As a background of the special description on this incident in the Azuma Kagami compiled by the Hojo clan of Kamakura bakufu in later years, there seemed an intention to expose Yoriie's high-handed manner and justify the connection between the Hojo clan and the Adachi clan since the period of Yoritomo and Masako and also justify the Adachi clan's separation from the Yoriie's power with the support from the Hiki clan, the family home of Kagemori's mother.
鎌倉幕府北条氏による後年の編纂書『吾妻鏡』にこの事件が特筆されている背景には、頼家の横暴を浮き立たせると共に、頼朝・政子以来の北条氏と安達氏の結びつき、景盛の母の実家比企氏を後ろ盾とした頼家の勢力からの安達氏の離反を合理化する意図があるものと考えられる。
