Evolution of Societies through Integration

The conversion of rulers like Rallo to Christianity could lead to a shift towards centralized hierarchies, reducing individual freedom. Additionally, Viking advantages in war could diminish as they settle in new lands, losing mobility. Over time, the Scandinavian settlers became absorbed into the societies they conquered, creating a blended society. The integration and fusion of diverse groups of people into a cohesive whole are highlighted, resembling the concept of 'out of many, one.'
