7. The Kings of _Britain_ were, A.C. 407 or 408, _Marcus_, _Gratian_, and _Constantine_ successively; A.C. 425 _Vortigern_, 466 _Aurelius Ambrosius_, 498 _Uther Pendraco_, 508 _Arthur_, 542 _Constantinus_, 545 _Aurelius Cunanus_, 578 _Vortiporeus_, 581 _Malgo_, 586 _Careticus_, 613 _Cadwan_, 635 _Cadwalin_, 676 _Cadwallader_. The three first were _Roman_ Tyrants, who revolted from the Empire. _Orosius_, _Prosper_ and _Zosimus_ connect their revolt with the irruptions of the _Barbarians_ into _Gallia_, as consequent thereunto. _Prosper_, with whom _Zosimus_ agrees, puts it in the year which began the day after that irruption. The just time I thus collect: _Marcus_ reigned not many days, _Gratian_ four months, and _Constantine_ three years. He was slain the year after the taking of _Rome_, that is A.C. 411, 14 Kal. _Octob._ Whence the revolt was in Spring A.C. 408. _Sozomen_ joins _Constantine_'s expedition into _Gallia_ with _Arcadius_'s death, or the times a little after; and _Arcadius_ died A.C. 408 _May_ the 1st. Now tho the reign of these Tyrants was but short, yet they gave a beginning to the kingdom of _Britain_, and so may be reckoned the three first Kings, especially since the posterity of _Constantine_, viz. his sons _Aurelius Ambrosius_, and _Uther Pendraco_, and his grandson _Arthur_, reigned afterwards. For from the time of the revolt of these Tyrants _Britain_ continued a distict kingdom absolved from subjection to the Empire, the Emperor not being able to spare soldiers to be sent thither to receive and keep the Island, and therefore neglecting it; as we learn by unquestionable records. For _Prosper_ tells us; _A.C._ 410, _Variane Cos. Hac tempestate prae valetudine Romanorum, vires funditus attenuatae Britanniae_. And _Sigebert_, conjoining this with the siege of _Rome_, saith: _Britannorum vires attenuatae, & substrahunt se a Romanorum dominatione_. And _Zosimus_ _lib._ 6. _The _Transrhenane Barbarians_ invading all places, reduced the inhabitants of the island of _Britain_, and also certain _Celtic_ nations to that pass, that they fell off from the _Roman_ Empire; and being no longer obedient to the _Roman_ laws_, [Greek: kat' heauton biateuein], _they lived in separate bodies after their own pleasure. The _Britons_ therefore taking up arms, and hazarding themselves for their own safety, freed their cities from the imminent _Barbarians_. In like manner all _Brabant_ and some other Provinces of the _Gauls_ imitating the _Britons_, freed themselves also, ejecting the _Roman_ Presidents, and forming themselves into a sort of commonwealth according to their own pleasure. This rebellion of _Britain_ and the _Celtic_ nations happened when _Constantine_ usurped the kingdom_. So also _Procopius_, _lib._ 1. _Vandal._ speaking of the same _Constantine_, saith: Constantine _being overcome in battle, was slain with his children:_ [Greek: Bretannian men toi Romaioi anasosasthai ouketi echon; all' ousa hypo tyrannous ap' autou
