Princeps is a Latin word meaning "first in time or order; the first, foremost, chief, the most eminent, distinguished, or noble; the first man, first person". As a title, "princeps" originated in the Roman Republic wherein the leading member of the Senate was designated princeps senatus. It is primarily associated with the Roman emperors as an unofficial title first adopted by Augustus in 23 BC. Its use in this context continued until the reign of Diocletian at the end of the third century. He preferred the title of dominus, meaning "lord" or "master". As a result, the Roman Empire from Augustus to Diocletian is termed the "principate" (principatus) and from Diocletian onwards as the "dominate" (dominatus). Other historians define the reign of Augustus to Severus Alexander as the Principate, and the period afterwards as the "Autocracy".
The princeps senatus was the first member by precedence of the Roman Senate. Although officially out of the cursus honorum and owning no imperium, this office brought conferred prestige on the senator holding it.
The Principate is the name sometimes given to the first period of the Roman Empire from the beginning of the reign of Augustus in 27 BC to the end of the Crisis of the Third Century in 284 AD, after which it evolved into the so-called Dominate.
