The dated carrier is the modern English Dio, not a 175-01-01 ISO file. In the causal graph this event strengthens Political Polarization, a driver that weakens Having a say in government — a worsening welfare path.

Loeb/LacusCurtius Dio transmits Avidius Cassius’s usurpation in the East, conventionally 175 CE, and the aftermath in Marcus’s name. The dated carrier is the modern English Dio, not a 175-01-01 ISO file.

Context

A civil-military split in a plague-and-war empire is a polarisation path. Later stories of Faustina’s role stay disputed and are not upgraded to autograph.

Marcus Aurelius 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

A revolt in Dio is not a party system. It is still a succession shock.

What the sources establish

Later competitions, monuments, translations, UNESCO listings, and museums are not converted into extra lifetime acts. That reading is an impact-path choice, not a property stored on the Fact itself. Confidence is stated on the impact path. A later English edition is not a recovered autograph. If a number is not in the two records named above, it is not supplied here.
