Sources of Early Historic Assam History: Archaeological, Literary, Numismatic and Epigraphic Evidence – MCQs
Introduction
The history of ancient Assam, particularly the Early Historic Period, is reconstructed from a combination of archaeological remains, literary references, coins, inscriptions, copper-plate grants, sculptures, pottery, architectural remains and other material evidence. These sources are especially important because continuous historical narratives for ancient Assam are limited.
The study of these sources helps historians understand the emergence of Kamarupa, its rulers, political boundaries, religious traditions, land grants, social institutions, economic activities and cultural connections with other parts of the Indian subcontinent.
Among the most important categories of sources are:
- Archaeological sources – settlements, pottery, sculptures, temples, structural remains, tools and other excavated materials.
- Literary sources – Sanskrit texts, religious literature, accounts of foreign travellers and references in wider Indian literature.
- Numismatic sources – coins and related monetary evidence.
- Epigraphic sources – inscriptions engraved on rocks, stones, copper plates and other durable materials.
The combination of these sources is essential because no single category provides a complete picture of ancient Assam.
Archaeological Sources of Early Historic Assam
Archaeology provides direct material evidence of past human activity. Archaeological investigation may include excavation, exploration, analysis of artefacts, architectural remains, pottery, metal objects, sculptures, structural features and environmental remains.
Important archaeological evidence from Assam includes sites and objects associated with the ancient and early medieval cultural landscape of the Brahmaputra Valley and adjoining regions.
Major archaeological evidence
Ambari, in Guwahati, is an important archaeological site that has yielded structural and cultural remains. The Assam State Museum also preserves important archaeological objects from different periods.
Nagajari Khanikargaon, in Golaghat district, is particularly significant. The Assam State Museum identifies its material as belonging to the early part of the 5th century CE.
Archaeological evidence can reveal:
- Settlement patterns
- Technology
- Pottery traditions
- Religious practices
- Sculpture and artistic traditions
- Building techniques
- Trade and cultural contacts
- Changes in material culture
Archaeological excavation is particularly valuable because objects are studied in their stratigraphic and contextual position, rather than merely as isolated artefacts.
Literary Sources
Literary sources provide references to the geographical, political, religious and cultural conditions of ancient Assam.
Several categories are relevant:
1. Sanskrit Literature
Ancient and early medieval Sanskrit literature contains references to Pragjyotisha and Kamarupa. Such references have to be examined critically because literary texts may combine historical information with mythology, religious traditions and legendary narratives.
2. Epics and Puranic Literature
The Mahabharata and various Puranic traditions contain references associated with Pragjyotisha and Kamarupa.
The Kalika Purana, although considerably later than the earliest historical evidence, is especially important for understanding the religious and cultural traditions associated with Kamarupa and Kamakhya.
3. Foreign Accounts
The account of the Chinese Buddhist pilgrim Xuanzang (Hiuen-Tsang) is an important source for 7th-century Kamarupa.
Xuanzang visited Kamarupa during the reign of Bhaskaravarman. His observations provide information about the kingdom, its geography, society, religion and political connections.
Critical Use of Literary Sources
Literary evidence should not automatically be treated as literal historical fact. Historians compare literary references with archaeological, epigraphic and other evidence to determine their historical value.
Numismatic Sources
Numismatics is the systematic study of coins and related forms of currency.
Coins can provide evidence concerning:
- Rulers
- Political authority
- Economic activity
- Trade
- Religious symbols
- Artistic traditions
- Metallurgy
- Chronology
- Political and commercial connections
The value of numismatic evidence depends on the circumstances of discovery, identification, attribution, metal composition, symbols, legends, weight standards and archaeological context.
Coins must therefore be studied alongside inscriptions and archaeological evidence rather than in isolation.
The Directorate of Historical and Antiquarian Studies, Assam, maintains a collection of old coins as part of its historical holdings.
Epigraphic Sources
Epigraphy is the study of inscriptions.
Epigraphic evidence is among the most important sources for reconstructing the political and administrative history of ancient Assam.
Inscriptions may occur on:
- Rocks
- Stones
- Pillars
- Copper plates
- Temple structures
- Other durable materials
Umachal Rock Inscription
The Umachal Rock Inscription is an important early inscription of Assam. It is located on Umachal in the Nilachal hill area of Guwahati.
