Emperor Kinmei
Regardless of speculation about Keitai's genealogy, it is well settled that there was an extended period of disputes over the succession which developed after Keitai's death. A confrontation arose between adherents of two branches of the Yamato, pitting the supporters of sons who would become known as Emperor Ankan and Emperor Senka against those who were backers of the son who would become known as Emperor Kinmei.
