The correct answer is A. Organizing Roman history into 3 main eras
Explanation:
Periodization in history refers to the process of studying and categorizing events of the past in to block of time. This process is aimed at facilitating the analysis of historical events and understanding the causes of specific historical processes. Additionally, periodization is useful as blocks of time are organized according to relatively common characteristics. Considering periodization is applied when categorizing or organizing events of the past, it can be applied to Roman history which result could be 3 main eras with common historical features. Thus, periodization is useful in the case of organizing Roman History.
The Romans brought the benefits of Roman civilization and culture to conquered territories,and thus assimilated their populations (at least,those that hadn't been killed or enslaved during the conquest) into the empire as a whole.
The purpose of this was to win conquered peoples over to the Roman way of life - a higher and more advanced standard of living would reconcile them to Roman rule.
Sometimes though there would be serious revolts against Roman rule - one in Britain and 2 in Judea were the most serious,so this policy didn't necessarily work everywhere all of the time.
