Growth and Development of Buddhism in Odisha: A Post-Graduate Level Analysis
I. Introduction
The growth of Buddhism in Odisha represents a crucial phase in the historical and cultural evolution of eastern India. Strategically situated on the eastern coast, Odisha (ancient Kalinga) became a vibrant center for Buddhist learning, practice, and dissemination. Its trajectory—from early patronage in the Mauryan era to the rise of tantric Vajrayāna schools—demonstrates a complex interplay of socio-political, religious, and transregional dynamics.

II. The Kalinga War and Ashokan Transformation
The Kalinga War (c. 261 BCE) marks a pivotal event not only in the history of Odisha but also in the expansion of Buddhism. The devastation caused by the war led Emperor Ashoka to adopt the Buddhist faith and propagate Dhamma as a state policy. Rock Edicts found at Dhauli (south of Bhubaneswar) provide direct evidence of Ashoka’s remorse and his appeal to non-violence and moral governance.
Dhauli Edict Highlights:
- Promotion of religious tolerance.
- Renunciation of violence (Ahimsa).
- Emphasis on public welfare and ethical conduct (Dhamma Vijaya).
III. Archaeological and Textual Evidence of Growth
A. Early Monastic Establishments (1st century BCE – 3rd century CE)
- Lalitgiri: Earliest evidence of Buddhist occupation; Theravāda tradition; discovery of relic casket with potential bodily remains of the Buddha.
- Langudi Hills: Ashokan stupas and inscriptions indicating early Buddhist presence.
B. Flourishing of Mahāyāna and Vajrayāna Traditions (5th–12th century CE)
- Sites like Ratnagiri, Udayagiri, and Lalitgiri developed into major monastic universities.
- Influence of Tantric Buddhism (Vajrayāna), as seen in the iconography of Tara, Manjusri, and Heruka.
- Linkages with the Pāla Empire of Bengal, which supported Buddhist institutions in eastern India.
C. Evidence of an Ancient University – Pushpagiri
- Mentioned in Chinese traveler Xuanzang’s accounts.
- Believed to be located within the Langudi–Lalitgiri complex, comparable to Nalanda and Vikramashila.
IV. Maritime Buddhism and Transregional Influence
Odisha’s extensive maritime trade via ports like Tamralipta and Kalingapatnam enabled the spread of Buddhism to:
- Sri Lanka
- Myanmar
- Thailand
- Indonesia (Srivijaya)
Monks and traders from Odisha played a vital role in the Sanskritization and Indianization of Southeast Asia.
V. Decline of Buddhism in Odisha
Causes:
- Rise of Hindu devotional (bhakti) movements, especially Shaivism and Vaishnavism.
- Decline of royal patronage after the 12th century.
- Destruction and neglect of monastic sites during Turko-Afghan invasions.
- Gradual assimilation of Buddhist deities into the Hindu pantheon (e.g., Tara with Durga).
VI. Modern Rediscovery and Revival
- Rediscovery of Buddhist sites by the Archaeological Survey of India (ASI) in the 20th century.
- Systematic excavation of Ratnagiri, Udayagiri, and Lalitgiri revealed monastic architecture, sculptures, and inscriptions.
- Promotion of the “Diamond Triangle” as a part of India’s Buddhist tourism circuit.
VII. Conclusion
The growth of Buddhism in Odisha illustrates a unique synthesis of religious transformation, statecraft, and transregional connectivity. From Ashoka’s remorse to the development of Vajrayāna thought, Odisha served not only as a crucible of Buddhist philosophy but also as a bridge between the Indian subcontinent and Southeast Asia. Its legacy, although diminished by historical circumstances, continues to offer rich material for historical, archaeological, and philosophical inquiry.
