Principate

1996, Clare Krojzl (translator), Sebastian Hensel, III: From Diocletian to Alaric [1886, lecture notes], Theodor Mommsen (editor), A History of Rome Under the Emperors, C.H.Beck'sche Verlagsbuchhandlung, Republished 2005, Taylor & Francis (Routledge), eBook, page 317, The dominate of Diocletian and Constantine differs more sharply from the principate than the latter does from the Republic.

The history of the courts and of judicial procedure during the principate is closely parallel to that of the government as a whole.

The transition from republic to Principate brought a new and potent factor into the legal picture of the Roman state, the princeps or emperor.

In the introductory chapter I had already started to examine how Tacitus' designation of the Augustan regime as a versus status potentially draws a line of continuity between the principate and the civil wars which that regime claims to have resolved.

1998, Annabel S. Brett (translator and editor), William of Ockham, On the Power Of Emperors and Popes, Thoemmes Press, page 87, From all this we may draw the conclusion that papal principate was instituted for the utility and advantage of its subjects and not for the honour and glory or the utility and temporal advantage of the holder of the principate, in such a way as that such principate deserves to be called 'of service' and not of 'lordship'.
