Constantine II was Constantine I second son. Repeatedly sent over to the West to deal with military emergencies, he inherited Gaul, Spain, and Britain at Constantine's death in 337. Not content with this much he first entered a conspiracy with his two brothers and eliminated the Caesars, their cousins. With the Caesars out of the picture, frictions now rose between the Augusti. A conference in 338 failed to settle the matters between them, and in 340 Constantine decided he was strong enough to wrestle Rome from his brother Constans I, who refused to acknowledge him as senior August. The expedition turned a disaster, for the vanguard forces sent by Constans to halt his progress surprised the unwary Constantine II and killed him as his army was descending into Italy.
