In the mid-4th century there were increasing raids on Roman Britain by peoples such as the Picti, Scotti, Attacotti and Franks, as well as the Saxons. In 367, these tribes simultaneously invaded Britain from the north, west and east. The invaders reportedly defeated or co-opted Roman forces in most parts of northern and western Britain. However, the Roman general Theodosius had recaptured most areas by the end of 368. In 380–1, Magnus Maximus defeated further raids. However, there was increasing internal conflict across the Roman Empire. During 383–4, in the context of the overthrow of Emperor Gratian, Maximus took most of the garrison from Britain to Gaul, where he was made Augustus of the West, ruling Britain, Gaul, Spain and Roman Africa. Following the death of Maximus in 388, Roman authority in Britain again declined. During the late 390s, Stilicho attempted to restore control, with a campaign against the Picti, but this was undermined in 401 when Stilicho transferred troops to the Continent to fight the Goths. Two subsequent Roman rulers of Britain were murdered. In 407, a Roman officer in Britain, Constantine III declared himself Augustus of the West, and left for Gaul, taking with him Roman troops. Finally, in 410, when Romano-British officials requested military assistance from Emperor Honorius, he told them to manage their own defences. Economic decline occurred after these events: circulation of Roman coins ended and the importation of items from the Roman Empire stopped.
