December 297 CE
Lucius Domitius Domitianus revolts against Diocletian in 297, seizing power for a short time in Aegyptus province, but dies in December of the same year, when Diocletian goes to Aegyptus to quell with the revolt.
Numismatic and papyrological evidence support Domitianus' claim for the purple.
It is possible that the rebellion had been sparked by a new tax edict, but this uncertain.
