蜀漢的都督

Du Du (A war zone Commander) of Shu Han Kingdom

督軍事源起於東漢末年之征討賊寇，事訖即罷。三國鼎立，長期對峙，督某地區軍事遂由臨時派遣而成長期任務，並逐漸演變成正式官制。蜀漢政權也因應軍政形勢的需要在各地設置都督區，歷來常以庲降、漢中、江州、永安四大都督區並論。但各督區設置的戰略考量不一，遂有不同的發展。庲降都督鎮守南中，以和撫為目標，戰略長期穩定，庲降都督是一新設的官稱。漢中督區地處蜀魏前線，或攻或守，或由重將或由執政屯駐，統帥身分異於其它督區，督漢中軍事是其最重要的任務，但並非正式官稱。江州、永安東備孫吳，但兩地常有隸屬關係，應視為一督區。後主後期，姜維屢次進出隴西，武都、陰平亦見諸多督區。

To command some local military affairs originated from Shun Emperor(順帝) of Eastern Han Dynasty. It was originally a temporary duty, and discharged after a punitive expedition is completed. Because of long-term oppositions among three kingdoms, the temporary duty gradually evolves into an official position. Shu Han Kingdom also establishes its war zone commander in each place in accordance with the needs of the military administration situation. There are Laisiang(庲降), Hanzhong(漢中), Jiangzhou(江州) and Yongan (永安) four big war zones. Each war zone was established for its strategic considerations, therefore also had the different evolution. Laisiang Du Du (庲降都督) was a new officer name, the war zone commander to be responsible for the defense duty toward south, and adopted the strategy of stability during the whole period. Since the Hanzhong(漢中) war zone sat at the front line between Shu Han Kingdom(蜀漢) and Wei Kingdom(魏), their tactic alternated between offense and defense every now and then, and their commander was not only an important military officer, but sometimes holds the post by governor. It is quite different from other war zones. Jiangzhou(江州) and Yongan (永安) two zones were originally supposed to defend Wu Kingdom(吳), but both their commanders were mutual subordination, they are actually one war zone. At latter period of the Last Emperor(後主), Jiang Wei(姜維) invaded Longxi(隴西) repeatedly. And then many new war zones appeared at the frontier e.g. Wudu(武都), Yinping(陰平) In northwest.
