There were three major changes in the Roman political system. Initially they had a monarch, then a republic and lastly a principate. However during the republic itself, there were changes, such as the granting of civil rights to the plebeians, written laws, an expanding empire which necessitated governorships and provincial officers, and a permanent army to control the borders. After the principate was established there were no more than token elections and all power and authority was consolidated in the emperor.

All Roman emperors had control over the whole of the Roman Empire, except when there were usurper emperors. There were three usurpers in Britain: Carausius (286-93), Magnum Maximus (usurper in Britain and Gaul, 383-84) and Constantine III (usurper in Britain and Gaul, 407-09). There was also a 14 year period when there was a breakaway empire, the Gallic Empire (260-74) which comprised Britain and Gaul and had eight emperors.
