Sources, Evidence and Chronology — lesson overview
Historical evidence
A primary source is evidence produced in the period or context under study, such as an inscription, coin, official document, or contemporary account. A secondary source interprets evidence after the event.
The usefulness of a source depends on its purpose, authorship, context, survival, and the question being asked. A contemporary source is not automatically unbiased.
Archaeological and written evidence can complement one another. A coin may indicate a ruler’s claim or economic circulation; it does not by itself explain every aspect of society.
Chronology and causation
Chronology arranges events in time. Causation explains why a development occurred. An event occurring earlier does not, on its own, prove that it caused a later event.
BCE years decrease towards 1 BCE; CE years increase from 1 CE. The conventional BCE/CE calendar has no year zero. For example, 200 BCE is earlier than 100 BCE.
Historical explanations often distinguish long-term conditions, immediate triggers, and subsequent consequences. These categories prevent a complex event being reduced to a single date.
Continuity and change
Political rulers may change while farming patterns or social customs continue. Conversely, gradual economic change can transform society without a single dramatic political event.
Comparisons should use the same dimension: administration with administration, trade with trade, and social relations with social relations.
When sources disagree, compare their perspective and evidence rather than deciding solely on which account sounds more confident.
