Yeah,but we don't know anything about the "Albanian predecessor culture",and I don't think the culture would change that drastically between 1066 and the 1070's,so I'd rather just have an Albanian culture represent both things on the map.
EDIT:
I said only said that because people mentioned having the albanian culture appear in an event,I don't even know how you came up with this,seeing that it seems to be the exact opposite of what I'm saying
EDIT2:
I think you mean that we shouldn't erase any cultures preceding the albanian culture,but we don't even know anything about them,so I don't see why just having Albanians be present on the map would be an bad idea.
Bear in mind that there isn't only 1066 to consider. There's also 867, and how whatever is present in those provinces could "naturally" shift to Albanian if it is not already there, whether this is a migration, an evolution of culture, or a cultural melting pot.
We know that at some stage there were Illyrians of some sort there (the 7th century, when various Slavs came into the area and either displaced, assimilated or eliminated them). Then from the mid 9th century to the early to mid 11th we have Bulgarian rulers over this before the land is taken into the Byzantine Empire.
So, potentially what we have is the Albanian culture rising out of either Bulgarian or Greek rulers over whatever Slavic group is seen as being present.
If we're going to see an Albanian culture on the map, how much territory should it hold? Where? What cultures that have already been placed will this affect?
I'm far from against having the culture on the map at 1066 if the situation is unclear, or if the few years wouldn't make a difference, but having them there "from the start" (which is 867) might be a stretch, as might automatically identifying the culture of 867 with the culture of 1066 and beyond.
Ptolemy (2nd century AD) mentions a people called "Albanoi", an Illyrian tribe, living north of Epirus and west of Macedonia. As I've mentioned before, "Albanians" (an exonym), have probably lived in the Western Balkans since prehistoric times. I don't see why there would be an event needed to create them--They're the majority ethnicity of a region, and probably have been for at least 2,000 years.
Given some of the small tribes appearing as specific ethnicities and some of the minor cultural distinctions made elsewhere on the map, I think it's an oversight to make all of the Western Balkans either South Slavic or Greek.
Are you sure those are the same as the Albanians mentioned in 1070, and that it isn't a case of a later cultural identity having adopted the name of an earlier one? The area has been under several different rulers by that point (Romans/Byzantines, Slavs, Bulgars by the 9th century, and then had a prolonged war run through it by the mid 11th when it comes back to the Byzantines).
