Deletion of 980s in Denmark

Comment: I suggest we discuss this set as a whole here, since this was the first one nominated.  Does anyone know the formal process for that?  I added some events to this one and to 950s in Denmark.  Easy enough, which suggests a  issue.  Once they have been expanded a bit more and we get a sense for how large they are likely to become, we can perhaps consider a merge as suggested by Carrite
