Satchō Alliance
All Three Great Nobles were "samurai" of the Satchō Alliance, and died within a short period of time between 1877 (Meiji 10) and 1878 (Meiji 11). Saigō led the Satsuma Rebellion, the largest uprising against the new Meiji government, and died at the Battle of Shiroyama. Kido died from an unknown illness during the Satsuma Rebellion, and Ōkubo was later assassinated by former "samurai" of the Satsuma Domain for his involvement against the uprising.
