Background The
Qing dynasty was founded in the 17th century by Manchus hailing from northeastern China, conquering the ethnically Han
Shun and
Ming dynasties. Upon establishing themselves, the Qing referred to their state as in Chinese and equivalently as ; in Manchu. The name was used in official documents and treaties, and while conducting foreign affairs. The Qing equated the territory of their state, which among other regions included present-day
Manchuria,
Xinjiang,
Mongolia, and
Tibet, with the idea of 'China' itself, rejecting notions that only Han areas were core parts of China. The Qing thought of China as fundamentally multi-ethnic: the term 'Chinese people' referred to all the Han, Manchu and Mongol subjects within the empire; likewise, the term 'Chinese language' was used to refer to the
Manchu and
Mongolian languages in addition to those
language varieties that descended from Old Chinese. Moreover, the Qing stated explicitly in various edicts, as well as within the
Treaty of Nerchinsk, that the Manchu home provinces belonged to China. The Manchu homeland was referred to as the during the Qing, those provinces being
Jilin,
Heilongjiang, and
Liaoning. These regions were first delineated in 1683, but would not become actual provinces until 1907. Jilin and Heilongjiang, considered primarily Manchu, were separated from Han Liaoning along the
Willow Palisade, with internal movement and migration regulated by ethnicity. These policies continued until after the end of the
Second Opium War in the late 19th century, when the government started to encourage massive waves of Han migration to the northeast, collectively known as the
Chuang Guandong, in order to prevent the
Russian Empire from seizing more of the area. In 1907, the three provinces constituting Manchuria were officially constituted, and the
Viceroy of the Three Northeast Provinces position was established to govern them.
Qing decline and rising nationalism As the power of the court in Beijing weakened, many of the empire's outlying areas either broke free (such as
Kashgar) or fell under the control of the Western imperialist powers. The Russian Empire had set its sights on Qing's northern territories, and through
unequal treaties signed in 1858 and 1860 ultimately
annexed huge tracts of territory adjoining the
Amur River outright, now known collectively as
Outer Manchuria. As the Qing continued to weaken, Russia made further efforts to take control of the rest of Manchuria. By the 1890s, the region was under strong Russian influence, symbolized by the Russian-built
Chinese Eastern Railway that ran from
Harbin to
Vladivostok. The Japanese ultra-nationalist
Black Dragon Society initially supported
Sun Yat-sen's activities against the Qing state, hoping that an overthrow of the Qing would enable a Japanese takeover of the Manchu homeland, with the belief that Han Chinese would not oppose it.
Tōyama Mitsuru, who was the Society's leader as well as a member of the pan-Asian secret society
Gen'yōsha, additionally believed that the anti-Qing revolutionaries would even aid the Japanese in taking over, as well as helping them to enlarge the opium trade that the Qing were currently trying to destroy. The Society would support Sun and other anti-Manchu revolutionaries until the Qing ultimately collapsed. In Japan, many anti-Qing revolutionaries gathered in exile, where they founded and operated the
Tongmenghui resistance movement, whose first meeting was hosted by the Black Dragon Society. The Black Dragon Society had a large impact on Sun specifically, cultivating an intimate relationship with him. Sun often promoted pan-Asianism, and sometimes even passed himself off as Japanese. In the wake of the
1911 Revolution, the Black Dragons began infiltrating China, making inroads selling opium and spreading
anti-communist ideas. Eventually, they also began directly agitating for a Japanese takeover of Manchuria. With the
Russo-Japanese War, Japanese influence largely replaced that of Russia in Manchuria. Japan had mobilized one million soldiers to fight the Russians in Manchuria, one for every eight Japanese families. Despite shocking success, the Japanese military underwent heavy losses, ultimately incurring about 500,000 casualties. The war caused many Japanese people to develop a more possessive attitude towards Manchuria, with Japan having sacrificed so much while fighting in Manchurian territory. From 1905 on, Japanese publications often described Manchuria as a "sacred" and "holy" land where many Japanese had died as martyrs. The war had almost bankrupted Japan, forcing the Japanese to accept the compromise
Treaty of Portsmouth mediated by President
Theodore Roosevelt of the United States, under which Japan made gains, but nowhere to the extent that the Japanese public had been expecting. The Treaty of Portsmouth set off
an anti-American riot in Tokyo between 5–7 September 1905 as the general viewpoint in Japan was that the Japanese had won the war but lost the peace. The perception in Japan was the Treaty of Portsmouth was a humiliating diplomatic disaster that did not place all of Manchuria into the Japanese sphere of influence as widely expected, and the question of Manchuria was still "unfinished business" that would one day be resolved by the Imperial Army. In 1906, Japan established the
