And today is observed as representative of not one, but two of the above. In the United States, this Monday in October is chosen as Columbus Day. I commented on that this Saturday past. The second is the recognition of the impact of the Battle of Hastings which is said to have been fought on October 14, 1066.
The events leading up to this conflict were precipitated by the death of King Edward in January of 1066, and specifically by his failure to provide a clear heir to the throne. Harold Somebody-or-Other was crowned king, but there were other pretenders to the throne. Among them were Duke William and King Harald III, or Harald Hardrata of Norway. Anyway, in a series of conflicts with King Harold, both Hardrata and Tostig, brother of King Harold who supported Hardrata, were killed in battle by Harold's forces at the Battle of Stamford Bridge in September. This set the stage for William, and the rest as they say, is history. Well, so were the events that preceded. Volumes have been written about the Battle of Hastings in which King Harold lost his life and the kingdom to the Norman. And that is the way things were in England, 947 years ago.
William has been known ever after as William the Conqueror.
King William I, 1066 - 1087
