🧐 Questioning Historical Sources
Before you trust an old source, ask who made it, when, and why — then check it against other sources to see if the facts line up.
What you’ll learn
- Ask Three QuestionsAsk who made a source, when, and why, and explain how the answers change its trustworthiness.Before trusting a source from the past, historians ask three questions: who made it, when they made it, and why. A source made by the winning side, or made long after the event, may tell a bent story. Knowing who created a source and for what purpose changes how much weight it should carry.
- Check It Against OthersCorroborate a fact by checking whether sources agree, and investigate why they might not.Even after questioning a source, historians corroborate it — they check it against other sources. When several independent sources agree, a fact is more trustworthy. When they disagree, that is a clue to dig deeper: someone may have misremembered, wanted to look good, or seen a different part of the event.
- Be the DetectiveCombine questioning and corroboration to judge competing accounts of an event.Being a source detective means doing both steps: first question a source (who, when, why), then check it against other sources. Applied to two reports of one event — like a winning and a losing team describing the same day — this shows why you can't trust a single account alone, and how comparing them reveals a fuller truth.
