In a typical Gregorian calendar of 365 days, there are hardly a few of them which may seem prominent to us. We might conclude that the others have no significance at all, but a bit of research might prove this assumption of ours incorrect. Various online sources cite different iconic events to have occurred on a particular date of the calendar. A glance through the list of several such events to have occurred on March 21, might leave one completely surprised. These episodes include wars and political developments. Various renowned incidents related to the ‘World War II’ have occurred on this date, which not many are aware of. Apart from conflicts, many significant political developments from around the world, which took place in the 11th and 12th centuries on this date, have also been recorded. These include the crowning ceremonies of several famous emperors and empresses. Those who indulge in studies related to world history can speak in length about the prominence of March 21. So, if you thought March 21st is yet another day of the year, this list might give you second thoughts.
