Valentinian extends Roman fortifications on the south bank of the Danube into the territory of the Quadi, who have remained peaceful since their settlement in Dacia in 359.

In 375, Gabinus, king of the Quadi, leads a force to one of the region's principal forts to complain of this territorial violation, but the fort's commander murders him for presuming to challenge Rome.
