magnus maximus

magnus maximus -lrb- , -rrb- -lrb- ca. 335 -- august 28 , 388 -rrb- was western roman emperor from 383 to 388 .
in 383 as commander of britain , he usurped the throne against emperor gratian ; and through negotiation with emperor theodosius i the following year he was made emperor in britannia and gaul -- while gratian 's brother valentinian ii retained italy , pannonia , hispania , and africa .
in 387 maximus ' ambitions led him to invade italy , resulting in his defeat by theodosius i at the battle of the save in 388 .
in the view of some historians his death marked the end of direct imperial presence in northern gaul and britain .
