Introduction
Prehistory is the study of the human past before the existence of written records. It covers the earliest stages of human existence, when people left no written documents through which their lives could be directly recorded. Consequently, prehistoric societies are reconstructed mainly through material remains, including stone tools, animal and human bones, fossils, pottery, habitation remains, burials, ornaments, hearths, and rock art.
Prehistory is therefore closely connected with archaeology, anthropology, palaeoanthropology, geology, palaeobotany and palaeozoology. Archaeological evidence is particularly important because the absence of writing does not mean the absence of evidence. Human beings modified their environment, made tools, occupied particular places, used fire, buried their dead, hunted animals, collected plants and eventually developed agriculture. These activities left physical traces that can be scientifically investigated.
For the Indian subcontinent, the study of prehistory is especially dependent on archaeology. Government educational material explains that archaeology helps reconstruct the material life of the past by studying remains obtained from archaeological sites, while the Archaeological Survey of India (ASI) is the country's principal organisation for archaeological research and the protection of archaeological heritage.

1. Meaning and Definition of Prehistory
The word Prehistory literally means the period before history, but the distinction is more accurately understood as the period for which written historical records are absent or unavailable.
In prehistoric societies, writing either did not yet exist or has not left usable written records. Therefore, historians cannot reconstruct their history through chronicles, inscriptions or written documents in the normal way. Instead, they depend mainly on archaeological and scientific evidence.
IGNOU's material on prehistoric archaeology explains prehistory as the stage before history in which there was no documented knowledge in the form of writing. It also notes that prehistoric archaeology studies human origins and development through material remains such as stone, wood, bone, metals, pottery, tools, ornaments and other objects.
A broader definition
Prehistory may therefore be defined as:
> The study of human societies and human development during the period for which written records are absent, reconstructed primarily through archaeological, biological, geological and environmental evidence.
This definition is important because prehistory is not simply a period of “primitive life.” It is a field of historical reconstruction based on material and scientific evidence.
---
2. Prehistory as a Period of Human Development
Prehistory covers an extremely long span of human existence. It begins with the earliest evidence of human ancestors and extends, in different regions, until the emergence or availability of written records.
The chronology is not identical everywhere. A society may enter a literate historical phase while another society in a different geographical region remains prehistoric. Therefore, there is no single universal date at which prehistory ended.
The traditional archaeological classification of prehistoric technological development includes:
Stone Age → Copper/Bronze Age → Iron Age
The Stone Age is further divided into:
Palaeolithic → Mesolithic → Neolithic
The Palaeolithic itself is commonly divided into:
Lower Palaeolithic → Middle Palaeolithic → Upper Palaeolithic
These divisions were originally based substantially on changes in tool technology, although modern archaeology uses much broader evidence, including subsistence, settlement, environment, chronology and social organisation.
---
3. Prehistory, Protohistory and History
Understanding the distinction between Prehistory, Protohistory and History is one of the most important conceptual areas for competitive examinations.
A. Prehistory
Prehistory refers to the period for which written records are absent and knowledge of human societies is reconstructed mainly through archaeological and scientific evidence.
Main characteristics
Absence of usable written records
Dependence on archaeology
Stone tools are particularly important in the earliest phases
Fossils and skeletal remains provide evidence about human evolution
Animal bones provide information about diet and hunting
Plant remains help reconstruct ancient environments and food practices
Burials provide evidence about mortuary practices
Rock art provides evidence about artistic and cultural activities
Geological and environmental evidence helps establish chronology and ecological conditions
---
B. Protohistory
Protohistory occupies an intermediate or transitional position between prehistory and history.
The term is used in different ways by scholars, so it should not be treated as having one universally accepted definition.
It can broadly refer to societies that:
1. had writing but whose script remains undeciphered;
2. had no indigenous written records but are mentioned in the records of literate neighbouring societies; or
3. occupy a transitional position between prehistoric and fully historical societies.
