shogunate

His title to the shogunate was frequently disputed, however, and rival claimants waged fierce war upon him.

It was during the last days of the Shogunate and before the restoration of the Imperial rgime.

This was the very year of the downfall of the Shogunate and the restoration of the imperial power.
