Hatakeyama Yoshitsugu was the head of the Hatakeyama Clan.
Yoshitsugu begged Date Terumune to rein in on his son Date Masamune's campaigns of terror that were massacring the Hatakeyama people. Terumune was kidnapped by the Hatakeyama in a meeting, and the young Masamune killed his father and everybody in the castle. Masamune then campaigned against the kidnappers. Yoshitsugu commanded a large field army against the Date, but was defeated and killed.
