In the Kamakura bakufu (Japanese feudal government headed by a shogun) from about 1283, the rule of naming the Shogun from the Imperial family as "Kubo," "Gokenin" (an immediate vassal of the shogunate in the Kamakura and Muromachi through Edo periods) as "Kubo no hitobito" (Kubo people), and "Kanto Goryo" (the Shogun's demesne) as "Kubo Goryo" was adopted in consideration of such names as Tokuso (the patrimonial head of the main branch of the Hojo clan), Miuchibito (private vassals of the tokuso), and "Miuchi Goryo" (Tokuso's demesne) in the Hojo regency.
更に鎌倉幕府においても弘安6年（1283年）頃より、執権北条氏の得宗・御内人・御内御領に対抗して、皇族将軍を「公方」・御家人を「公方人々」・関東御領を「公方御領」と呼称する規定が成立する。
