Historians divide a particular duration of time with a distinct start and end date into?

Historians divide a particular duration of time with a distinct start and end date into "periods" or "epochs." These divisions help organize history into manageable segments for study and analysis, allowing historians to focus on specific events, cultural developments, or social changes that characterize each period. Examples include the Renaissance, the Industrial Revolution, and the Middle Ages. Each period is often marked by significant historical events, trends, or transformations.
