The island of Taiwan, together with the Penghu Islands, became a dependency of Japan in 1895, when the Qing dynasty ceded Taiwan Prefecture in the Treaty of Shimonoseki after the Japanese victory in the First Sino-Japanese War. The short-lived Republic of Formosa resistance movement was suppressed by Japanese troops and quickly defeated in the Capitulation of Tainan, ending organized resistance to Japanese occupation and inaugurating five decades of Japanese rule over Taiwan. Its administrative capital was in Taihoku (Taipei) led by the Governor-General of Taiwan.
