This siliqua, roughly the equivalent of a reintroduced argenteus, was issued under the usurper Magnus Maximus. A Roman general stationed in Britannia, he instigated a rebellion there, and even moved through Italy, driving out the western emperor, Gratian, and killing him. Due to the threats from tribes in his territory, the eastern emperor, Theodosius I, determined fighting Maximus an unworthy expense. However, after the primary focus of his attention, the Persians, had been brought into treaty, Theodosius acted, and in 388 CE, he defeated Maximus and had him killed. He would then take on both halves of the empire himself, becoming the last ruler of both before their final split into the Byzantine Empire. KHK.
