History & Knowledge (DP IB Theory of Knowledge): Revision Note

History & knowledge

• Historical knowledge is built by selecting and interpreting evidence to justify claims about past events

• This type of knowledge allows knowers to link events through causes, consequences and conditions

• It increases understanding of human perspectives, using sources to infer the motives and values of historical individuals

History as interpretation of the past

• History relies on interpretation; historians must infer what happened, and why, from incomplete traces, and then justify how those traces support their claim

• Historians’ decisions shape the final account, because they must decide which evidence counts and how strongly it supports a claim, e.g.:

  • which sources are relevant to the question being asked

  • how reliable each source is, e.g. bias, purpose, proximity to events

  • how to resolve conflicts between sources e.g. privileging one, combining them or treating disagreement as evidence in itself

  • how to interpret gaps in the record, e.g. absence as “did not happen” vs “not recorded”

• Different interpretations can be judged by how well they fit the evidence, how thoroughly they address counter-evidence, and the extent to which they rely on assumptions

The "past" vs "history"

• The past is what actually happened, while history is the constructed account made from surviving evidence and interpretation

• The past cannot be directly observed now, so historians rely on sources that are incomplete, selective and sometimes biased

  • E.g. if only diaries written by wealthy or powerful people survive, the resulting “history” may overrepresent elite concerns

• Because evidence is partial, historical knowledge often includes uncertainty

  • Historians can justify a claim as the best-supported interpretation without claiming absolute certainty

Historical significance

• Historical significance means judging why an event or person matters enough to be included and emphasised in an account

• Significance depends on explicit criteria that must be justified rather than assumed, e.g.:

  • scale of impact

  • duration of effects

  • symbolic meaning

  • relevance to a guiding question

• Different communities can rank significance differently because their aims and values differ; this changes which knowledge claims get highlighted

  • E.g. a public health lens may elevate disease-control policies, shifting attention away from military events and changing what is treated as a key turning point
