Family tree of Roman emperors

This is a family tree of the Roman Emperors, showing only the relationships between the emperors.

The emperors from Augustus to Commodus can be organised into one large family tree with one non-related emperor (Galba).

The emperors from Pertinax to the beginning of the Crisis can be organised into one large dynasty (see Severan dynasty family tree), one smaller family and two unrelated emperors.

The emperors during the fifty-year period of the Crisis can be organised into seven families and seven unrelated emperors, although no family held power for more than fifteen years.

The emperors from the founding of the Dominate in 284, in the West until 476 and in the East until 518, can be organised into one large dynasty plus ten unrelated emperors.
