If we cannot agree on what was important yesterday, what more on events that happened a hundred or three hundred years ago? The point here is that history is open ended and we cannot be sure about the past. So why study history? Because it teaches us to see the connections between events. Knowing how and why a certain event happened is helpful because in many cases people separated by time and place can sometimes be in similar situations. They can be mentally contemporaneous without knowing it. History gives us hindsight.
