Roman Empire

On the same day that he is made consul, Maximian launches a campaign against an invasion of Gaul by the Alemanni. After defeating this invasion, he then invades Alemannia itself, entering across the Upper Rhine and returning to Roman territory via the Upper Danube.
Around this time, the future emperor Constantius defeats and captures a Germanic king, the latter having prepared an ambush against the Romans.
Diocletian signs a peace treaty with King Bahram II of Persia, and installs the pro-Roman Arsacid Tiridates III as king over the western portion of Armenia.
Diocletian re-organizes the Mesopotamian frontier, and fortifies various locations including the city of Circesium (modern Busayrah) on the Euphrates. Around this time, he begins the construction of the Strata Diocletiana. Throughout his reign, similar fortification efforts are conducted on the other frontiers as well, with fortifications constructed or restored behind, on and beyond the borders. Conscription and the number of legions increase, although the legions themselves are reformed into smaller and more flexible units. At some point in time, Diocletian may have also established the late Roman military system of Comitatenses (field army units) and Limitanei (border units), but some scholars date this development to the reign of Constantine I (r. 306–337).
September – The first Indiction begins.

288

By place

Roman Empire

Emperor Diocletian launches a campaign into Germanic territory from the province of Raetia (Switzerland).
Around this time, an army loyal to Maximian, probably led by the future emperor Constantius, defeats the usurper Carausius or his Frankish allies in northern Gaul. In this or the following year, Carausius withdraws his military forces and administrative presence from Gaul, confining himself to Roman Britain.
Maximian makes an alliance with the Frankish king Gennobaudes.
Far from Carausius' fleet, in the rivers of Gaul, Maximian builds a fleet to contest control of the North Sea and re-take Britain.
Around this time, Constantius marries Maximian's stepdaughter, Theodora, and it may also be around this time that the general Galerius marries Diocletian's daughter Galeria Valeria.
