Answer:
So it doesn't take a rocket scientist (or in our case, a professional historian) to realize that historical events are caused by other historical events that take place first. For example, high taxes and bread shortages led to the French Revolution in 1789, which eventually led to the execution of King Louis XVI, which in turn led to ten years of chaos under the First French Republic, which created the conditions under which Napoleon Bonaparte could come to power. We call this process historical causation. Historical causation is the process of cause and effect evident throughout the flow of history. Historical causation is super important to historians and those studying history because it answers questions like: 'How did this happen?' or 'Why did this happen?'
