Periodization.

Periodization is the practice of dividing the past into separate blocks of time in order to facilitate the study of history. This categories are created based on some stable characteristics. However, the beginning and end of any period is often difficult to establish, as history is one continuous process, without any clear cut breaks.

The terms "Middle Ages," "Enlightenment," and "Renaissance" refer to this type of categories.

the process is called revolution because it was a process of great economic-social transformations that began in england in the xviii century.

the industrial mode of production spread throughout much of the northern hemisphere throughout the xix and early xx centuries.

the effect of this revolution was the distance between the countries, with respect to economic and political power.   after all, not all industrialized at the same time, remaining in the condition of suppliers of raw materials and agricultural products to the industrialized countries.

these differences mark to this day the nations of the world that are divided between developed and developing countries. one way to measure whether a country is advanced is to assess how industrialized it is.
