Later campaign narratives imply army crowding as a disease fact of the Saxon and Italian marches
Crowding and camp disease are a low-confidence transmission path. Do store campaign crowding as later readers meet it. In the causal graph this event strengthens Infectious-Disease Transmission, a driver that weakens Life expectancy at birth — a worsening welfare path.

Read the full account
Einhard and annals as later English describe large seasonal armies. Crowding and camp disease are a low-confidence transmission path. He did not write an epidemiology tract.
Context
Do store campaign crowding as later readers meet it.
Charlemagne is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.
Why it matters
Printed host-mustering is not a modern outbreak table.

Named Frankish king-emperor as heading of later annals, coins, and prizes. Scribes, popes, and later cities publish the instrument.
