Empire of JapanThe Empire of Japan or Japanese Empire, also referred to as Imperial Japan, was the Japanese nation-state that existed from the Meiji Restoration in 1868 until the enactment of the reformed Constitution of Japan in 1947. From 29 August 1910 until 2 September 1945, it administered the naichi (the Japanese archipelago and post-1943 Karafuto) and the gaichi (Korea, Taiwan, Kwantung Leased Territory, and pre-1943 Karafuto). The South Seas Mandate was a single Japanese dependent territory in the name of the League of Nations.
Boxer RebellionThe Boxer Rebellion, also known as the Boxer Uprising, the Boxer Insurrection, or the Yihetuan Movement, was an anti-foreign, anti-colonial, and anti-Christian uprising in China between 1899 and 1901, towards the end of the Qing dynasty, by the Society of Righteous and Harmonious Fists (Yìhéquán). The rebels were known as the "Boxers" in English because many of its members had practised Chinese martial arts, which at the time were referred to as "Chinese boxing".
Yalu RiverThe Yalu River (), known by Koreans as the Amrok River or Amnok River, is a river on the border between China and North Korea. Together with the Tumen River to its east, and a small portion of Paektu Mountain, the Yalu forms the border between China and North Korea. Its valley became the scene of several military conflicts in the past centuries. The Korean name Amnok (압록,鴨綠) is most likely derived from ancient Koreanic language of Goguryeo.
Yellow SeaThe Yellow Sea is a marginal sea of the Western Pacific Ocean located between mainland China and the Korean Peninsula, and can be considered the northwestern part of the East China Sea. It is one of four seas named after common colour terms (the others being the Black Sea, the Red Sea and the White Sea), and its name is descriptive of the golden-yellow color of the silt-ridden water discharged from major rivers.
TaelTael (ˈteɪl), also known as the tahil and by other names, can refer to any one of several weight measures used in East Asia and Southeast Asia. It usually refers to the Chinese tael, a part of the Chinese system of weights and currency. The Chinese tael was standardized to 50 grams in 1959. In Hong Kong and Singapore, it is equivalent to 10 mace () or catty, albeit with slightly different metric equivalents in these two places. These Chinese units of measurement are usually used in Chinese herbal medicine stores as well as gold and silver exchange.
East AsiaEast Asia is the easternmost region of Asia, which is defined in both geographical and ethno-cultural terms. The modern states of East Asia include China, Japan, Mongolia, North Korea, South Korea, and Taiwan. Hong Kong and Macau, two small coastal quasi-dependent territories located in the south of China, are officially highly autonomous but are under Chinese sovereignty. Japan, Taiwan, South Korea, Mainland China, Hong Kong, and Macau are some of the world's largest and most prosperous economies.
JoseonJoseon (; tɕo.sʌn), officially Great Joseon (; tɛ.tɕo.sʌn.ɡuk̚), was the last dynastic kingdom of Korea, lasting just over 500 years. It was founded by Yi Seong-gye in July 1392 and replaced by the Korean Empire in October 1897. The kingdom was founded following the aftermath of the overthrow of Goryeo in what is today the city of Kaesong. Early on, Korea was retitled and the capital was relocated to modern-day Seoul. The kingdom's northernmost borders were expanded to the natural boundaries at the rivers of Amrok and Tuman through the subjugation of the Jurchens.
IncheonIncheon (; intɕhʌ̹n; or Inch'ŏn; literally "kind river"), formerly Jemulpo or Chemulp'o (제물포) until the period after 1910, officially the Incheon Metropolitan City (인천광역시, 仁川廣域市), is a city located in northwestern South Korea, bordering Seoul and Gyeonggi to the east. Inhabited since the Neolithic, Incheon was home to just 4,700 people when it became an international port in 1883. Today, about 3 million people live in the city, making it South Korea's third-most-populous city after Seoul and Busan.
Torpedo boatA torpedo boat is a relatively small and fast naval ship designed to carry torpedoes into battle. The first designs were steam-powered craft dedicated to ramming enemy ships with explosive spar torpedoes. Later evolutions launched variants of self-propelled Whitehead torpedoes. These were inshore craft created to counter both the threat of battleships and other slow and heavily armed ships by using speed, agility, and powerful torpedoes, and the overwhelming expense of building a like number of capital ships to counter an enemy's.
Russo-Japanese WarThe Russo-Japanese War (Nichiro sensō; Rússko-yapónskaya voyná) was fought between the Empire of Japan and the Russian Empire during 1904 and 1905 over rival imperial ambitions in Manchuria and the Korean Empire. The major theatres of military operations were in Liaodong Peninsula and Mukden in Southern Manchuria, and the Yellow Sea and the Sea of Japan. Russia sought a warm-water port on the Pacific Ocean both for its navy and for maritime trade.