Indian example: Harappan Civilization
The Harappan Civilization is commonly described in Indian educational literature as protohistoric because the Harappans possessed a writing system, but their script has not yet been satisfactorily deciphered.
NIOS specifically notes that although writing was known in the Indus civilisation, the script remains undeciphered; consequently, the Harappan culture is placed in the protohistoric phase in that framework.
This is an important examination point:
Harappans knew writing → Harappan script remains undeciphered → commonly classified as protohistoric.
---
C. History
History generally refers to the period for which written records are available and can be used to reconstruct past societies.
Written sources may include:
inscriptions
manuscripts
chronicles
administrative records
religious texts
literary works
official documents
travellers' accounts
copper plates
letters and correspondence
However, archaeology remains important even after the emergence of writing because written records may be incomplete, biased, limited to particular groups, or concerned mainly with political and religious matters.
---
Prehistory, Protohistory and History: Comparison
Basis Prehistory Protohistory History
Written records Generally absent May exist but unavailable, undeciphered or limited Available and usable
Main evidence Archaeological/scientific Archaeological + limited/undeciphered texts + external references Written + archaeological evidence
Major Indian example Stone Age cultures Harappan Civilization Mauryan period and later literate periods
Major discipline Archaeology Archaeology + history History + archaeology
Main difficulty Reconstructing society without texts Interpreting incomplete/undeciphered evidence Evaluating and interpreting surviving records
Important: These categories are analytical tools, not rigid universal boundaries. Different scholars may classify particular cultures differently.
---
4. Why the Study of Prehistory is Important
Prehistory provides the foundation for understanding the long-term development of human societies.
It helps us understand:
Human evolution
Fossils and skeletal remains provide evidence for physical changes among human ancestors and the development of the genus Homo.
Technological development
Stone tools show how humans progressively developed techniques for cutting, chopping, scraping, hunting and processing resources.
Adaptation to environment
Prehistoric people lived in forests, grasslands, river valleys, caves, rock shelters and other ecological settings. Their remains reveal how humans adapted to changing environments.
Subsistence
Animal bones, plant remains and tools help identify changing patterns of:
hunting
gathering
fishing
food processing
animal domestication
agriculture
Settlement
Archaeological sites reveal changes from mobile camps to more permanent settlements.
Social and cultural development
Burials, ornaments, rock art, ritual structures and other evidence help scholars investigate social relationships, beliefs and cultural practices.
Thus, prehistory helps explain the gradual transformation of human life from early hunter-gatherer communities to increasingly settled and technologically complex societies.
---
5. Sources for Studying Prehistoric Societies
Since written sources are generally absent, prehistoric archaeology relies heavily on material and environmental evidence.
The principal sources include:
1. Human fossils and skeletal remains
2. Animal remains
3. Stone tools
4. Bone and antler tools
5. Wooden remains
6. Pottery
7. Hearths and evidence of fire
8. Habitation remains
9. Burials and graves
10. Rock paintings
11. Rock engravings
12. Ornaments and beads
13. Plant remains
14. Pollen
15. Seeds and grains
16. Charcoal
17. Soil deposits
18. Geological formations
19. Environmental evidence
20. Spatial distribution of archaeological sites
NIOS identifies archaeological sources such as tools, pottery, toys, pictures, inscriptions, monuments and other material remains, while for prehistoric periods tools, habitation evidence, bones, pottery and rock art become especially important.
---
6. Archaeology and Prehistory
Meaning of Archaeology
Archaeology is the systematic study of past human societies through their material remains.
Archaeological investigation generally involves:
Survey → Identification of site → Excavation → Recording → Recovery → Classification → Dating → Analysis → Interpretation
Archaeology is therefore much more than simply digging up old objects.
It attempts to reconstruct:
how people lived;
what they ate;
what tools they used;
where they lived;
how they interacted with their environment;
how their technology changed;
how they buried their dead;
and how their societies developed.
NIOS describes archaeology as the systematic study of successive layers of old mounds and the reconstruction of material life from the remains found in those layers.
