique historical source is the geographical breadth of his travels. Unlike many who stayed within the Gangetic plains, he travelled to the southern kingdoms and even to the far east of India. He visited the kingdom of Kamarupa (modern-day Assam) at the personal invitation of King Kumar Bhaskar Varma. His travelogue, the Si-Yu-Ki, serves as a vital chronological anchor for historians, linking the courts of North India (Harsha) with those of the Northeast (Bhaskar Varma) and the South History, class XI (Tamilnadu state board 2024 ed.), Harsha and Rise of Regional Kingdoms, p.109.

4. Socio-Religious Life: Nalanda and the Assemblies (intermediate)
During the 7th century CE, the socio-religious landscape of North India was dominated by the patronage of
King Harshavardhana and the intellectual brilliance of
Nalanda University. Nalanda was not merely a monastery but a renowned
Mahavihara (large Buddhist monastery) and an international center of learning that attracted scholars from China, Japan, Tibet, and Southeast Asia
History, class XI (Tamilnadu state board 2024 ed.), The Guptas, p.100. It flourished initially under the Guptas in the 5th century and reached its zenith under Harsha’s reign, hosting nearly 10,000 students who studied a wide range of subjects, from Buddhist philosophy to Vedic literature.
The university's reputation was upheld by a galaxy of brilliant scholars. During the famous visit of the Chinese pilgrim Hiuen Tsang (Xuanzang), the university was headed by Shilabhadra, a respected scholar who is believed to have hailed from Assam (Kamarupa) History, class XI (Tamilnadu state board 2024 ed.), Harsha and Rise of Regional Kingdoms, p.111. Other luminaries like Dharmapala and Jayasena provided the intellectual rigor that made Nalanda a global academic destination. This era also saw the tradition of grand Religious Assemblies. Harsha organized a massive assembly at Kanauj to honor Hiuen Tsang and the Mahayana sect of Buddhism, followed by the Quinquennial (five-yearly) Assembly at Prayag, where the King famously distributed his accumulated wealth among the monks, scholars, and the poor.
To understand the timeline of these interactions, we must distinguish between the various Chinese pilgrims who chronicled Indian life:
| Pilgrim |
Period |
Contemporary Ruler |
Primary Focus |
| Fa-Hien |
5th Century CE |
Chandragupta II (Gupta) |
Buddhist sites and Gupta administration |
| Hiuen Tsang |
7th Century CE |
Harshavardhana |
Nalanda, Harsha's Assemblies, and regional kings like Bhaskar Varma |
| I-tsing |
Late 7th Century CE |
Post-Harsha Era |
Monastic rules and practices |
These assemblies and the university served as a bridge between the political power of the Pushyabhuti dynasty and the socio-religious aspirations of the era. The presence of Kumar Bhaskar Varma (the King of Kamarupa/Assam) at Harsha's assemblies, alongside Hiuen Tsang, highlights the diplomatic and cultural unity that existed despite the rise of regional kingdoms History, class XI (Tamilnadu state board 2024 ed.), Harsha and Rise of Regional Kingdoms, p.110.
Key Takeaway Nalanda was the intellectual heart of the 7th century, where global scholarship met royal patronage through Harsha’s grand religious assemblies and the leadership of scholars like Shilabhadra.

5. The Kingdom of Kamarupa and Bhaskar Varma (exam-level)
The
Kingdom of Kamarupa, located in the Brahmaputra Valley of modern-day
Assam, emerged as a significant political entity during the 7th century CE under the
Varman Dynasty. Its most illustrious ruler was
Bhaskar Varma (also known as Kumar Bhaskar Varma). At a time when North India was witnessing the rise of
Harshavardhana, Kamarupa played a pivotal role in the regional power struggle. Historically, Kamarupa was also referred to as
Pragjyotisha, and its rulers traced their lineage to the mythical Naraka.
History, class XI (Tamilnadu state board 2024 ed.), Harsha and Rise of Regional Kingdoms, p.106
The defining feature of Bhaskar Varma's reign was his strategic alliance with Harshavardhana. Both rulers shared a common adversary: Sasanka, the ruler of the Gauda Empire (modern Bengal). Sasanka was a formidable rival who had assassinated Harsha's brother, Rajyavardhana. By forming a pincer alliance, Harsha and Bhaskar Varma effectively neutralized Sasanka's influence. This partnership allowed Harsha to consolidate his hold over Northern India and eventually subjugate regions like Magadha and Odra after Sasanka's death. History, class XI (Tamilnadu state board 2024 ed.), Harsha and Rise of Regional Kingdoms, p.106
Beyond warfare, Bhaskar Varma was a great patron of learning and diplomacy. One of the most famous historical accounts of Kamarupa comes from the Chinese pilgrim Hiuen Tsang (Xuanzang). While Hiuen Tsang was studying at the University of Nalanda, Bhaskar Varma invited him to visit his capital. Such was the prestige of the pilgrim that Harsha later requested Hiuen Tsang's presence at his own court in Kanauj and the great assembly at Prayag. This interaction highlights that Kamarupa was not an isolated frontier but a vital part of the cultural and political fabric of 7th-century India. Exploring Society: India and Beyond, Social Science-Class VI, NCERT (Revised ed 2025), Chapter 5: India, That Is Bharat, p.83
Early 7th Century CE — Accession of Bhaskar Varma to the throne of Kamarupa.
c. 606 CE — Alliance formed between Harsha and Bhaskar Varma against Sasanka of Gauda.
c. 642-643 CE — Hiuen Tsang visits the court of Kamarupa before joining Harsha at Kanauj.
Key Takeaway The alliance between Bhaskar Varma of Kamarupa and Harshavardhana was a masterstroke of 7th-century diplomacy that ensured the stability of their respective kingdoms against the expansionist Gauda Empire.

