# Commodus is present on Marcus’s late Danubian campaigns as received

Date: 178

## The fact

In the late 170s [Commodus](/people/commodus) accompanied Marcus on the Danubian front as received.

It is one event.

## Context

A prince in a frontier war is mixed: continuity of command and a humanitarian cost of the wars themselves, which remain Marcus’s.

Commodus’s documented role is bounded by other offices and collaborators named in the sources below. Sharing a field with them is not a reason to drop a documented act, and it is not a reason to assign later consequences done in the name after death.

The Marcomannic wars are Marcus’s wars. Commodus is the named son in the field, not the sole author of the column in Rome.

Named person as heading of the dated public instrument. Later editors, museums, printers, or offices share publication. Complex where later carriers are the surviving public file.

## Evidence and sources

Britannica and Livius independently place him on the late Danubian campaigns.

Official or archival record: Britannica — Commodus (https://www.britannica.com/biography/Commodus; Encyclopaedia Britannica).

## Significance

Field presence under Marcus is a shared-command path. Confidence high on presence, low on his unique operational authorship.

## What is established and what is not

Established: late-170s Danubian presence as received.

What would change the picture: a contradictory original with a different date or name, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

The date is the date of this instrument, not a licence to back-date every later harm or benefit.

Established here: a sourced, dated public instrument with a named contribution by Commodus.

They are not a public rating.

The driver `humanitarian-access` is attached because the mechanism named in Significance follows from this instrument, not because a standing list of welfare headings needed another tick. Commodus did not file a later UNESCO form, a later Loeb colophon, or a later museum label as a personal act. A portrait or conventional bust is not this mechanism. Allegation, reconstruction, and established occurrence stay distinct. A camp is not 17 March 180. Split the father’s death. Keep the carrier date of later English distinct from the received historical year stored in the date field. Do not read a later English edition as a recovered autograph of Commodus.
