The "Nan-taihei-ki" mentioned that Ietoki ASHIKAGA, who was the seventh generation son after Yoshiie, could not achieve it during his lifetime, so, in a letter, he wished the third generation after him would conquer Japan and then committed suicide.
義家から七代目にあたる足利家時は、自分の代では達成できないため、三代後の子孫に天下を取らせよと祈願し、願文を残して自害したと『難太平記』にある。
