Why do historians give names to different periods in history?

Historians give names to different periods in history to categorize and simplify complex events, social changes, and cultural developments for easier analysis and understanding. These labels help to delineate significant shifts in human experience, such as the Renaissance or the Industrial Revolution, allowing for clearer communication about the characteristics and impacts of those times. Additionally, naming periods aids in identifying patterns and trends, facilitating a more organized study of historical narratives.
