Manchu people in the context of "Eight Banners"

Manchuria is a region in East Asia. Depending on the definition of its extent, Manchuria can refer either to a region falling entirely within present-day China, or to a larger region today divided between Northeast China and the Russian Far East. To differentiate between the two parts following the latter definition, the Russian part is also known as Outer Manchuria (or Russian Manchuria), while the Chinese part is known as Northeast China.

Manchuria is the homeland of the Manchu people. "Manchu" is a name introduced by Hong Taiji of the Qing dynasty in 1636 for the Jurchen people, a Tungusic people.

The island of Taiwan, also commonly known as Formosa, was partly under colonial rule by the Dutch Republic from 1624 to 1662 and from 1664 to 1668. In the context of the Age of Discovery, the Dutch East India Company established its presence on Formosa to trade with neighboring Ming China and Tokugawa Japan, and to interdict Portuguese and Spanish trade and colonial activities in East Asia.

The Dutch were not universally welcomed, and uprisings by both aborigines and recent Han arrivals were quelled by the Dutch military on more than one occasion. With the rise of the Manchu-led Qing dynasty in the early 17th century, the Dutch East India Company cut ties with Ming China and allied with the Manchu Qing instead, in exchange for the right to unfettered access to their trade and shipping routes. The colonial period was brought to an end after the 1662 siege of Fort Zeelandia by Koxinga's army who promptly dismantled the Dutch colony, expelled the Dutch and established the Ming loyalist, anti-Qing Kingdom of Tungning.

The Republic of China (ROC) was established on 1 January 1912 as a sovereign state in mainland China following the 1911 Revolution, which overthrew the Manchu-led Qing dynasty and ended China's imperial history. From 1927, the Kuomintang (KMT) reunified the country and initially ruled it as a one-party state with Nanjing as the national capital. In 1949, the KMT-led government was defeated in the Chinese Civil War and lost control of the mainland to the Chinese Communist Party (CCP). The CCP established the People's Republic of China (PRC) while the ROC was forced to retreat to Taiwan; the ROC retains control over the Taiwan Area, and its political status remains disputed. The ROC is recorded as a founding member of both the League of Nations and the United Nations, and previously held a permanent seat on the United Nations Security Council until 1971, when the PRC took the seat of China from the ROC in the United Nations General Assembly Resolution 2758. It was also a member of the Universal Postal Union and the International Olympic Committee. The ROC claimed 11.4 million km (4.4 million sq mi) of territory, and its population of 541 million in 1949 made it the most populous country in the world.

The Republic of China was officially proclaimed on 1 January 1912 by revolutionaries under Sun Yat-sen, the ROC's founder and provisional president of the new republic, following the success of the 1911 Revolution. Puyi, the final Qing emperor, abdicated on 12 February 1912. Sun served briefly before handing the presidency to Yuan Shikai, the leader of the Beiyang Army. Yuan's Beiyang government quickly became authoritarian and exerted military power over the administration; in 1915, Yuan attempted to replace the Republic with his own imperial dynasty until popular unrest forced him to back down. When Yuan died in 1916, the country fragmented between local commanders of the Beiyang Army, beginning the Warlord Era defined by decentralized conflicts between rival cliques. At times, the most powerful of these cliques used their control of Beijing to assert claims to govern the entire Republic.

Jurchen (Manchu: ᠵᡠᡧᡝᠨ, romanized: Jušen, [dʒuʃən]; Chinese: 女真, romanized: Nǚzhēn, [nỳ.ʈʂə́n]) were a number of East Asian Tungusic-speaking people. They lived in northeastern China, also known as Manchuria, before the 18th century. The Jurchens were renamed Manchus in 1635 by Hong Taiji. The Jurchens were culturally diverse, with different groups living as hunter-gatherers, pastoralist semi-nomads, or sedentary agriculturists. Generally lacking a central authority, and having little communication with each other, many Jurchen groups fell under the influence of neighbouring dynasties, their chiefs paying tribute and holding nominal posts as effectively hereditary commanders of border guards.

