This is an example of periodization. This is when you classify eras and periods in history according to their chronological order. Of course, it's never that simple since the eras often last longer or shorter than what history says, and they are often connected with others and overlap with other eras.
Periodization is the right answer.
The process of classifying the past into quantified, discrete, named slabs of time, in order to promote the research and analysis of history is known as Periodization. This results in clear concepts that provide acceptable terms for periods of time with relatively durable features. A period of history is a particular time frame including general characteristics. Therefore, breaking history into periods of time is an example of periodization.
