Nice map of fascinating region, especially by showing population density so we are not over-weighting mountains and steppe. However, I could imagine that most people and families in that region are multi-lingual and of mixed ethnicity, so mono-colours may be misleading and accentuate divisions. Cities are often different from villages around. Modern group identities may relate more to preferences for a type of governance, than to old ethnic history. Times change. How would this map look like now, and for example, in 1800?