Han officials of the Ming dynasty (1368–1644) classified them into three groups, reflecting relative proximity to the Ming:

Manchu (ᠮᠠᠨᠵᡠ
ᡤᡳᠰᡠᠨ Manju gisun) is a critically endangered Tungusic language native to the historical region of Manchuria in Northeast China. As the traditional native language of the Manchus, it was the national language of the Qing dynasty (1644–1912) of China, although today the vast majority of Manchus speak only Mandarin Chinese. Several thousand can speak Manchu as a second language through governmental primary education or free classes for adults in classrooms or online. There are no more native speakers of Manchu as of 2024.

The Manchu language has high historical value for historians of China, especially for the Qing dynasty. Manchu-language texts supply information that is unavailable in Chinese, and when both Manchu and Chinese versions of a given text exist, they provide controls for understanding the Chinese.

Manchuria is a historical region in northeast Asia encompassing the entirety of present-day northeast China and parts of the modern-day Russian Far East south of the Uda River and the Tukuringra-Dzhagdy Ranges. The exact geographical extent varies depending on the definition: in the narrow sense, the area constituted by three Chinese provinces of Heilongjiang, Jilin, and Liaoning as well as the eastern Inner Mongolian prefectures of Hulunbuir, Hinggan, Tongliao, and Chifeng; in a broader sense, historical Manchuria includes those regions plus the Amur river basin, parts of which were ceded to the Russian Empire by the Manchu-led Qing dynasty during the Amur Annexation of 1858–1860. The parts of Manchuria ceded to Russia are collectively known as Outer Manchuria or Russian Manchuria, which include present-day Amur Oblast, Primorsky Krai, the Jewish Autonomous Oblast, the southern part of Khabarovsk Krai, and the eastern edge of Zabaykalsky Krai.

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. The Three Provinces and the Northeast were also in concurrent use among the Japanese along with Manchuria until the Mukden incident of 1931.

Manchukuo, officially known as the State of Manchuria prior to 1934 and the Empire of Great Manchuria thereafter, was a puppet state of the Empire of Japan in Northeast China that existed from 1932 until its dissolution in 1945. It was ostensibly founded as a republic, its territory consisting of the lands seized in the Japanese invasion of Manchuria; it was later declared to be a constitutional monarchy in 1934, though very little changed in the actual functioning of government. Manchukuo received limited diplomatic recognition, primarily from states aligned with the Axis powers, with its existence widely regarded as illegitimate.

The region now known as Manchuria had historically been the homeland of the Manchu people, though by the 20th century they had long since become a minority in the region, with Han Chinese constituting by far the largest ethnic group. The Manchu-led Qing dynasty, which had governed China since 17th century, was overthrown with the permanent abolition of the dynastic system in the 1911 Xinhai Revolution, with Puyi, the final emperor of China, forced to abdicate at the age of six. In 1931, Manchuria was invaded and occupied by the Empire of Japan following the Mukden incident. A puppet government was set up the following year, with Puyi brought in by the Japanese to serve as its nominal regent, though he himself had no actual political power. Japanese officials ultimately made all pertinent decisions, and exercised total control over Puyi's court and personal safety. Upon the nominal transition from republic to empire, Puyi was proclaimed as the emperor of Manchukuo.

As a Manchu-led imperial dynasty of China and an early modern empire in East Asia, the legacy of the Qing dynasty has been significant and enduring. As the last imperial dynasty in Chinese history, it is generally agreed that the Qing dynasty had major impact in China, laying the foundation for the modern Chinese state as a geographic and ethnic entity. Additionally, it had varying degrees of influence in surrounding countries (such as Russia and Mongolia) and other parts of the world.

Nurhaci (14 May 1559 – 30 September 1626), also known by his temple name as the Emperor Taizu of Qing, was the founding khan of the Jurchen-led Later Jin dynasty.

As leader of the Aisin-Gioro clan, Nurhaci reorganized and united various Jurchen tribes (the later "Manchu"), consolidated the Eight Banners military system, and eventually launched attacks on both the Ming and Joseon dynasties. His conquest of Ming dynasty's northeastern Liaodong region laid the groundwork for the Qing conquest of the Ming by his descendants, who proclaimed the Qing dynasty in 1636. He is also generally credited with ordering the creation of a new written script for the Manchu language based on the Mongolian vertical script.
