In my opinion I think we should study people and events about the past because it helps us understand our present society we learn how it was like back then and how hard the times were for people it’s like stepping into someone’s shoes or going back into time it helps us understand the point of view of different people from back then and how there lives were different then ours today also many historical events that happened in the past effected or changed and grow the present day society and it still will in the future because in my opinion we need to understand the past in order to understand the present and our future.
Hope this helps!
