The Carausian Revolt (286 – 296 AD.) was an episode in Roman history, during which a Roman naval commander, Carausius, declared himself emperor over Britain and northern Gaul. His Gallic territories were retaken by the western Caesar Constantius Chlorus in 293, after which Carausius was assassinated by his subordinate Allectus. Britain was regained by Constantius and his subordinate Asclepiodotus in 296.

Colchester is a city in northeastern Essex, England. It is the second-largest settlement in the county, with a population of 130,245 at the 2021 Census.
Colchester occupies the site of Camulodunum, the first major city in Roman Britain and its first capital. Colchester therefore claims to be Britain's first city.[9][10] It has been an important military base since the Roman era, with Colchester Garrison currently housing the 16th Air Assault Brigade.
Etymologists are confident that the Colne's name is pre-Roman, sharing its origin with several other rivers Colne or Clun around Britain, and that Colchester is derived from Colne and Castra. Ekwall went as far as to say "it has often been held that Colchester contains as first element [Latin] colonia ... this derivation is ruled out of court by the fact that Colne is the name of several old villages situated a good many miles from Colchester and on the Colne. The identification of Colonia with Colchester is doubtful." The earliest forms of the name Colchester are Colenceaster and Colneceastre from the 10th century, with the modern spelling of Colchester being found in the 15th century. In this way of interpreting the name, the River Colne which runs through the area takes its name from Colonia as well.
