About shugo

Shugo (守護), commonly translated as '[military] governor', 'protector', or 'constable', was a title given to certain officials in feudal Japan. They were each appointed by the shogun to oversee one or more of the provinces of Japan. The position gave way to the emergence of the daimyo in the late 15th century, as shugo began to claim power over lands themselves, rather than serving simply as governors on behalf of the shogunate.
