Is it true, that Denmark once decided

over England; Northern Germany, Norway and even Europes only superpower today, Sweden?

...for starters it's not 'decided over' - it's 'ruled over'
Those were the days with the vikings ruling everywhere - includind the countries/areas you mention.
But how come you write "...even Europes only superpower today, Sweden" - that country is not even super 😉

- but to decide over several big countries.
Here Sweden is considred as the only superpower of Europe, even if they did not produce the worlds best fighter-crafts from Saab Aircrafts.

Norway
Northern France
England
Northern Germany
Estonia
Latvia
Lithuania
Southern Sweden
Greenland
Faroe Islands
- these are just off the top of my head, may be missing a few.

Must have taken good leadership, and strong people in healthy bodies.

Indeed we ruled back in the good old viking days.
The fact that we weren't many people is even more impressing then !
Please specify "here"

Forget about Northern France (= Normandy). It was the Viking chief Rolf – or Rollo - who ruled there.
The Danish Viking kings had no control over him.
And also forget about Latvia and Lithuania. We NEVER ruled there. And compared with Estonia of today, we only ruled the northern part of it - or more or less half of it.
But we for more than hundred years ruled over Sweden - and that included the whole of Finland, which were a art of Sweden in those days.

Du er da vist dansker, for det er da direkte oversat! Hahaaaaa - fin joke

I don't think, Denmark is over ruling Europe ... but I do believe "Denmark's citizens and government are over ruled by DF - Dansk Folkeparti.

most of the Nederlands France and all the British islands too.

Sverige???
LOOOL😃

...da Ricardo under EM-triumfen i 1992 i Sverige (fodbold) sagde: "screw down the expectations"
Klassiker 😃😃

Just kidding!
The answer to your question is both a yes and a no. It depends on how you see it, and in what time you refer too.
England was invaded mainly from Normandy, which was at that time an area which was given to a viking chief which made the place a settlement. And at some time some danish laws was introduced in parts of England - the dane law. But that was a set of rules, not a dictation from goverment of denmark. The vikings was a first divided into clans, later working together (norwegians, swedes, Danes etc. when it comes to englang, especially the norwegians was very active at some point) - but again - lots of things have been lost in history as the vikings did not write much down themselves. Maybe Denmark was viking area because we was invaded by swedish people in the past? In order to track you own past and cultures, one might take a look at the viking long boats which was so vital to the viking success.
As for Norway - hmmmm.. the countries was united at some time yes, and some danish kings did things they maybe shouldn't have to the norwegians. So in that way, one can say that denmark "decided" over the area of Norway.
Sweden, some parts of it was part of Denmark yes. But the closest thing to a united kingdom with sweden have been the kalmar union (which included norway). And thus, Sweden was not danish as such.
Northern Germany - Parts of it have been danish yes. But there was an election, and before that many german people moved to the area. And so the outcome was, that they decided to be part of germany.
The danes now consist mainly of the people whose forefathers stayed at home when other vikings went to explore the world - writing history as they went along. So to credit Denmark for that much is maybe a little too much. ;-)

"in what time you refer too." - noget værre grammatisk vrøvl.
"The vikings was a first divided"
"especially the norwegians was very active"
"because we was invaded by swedish people"
"the countries was united at some time " o.s.v. - prøv nu på dansk!!!
I flertal hedder det "were" - ikke "was" - hvor svært kan det være at tale dansk på en dansk hjemmeside?

Eller Sahlinistan efter Mundhar-Monika Sahlin.

the vikings always took a little less tax than the local rulers
so they where not only feared also welcome in some parts off england
If the local rulers cheated and took to much tax -the vikings gave then a sharia treament
off with hands and feets- keept then alive - to show an example.
the swedish vikings are the ones who gave name to russia-we are 2 diffrent german tribes mixed with samic talking people-
sweden is not what it used to be denmark neither

"Im at the end of my period-"
Det skulle parlarmentet partout vide

OK i was wrong -it was offcourse a warning
sorry M.Jelved

superpower today is Germany thanks for the marshall help
