A historical title for a high-ranking military or administrative official in pre-modern Japan, roughly equivalent to a governor-general.
惣管領は、室町時代の重要な役職の一つだった。
The governor-general was one of the important posts in the Muromachi period.
The term is composed of 惣 (general, overall), 管 (control, manage), and 領 (territory, jurisdiction). The exact historical derivation is uncertain; it is a conventional title for a high-ranking official.
