Synod of Milan
But the Synod of Milan here alluded to is placed about the year 345, soon after the Synod of Sardica. St. Maximinus was at this synod and this council was convened at Milan in the newly erected Basilica Nova. The council however did not follow the hopes of the Pope due to the number of Arians bishops. The bishop of Milan Dionysius initially seemed ready to follow the Arians in condemning Athanasius, accused not of heresy, with the arrival of Eusebius the situation changed, Eusebius requested an immediate subscription of the Nicaean faith by the bishops. Eusebius and Dionysius signed, but the Arian bishop Valens of Mursia violently shreded the act of faith, unaccustomed to independence on the part of the bishops, moved the synod to his palace and grievously maltreated the papal embassy. Hilary was flogged and the exiled along with Pancratius and the two Nicaean bishops, the synod, now governed by the Arians bishops of the court of Constantius, ended supporting Arian statements. Augustines On the Good of Marriage was written against somewhat that still remained of the heresy of Jovinian and he mentions this error in b. ii. c.
Jovinianus, he says, who a few years since tried to found a new heresy, said that the Catholics favored the Manichæans and that heresy took its rise from one Jovinianus, a monk, in our own time, when we were yet young. And he adds that it was soon overborne and extinguished, say about A. D.390, having been condemned first at Rome, at Milan. There are letters of Pope Siricius on the subject to the Church of Milan, jerome had refuted Jovinian, but was said to have attempted the defense of the excellency of the virgin state, at the expense of condemning marriage. St. Maximus of Turin was at a synod of Milan in 389 at which Jovinianus was condemned, among nineteen subscribers Maximus is the eighth, and since the order was determined by age, Maximus must have been about seventy years old. A synod that took place in Milan in 860 summoned Ingiltrud, wife of Boso, Pope Nicholas I commanded the bishops in the dominions of Charles the Bald to excommunicate her unless she returned to her husband. As she paid no attention to the summons, she was put under the ban, Milan as an early center of Christianity
End of Roman rule in Britain
The end of Roman rule in Britain was the transition from Roman Britain to post-Roman Britain. Roman rule ended in different parts of Britain at different times, in 383, the usurper Magnus Maximus withdrew troops from northern and western Britain, probably leaving local warlords in charge. Honorius was fighting a war in Italy against the Visigoths under their leader Alaric. No forces could be spared to protect distant Britain, though it is likely that Honorius expected to regain control over the provinces soon, by the mid-6th century Procopius recognised that Britannia was entirely lost to the Romans. By the early 5th century, the Roman Empire could no longer defend itself against either internal rebellion or the threat posed by expanding Germanic tribes in Northern Europe. This situation and its consequences governed the eventual permanence of Britains detachment from the rest of the Empire, in the late 4th century, the empire was controlled by members of a dynasty that included the Emperor Theodosius I.
These internal machinations drained the Empire of both military and civilian resources, many thousands of soldiers were lost in battling attempted coups by figures such as Firmus, Magnus Maximus and Eugenius. The crossing of the Rhine caused intense fear in Britannia, prone as it was to being cut off from the Empire by raids on the primary route from Italy. In the event, this was more than just another raid. In 383, the Roman general assigned to Britain, Magnus Maximus, launched his bid for imperial power. He killed the Western Roman Emperor Gratian and ruled Gaul and Britain as Augustus and these outposts may have lasted into the 390s, but they were a very minor presence, intended primarily to stop attacks and settlement by groups from Ireland. In the De Excidio et Conquestu Britanniae, written c, raids by Saxons and the Scoti of Ireland had been ongoing in the late 4th century, but these increased in the years after 383. There were large-scale permanent Irish settlements made along the coasts of Wales under circumstances that remain unclear, Maximus campaigned in Britain against both the Picts and Scoti, with historians differing on whether this was in the year 382 or 384.
Welsh legend relates that before launching his usurpation, Maximus made preparations for an altered governmental, figures such as Coel Hen were said to be placed into key positions to protect the island in Maximus absence. As such claims were designed to buttress Welsh genealogy and land claims, in 388, Maximus led his army across the Alps into Italy in an attempt to claim the purple. The effort failed when he was defeated in Pannonia at the Battle of the Save and he was executed by Theodosius. When Theodosius died in 395, his 10-year-old son Honorius succeeded him as Western Roman Emperor, the real power behind the throne, was Stilicho, the son-in-law of Theodosius brother and the father-in-law of Honorius. He may have ordered campaigns against the Scoti and Saxons at the same time, in 401 or 402 Stilicho faced wars with the Visigothic king Alaric and the Ostrogothic king Radagaisus
