Lüshunkou District (also Lyushunkou District; 旅顺口区), commonly known as Lüshun (旅顺), is a district of Dalian, Liaoning province, China. The district has an area of 512.15 km2 (197.74 sq mi) and a permanent population of 398,579 as of 2020.
Lüshunkou is located at the extreme southern tip of the Liaodong Peninsula. It has a natural harbor, the possession and control of which became a casus belli of the Russo-Japanese War (1904–05). Japanese and then Russian administration was established in 1895 and continued until 1905 when control was ceded to Japan. During that period, it was world-famous and was more significant than the other port on the peninsula, Dalian proper.
Lüshunkou was formerly known as both Port Arthur (Russian: Порт-Артур, romanized: Port-Artur) and Ryojun (Japanese: 旅順). After World War II, it was returned to China as Lüshun City. In 1960, Lüshun was redesignated as a district of Dalian (known as Lüda until 1981).
Lüshunkou, meaning "port of smooth journeys", was named in 1371 to commemorate a successful Ming expedition into Liaodong. A naval force set sail from Penglai, Shandong and landed at Lüshunkou to attack the remaining Yuan forces on the Liaodong Peninsula.
In English-language diplomatic, news, and historical writings, it was known as Port Arthur after a British Royal Navy Lieutenant named William Arthur who surveyed the harbour in the gunboat HMS Algerine in 1860.
During the period when the Japanese Empire controlled and administered the Liaodong (= Liaotung) Peninsula it was called Ryojun (旅順), the Japanese pronunciation of the Chinese characters in the city's name. After the Japanese defeat in World War II, the city was under the administration of the Soviet Union, which rented the port from China, until 1950. Although the Soviets presented the port to the new People's Republic of China in 1950, Soviet Armed Forces troops remained in the city until 1955.
Central Dalian is some 40 km (25 mi) farther up the coast, sprawling around the narrowest neck of the Liaodong Peninsula (simplified Chinese: 辽东半岛; traditional Chinese: 遼東半島; pinyin: Liáodōng Bàndǎo), whereas Lüshun occupies its southern tip. Lüshun City surrounds the lake-like structure near the peninsular tip. The lake-like feature is the inner natural harbour of the port, a well-sheltered and fortifiable harbour to 19th century eyes.
The Liaodong Peninsula has the Yellow Sea to its southeast with Korea beyond, the Korea Bay to its due east, and the Bohai Sea (or Gulf) to its west. Beijing is due west-northwest across the Bo Hai Gulf from the port city.
In the late 1880s, the German company Krupp was contracted by the Qing dynasty to build a series of fortifications around Port Arthur. Reportedly, this was after local contractors had "made an extensive bungle of the job".
Port Arthur first came into international prominence during the First Sino-Japanese War (1894–1895). Following Japan's victory over the Imperial Chinese Army troops at the Battle of Pyongyang in Korea in September 1894, the Japanese First and Second Armies converged on the Liaodong Peninsula by land and sea. Imperial Japanese Armed Forces war planners, ambitious for control of the Liaodong Peninsula and Port Arthur and also cognizant of that port's strategic position controlling the northern Yellow Sea routes and the passage to Tianjin, were determined to seize it.
On 20–21 November 1894, 15,000 Japanese troops defeated 13,000 Qing soldiers and conquered Lüshunkou. The Port Arthur massacre resulted in the deaths of somewhere between 2,600 civilians and 20,000 people including Chinese soldiers.
Japan went on to occupy Port Arthur and to seize control of the whole Liaodong Peninsula. As part of the terms of the 1895 Treaty of Shimonoseki concluding the war, Japan was granted the Liaodong Peninsula but had to cede the territory when threatened jointly with war by France, Germany and Russia in what is called the Triple Intervention of 1895. This was seen as a great humiliation in Japan.
The Russian Empire in 1898 coerced a lease from China of the Liaodong Peninsula and created the territory of Russian Dalian. It gained railroad right-of-way to join the Liaodong Peninsula to the Chinese Eastern Railway with a line running from Port Arthur to the Chinese city of Harbin, and systematically began to fortify the town and harbour at Port Arthur. Tsar Nicholas II believed this acquisition of a Pacific port would enhance Russian security, and extend its economic influence. He was also falsely informed that the British Empire was considering seizing the port. Nicholas founded Dalny (later Dairen, now Dalian) near Port Arthur and also on the Chinese Eastern Railway. In 1902, the Russian viceroy de-emphasized Dalny, building a palace and cultural edifices at Port Arthur instead. All of these developments contributed to Japanese resentment towards Russia over competing imperial aims in Manchuria.
Russo-Japanese War (1904–1905)
Ten years later, Port Arthur again played a central role in war in China. After the Boxer Rebellion (1900–01) had been extinguished by an international Eight-Nation Alliance of troops, the Imperial Russian Army refused to withdraw its reinforcements from Manchuria and instead began to fortify and garrison the entire route along the Southern Manchurian Railway. With this development, Japan proposed the two powers meet and discuss their respective roles in eastern Manchuria, as the area was considered being in their respective spheres of influence. Talks were conducted between 1902 and 1904. While numerous proposals and agreement papers were generated between the two powers, Russia continued the de facto annexation of territory through fortification and garrison, if not de jure; while employing stalling tactics in its negotiations. In the end, after more than two years of intensive bilateral negotiations failed to clarify each country's rights, prerogatives, and interests in Manchuria, Japan attacked Port Arthur and the Russian fleet without declaring war in February 1904.
The Battle of Port Arthur, the opening battle of the Russo-Japanese War, was fought in the heavily fortified harbour of the town of Port Arthur/Lüshun on 9 February 1904 when the Japanese attacked at night with torpedoes, followed by a brief daylight skirmish by major surface combatants.
By the end of July 1904, the Japanese army had pushed down the Liaodong peninsula and was at the outer defences of Port Arthur. The fact that Japanese forces had closed to within artillery range of the harbour in early August 1904 led directly to the naval Battle of the Yellow Sea which solidified Japan's command of the sea, where her fleets continued to blockade the harbour. Virtually all the battles of the war until July 1904 were strategic battles for territorial gain or position leading to the investment and siege of the port city.
The port eventually fell 2 January 1905 after a long train of battles on land and sea during which the Japanese occupied the whole of the Korean Peninsula, split the Russian Army, devastated the Imperial Russian Navy, and cut off the source of supplies on the railway from Harbin, culminating in the bloody battle known as the Siege of Port Arthur (June–January; some sources place the siege start in late July, a technical difference due to definitions).