---
7. Archaeological Site
An archaeological site is a location where material evidence of past human activity is found.
Sites may include:
caves
rock shelters
open-air camps
river terraces
ancient settlements
burial grounds
workshops
habitation areas
shell middens
megalithic monuments
The location of a site itself is important. Its relationship with rivers, hills, forests, raw-material sources, animals and agricultural land can help explain why people selected that particular location.
---
8. Excavation and Stratigraphy
Excavation
Excavation is the systematic removal and recording of archaeological deposits.
The aim is not simply to collect artefacts but to preserve information about their context.
Why context matters
A stone tool found alone provides limited information.
But if the same tool is found:
in a particular layer,
beside a hearth,
together with animal bones,
near habitation remains,
and within a specific environmental context,
archaeologists can make much stronger interpretations.
---
Stratigraphy
Stratigraphy refers to the study of archaeological layers or strata.
In general, deeper undisturbed layers are older than layers deposited above them.
This principle helps archaeologists establish the relative chronology of archaeological remains.
However, archaeological deposits can sometimes be disturbed by:
animals,
roots,
later human activity,
erosion,
floods,
construction,
burials.
Therefore, stratigraphy must be carefully examined rather than mechanically assuming that every deeper object is automatically older.
---
9. Dating Methods
Scientific dating is essential for prehistoric archaeology.
Relative Dating
Relative dating establishes whether an object or layer is older or younger than another.
Important methods include:
stratigraphy
typology
geological correlation
association with datable materials
Absolute/Chronometric Dating
Modern archaeology also uses scientific dating methods.
Important examples include:
Radiocarbon Dating
Also known as Carbon-14 dating.
It is especially useful for organic materials such as:
charcoal
wood
seeds
bone under suitable conditions
other carbon-bearing materials
Other methods
Depending on the material and archaeological context, scientists may use:
potassium-argon/argon-argon dating
uranium-series dating
thermoluminescence
optically stimulated luminescence (OSL)
electron spin resonance
dendrochronology in suitable contexts
No single dating method is appropriate for every archaeological material. Scientists select methods according to the material, expected age and archaeological context.
---
10. Stone Tools
Stone tools are among the most important sources for understanding the earliest prehistoric societies.
They survive much better than organic materials such as wood, leather and plant fibres.
What stone tools tell us
They provide information about:
technological ability
raw-material selection
manufacturing techniques
functional activities
mobility
hunting and food processing
adaptation to different environments
Important categories
Early prehistoric stone-tool traditions include:
core tools
flake tools
handaxes
cleavers
scrapers
points
blades
burins
microliths
polished stone tools
The sequence of tool technologies provides one of the foundations for dividing the Stone Age into different cultural phases.
---
11. Raw Materials Used for Tools
Prehistoric people selected stones according to their physical properties and local availability.
Materials could include:
quartzite
chert
flint
chalcedony
jasper
basalt
sandstone and other suitable rocks
The choice of raw material can itself reveal information about:
geological environment;
mobility;
exchange or movement of materials;
technological knowledge.
---
12. Fossils
Fossils are preserved remains, impressions or traces of ancient organisms.
In prehistoric studies, fossils are important because they can provide evidence about:
human evolution
biological characteristics
extinct animals
ancient environments
chronology
adaptation
Human skeletal remains can provide information about:
age
sex, where biologically estimable
stature
health
disease
trauma
diet
physical activity
However, interpretations must account for preservation conditions and the limitations of skeletal evidence.
---
13. Animal Bones
Animal remains are extremely important archaeological evidence.
They can help identify:
animals hunted by humans;
animals domesticated by humans;
food habits;
butchery practices;
environmental conditions;
changes in subsistence.
Cut marks, burning, breakage patterns and the location of bones can sometimes provide evidence of human processing.
Animal remains therefore connect archaeology with zooarchaeology, the study of animal remains from archaeological contexts.
