Augustus decreed that at least ten provinces would be held by the authority of the Roman people through the agency of the Senate. Though all ten were "proconsular", only two of these provinces (Asia and Africa), were actually governed by senators with proconsular imperium, the remaining eight being governed by propraetors. The two proconsular governors served for one year, while the eight praetors served typically for up to 3 years. Each of these men had six lictors who served as bodyguards and also as a symbol of authority and a mark of their position.
