Recently I completed a course here at U of H all about the medieval Normans and their conquests in England, Sicily, and other adventures. (And much of my interest is due to my own last name, which I can trace back to some of the movers and shakers of the period). One thing struck me as odd, hence my bringing up the subject.
It is well known that before the Normans went to England, they had been in Neustria/Normandy for a few generations, where they meshed with the Franks and converted to Christianity (in their own way). One of the first Norman Christians was William the Conqueror's great-great-grandfather, William Longsword. This William was not the only one with this nickname, either. The Conqueror's father, Robert the Magnificent, was also sometimes called Robert Longsword, as was the Conqueror's own son, William Rufus. (So there are at least two different 'William Longsword' and one 'Robert Longsword').
Now, from participating in ARMA and reading stuff on historical fencing, I've been under the impression that the term 'longsword' refers to two-handed swords, such as the German Langenschwert, though of course there is variety in what exact model of 2-hander the term can apply to. In his earlier book 'Medieval Swordsmanship' (and I don't know if this has been edited by continuing research) John Clements stated that while 2-handed swords really became popular in the 1300s and later due to advances in armor, there were around possibly as early as 1150. However, the first William Longsword lived from 928-943.
So I have a few possible explanations:
1. The Norse did in fact make some kind of 2-handed sword, even though all artwork I've ever seen of the Norse or the Norman warriors shows them with one-handers and shields (like in the Bayeaux Tapestry) and I've normally thought of them needing the shield due to the lack of the crossguard. If this is true, the 2-hander must not have been common.
2. The Norse/Normans called their one-handers 'longswords' and the name has nothing to due with larger, later-period swords. If this is the case, plenty of historians need to stop calling the weapons 'viking broadswords' (Well, they need to stop this anyway).
3. Because swords were made by hand, they will have different dimensions to some degree, and William Longsword's weapon was simply LONGER than his subjects, while still being a one-hander.
4. The nickname has absolutely nothing to do with actual swords, but rather some part of William's (and later Robert's) personality or physique. The Norse were known for giving odd nicknames, after all. (I really doubt this last one, though, because I don't think multiple members of the same family would get the same nickname across generations, but I could be wrong).
Yet it could still be something else, so does anyone else have light to shed on the origins of the term 'longsword' with regard to early English, French and Norse peoples?
