Historical Significance
High School
Definition
A judgment about why particular events, people, or developments in the past are considered important. Significance is not fixed; historians decide it based on how deeply something affected people's lives, how widespread its impact was, and how long its effects lasted.
Worked examples
The invention of the printing press (c. 1440) is historically significant because it transformed how knowledge spread across Europe, affecting millions and shaping the Reformation and Scientific Revolution.
This event had deep impact (changed literacy and learning), wide reach (across continents), and lasting effects (centuries).
A local mayor serving one term in a small town may have little historical significance beyond that community, even if well-liked at the time.
Limited impact, narrow geographic reach, and brief duration mean historians judge this as less significant.
Common mistakes
- An event is significant only if it happened long ago. → Significance depends on depth, breadth, and duration of impact, not just age. Recent events can be highly significant if their effects are profound and widespread.
- Significance is a fact that never changes once decided. → Historians re-evaluate significance as new evidence and perspectives emerge. What one generation sees as important, another may view differently based on changing values and knowledge.
Where you'll use it next
You'll apply historical significance when writing essays that argue why certain turning points, figures, or movements matter, comparing events' relative importance, and evaluating primary sources in advanced history courses and research projects.
