It has been pointed out that the Katsuraki clan was involved in the assassination of Emperor Anko; however, there is a record that Emperor Anko was planning to hand over his future affairs to Prince Oshihano, which could mean that there was a compromise between the Emperor Anko (the Ingyo family), and Prince Oshihano (the Richu family) and Katsuraki clan, but Pince Ohatsuse was strongly opposed to this plan and decided to wipe out his opponents, including Emperor Anko.
安康暗殺の背景に葛城氏が直接関与していた可能性も指摘されているが、生前の安康は押磐皇子に後事を託そうとしていたという記述（雄略即位前紀）からすれば、むしろ安康（允恭系）と押磐皇子（履中系）・葛城氏との間には王位継承に関する妥協が成立していて、このことに強く反発した大泊瀬皇子が安康を含む敵対勢力の一掃に踏み切ったと解釈することも出来よう。
