The hierarchy served economic purposes—organizing labor, distributing resources, creating productive structure that generated surplus supporting non-agricultural activities.
The Specialization:
Thralls performed basic labor—farming, household work, construction, freeing karls for more skilled activities, allowing jarls to focus on military and political affairs. The specialization was productive—each category doing what they were most suited for, creating efficiency that benefited (primarily) those at top but also generated surplus that supported arts, crafts, trade.
The Exploitation:
The system extracted surplus—thralls worked without compensation, karls paid tribute or provided service, jarls accumulated wealth through controlling others’ labor. The exploitation was systematic—embedded in legal structure, justified by ideology, maintained through violence when necessary, creating wealth concentration that funded raiding fleets, trading expeditions, political maneuvering.
