What was the Boshin War?

The Boshin War was a civil war fought in Japan from 1868 to 1869 between the ruling Tokugawa shogunate and an imperial coalition seeking to restore political power to the Emperor. Triggered by discontent over the shogunate's handling of Western influence, the conflict ended in an imperial victory and marked the completion of the Meiji Restoration. Despite thousands of casualties, the victorious faction eventually showed clemency to the defeated loyalists and pursued continued modernization.
