By the danish OR the vikings? The danes were vikings too.
Danish Knut den Store(Canute), with help from the Norwegian Eirik Jarl, at that time the most skillfull strategist in the northern lands, did conquer England yes, all of what they at that time considered to be England in our tongue.
It is clearly visible in the north germanic languages that we are indeed from Germany, even i can understand parts of Frisian TODAY, just by the knowledge of my own tongue.
Same goes for the culture, there are plenty of things that bind the Germanic cultures together. That each germanian culture has diffrence, that is quite obvious, and we in Scandinavia managed to hold onto our culture longer then the others as we were further away from foreign influence. This is especially true for Iceland, mid,west and north-Norway and inland west-Sweden.
That they have been overused and sometimes adding things that have nothing to do with them(mostly the horns) i agree with. But the architecture and other things are mostly correct. As you would know if you had actually studied this. We use the same building style in Norway still today, both stavlaft and laft. Only out of the 3 building styles the viking use its grindbygg that is not used for houses anymore in Norway. But it is still used for eating-halls and various other things, aswell as recreation, a few recently put up in Romsdal by the viking organization there.
Woodcarving dragonstyle(called drageskurd) is also a old tradition in Norway, more common here then in Sweden and Denmark or Iceland, and still very much in use today, which i would know since im taking a course in it.
The biggest error hollywood and others do, when picturing vikings, is, apart from the horns, that they show us ONLY as warriors. And often too brutal or simply evil.
The movie Pathfinder is probably one of the best examples for that, piece of crap.
We were hardly any more barbaric or brutal then other people in Europe at the time. The diffrence is that the other Europeans, Charlemagne for instance, was christian, and the people who wrote the books were christians, we were not.
The barbaric view is mostly spewed out by christian monks in Britain. But the norse litterature dont do this.
You really don't get it do you?
Firstly Scandinavians are not from Germany because when they migrated to Scandinavia there was no Germany to come from. There was just a group of loosely affiliated tribes that we describe as Germanic due to there close set of genes. Scandinavians are Germanic yes but not German. That describes a completely different cultural type.
Secondly yes the styles that are represented in the moves and games do exist in Scandinavia but they do not necessarily come from there. due to the northern migration from Europe these styles exist all across Europe. Most importantly their cultural origin is from the Angles, Saxons and Germanic tribes. Not from Scandinavia.
Thirdly Knut never conquered all of England, just parts of northern England. The Breton and Saxon areas were far larger and developed their own cultural types independent of one another.
And yes i recognize that the Scandinavian literature paints a different view. Having studied archaeology for 5 years i would hope I'd have noticed that by now. Also horned helmets do exist. They just date to the Bronze age instead of the migration period.
