Asia Pacific 1905: Russo-Japanese War

Japan swiftly overran Korea and southern Manchuria, capturing Port Arthur after a prolonged siege. In an attempt to gain naval supremacy, Russia sent its European fleet halfway around the world - only to have the Japanese destroy it at Tsushima. Unsuccessful in the war and facing widespread unrest at home, the Russians sued for peace.


Treaty Ports

Treaty ports - the small unlabelled circles on the map - were towns opened to foreign trade by unequal treaties in China, Japan, and Korea. Foreigners operating within treaty ports enjoyed extraterritoriality, being subject to their home country's laws. Unlike concessions such as Hong Kong, these territories were not directly leased by the foreign powers and did not have sizable foreign garrisons.

Only treaty ports that were opened by treaty and used are shown on the maps. Treaty ports are also not generally shown in places which are already covered by concessions or under occupation. Treaty ports are not shown after the 1911 Chinese Revolution, although they continued on into the 1940s.

Yangtze River

By the terms of the Treaty of Tientsin (1858), foreign vessels including warships had the right to free navigation on the Yangtze River. In practical terms, this right extended only as far as Yichang until 1900, when advances in steam navigation allowed access as far inland as Chongqing.
