The rule of the early Roman emperors, during which some features of republican government were retained.
- ‘Piso had been accused of complicity in the death of Germanicus, the heir apparent of Tiberius [emperor 14-37 A.D.], in one of the causes célèbres of the early principate.’
- ‘They were also the armies which they and other commanders turned against each other in the civil wars which destroyed the republic and led to the establishment of a principate under Caesar's adopted son, Augustus.’
- ‘Instead of following Caesar's example, however, and making himself dictator, Octavian in 27 BC founded the principate (from princeps, ‘the leading man’), a system of monarchy headed by an emperor holding power for life.’
- ‘Although Augustus cleverly refused all titles but principate, the Romans did make a god of him after death.’
Late Middle English (denoting a principality): from Latin principatus first place from princeps, princip- first, chief (see prince). The sense rule of the emperors dates from the mid 19th century.
