Definition
Memory is the capacity to encode, store, and retrieve information. At the individual level it underlies learning and identity; at the collective level it refers to the shared body of stories, customs, and history that a society preserves and passes down.
In world history, collective memory is the mechanism by which cultures maintain continuity across generations, especially before and alongside the development of writing.
Why it matters
How it works
Cultures developed deliberate techniques to make memory reliable: rhythm, rhyme, repetition, performance, and ritual all reduce the chance that knowledge is lost or distorted. Specialists such as bards, priests, and elders served as living archives. The invention of writing did not replace memory but extended it, allowing knowledge to outlast any single person. Yet writing also reshaped memory by fixing some versions of events while letting others fade, making the historical record selective rather than complete.
