Beyond settling disputes, Thing made communal decisions about leadership, military action, religious matters, anything affecting collective welfare.
The Leadership:
Leaders were acknowledged or challenged at Thing—chieftains maintained position through continued support, could be replaced if they lost confidence, faced questioning about decisions made. The system provided accountability—leaders who failed to maintain followers’ loyalty lost position, making leadership contingent on performance rather than hereditary right (though heredity provided initial advantage that still required validation through competence).
The Military Decisions:
Declaring war, planning raids, organizing defense—these required communal agreement achieved through Thing. The assembly decided whether to commit resources to military action, who would lead expedition, how plunder would be divided. Individual warriors might pursue personal raids, but major campaigns needed broad support achieved through Thing deliberation.
The Religious Matters:
When Christianity arrived, Thing became venue for debating and deciding on religious conversion—most famously at Iceland’s Alþingi in 1000 CE when the assembly decided that Iceland would officially adopt Christianity while allowing private practice of old religion. This demonstrated Thing’s authority even over religious matters, making theological questions subject to communal political decision.
