In the same year, Pertinax unmasked a conspiracy by two enemies of Cleander. As a result, Commodus appeared even more rarely in public, preferring to live on his estates. Early in 188, Cleander disposed of the current praetorian prefect, and himself took over supreme command of the Praetorians at the new rank of "a pugione" ("dagger-bearer") with two praetorian prefects subordinate to him. Now at the zenith of his power, Cleander continued to sell public offices as his private business. The climax came in the year 190, which had 25 suffect consuls—a record in the 1,000-year history of the Roman consulship—all appointed by Cleander (they included the future Emperor Septimius Severus).
