The Nara Period was marked by political strife in which the Otomo clan was often involved and in Nagayao no Hen (the Conspiracy of Nagayao), Tabito, who was close to Nagayao, was temporarily transferred to Dazaifu as punishment, while in TACHIBANA no Naramaro no Hen (the Conspiracy of TACHIBANA no Moroe, which involved the son of TACHIBANA no Moroe), Komoro was tortured to death and OTOMO no Kojihi was deported, not to return until after the demise of the Emperor Shotoku.
しかし、奈良時代はとかく政争が多かったが、大伴氏もそれに関わる事が多く、長屋王の変では長屋王と親しかった旅人は事件前後に一時的に大宰府に左遷された程度で済んだが、橘奈良麻呂（橘諸兄の息子）の変では古麻呂は拷問死、大伴古慈悲は流罪(称徳天皇崩御後に復帰。)に処された。
