Hmm... a Venice with (I assume) much of the Balkans, disunited Leon and Castille, Papal States with Tunisia and northern Algeria, no Switzerland, independent Savoy, Aragon, Genoa, and Milan, and 'Caliphate'. Wait, before I say anything more, what year is the map based on?
England does better in 100 years war.
France never gets it's act together, so Savoy, Genoa, etc, stay independent.
HRE and Normans do worse in Italy. so Pope takes all south Italy/Tunisia.
Hungary [lite brown] remains Austria [Austria migrated westward during early 2nd Millennium]
Byzantines [lite blue] hold Balkans.
No Austria so Vienna [darker blue] remains independent.
HRE [dark brown] never really unites, so Russia gets all of Poland, Denmark [Kalmar] keeps SH.
With no united France, Iberia splits different, when the Muslims never take Spain.
Do the papal states control Scandinavia? Or do they just have the same color?
10th century.
Several of the borders look awfully wrong, specially in Iberia, but The French-UK border does not look so fine either.
And it seems than Aragon has lost, well, Aragon, to Castille...
aragon lost because el cid, a castillian got valencia instead of jacme.
