For example, in Kanto, Kamakura Kubo (Governor-general of the Kanto region) escaped to Koga-jo Castle and, using the name of Koga Kubo, started a total war with the Uesugi clan that was Kanto Kanrei (a shogunal deputy for the Kanto region) (Kyotoku Disturbance), and Masatomo ASHIKAGA, who was dispatched by the shogun as the successor of Kamakura Kubo, could not enter Kamakura (Horigoe Kubo).
例えば、関東では鎌倉公方が古河城に逃れて古河公方と名乗って関東管領上杉氏との全面戦争（享徳の乱）を引き起こし、将軍が後任の鎌倉公方として派遣した足利政知も鎌倉にさえ入ることができなかった（堀越公方）。
