The 'Liaodong Peninsula' (
sim. ch. 辽东半岛) is a
peninsula in the
Liaoning province of northeastern
China, historically known in the west as southern east-
Manchuria. ''Liaodong'' (formerly spelled ''Liaotung'') means "East of the Liao". The
Liao River was a river during the
Warring States that divided the Yan commandries of Liaoxi (Simplified Chinese: 辽西)(west of the Liao) and Liaodong.
Geography
The peninsula is situated at the north of the
Yellow Sea, between the
Bohai Sea to the west and the
Korea Bay to the east.
It forms the southern part of a mountain belt that continues northward in the
Changbai Mountains. The part of the mountain range on the peninsula is known as the
Qian Mountains.
The two
seaports,
Dalian (''Dairen'' in Japanese) which lies midway along the peninsula at its narrowest point and Port Arthur/Lushun (now a consolidation of several municipalities known as Lüshun City), which is located at its southernmost point. Lüshun City is the governmental district seat of the southernmost "Dalian districts" (county-level government), known as
Lüshunkou (literally "Lüshun Port"), organized under the
sub-provincial city of Dalian. Lüshun/Port Arthur has a large lake-like naturally-protected harbor and semi-sheltered outer roadstead making it very attractive to imperialist
powers at the end of the
nineteenth century. Dalny/Dairen/Dalian's harbor required greater investment, initially supplied by the Russians, but turned into a first class city under the Japanese period of administration (1905–1945). The two ports are about 25 miles apart by rail, but about 40 nautical miles apart by sea. Lüshun is 550 rail miles south of the Manchurian railroad hub city of
Harbin on the historic Southern Manchurian Railway (today's
China Far East Railway (CER), which construction was one of the underlying
casus belli of the
Russo-Japanese War).
History
The island was an important area of conflict during the
First Sino-Japanese War (1894–1895), which the Japanese won. Defeat precipitated decline in the Chinese Empire which was exploited by
colonial powers who extracted numerous concessions. The peninsula was
ceded to Japan by the
Treaty of Shimonoseki of
April 17,
1895 but this was rescinded after the
Triple Intervention of
April 23,
1895 by Russia, France and Germany. In the aftermath of this intervention, the Russian government pressured the ruling
Qing dynasty to lease Liaodong and the strategically important Lüshunkou (Port Arthur) for use by the Russian Navy. This caused resentment in Japan and was a factor leading to the
Russo-Japanese War (
1904–
1905) when negotiations concerning the peninsula,
Manchuria, and
Korea broke down, due to Russia's unwillingness to treat seriously with Japan as another power. As in the First Sino-Japanese War the Liaodong peninsula was the scene of major fighting in the Russo-Japanese War. As a consequence of the
Treaty of Portsmouth (
September 5,
1905), which ended the Russo-Japanese War, both sides agreed to evacuate Manchuria and return its sovereignty to China, but Japan was given the lease for the Liaotung/Liaodong.
