The same themes apply to people living in very different times and places.
Students of history think about timeframes, or periods of time, by considering what are the most impactful events of a period. Every period in history makes a picture of the world or a locale during that specific period of time. By observing historical themes, you can actually see how the same thing might happen to different people and how many mistakes are repeated through the course of time.
The same themes apply to people living in very different times and places. (I think)
Historians study periods of time because it organizes history based on major events or themes of the period. Each period in history creates a snapshot of the world or a region during that time. Cultural diffusion, migrations, and trade help to connect areas which leads to a transfer of ideas and way of life which then creates the period themes.
