Dates play a significant role in history. History is associated with dates as specific dates can be determined for the events in the past. History in the past was an account of battles and big events. It was about the rulers and their policies.
There can be specific dates for events such as when a king was crowned, when he married, when he had a child, when he fought a particular war, when he died, and when the next ruler succeeded to the throne. Thus, dates become important in history.
