Manchuria

Lore & Background

The name Manchuria is an exonym (derived from the endonym 'Manchu') of Japanese origin. The history of 'Manchuria' (Manzhou) as a toponym in China is disputed, with some scholars believing it was never used while others believe it was by the late 19th century. The area was historically referred to by various names in the Qing dynasty such as Guandong (East of the Pass) or the Three Provinces referring to Fengtian (Liaoning), Heilongjiang, and Jilin. Manchuria as a geographical term was first used in the 18th or 19th centuries by the Japanese before spreading to Europe. The term was promoted by the Empire of Japan in support for the existence of its puppet state, Manchukuo. Although the toponym is still used, some scholars treat the term with caution or avoid it altogether due to its association with Japanese colonialism. The term is deprecated in China due to its association with Japanese imperialism and ethnic connotations. As a result, areas once considered part of Manchuria are simply referred to as the Northeast.

Reader's Guide

Manchuria's significance lies in its role as the ancestral homeland of the Manchu people, who founded the Qing dynasty, and as a contested region between the Qing Empire, Russia, and Japan. In the 20th century, Japan used the term to justify its puppet state Manchukuo, leading to the term's controversy and deprecation in China. The region is home to diverse ethnic groups including Manchus, Mongols, Koreans, Nanai, Nivkhs, and Ulchs. Today, the area is primarily referred to as Northeast China, and its boundaries remain a subject of historical and political debate. The legacy of Manchuria includes its impact on Sino-Russian borders, Japanese imperialism, and the identity of the Manchu people.

Geography, Naming, and Modern Boundaries

Outer Manchuria—also rendered as the Great Northeast Area or Russian Manchuria—designates a swath of Northeast Asian territory that today falls within the Russian Far East but, until the mid-nineteenth century, was regarded as an integral part of the broader Manchurian region. The term "Manchuria" itself was coined during the 1800s to describe the northeastern quadrant of the Qing Empire, the ancestral homeland of the Manchu people. Once the ceded lands passed into Russian hands, the labels "Outer Manchuria" (Wài Dōngběi, literally "Outer North-East," or Wài Mǎnzhōu) and "Russian Manchuria" entered common usage to distinguish the lost territory from what remained in Chinese hands. Geographically, the area encompassed two broad zones: Priamurye, stretching from the left bank of the Amur River northward to the Stanovoy Range, and Primorskaya, covering the right banks of the Ussuri and lower Amur down to the Pacific shoreline. In modern administrative terms, this corresponds to Primorsky Krai, the southern portion of Khabarovsk Krai, the Jewish Autonomous Oblast, the Amur Oblast, and the island of Sakhalin.

Indigenous Peoples and Mixed Heritage

Before Russian annexation, the lands of Outer Manchuria were home primarily to Tungusic-speaking groups whom Han Chinese sources collectively labeled "Wild Jurchens." Among these communities, the Evenks—who speak a Tungusic language closely related to Manchu—remain a significant component of the region's indigenous population to this day. The area also saw early Korean settlement during the era of the Parhae, a Korean-Manchu polity that established communities along the Amur and in Suchan as far back as the seventh century, when Tang dynasty officials had already built administrative and military outposts in the same zone. A particularly distinctive ethnic group, the Taz people, emerged from intermarriage between Han Chinese men who migrated into the region during the Qing period and local Tungusic women. By the nineteenth century, the historian Jon K. Chang estimated roughly ten thousand Chinese and four to five thousand Koreans were present in the area, a figure that may have been an underestimate. The Qing court had, since 1644, dispatched political prisoners and criminals of various ethnicities—including Koreans—to exile in Manchuria, further diversifying the population that Russian authorities would later claim had been "deserted" after the cession.

The Unequal Treaties and Territorial Loss

Although the Qing dynasty had deliberately discouraged Han Chinese settlement in Manchuria to preserve its Manchu character, by the mid-eighteenth century the population north of the Amur and east of the Ussuri had dwindled to very few Qing subjects, leaving Russian observers to regard Chinese authority in the zone as fragile. In 1856, Russian military forces moved into the territory north of the Amur under the stated pretext of guarding it against France and the United Kingdom. Settlers established new towns, felled forests, and the Russian government organized a new maritime province, Primorskaya Oblast, whose capital was Nikolayevsk-on-Amur and whose territory stretched from Sakhalin to Kamchatka. The decisive blow came in the aftermath of the Opium Wars: weakened and compelled, the Qing court signed the Treaty of Aigun in 1858 and, following the Second Opium War, the Treaty of Peking in 1860. These agreements, part of what Chinese historians call the Unequal Treaties, redrew the Sino-Russian border along the Amur and Ussuri rivers in Russia's favor. China surrendered approximately 350,000 square miles (910,000 km²) of territory and, critically, lost its access to the Sea of Japan. In the immediate aftermath, the Qing government reversed its earlier policy and actively promoted Han Chinese migration into the remaining Manchurian lands, a movement known as Chuang Guandong.

Erasure, Revisionism, and the Fight Over Memory

In the decades following the 1860 cession, Russian and later Soviet historians engaged in a deliberate effort to erase the Chinese and Korean contributions to the Far East's development. The Russian scholar Semyon D. Anosov asserted that in the seventeenth century the Manchu-Tungus tribes of the region had been conquered and deported by China, leaving the land "deserted" ever since. A Soviet Korean historian, Kim Syn Khva, placed the first Korean migrants at just thirteen families arriving in the southern Ussuri region in 1863, fleeing poverty and famine. Yet the historian Jon K. Chang uncovered Western accounts that directly contradicted these narratives. Ernst G. Ravenstein's The Russians on the Amur and J. M. Tronson's Personal Narrative of a Voyage to Japan, Kamtschatka, Siberia, Tartary, and Various Parts of Coast of China both documented Chinese, Korean, and Manchu settlements stretching from Ternei to Vladivostok and Poset before 1863. Ravenstein, who traveled the region between 1856 and 1860, specifically noted that Koreans and Chinese prepared and sold trepangs, cultivated crops, raised cattle, and lived in small villages—evidence that the area was far from the empty wilderness that post-annexation Russian historiography preferred to describe.
