Historical timeframes refer to the divisions of history into distinct periods to help organize and understand events. These periods can range from broad eras, such as the Ancient or Modern periods, to more specific times like the Renaissance or the Industrial Revolution. Each timeframe is characterized by unique social, political, and cultural developments. Historians often use these timeframes to analyze changes over time and the impact of significant events. For example, the Middle Ages saw the rise of feudalism, while the 20th century was marked by two world wars and rapid technological advancements. Understanding these timeframes helps contextualize historical narratives.
