In 1433, Yoshinori accepted 12 conditions issued by Hieizan Enryaku-ji Temple but, outraged when monks nonetheless started rioting, led his army in an attack on the temple, forcing it to surrender and accept a ceasefire; however, the following year, Yoshinori received a report from Mochiuji ASHIKAGA that the temple was placing a curse on him, leading him to again send troops and behead several high priests, and in March 1435, the temple's cornered monks immolated themselves.
ところが1433年（永享5年）に比叡山が幕府に十二か条からなる要求を行い、義教は応じたものの、それにもかかわらず僧兵が暴動を起こすに至って激怒し自ら兵を率いて比叡山を攻撃、比叡山側は降伏して一旦は停戦するものの翌年には足利持氏の依頼で義教を比叡山が呪詛しているとの報を受けるに及んで再び出兵、比叡山の高僧を数人斬首するに至り、やがて1435年（永享7年）2月には比叡山僧侶を焼身自殺に追い込んだ。
