- Claudius revives the censorship and ludi saeculares, and organises the order of the Haruspices, with 60 members.
- Gnaeus Domitius Corbulo is made commander of the Roman army in Germania Inferior. He conquers the Chauci and fights against the Cherusci and Frisians.
- Cauci pirates led by the Roman deserter Gannascus ravage the Gallic coast; Corbulo uses the Rhine fleet against them. The Frisian revolt is suppressed.
- Publius Ostorius Scapula replaces Aulus Plautius as governor of Britain. The south-east of the island is now a Roman province, while certain states on the south coast are ruled as a nominally independent client kingdom by Tiberius Claudius Cogidubnus, whose seat is probably at Fishbourne near Chichester. Ostorius immediately faces incursions from unconquered areas, which he puts down.
- Corbulo orders the construction of the canal Fossa Corbulonis, between the Rhine and Meuse in the Netherlands, which connects the city Forum Hadriani (Voorburg).
- Romans build the Traiectum fortification near the mouth of the Rhine, which will later grow to be the city of Utrecht.
- Claudius founds the city Forum Claudii Vallensium (modern Martigny) in the Alpes Poeninae (Switzerland).
