O-Ie Sōdō
Shirakawa was then assigned to Matsudaira (Okudaira) Tadahiro, but he was in poor health and assigned running the domain to his "karō". Furthermore, the early death of his sons led to an "O-Ie Sōdō" which divided his retainers between a faction favoring a son-in-law and a faction favoring a grandson. His inability to resolve this crisis resulted in his demotion and replacement by another branch of the Matsudaira clan.
