Hmm, well given it's a science-fiction novel, the historical information about the period is that it takes place in the future. The reason the hunger games take place every year is because there is a lack of food, so it's a way of controlling the population (I think) and because they are trying to "keep world peace" but really to control everyone. Hope this helps, the question was kind of confusing so if you could elaborate more, maybe I could help more.
