Answer:
Political science.
Step-by-step explanation:
The study of history is closely related to the study of political science. This is so because history, which is nothing other than the study of past events and their consequences, is primarily made up of political decisions that have a direct impact on the development of events in a particular social group or nation.
Thus, the decisions of a certain politician can give rise to wars, whose development and consequences are subsequently analyzed by history. In this way, the analysis in the light of political science of past events allows us to better understand history and relate it directly to events in the present.
