When we knew

Timeline datec. 3400 BCE

Late-fourth-millennium BCE tablets at Uruk (present-day Iraq) recorded numerical accounts and commodities, moving institutional obligations from loose tokens into durable written ledgers.

What changed

Value could be compared or recorded without requiring one universal circulating object.

What came before

Earlier societies already combined material value, obligations, and trust in forms specific to their institutions.

What came after

Later systems reused this capability under different political, material, and technical conditions; the sequence does not imply one universal path.
