Pertĭnax in Harpers Dictionary of Classical Antiquities

A Roman emperor who ruled from January 1 to March 28, A.D. 193, having been reluctantly persuaded to accept the Empire on the death of Commodus. But having attempted to check the license of the Praetorian Guards, he was slain by the latter, who then put up the Empire for sale. See Capitolin. Pertinax; and Krakauer, Commodus und Pertinax (Breslau, 1883).
