Impact of Jinshin War on Politics and Religion

On 24/07/0672, the Jinshin War, a succession conflict in Ancient Japan, reached its निर्णing phase as forces loyal to Prince Ōama secured victory over those of his nephew, Prince Ōtomo. The conflict began after the death of Emperor Tenji, when rival claims to the throne led to a military confrontation between the two factions. Prince Ōama, who had previously withdrawn from court politics and taken religious vows, mobilized support from eastern provinces and advanced toward the capital. By late July 672, decisive engagements shifted the balance in favor of Ōama’s forces. Historical sources such as the Nihon Shoki record that Prince Ōtomo’s position weakened rapidly as key allies defected or were defeated. Facing imminent defeat, Ōtomo died shortly thereafter, bringing the conflict to an end. Prince Ōama subsequently ascended the throne as Emperor Tenmu, consolidating control over the imperial court and its territories. The outcome of the Jinshin War led to administrative and political changes that strengthened centralized rule. Under Emperor Tenmu’s leadership, efforts were made to reorganize government structures, reinforce imperial authority, and formalize systems of law and rank. These developments contributed to the gradual transition from clan-based power toward a more centralized imperial state during the late 7th century.
