Soga clan
At a time when imperial succession was generally determined by clan leaders, rather than the emperor, Suiko left only vague indications of succession to two candidates while on her deathbed. One, Prince Tamura, was a grandson of Emperor Bidatsu and was supported by the main line of Sogas, including Soga no Emishi. The other, Prince Yamashiro, was a son of Prince Shōtoku and had the support of some lesser members of the Soga clan. After a brief struggle within the Soga clan in which one of Prince Yamashiro's main supporters was killed, Prince Tamura was chosen and he acceded to the throne as Emperor Jomei in 629.