---
14. Plant Remains
Plants are often less visible than stone tools because they decay, but archaeological science can recover important botanical evidence.
These include:
seeds
grains
fruits
charcoal
wood
pollen
phytoliths
Such evidence can help reconstruct:
ancient vegetation
diet
agriculture
gathering practices
fuel use
environmental change
The study of ancient plant remains is associated with archaeobotany/palaeobotany.
---
15. Pottery
Pottery becomes especially important in later prehistoric and protohistoric contexts.
Pottery can reveal:
cooking practices
food storage
water storage
craft technology
settlement patterns
cultural traditions
trade and interaction
chronology
Archaeologists study:
clay composition
manufacturing technique
firing
vessel shape
surface treatment
decoration
colour
distribution
Pottery styles can sometimes help identify cultural relationships and chronological phases.
---
16. Hearths and Evidence of Fire
Evidence of controlled fire is extremely significant in prehistoric archaeology.
Archaeological traces of fire may include:
ash
charcoal
burnt stones
fire-cracked rocks
burnt bone
hearth structures
Fire had many possible uses:
cooking
warmth
protection
lighting
processing materials
landscape management
Careful archaeological analysis is required to distinguish deliberately constructed hearths from natural fires.
---
17. Habitation Remains
Prehistoric settlements can be identified through:
floors
post-holes
walls
pits
hearths
tool concentrations
food remains
storage features
refuse deposits
These remains help reconstruct the organisation of prehistoric communities.
They can indicate whether people were:
highly mobile;
seasonally mobile;
semi-sedentary;
or permanently settled.
---
18. Burials and Graves
Burials are among the most valuable sources for understanding prehistoric social and cultural life.
Archaeologists examine:
position of the body;
orientation;
burial method;
grave construction;
associated objects;
animal remains;
ornaments;
pottery;
weapons or tools;
evidence of repeated burial practices.
What burials can reveal
Burial practices can provide clues about:
attitudes toward death;
ritual behaviour;
social identity;
possible status differences;
community organisation;
health and disease;
diet;
mobility.
However, archaeologists must be careful not to automatically interpret grave goods as proof of social rank. Different explanations may be possible.
---
19. Rock Art
Rock art includes paintings, engravings and other images made on rock surfaces.
It is an important source for prehistoric cultural history.
Rock art may depict:
animals
human beings
hunting scenes
dancing
group activities
weapons
geometric symbols
ritual or symbolic scenes
Importance
Rock art can provide evidence about:
artistic expression;
human-animal relationships;
hunting;
social activities;
symbolism;
cultural traditions.
One of India's most important examples is the Bhimbetka Rock Shelters in Madhya Pradesh.
Government cultural documentation records prehistoric occupation at Bhimbetka and notes extensive rock art spanning long periods, including Mesolithic and later phases. The site is protected by the Archaeological Survey of India and was inscribed as a UNESCO World Heritage Site in 2003.
---
20. Colours Used in Prehistoric Rock Paintings
Prehistoric painters used naturally available mineral and organic materials.
At Bhimbetka, documented pigments include:
red, associated with iron oxides;
black, including charcoal and manganese dioxide;
white, including lime-based material.
The survival of these pigments over long periods makes rock art an ibmportant archaeological source.
---
21. Ornaments and Personal Objects
Prehistoric ornaments may include:
beads
shells
bone ornaments
stone ornaments
teeth
pendants
These objects can provide information about:
personal identity
aesthetic preferences
symbolic behaviour
social relationships
long-distance movement or exchange
If a material originated far from the archaeological site, it may indicate movement, exchange or interaction between communities.
22. Environmental and Geological Evidence
Prehistoric humans lived within changing environmental conditions.
Therefore, archaeology also studies:
soil
sediments
river terraces
pollen
animal species
plant remains
climatic indicators
geological formations
Such evidence helps reconstruct the environment in which prehistoric people lived.
