Through the Boshin (_??__??_) War of 1868, the Meiji Government tried to defeat the remaining Shogunate powers by the military force, and to build up a new centralized State of the Emperor's rule with the 8th Century Ritsuryo(_??__??_). The mobilization of military powers took the form of dispatching the Chinbushi (Suppressor), and resulted in the forming of the judicial court which actually was none other than the suppressor's office combined with the civil administration, and further in the establishment of Fu (_??_) as one of the three new administrative district divisions of Fu (_??_), Han (_??_), and Ken (_??_).
Hakodate-Fu (Prefectural Government at the District of Hakodate) was established as an executive organization of civil administration for the development of Ezochi (or Hokkaido). But when it was captured by the remaining Shogunate naval force, the Meiji Government mobilized the military power of the Aomoriguchi Suppressor, and succeeded in uniting and strengthening the military powers of the new Government at the district of Hakodate by the decisive victory of the Boshin War.
In order to clarify the historical significance of the establishment of the Hakodate-Fu prefectural government, the present author has studied the Shimizudani Kinkô Monjo (or the Diary and Notes of Mr. Kinkô Shimizudani, who was the prefectural governor of Hakodate-Fu) (in the National Diet Library, at the branch of the documents of Constitutional Government), and discussed the process from the Ansei period to the new Meiji Era, around the years 1854-1869.
