The early Qing emperors adopted the bureaucratic structures and institutions from the preceding Ming dynasty but split rule between Han Chinese and Manchus, with some positions also given to Mongols. Like previous dynasties, the Qing recruited officials via the imperial examination system, until the system was abolished in 1905. The Qing divided the positions into civil and military positions, each having nine grades or ranks, each subdivided into a and b categories. Civil appointments ranged from attendant to the emperor or a Grand Secretary in the Forbidden City (highest) to being a prefectural tax collector, deputy jail warden, deputy police commissioner or tax examiner. Military appointments ranged from being a field marshal or chamberlain of the imperial bodyguard to a third class sergeant, corporal or a first or second class private.
