I'm sorry, RobinHat, for a very late answer but I've been having more trouble than usual with my internet connection lately (and I still can't auto-quote messages). Anyway I'll try to answer your questions and in a way to lead us back on topic, wich should be what kind of scandinavian civ(s) should be in the game.

What historians? What general opinion? I don't believe that there is a general opinion stating that Skåne was ever invaded/conquered/annexed by Denmark. Why, if it is such a generally accepted fact, are you unable to answer any of my questions that at the very least would clarify and back up your claims?
Again, I stated that Skåne was more permanently tied to the Danish realm sometime during Harald Bluetooths rule in the 970s wich is what I've read, whenever I 've read about that period. If you want names of books I can give you a few that is in my posession (see below) but I must repeat myself; I've never heard/read any theory to the contrary. If you have another theory please present the evidence.
List of books in IF:s library especially mentioning Harald Bluetooths unifying of Denmark:
Sveriges Historia (Swedens History) - Norstedts Förlag (mentioned part written by Dick Harrison, a history professor at Lunds University
Svensk Historia (Swedish History) - Alf Henriksson, partially mentions the event
Nordisk Vikingaguide - Statens Historiska Museum
Politikens Etbinds Danmarks Historie- Grethe Jensen & Benito Scocozza
Arkeologi I Norden - Göran Burenhult
Archeological findings, inscriptions on runestones, medieval texts and icelandic sagas as well as for example the scientific dating of the trelleborg-forts, built on strategical locations all over Denmark, to this particular period, are what these historians base their theories on.
[Canute] did call it LVND DENEMAC, which means 'London of Denmark', because London in England was spelt 'LVND' by Danes in Canute's time.
Go back and read
Öjevind Långs post (#173). I think he did a good job in showing the difference of Lund and London and that
"The name emphatically is not a Scandinavian version of the English London".
That Lund means grove, and that it got it's name for being a sacred grove and not for resembling an english place
is without a doubt.
Moving in on topic...
RobinHat, I actually believe we are not too far apart on opinion despite our continous Skåne-debate. What I object too is your statement that "Skåne is Danish", because it suggests that there is a Danish nationality differing from that of the Swedes. The people of Skåne are Scandinavians and whether they would come to belong to the Scandinavian states of Denmark or Sweden is a matter based on other aspects than national identity. The Danes were one of many Scandinavian tribes who began forming their realm in southern S during the first half of the first millenia (perhaps in the 400s or 500s). They expanded from there but in ways typical of that time the realm was loosely held together based on the might of individual leaders and falling apart from time to time until the end of the first milennia and the rule of Harald Bluetooth and perhaps with the help of a new religion.
I believe that there are two things, that more than any other, have played a part in making Skåne a part of Sweden; The ever increasing ease of traveling by land instead of by sea, and the fact that foreign powers don't want one country to control the Öresund strait, and this factor, has also played a significant role in keeping Scandinavia divided. For
Civ5 however, I wish to see a united Scandinavia again, and the only problem I can find with that Civ is whether the citylist should have a viking age emphasis or a more modern look.
) I agree that the swedish vikings wasnt really plunderers like the danish but they did go for long trade missions. However sweden was quite large in the 1600-1700 and defeated a alliance consisting of russia, denmark and polen, however they didnt conquer russia but they tried and got the same treatment as napoleon and hitler. And the dansih was quite powerful during this era also, not as powerful but they held a pretty central position in europe.