The inscription is written in Brahmi-derived script and refers to Maharajadhiraja Sri Surendravarman and the construction of a temple or cave shrine dedicated to Lord Balabhadra.
It is significant for the study of early Kamarupa and its rulers.
Copper-Plate Inscriptions
Copper-plate grants are especially important because they often record:
- Royal genealogies
- Land grants
- Names of rulers
- Administrative divisions
- Villages and boundaries
- Brahmanical settlements
- Religious institutions
- Social and economic arrangements
The Dubi copper plates and Nidhanpur copper-plate grant associated with Bhaskaravarman are particularly important for reconstructing the history of Kamarupa.
The Nidhanpur plates are especially valuable because they preserve information about earlier grants and royal authority.
Allahabad Pillar Inscription and Kamarupa
The Allahabad Pillar inscription of Samudragupta is an important external epigraphic source for the political geography of northeastern India.
It mentions Kamarupa and Davaka among the political entities known to the Gupta emperor.
This is significant because it provides evidence for the existence of these political formations in the 4th century CE.
The inscription should be distinguished from inscriptions actually found in Assam: it is an external source for the history of the region.
Why Multiple Sources Are Necessary
The reconstruction of ancient Assam cannot depend upon one type of evidence.
For example:
- Archaeology can reveal material culture and settlement patterns.
- Literary sources can preserve geographical, religious and cultural references.
- Coins can provide evidence of economy, authority and chronology.
- Inscriptions can provide names, titles, genealogies, land grants and administrative information.
When different sources independently support a historical conclusion, historians can establish a stronger basis for interpretation.

18. Which of the following best explains the historical importance of inscriptions?
A. They always provide complete historical narratives
B. They provide direct textual evidence from the period or context in which they were produced
C. They are useful only for studying religion
D. They contain no information about administration
Correct Answer: B. They provide direct textual evidence from the period or context in which they were produced
Explanation:
Inscriptions are valuable because they often represent contemporary or near-contemporary records. They can mention rulers, titles, genealogies, donations, places, administrative divisions and religious institutions. However, inscriptions also have limitations and must be interpreted critically rather than treated as completely neutral historical narratives.
19. Which literary tradition contains references to Pragjyotisha and Kamarupa?
A. Sanskrit literary tradition
B. Only European travel literature
C. Only Persian chronicles
D. Only modern Assamese novels
Correct Answer: A. Sanskrit literary tradition
Explanation:
References to Pragjyotisha and Kamarupa occur in Sanskrit literary and religious traditions. These include epic and Puranic materials. However, literary references must be critically assessed because mythological, religious and historical elements may be interwoven.
20. Which text is particularly associated with the religious traditions of Kamarupa and Kamakhya?
A. Kalika Purana
B. Arthashastra
C. Rajatarangini
D. Mudrarakshasa
Correct Answer: A. Kalika Purana
Explanation:
The Kalika Purana is an important Sanskrit religious text associated with the religious landscape of Kamarupa, particularly the traditions surrounding Kamakhya. It is a later source and should not be treated as a straightforward contemporary political chronicle of the earliest history of Assam. Its importance lies especially in understanding religious and cultural traditions.
21. Which of the following is an example of an external source for the history of Kamarupa?
A. Umachal Rock Inscription
B. Nidhanpur Copper Plates
C. Allahabad Pillar Inscription
D. Nagajari archaeological remains
Correct Answer: C. Allahabad Pillar Inscription
Explanation:
The Allahabad Pillar inscription was not produced in Assam. It nevertheless mentions Kamarupa and Davaka and therefore serves as an important external source. By contrast, the Umachal inscription and Nidhanpur plates are directly associated with the historical geography of Assam.
22. Which source category can provide information about ancient settlement patterns without relying primarily on written records?
A. Archaeology
B. Modern legislation
C. Newspapers
D. Modern census reports
Correct Answer: A. Archaeology
Explanation:
Archaeology investigates material remains such as buildings, pottery, tools, sculptures, hearths, graves and environmental remains. Such evidence can reveal settlement patterns and economic and cultural practices even where written records are absent or limited.
