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. Emperor Diocletian launches a campaign into Germanic territory from the province of Raetia (Switzerland). 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.