6. Hiuen Tsang (Xuanzang): The 'Prince of Pilgrims' (exam-level)
When we look at the 7th century CE, one figure stands out as our most reliable 'eye-witness' to the political and social landscape of North India: Hiuen Tsang (also known as Xuanzang). Often celebrated as the 'Prince of Pilgrims', he was a Chinese Buddhist monk who embarked on a perilous journey to India to collect authentic Buddhist scriptures and visit the holy sites of his faith. Born in China in 612 CE, he became a monk at twenty and eventually spent about fifteen years traveling throughout the Indian subcontinent History, Class XI (Tamilnadu state board 2024 ed.), Harsha and Rise of Regional Kingdoms, p.109.
Hiuen Tsang’s arrival coincided with the reign of King Harshavardhana. Their relationship was not merely that of a king and a visitor, but of a patron and a scholar. Hiuen Tsang spent five years studying at the University of Nalanda, the premier center of learning in the ancient world. His travelogue, Si-Yu-Ki (Records of the Western World), remains a goldmine for historians, providing intricate details about Harsha's administration and the religious climate of the time History, Class XI (Tamilnadu state board 2024 ed.), Harsha and Rise of Regional Kingdoms, p.105. He famously attended Harsha's Mahamoksha Parishad — a grand quinquennial assembly at Prayag (modern-day Prayagraj) — where the King distributed his accumulated wealth among monks, scholars, and the poor History, Class XI (Tamilnadu state board 2024 ed.), Harsha and Rise of Regional Kingdoms, p.109.
One of the most unique aspects of Hiuen Tsang's journey was his diplomatic footprint. Unlike Fa-Hien, who visited during the Gupta period (5th century), or I-tsing, who arrived after Harsha’s death, Hiuen Tsang is the only major Chinese pilgrim recorded to have visited the courts of both Harsha and Kumar Bhaskar Varma of Kamarupa (modern-day Assam). In fact, it was at Bhaskar Varma's insistent invitation that Hiuen Tsang visited Kamarupa before Harsha requested his presence at Kanauj, highlighting the interconnected political network of 7th-century India.
Early 5th Century: Fa-Hien visits India (Gupta Era - Chandra Gupta II).
629–645 CE: Hiuen Tsang travels in India (Harsha Era).
Late 7th Century: I-tsing visits India (Post-Harsha Era).
Remember the Order: First His Info — Fa-Hien (Guptas) → Hiuen Tsang (Harsha) → I-tsing (Later).
Key Takeaway Hiuen Tsang is the primary historical link between the reigns of Harshavardhana and Bhaskar Varma, providing the most detailed account of 7th-century Indian politics and the Nalanda tradition through his work, Si-Yu-Ki.

7. Solving the Original PYQ (exam-level)
Now that you have mastered the political landscape of 7th-century India, this question brings your conceptual building blocks together. You have studied the rise of the Pushyabhuti dynasty under Harshavardhana and the contemporary Kamarupa kingdom (modern-day Assam) ruled by Kumar Bhaskar Varma. This question tests your ability to link these two rulers through a common external observer. In UPSC preparation, it is vital to remember that Harsha's reign was a golden era for diplomatic and religious exchanges, particularly through the influx of Buddhist scholars who documented the socio-political climate of the time.
To arrive at the correct answer, Hiuen Tsang (also known as Xuanzang), you must recall the specific sequence of his travels. As detailed in History, class XI (Tamilnadu state board 2024 ed.), he was not just a guest of Harsha at the Prayag assemblies and Nalanda, but he also spent significant time in Kamarupa at the personal invitation of Bhaskar Varma. The reasoning cue here is the timeline: you are looking for the pilgrim whose presence in India (approx. 630–645 CE) perfectly overlaps with the peak of Harsha’s power. His travelogue, Si-Yu-Ki, serves as the definitive primary source for the interactions between these two distinct regional powers.
UPSC frequently uses "Timeline Traps" and "Distractors" to test your precision. Fa-Hien is a common trap; while he was a famous Chinese traveler, he visited during the Gupta period (5th century CE), roughly 200 years before Harsha. I-tsing, on the other hand, arrived in the late 7th century after Harsha's death, making him chronologically impossible for this question. Finally, Sun Shuyun represents a "Modern Distractor"—she is a contemporary author who retraced these ancient steps, not an ancient traveler herself. As highlighted in Exploring Society: India and Beyond, Class VI NCERT (Revised ed 2025), only Hiuen Tsang connects the courts of both Harsha and Bhaskar Varma, making him the only historically accurate choice.
