Original prompt & settings (JSON) ↗Rome got a new emperor who was not in Rome — and who did not rush back to stage an accession.
An heir already on the Rhine
Nerva's principate ended with his death in Rome on the conventionally accepted date of 27 January 98. Cassius Dio's epitome gives its length as one year, four months and nine days.
Because Nerva had publicly adopted Trajan in October 97 and associated him with imperial power, Trajan became emperor with no competitive election and no civil war. He was away with the German armies at the time — ancient accounts describe him as governor or commander there.
A letter, not a ceremony
Cassius Dio records that the new emperor sent the Senate a letter promising not to kill or disenfranchise any good man.
Trajan did not hurry to Rome. The peaceful handover also had an ugly prehistory: Praetorian guards had mutinied in 97 and forced Nerva's hand before he chose a soldier-heir.
How firm is the date, and what did not happen on it
Recent Oxford scholarship dates the end of the reign to 27 January 98, but older chronologies give 25 January and some reference works begin Trajan's reign on 28 January.
The circumstantial story — a stroke first, then a fever, in the Gardens of Sallust — is widely repeated by modern references but is less securely supported than the plain facts of Nerva's death at Rome and Trajan's succession.
Trajan's eventual entry into Rome, his welfare measures, conquests, building program and canal work were not events of 27 January 98.

What the sources leave uncertain
- Recent Oxford scholarship dates the end of Nerva's reign to 27 January 98, but older chronologies give 25 January and some reference works begin Trajan's reign on 28 January.
- Cassius Dio's surviving epitome supplies a reign length rather than a modern calendar date.
- The detailed story that Nerva first suffered a stroke and then died of fever in the Gardens of Sallust is repeated by modern references but is less securely supported than the basic facts of his death in Rome and Trajan's succession.
- Trajan's precise location is commonly given as Cologne, but the firmer ancient evidence establishes only that he was away with the German command.