This is important because changes in climate and environment could influence:
availability of water;
animal populations;
vegetation;
mobility;
settlement;
subsistence strategies.
23. Archaeological Evidence and Its Importance
Archaeological evidence is particularly important for prehistory because written records are unavailable.
It allows researchers to reconstruct different dimensions of prehistoric life.
Technology
Tools reveal technological knowledge and manufacturing skills.
Economy
Animal and plant remains reveal subsistence and food practices.
Settlement
Habitations show patterns of mobility and settlement.
Environment
Geological, botanical and zoological evidence reconstruct ancient environments.
Social organisation
Burials, settlement structures and distribution of objects provide clues about social relationships.
Religion and symbolic behaviour
Burials, rock art and unusual objects may provide evidence for ritual or symbolic activities.
Cultural change
Changes in tools, pottery, settlements and subsistence through successive archaeological layers help reconstruct cultural transformation.
24. Limitations of Archaeological Evidence
Archaeology is extremely important, but archaeological evidence has limitations.
Preservation bias
Stone survives better than wood, leather, fibres and many organic materials.
Therefore, the archaeological record does not represent everything that once existed.
Incomplete evidence
Only a fraction of past human activities survive archaeologically.
Disturbed contexts
Floods, erosion, animals, roots and later human activity can disturb archaeological layers.
Interpretation
The same archaeological object may have more than one possible interpretation.
For example, an unusual stone object may be:
a tool,
a ritual object,
a production waste piece,
or a naturally modified stone.
Therefore, archaeologists use context, comparison and multiple lines of evidence rather than relying on one object alone.
25. Archaeology is Interdisciplinary
Modern prehistoric research is not limited to archaeology.
It combines archaeology with:
Anthropology
Studies human biological and cultural development.
Palaeoanthropology
Studies human evolution through fossil and skeletal evidence.
Geology
Helps understand sediments, landscapes and geological chronology.
Palaeobotany / Archaeobotany
Studies ancient plant remains.
Archaeozoology
Studies animal remains from archaeological sites.
Physical anthropology
Examines human skeletal remains.
Chemistry and physics
Assist with dating, material analysis and residue studies.
Genetics
Ancient DNA, where preservation permits, can provide information about population history and biological relationships.
Environmental science
Helps reconstruct past climates and ecological conditions.
This interdisciplinary approach has greatly expanded the ability to reconstruct prehistoric societies.
26. Major Indian Examples Relevant to Prehistory
Bhimbetka – Madhya Pradesh
Famous for its prehistoric rock shelters and paintings.
Government documentation describes the site as preserving some of the earliest traces of human occupation in the Indian subcontinent and records rock art extending across long chronological periods.
Attirampakkam – Tamil Nadu
An important prehistoric archaeological site associated with early Stone Age occupations.
Hunsgi Valley – Karnataka
Important for understanding prehistoric stone-tool cultures and human occupation.
Burzahom – Kashmir
An important Neolithic archaeological site, particularly known for distinctive settlement and burial evidence.
Chirand – Bihar
Important for Neolithic cultural developments in the Ganga region.
Daojali Hading – Assam
An important Neolithic site of Northeast India and particularly relevant for Assam and Northeast India-based examinations.
NIOS notes that prehistoric artefacts have been found in Assam and neighbouring areas including Meghalaya, while prehistoric cultures were widely distributed across the Indian subcontinent.
27. Prehistoric Evidence in Assam and Northeast India
For ADRE and APSC, the Northeast should not be neglected.
Prehistoric evidence from Assam and neighbouring areas demonstrates that the region participated in the wider development of prehistoric cultures.
Important areas to study include:
prehistoric stone tools;
Neolithic tools;
polished stone axes;
pottery;
settlement evidence;
geographical distribution of prehistoric sites;
relationship between Northeast India and wider South/Southeast Asian prehistoric traditions.
Government NIOS material specifically records prehistoric artefacts from Assam and neighbouring Meghalaya, making the region important in the study of Indian prehistory.
