1870–77: Pan-Asian War.
The Ottoman Empire was bitter over the slow losses of its territory, and wanted to reclaim its lands from Russia and the Domination. Persia had been fighting a slow, losing battle of attrition against Russia, and has been supporting the Uigur rebels. The Maratha were rabidly pro-Hindu and pro-caste system. They razed mosques and killed any Muslim clerics who dared claim equality between untouchable and Brahmin. In China, the Emperor claimed Turkestan as part of "The Heavenly Kingdom." Also the religious claims made by this "Mahdi" were in direct conflict with those of Emperor Hung Hsiu Chuan, and there are border clashes in Manchuria with Russia. The three sides thus became Russia and Domination vs. Ottoman Empire and Persia vs. Taiping China and Maratha India and Satsuma Japan.
The war began as a series of border clashes between Russia and the Ottoman Empire, but quickly grew into a miniature world war. The Domination invaded Turkey. In Japan, the Satsuma bowmen defeat the Choshu musketeers, and the Satsuma Rebellion is successful. The Japanese (mostly Samurai) then proceeded to invade Sakhalin Island and attack Vladivostok.