South Manchurian Railway on the southern half of the former
Chinese Eastern Railway built by Russia from
Manzhouli to
Vladivostok via
Harbin with a branch line from Harbin to
Port Arthur, now known as
Dalian. Under the terms of the Treaty of Portsmouth, the Kwantung Army had the right to occupy southern Manchuria while the region fell into the Japanese economic sphere of influence. The Japanese-owned South Manchurian Railroad company had a market capitalization of 200 million yen, making it Asia's largest corporation, which went beyond just running the former Russian railroad network in southern Manchuria to owning the ports, mines, hotels, telephone lines, and sundry other businesses, dominating the economy of Manchuria. With the growth of the South Manchuria Railroad company (
Mantetsu) came a growth in number of Japanese people living in Manchuria, from a Japanese population of 16,612 in 1906 to one of 233,749 in 1930. The majority of blue-collar employees for
Mantetsu were Chinese, and the Japanese employees were mostly white-collar, meaning most of the Japanese living in Manchuria were middle-class people who saw themselves as an elite. In Japan, Manchuria was widely seen as analogous to the Wild West: a dangerous frontier region full of bandits, revolutionaries, and warlords, but also a land of boundless wealth and promise, where it was possible for ordinary people to become very well-off. During the interwar period, Manchuria once again became a political and military battleground between Russia, Japan, and China. Imperial Japan moved into Russia's far eastern territories, taking advantage of internal chaos following the
Russian Revolution. However, in the years following the establishment of the Soviet Union, a combination of Soviet military successes and American economic pressure forced the Japanese to withdraw from the area, and Outer Manchuria would be under Soviet control by 1925.
Japanese invasion and establishment of Manchukuo During the
Warlord Era, Marshal
Zhang Zuolin established himself in Manchuria with Japanese backing. Later, the Japanese Kwantung Army found him too independent, so he was assassinated in 1928. In assassinating Marshal Zhang, the 'Old Marshal', the Kwantung Army generals expected Manchuria to descend into anarchy, providing the pretext for seizing the region. Marshal Zhang was killed when the bridge his train was riding across was blown up while three Chinese men were murdered and explosive equipment was placed on their corpses to make it appear that they were the killers, but the plot was foiled when Zhang's son
Zhang Xueliang, the 'Young Marshal', succeeded him without incident while Tokyo refused to send additional troops to Manchuria. Given that the Kwantung Army had assassinated his father, the "Young Marshal"—who unlike his father was a Chinese nationalist—had strong reasons to dislike Japan's privileged position in Manchuria. Marshal Zhang knew his forces were too weak to expel the Kwantung Army, but his relations with the Japanese were unfriendly right from the start. signed on 15 September 1932 After the
Mukden incident and
Japanese invasion of Manchuria in 1931, Japanese militarists moved forward to separate the region from Chinese control and to create a Japanese puppet state.'''''' To create an air of legitimacy, the last Emperor of China,
Puyi, was
invited to come with his followers and act as the head of state for Manchuria. One of his faithful companions was
Zheng Xiaoxu, a Qing reformist and loyalist. The "Northeast Supreme Administrative Council" was established as a Japanese puppet organization in
Manchuria following the
Mukden Incident. On 16 February 1932, the Imperial Army hosted the "Founding Conference" or "Big Four Conference" with
Liaoning governor
Zang Shiyi,
Heilongjiang governor
Zhang Jinghui, commander of the Kirin Provincial Army
Xi Qia, and general
Ma Zhanshan, in order to establish the Northeast Administrative Committee. On the committee's second meeting, the aforementioned four plus
Tang Yulin, Ling Sheng, and Qimote Semupilei were appointed as chairmen. On 18 February, the Council issued a statement announcing that "the Northeast provinces are completely independent". On 18 February 1932 Manchukuo was proclaimed by the Northeast Supreme Administrative Council nominally in control of the region. On 25 February, the Council decided that the name of the new country name (Manchukuo), the national flag, era name, and more. Manchukuo was formally established on 1 March in
Xinjing, and the council was abolished. It received formal recognition from Japan on 15 September 1932 through the
Japan–Manchukuo Protocol, after the assassination of
Japanese Prime Minister Inukai Tsuyoshi. The city of Changchun—renamed —became the capital of Manchukuo. The local Chinese organized
volunteer armies to oppose the Japanese and the new state required a
war lasting several years to
pacify the country.
