Angrivarii
The wars began in the last years of the reign of Augustus, first emperor of Rome. Augustus died an old but respected man in the year 14 and was celebrated with much pomp and splendor. He left a document to be read to the senate posthumously, expressly forbidding extension of the empire beyond the Rhine. News of the will was welcomed by the Germans, thinking it gave them a free hand in the region. Germanicus found it necessary to pacify the border, which he did by a combination of scorched earth raids and offers of alliance with Rome - in short, stick and carrot. These raids also kept the army of the lower Rhine distracted from the possibility of mutiny, which had broken out on Augustus's death and only been quelled by concessions and executions.

Julian's troops proclaimed him Augustus in February 360. Constantius did not recognize Julian's claim to the title, but was detained from campaigning against him by Persian raids. Constantius died on 3 November 361 after declaring Julian his successor. Julian was sole emperor from Constantius' death until his own death in 363. This article ends its coverage at Julian's death on June 26, 363. For a further timeline until 426, consult Matthews, John. Western Aristocracies and Imperial Court A.D. 364-425.

A † indicates that a date or an event is uncertain. A superscript S indicates that the manuscript is corrupt, and has been emended to follow Otto Seeck's corrections in his edition of the "Codex Theodosianus". Manuscript details are given in brackets (as "mss. date" or "mss. year", etc.) for all emended texts. Unsourced events are purely conjectural. Note that some are based on triangulation of different sources and can be, as such, somewhat inexact. These cases have been noted.
