A Preliminary Quantitative Study on the Tenure of the Six Ministries of Nanjing during the Ming Dynasty
The Six Ministers of Nanjing were the highest level of civil officials in the secondary capital during the Ming Dynasty under the dual-capital system,with the Minister of Southern Military being particularly cen-tral to the governance.However,a"longue dur é e"examination reveals that the shortage of Ministers of Nanjing was the norm,with statistics showing an average vacancy period of about 46.57 years,and the position for Minister of Southern Military,being at the core,had the shortest vacancy period.In terms of native place,the geographical distribution of the Six Ministers of Nanjing was more southern-oriented,but the critical Southern Military and Southern Revenue Ministers were exceptions.Under the overall pattern of"more northern in the north,more southern in the south",the hometowns of the two ministry officials were distributed more evenly,resembling that of the Northern Revenue and Northern Military Ministers.This contrast reflects the dual characters of the Six Ministers of Nanjing as both central and local officials,es-sentially highlighting the different levels of consideration and objective needs between national governance and local governance.