Nominal transition to monarchy "Kangde") as emperor of Manchukuo Manchukuo was proclaimed a monarchy on 1 March 1934, with Puyi assuming the throne with the era name of Kangde. He was nominally assisted in his executive duties by a Privy Council and a
General Affairs State Council. This State Council was the center of political power, and consisted of several cabinet ministers, each assisted by a Japanese vice-minister. The commander-in-chief of the
Kwantung Army also served as the official Japanese ambassador to the state. He functioned in a manner similar to
resident officers in European colonial empires, with the added ability to veto decisions by the emperor. The Kwantung Army leadership placed Japanese vice ministers in his cabinet, while all Chinese advisors gradually resigned or were dismissed. , taken prior to 1945
Zheng Xiaoxu served as Manchukuo's first prime minister until 1935, when
Zhang Jinghui succeeded him. Puyi was nothing more than a figurehead and real authority rested in the hands of the Japanese military officials. An
imperial palace was specially built for the emperor. The Manchu ministers all served as frontmen for their Japanese vice-ministers, who made all decisions. In this manner, Japan formally detached Manchukuo from China over the course of the 1930s. With Japanese investment and rich natural resources, the area became an industrial powerhouse. Manchukuo had its own issued
banknotes and
postage stamps. Several independent banks were founded as well. The conquest of Manchuria proved to be extremely popular with the Japanese people who saw the conquest as providing a much-needed economic "lifeline" to their economy which had been badly hurt by the Great Depression. The very image of a "lifeline" suggested that Manchuria—which was rich in natural resources—was essential for Japan to recover from the
Great Depression, which explains why the conquest was so popular at the time and later why the Japanese people were so completely hostile towards any suggestion of letting Manchuria go. At the time, censorship in Japan was nowhere near as stringent as it would later become, and the American historian Louise Young noted: "Had they wished, it would have been possible in 1931 and 1932 for journalists and editors to express anti-war sentiments". The popularity of the conquest meant that newspapers such as the
Asahi Shimbun that had initially opposed the war swiftly pivoted to support the war as the best way of improving sales. The conquest of Manchuria was also presented as resolving the "unfinished business" left over the
Russo-Japanese war that finally undid one of the key terms of the Treaty of Portsmouth. The most popular song in Japan in 1932 was the
Manchuria March whose verses proclaimed that the seizing of Manchuria in 1931–32 was a continuation of what Japan had fought for against Russia in 1904–05, and the ghosts of the Japanese soldiers killed in the Russo-Japanese war could now rest at ease as their sacrifices had not been in vain. In 1935, Manchukuo purchased the Chinese Eastern Railway from the Soviet Union.
Second Sino-Japanese War , 1939 During the
Second Sino-Japanese War, the Japanese used Manchukuo as a base to conduct their invasion of the rest of China. The Manchu general
Tong Linge was killed in action by the Japanese in the
Battle of Beiping–Tianjin, which marked the beginning of the Second Sino-Japanese War. In the summer of 1939, a border dispute between Manchukuo and the
Mongolian People's Republic resulted in the
Battles of Khalkhin Gol. During these battles, a combined Soviet–Mongolian force defeated a
Kwantung Army with limited Manchukuoan support.
Soviet invasion, dissolution, and aftermath On 8 August 1945, the
Soviet Union declared war on Japan, in accordance with the agreement at the
Yalta Conference, and
invaded Manchukuo from Outer Manchuria and Outer Mongolia. During the Soviet offensive, the
Manchukuo Imperial Army, on paper a 200,000-man force, performed poorly and whole units surrendered to the Soviets without firing a single shot; there were even cases of armed riots and mutinies against the Japanese forces. Puyi abdicated on 17 August and had hoped to escape to Japan to surrender to the Americans, but the Soviets captured him and eventually extradited him to the government of China, when the
Chinese Communist Party (CCP) came to power in 1949, where the authorities had him imprisoned on charges of
war crimes, along with all other captured Manchukuo officials. From 1945 to 1948, Manchuria served as a base of operations for the
People's Liberation Army against the
National Revolutionary Army in the
Chinese Civil War. The CCP used Manchuria as a staging ground until the final Nationalist retreat to Taiwan in 1949. Many Manchukuo army and Japanese Kantōgun personnel served with CCP troops during the Chinese Civil War against the Nationalist forces. Most of the 1.5 million Japanese who had been left in Manchukuo at the end of World War II were sent back to their homeland in 1946–1948 by U.S. Navy ships in the operation now known as the
Japanese repatriation from Huludao. == Politics ==
