aspects of History that have impacted Human Society, writing homework help

How has an aspect of History impacted Human Society?I need help on my argumentative essay to come up with ideas. Thank you. I have to write an argumentative essay on how a particular idea or area in my discipline which is history (including any concept, theory, etc., but not a person) has made an impact on society, convincing an educated reader of your position. My thesis must be arguable, that is, it must make a specific claim that is based on evidence and is debatable. (i.e. someone could conceivably disagree with you)