23. Why should literary sources of ancient Assam be used together with archaeological and epigraphic evidence?
A. Literary sources are always false
B. Archaeological evidence is always superior
C. Different sources can corroborate, qualify or challenge one another
D. Literary sources contain no historical information
Correct Answer: C. Different sources can corroborate, qualify or challenge one another
Explanation:
Historical reconstruction is strongest when evidence from different categories is compared. Literary texts may preserve valuable geographical or cultural information, but they can also contain mythology and religious traditions. Archaeology and inscriptions can provide independent evidence that helps historians assess literary claims.
24. Which of the following is NOT normally classified as an archaeological artefact?
A. Pottery
B. Stone tool
C. Metal object
D. Modern newspaper
Correct Answer: D. Modern newspaper
Explanation:
Pottery, stone tools and ancient metal objects are archaeological artefacts because they are material remains of past human activity. A modern newspaper is primarily a documentary source for modern history and is not normally considered an archaeological artefact.
25. Which combination correctly matches the source with the type of information it can provide?
A. Coins — political and economic evidence
B. Pottery — royal genealogy only
C. Copper plates — rainfall measurements only
D. Literary texts — metallurgy only
Correct Answer: A. Coins — political and economic evidence
Explanation:
Coins can provide evidence about rulers, political authority, economic activity, trade, symbols and chronology. Pottery can help reconstruct settlement and cultural patterns rather than royal genealogy alone. Copper plates can provide political, administrative, social and land-grant information. Literary sources can address many aspects of society, religion, geography and politics.
26. Which statement about the study of ancient Assam is most historically appropriate?
A. One source is sufficient to reconstruct the entire history
B. Only literary sources should be used
C. Multiple categories of evidence should be critically compared
D. Archaeological evidence has no value without coins
Correct Answer: C. Multiple categories of evidence should be critically compared
Explanation:
Ancient Assam does not possess an uninterrupted narrative history covering every period. Consequently, historians combine archaeological, literary, numismatic and epigraphic evidence. Cross-checking different sources helps identify agreements, contradictions, chronological problems and gaps in the historical record.
27. Which of the following is an important function of palaeography in the study of inscriptions?
A. Studying ancient climate only
B. Studying the development of scripts and letter forms
C. Measuring archaeological pottery
D. Identifying mineral deposits
Correct Answer: B. Studying the development of scripts and letter forms
Explanation:
Palaeography is the study of ancient writing systems and the development of letter forms. By examining the shape and development of letters, scholars can help date inscriptions and identify their script traditions. Palaeographic analysis is therefore an important component of epigraphic research.
28. What type of evidence can provide information about the boundaries of land donated by an ancient ruler?
A. Copper-plate grant
B. Modern school register
C. Newspaper advertisement
D. Modern electoral roll
Correct Answer: A. Copper-plate grant
Explanation:
Ancient copper-plate grants often describe donated land, villages and their boundaries. These descriptions can include geographical features, neighbouring settlements and administrative units. Consequently, copper plates are valuable for studying historical geography and patterns of landholding.
29. Which statement best describes the historical value of coins?
A. Coins are useful only for identifying metals
B. Coins can provide evidence about economy, authority, trade and chronology
C. Coins cannot provide historical information
D. Coins are literary sources
Correct Answer: B. Coins can provide evidence about economy, authority, trade and chronology
Explanation:
Coins can contain legends, symbols, portraits, religious imagery and indications of issuing authority. Their weight, metal and distribution can also contribute to the study of monetary systems, trade and economic networks. However, their interpretation requires attention to archaeological context and secure attribution.
30. Which approach is most appropriate for reconstructing the early history of Assam?
A. Depending exclusively on mythology
B. Depending exclusively on modern traditions
C. Combining archaeological, literary, numismatic and epigraphic evidence
D. Ignoring external sources
Correct Answer: C. Combining archaeological, literary, numismatic and epigraphic evidence
Explanation:
The history of ancient Assam is best reconstructed through a multi-source approach. Archaeology provides material evidence; literary texts preserve geographical, religious and cultural references; coins provide numismatic evidence; and inscriptions provide direct textual information about rulers, grants and administration. External sources such as the Allahabad inscription and Xuanzang’s account further strengthen the reconstruction when critically compared with local evidence.
