Treaty of Shimonoseki in the context of "Taiwan"

The Qing dynasty ruled over the island of Taiwan from 1683 to 1895. The Qing dynasty sent an army led by General Shi Lang to defeat the Ming loyalist Kingdom of Tungning in 1683. Taiwan was then formally annexed in April 1684.

Taiwan was governed as Taiwan Prefecture of Fujian Province until the establishment of Fujian–Taiwan Province in 1887. The Qing dynasty extended its control of Taiwan across the western coast, the western plains, and the northeast over the 18th and 19th centuries. The Qing government did not pursue an active colonization policy and restricted Han migration to Taiwan for the majority of its rule out of fear of rebellion and conflict with the Taiwanese indigenous peoples. Han migrants were barred from settling on indigenous land, and markers were used to delineate the boundaries of settled areas and mountain dwelling aborigines. Despite Qing restrictions, settlers continued to enter Taiwan and push the boundaries of indigenous territory, resulting in the expansion of Qing borders in Taiwan to encompass all of the western plains and the northeast. The lack of state-sponsored colonial administration led to frequent rebellions by Han settlers. By the end of Qing rule in 1895, Taiwan's ethnic Han population had increased by over two million, with some estimates suggesting over three million, making Hans the majority demographic on the island. Taiwan was ceded to the Empire of Japan with the Treaty of Shimonoseki in April 1895, following the Qing dynasty's defeat in the First Sino-Japanese War.

The island of Taiwan, along with the Penghu Islands, became an annexed territory of the Empire of Japan in 1895, when the Qing dynasty ceded Fujian-Taiwan Province in the Treaty of Shimonoseki after the Japanese victory in the First Sino-Japanese War. After Japanese forces crushed the consequent Republic of Formosa resistance movement, Japan ruled Taiwan for 50 years. Its capital was located in Taihoku (Taipei), the seat of the Governor-General of Taiwan.

Taiwan was Japan's first colony and can be viewed as the first step in implementing their "Southern Expansion Doctrine" of the late 19th century. Japan, which aimed to turn Taiwan into a showpiece "model colony", made efforts to improve the island's economy, public works, industry, cultural Japanization (1937 to 1945), and support the necessities of Japanese military aggression in the Asia-Pacific. Japan established monopolies and by 1945, had taken over all sales of opium, salt, camphor, tobacco, alcohol, matches, weights and measures, and petroleum on the island. Most Taiwanese children did not attend schools established by Japan until primary education was made mandatory in 1943.

The Kwantung Leased Territory (traditional Chinese and Japanese: 關東州; ; pinyin: Guāndōng zhōu; Wade–Giles: Kuan-tung-chou; rōmaji: Kantō-shū) was a leased territory of the Empire of Japan in the Liaodong Peninsula from 1905 to 1945.

Japan first acquired Kwantung from the Qing Empire in perpetuity in 1895 in the Treaty of Shimonoseki after victory in the First Sino-Japanese War. Kwantung was located at the militarily and economically significant southern tip of the Liaodong Peninsula at the entrance of the Bohai Sea, and included the port city of Ryojun (Port Arthur/Lüshunkou). Japan lost Kwantung weeks later in the Triple Intervention and the Qing transferred the lease to the Russian Empire in 1898, who governed the territory as Russian Dalian and rapidly developed infrastructure and the city of Dairen (Dalniy/Dalian). Japan re-acquired the Kwantung lease from Russia in 1905 in the Treaty of Portsmouth after victory in the Russo-Japanese War, continued to rapidly develop the territory, and obtained extraterritorial rights known as the South Manchuria Railway Zone. Japan extended the lease with the Republic of China in the Twenty-One Demands and used Kwantung as a base to launch the Second Sino-Japanese War. The Kwantung Leased Territory ceased to exist following the Surrender of Japan in World War II in September 1945 when the Soviet Red Army began to administer the region until Kwantung and the Lüshun base was handed over to the People's Republic of China on 16 April 1955.

The First Sino-Japanese War (25 July 1894 – 17 April 1895), or the First China–Japan War, was a conflict between the Qing dynasty of China and the Empire of Japan primarily for influence over Korea. In Chinese it is commonly known as the Jiawu War. After more than six months of unbroken successes by Japanese land and naval forces and the loss of the ports of Lüshunkou (Port Arthur) and Weihaiwei, the Qing government sued for peace in February 1895 and signed the unequal Treaty of Shimonoseki two months later, ending the war.

In the late 19th century, Korea remained one of the Qing tributary states, while Japan viewed it as a target of imperial expansion. In June 1894, the Qing government, at the request of the Korean emperor Gojong, sent 2,800 troops to aid in suppressing the Donghak Peasant Revolution. The Japanese considered this a violation of the 1885 Convention of Tientsin, and sent an expeditionary force of 8,000 troops, which landed at Incheon. This army moved to Seoul, seized the Korean emperor, and set up a pro-Japanese government on 23 July 1894 in the occupation of Gyeongbokgung. The Qing government decided to withdraw its troops, but rejected recognition of the pro-Japanese government, which had granted the Imperial Japanese Army the right to expel the Qing's Huai Army from Korea. About 3,000 Qing troops still remained in Korea, and could be supplied only by sea; on 25 July, the Japanese Navy won the Battle of Pungdo and sank the steamer Kowshing, which was carrying 1,200 Qing reinforcements. A declaration of war followed on 1 August.

The Russo-Japanese War (8 February 1904 – 5 September 1905) was fought between the Russian Empire and the Empire of Japan over rival imperial ambitions in Manchuria and the Korean Empire. The major land battles of the war were fought on the Liaodong Peninsula and near Mukden in Southern Manchuria, with naval battles taking place in the Yellow Sea and the Sea of Japan.

Russia had pursued an expansionist policy in Siberia and the Far East since the reign of Ivan the Terrible in the 16th century. At the end of the First Sino-Japanese War, the Treaty of Shimonoseki of 1895 had ceded the Liaodong Peninsula and Port Arthur to Japan before the Triple Intervention, in which Russia, Germany, and France forced Japan to relinquish its claim. Japan feared that Russia would impede its plans to establish a sphere of influence in mainland Asia, especially as Russia built the Trans-Siberian Railroad, began making inroads in Korea, and acquired a lease of the Liaodong Peninsula and Port Arthur from China in 1898. Japan signed the Anglo-Japanese Alliance in 1902, and began offering to recognize Russia's dominance in Manchuria in exchange for recognition of Korea as part of Japan's sphere of influence. However, this was rejected by Russia.

The Triple Intervention or Tripartite Intervention (三国干渉, Sangoku Kanshō) was a diplomatic intervention by Russia, Germany, and France on 23 April 1895 over the terms of the Treaty of Shimonoseki, imposed by Japan on Qing China at the end of the First Sino-Japanese War. The treaty, signed on 17 April, had ceded the island of Taiwan and the Liaodong Peninsula to Japan. In response, the three Western powers advised Japan to renounce the Liaodong Peninsula on the grounds that it would cause instability; Japan, anxious to keep their goodwill, did so by treaty on 8 November. The Japanese public was outraged, especially after Russia obtained a 25-year lease on the peninsula in 1898. The reaction against the Triple Intervention was one of the causes of the Russo-Japanese War of 1904–1905, in which Japan won the Russian lease on the peninsula.

Count Mutsu Munemitsu (陸奥 宗光; August 20, 1844 – August 24, 1897) was a Japanese diplomat and politician. He became Minister of Foreign Affairs in 1890 and worked to revise unequal treaties. He served as plenipotentiary at the peace conference in Shimonoseki after the First Sino-Japanese War.
