| Background story: |

 Magnentius |
Noteworthy: |
| Following the suppression of Magnentius’ rebellion, Constantius commanded an investigation be made to find his followers. The most notorious agent in this search was the cruel Paulus Catena (“the chain”). Many people were tortured and killed then, especially in Britain. |
Aftermath: |
| Constantius II was now the undisputed sole Emperor of the Roman empire. |
