A year in history that I find the most interesting is 1066. It is a year that changed English history and influenced the rest of European history. Also, I am a big Harold Godwinson (Harold II) fan and I think he deserves a lot more credit that what he is remembered for in history (i.e. getting killed by an arrow to the eye and losing to William). He was a good king and military leader who got put into impossible situations. Granted, he may have had some over confidence in his decision making and just plain bad luck. The whole world knew it was going to be a bad year after seeing the great comet fly through the sky (tho today we know this as Halley’s comet) providing a bad omen.
In my opinion, with just a few situations changed, the history of 1066 (and the course of English history) could have been very different.
