Many history classes in both universities and high schools spend time teaching dates and locations of important events.
Yet, History, as a subject, is important, in my opinion, because of the lessons we can learn from the historical events. Yet, the dates and locations of events is really only important in cases where they overlap, and thus interact, with other events.
Am I underestimating the frequency that dates and locations play a critical role in History, or am I missing something else?
I am looking for times where dates and times have played a major role in the study of History (or when the lack of accurate dates and times have been a major detriment to the study of History)
