Comes Britanniarum

The (Latin for "Count of the Britains") was a military post in Roman Britain with command over the mobile field army from the mid-4th century onwards. It is listed in the List of Offices as being one of the three commands in Britain, along with the Dux Britanniarum and the Comes litoris Saxonici. His troops were the main field army (comitatenses) in Britain and not the frontier guards (limitanei) commanded by the other two. Appointment Archaeologists Timothy W. Potter and Catherine Johns believe that the Comes Britanniarum led an ad hoc force created to deal with a particular situation. They seem to have been appointed during times of crisis. It appears the title was temporary and did not remain for long, and certainly did not have the permanence of the Dux Britanniarum and the Comes litoris Saxonici, but for the duration of the crisis the Comes Britannarum had chief command of Roman military forces in Britain. The first "Count" in Britain was Gratianus Funarius, the father of emperor Valentinian I. He may have commanded a task force of comitatenses under emperor Constans during his campaign on the island in the winter of 342–3. During the Great Conspiracy, Count Theodosius, the father of emperor Theodosius I, also served as "Count" in Britain. A permanent office was created later in the fourth or early fifth century, perhaps by Stilicho who withdrew troops from Britain to defend Italy in 402.
