prepare a flowchart showing written sources of history. Explain the importance of any two written sources.

History (from the Greek ἱστορία, meaning 'a learning or knowing by inquiry') can be broadly taken to indicate the past in general but is usually defined as the study of the past from the point at which there were written sources onwards.

There are obstacles that make it so we do not have a crystal clear, uninterrupted view of the past. Firstly, we have to remember that everyone – not just us, but also people throughout history – is shaped by their upbringing and the societies and times they live in, and we need to be careful not to stick our own labels and values onto past periods. Secondly, our view of the past is made up from the total of things that somehow happened to survive the test of time, which is due to coincidences and decisions made by people before our time. So, we only get a fragmentary, distorted view; it is like trying to complete a puzzle with a lot of oddly shaped and missing pieces

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.
