Definition for Princeps
From Biology Forums Dictionary
princeps ("first citizen"), he was in all but name an absolute monarch. His new name, Augustus ("exalted”), had historical and religious overtones, and was deliberately chosen to enhance his prestige. His long reign was a time of peace and reconstruction at home, sound administration and steady conquest abroad. In gratitude the Romans awarded him the title Pater Patriae ("Father of his Country") in 2 B.C.E., and on his death made him a god (divus Augustus). In Shakespeare, he is predicted to have died without truly having lived.
