It is said that after Hideyoshi's failure to accomplish his desire to become 'Seii Taishogun', he introduced a new system, 'the Kanpaku system by the samurai family' instead of the 'Bakufu' system; the status of 'Kanpaku' was given to him through accidental events, and he tried to change the status to the Toyotomi-clan hereditary system (by excluding five Fujiwara Gosekke (five top Fujiwara families whose members were eligible for the positions of Sessho and Kanpaku)).
また、秀吉は当初は征夷大将軍への就任に意欲を示したとも言われているが実現せず、代わって偶発的事情から得た関白の地位を武家である豊臣氏による世襲制度（公家である藤原氏の五摂家を排除）に変更して、幕府制度に代わる武家関白制（ぶけかんぱくせい）とも言うべき体制を導入しようとしたと考えられている。
