源頼家
In 1202 Minamoto no Yoriie became "shōgun" at the age of 18. Real power remained with his grandfather, Hōjō Tokimasa and his mother Masako. Yoriie married Wakasa no Tsubone, the daughter of Hiki Yoshikazu a general and warrior upon whom he relied heavily. Soon after, Wakasa gave birth to a boy named Ichiman, who should have been the legitimate successor to the shogunate. Tokimasa invited over Hiki Yoshikazu for peace talks and then had him assassinated and his house burned to the ground in 1203.
