The core idea
A source is evidence for particular questions, not a complete window onto the past. Historians establish its origin and context, compare it with other evidence and explain both what it supports and what remains uncertain. Dates organise an explanation; they do not replace one.
Chronology is the frame, not the whole picture
Chronology places events in sequence. BCE counts years before the Common Era; within BCE, a larger year number is earlier. A century covers one hundred years, while c. or circa signals an approximate date. Historical periods are analytical groupings, not walls that made every region change together overnight. The urban or Mature Harappan phase is commonly dated about 2600–1900 BCE, but the beginnings and later changes of particular settlements need their own evidence. Ask what changed, for whom, over what area and at what speed. A new road might change traders’ journeys quickly while household routines change slowly. Continuity and change can coexist. Also distinguish an event’s date from a source’s date: a memoir written decades later describes an earlier experience through later memory. Both dates matter to interpreting what it can tell us.

A source answers a specific question
A primary source comes from the period or experience being studied; a secondary account interprets sources. These labels depend partly on the question. A modern history textbook is secondary evidence about an ancient settlement, but it can be a primary source for a future study of how our generation taught history. Primary does not automatically mean accurate or impartial. A ruler’s inscription, a merchant’s account and a household tool preserve different kinds of information. Establish provenance: who created or used the object, when, where, for what audience and how it reached the collection. Then separate the source’s statement from your inference. A tax record may document an assessed amount without proving that every payment was collected. A missing name can reflect the record’s purpose rather than the nonexistence of a person or group.

Worked case: what Harappan drains establish
NCERT describes drains linked to houses and streets at Mohenjodaro, and standardised proportions in many Harappan bricks. These remains support an interpretation of coordinated construction and attention to drainage. They do not, by themselves, identify a particular king, show that every resident had equal power or reveal exactly who cleaned the drains. The distinction matters: an impressive technical achievement can be recognised without inventing a complete political system. The Harappan script remains undeciphered, so claims that a seal gives the full name of a ruler require evidence beyond an attractive reading. Archaeologists combine layout, objects, material remains and comparisons, while preserving uncertainty about purposes that cannot be directly observed. For example, the Great Bath’s structure is visible, but its precise social and ritual use is an interpretation. Strong history states where the evidence ends and the hypothesis begins.
Trace → supported inference → open question
| Evidence | What it supports | What it does not settle |
|---|---|---|
| House and street drains | Coordinated construction and drainage | Who ruled or cleaned them |
| A ruler’s public instruction | An intention communicated | How widely people complied |
| A later remembered account | A person’s recalled experience | Every detail of the earlier event |

Worked case: Ashoka’s words and their reach
Ashoka’s inscriptions are important evidence for Mauryan rule and the ideals he publicly promoted. NCERT describes messages about respect toward elders, kindness to servants and regard for other traditions. From such an inscription, a careful conclusion is that the ruler wanted these principles communicated. A stronger claim that everyone practised them would require different evidence. Language, location, readers, oral explanation and local power all affect how a message reaches people. Most Ashokan inscriptions used Prakrit, while examples in the northwest also used Greek and Aramaic; language and script must not be confused. The same ruler’s messages appearing in different regions reveal communication, but do not prove identical administration everywhere. Historians compare wording, places and other remains. Reading a royal claim critically neither requires dismissing it as worthless nor accepting its self-description as a complete account of society.

Explain change through connected causes
A historical explanation does more than list events in order. A fictional town’s market may grow after a bridge opens, but the bridge might work together with demand, transport services, security and traders’ decisions. Distinguish a background condition from a trigger and from the mechanism connecting them. A bridge can reduce travel difficulty; that reduction may make certain journeys worthwhile. To test the explanation, ask whether trade changed on routes that did not benefit from the bridge, and whether growth had already begun. People act within conditions they did not fully choose, but they also make decisions with consequences. Avoid explaining an entire period through one heroic person, one technology or a supposedly fixed national character. Multiple causes do not mean that every cause mattered equally. A strong account explains their relative importance and the limits of the available evidence.

Read absences and disagreements carefully
Not every past life leaves the same kind of record. Durable stone can survive where cloth decays; literate and powerful people may appear in written archives more often than others. Therefore absence of a surviving source is not automatically evidence that something never happened. Yet an absence can matter when the proposed claim predicts abundant evidence in places thoroughly investigated. Explain that expectation instead of using silence selectively. Oral histories can preserve experiences excluded from official documents, while memory still needs attention to timing, perspective and later influence. Corroboration means bringing different evidence into conversation, not counting repeated copies as separate witnesses. When sources disagree, ask whether they describe different places, dates or social positions. A responsible narrative can contain firm conclusions alongside open questions; acknowledging uncertainty strengthens it when the uncertainty is real and specific.

PUT IT INTO PRACTICE
Practise: write a small history from invented records
- Use three invented records about a reading room: a dated 1995 opening invitation, a 1996 register with thirty names, and a 2020 interview recalling that “everyone used it”. Label them fictional evidence for practice.
- For each record, state one supported claim and one unsupported leap. Distinguish an invitation from proof that the event occurred, and registration from daily attendance.
- Write an eighty-word account with dates, qualifications and one further question. Consider whose use might be absent from the register.
- Solution reasoning: the invitation supports a planned opening, the register records thirty names, and the interview conveys a later memory of wide use. Together they suggest activity but do not prove universal attendance. Seek event reports or further independent accounts before strengthening the claim.
Check your understanding
Which came earlier, 500 BCE or 300 BCE?
500 BCE came earlier. The numbers decrease as the timeline approaches the Common Era; confusing that direction reverses a historical sequence.
Is a primary source necessarily more truthful?
No. Its proximity is useful, but purpose, perspective and conditions still matter. A contemporary boast can mislead while a careful later comparison clarifies it.
What do drains not establish by themselves?
They do not identify a ruler or show equal social power. Those claims need additional evidence beyond the drainage system’s visible construction.
Why distinguish a royal order from practice?
An order establishes an expressed intention or instruction. Actual implementation depends on communication, local circumstances and compliance that the order alone cannot demonstrate.
Why is chronology insufficient for explaining a market’s growth?
An earlier event may be unrelated to a later one. Explanation needs a plausible mechanism and comparison with alternatives, not merely the word “after”.
When can absence of evidence matter?
When a claim gives strong reasons to expect evidence in a well-investigated place or record. State those expectations and the search limits before drawing a conclusion.
