Xinhai Revolution in the context of "Puyi"

The Qing dynasty (/tʃɪŋ/ CHING), officially the Great Qing, was a Manchu-led imperial dynasty of China and an early modern empire in East Asia. The last imperial dynasty in Chinese history, the Qing dynasty was preceded by the Ming dynasty and succeeded by the Republic of China. At its height of power, the empire stretched from the Sea of Japan in the east to the Pamir Mountains in the west, and from the Mongolian Plateau in the north to the South China Sea in the south. Originally emerging from the Later Jin dynasty founded in 1616 and proclaimed in Shenyang in 1636, the dynasty seized control of the Ming capital Beijing and North China in 1644, traditionally considered the start of the dynasty's rule. The dynasty lasted until the Xinhai Revolution of October 1911 led to the abdication of the last emperor in February 1912. The multi-ethnic Qing dynasty assembled the territorial base for modern China. The Qing controlled the most territory of any dynasty in Chinese history, and in 1790 represented the fourth-largest empire in world history to that point. With over 426 million citizens in 1907, it was the most populous country at the time.

Nurhaci, leader of the Jianzhou Jurchens and House of Aisin-Gioro who was also a vassal of the Ming dynasty, unified Jurchen clans (known later as Manchus) and founded the Later Jin dynasty in 1616, renouncing the Ming overlordship. As the founding Khan of the Manchu state he established the Eight Banners military system, and his son Hong Taiji was declared Emperor of the Great Qing in 1636. As Ming control disintegrated, peasant rebels captured Beijing as the short-lived Shun dynasty, but the Ming general Wu Sangui opened the Shanhai Pass to the Qing army, which defeated the rebels, seized the capital, and took over the government in 1644 under the Shunzhi Emperor and his prince regent. While the Qing became a Chinese empire, resistance from Ming rump regimes and the Revolt of the Three Feudatories delayed the complete conquest until 1683, which marked the beginning of the High Qing era. As an emperor of Manchu ethnic origin, the Kangxi Emperor (1661–1722) consolidated control, relished the role of a Confucian ruler, patronised Buddhism, encouraged scholarship, population and economic growth.

The Qin dynasty (/tʃɪn/ CHIN) was the first imperial dynasty of China. It is named for its progenitor state of Qin, a fief of the confederal Zhou dynasty (c. 1046–256 BC). Beginning in 230 BC, the Qin under King Ying Zheng engaged in a series of wars conquering each of the rival states that had previously pledged fealty to the Zhou. This culminated in 221 BC with the successful unification of China under Qin, which then assumed an imperial prerogative – with Ying Zheng declaring himself to be Qin Shi Huang, the first emperor of China, and bringing an end to the Warring States period (c. 475–221 BC). This state of affairs lasted until 206 BC, when the dynasty collapsed in the years following Qin Shi Huang's death. The Qin dynasty's 14-year existence was the shortest of any major dynasty in Chinese history, with only two emperors. However, the succeeding Han dynasty (202 BC – 220 AD) largely continued the military and administrative practices instituted by the Qin; as a result, the Qin have been credited as the originators of the Chinese imperial system that would endure in some form until the Xinhai Revolution in 1911.

Qin was a minor power for the first several centuries of its existence; its strength greatly increased in the 4th century BC, in large part owing to the administrative and military reforms of Shang Yang. They sought to create a strong, centralised state and a large army supported by a stable economy, which were developed in the Qin homeland and implemented across China following its unification. Reforms included the standardisation of currency, weights, measures, and the writing system, along with innovations in weaponry, transportation and military tactics.

The Warlord Era was the period in the history of the Republic of China between 1916 and 1928, when control of the country was divided between rival military cliques of the Beiyang Army and other regional factions. It began after the death of Yuan Shikai, the President of China after the Xinhai Revolution had overthrown the Qing dynasty and established the Republic of China in 1912. Yuan's death on 6 June 1916 created a power vacuum which was filled by military strongmen and widespread violence, chaos, and oppression. The Nationalist Kuomintang (KMT) government of Sun Yat-sen, based in Guangzhou, began to contest Yuan's Beiyang government based in Beijing for recognition as the legitimate government of China.

The most powerful cliques were the Zhili clique led by Feng Guozhang, who controlled several northern provinces; the Anhui clique led by Duan Qirui, based in several southeastern provinces; and the Fengtian clique led by Zhang Zuolin, based in Manchuria. The three cliques often engaged in conflict for territory and hegemony. In mid-1917, after Yuan's successor Li Yuanhong attempted to remove Duan as premier, the general Zhang Xun forced Li to resign and made a brief attempt to restore the Qing dynasty, which was quashed by Duan's troops. Feng became the acting president, but was forced to step down by Duan in late 1918 and was replaced by Xu Shichang. In mid-1920, the new Zhili clique leaders, Cao Kun and Wu Peifu, defeated Duan in the Zhili–Anhui War in an alliance with Zhang Zuolin. A power struggle broke out between Cao and Zhang which ended with Cao's victory in the First Zhili–Fengtian War in 1922. Cao was president until 1924, when during the Second Zhili–Fengtian War he was betrayed by his subordinate Feng Yuxiang, who joined with Zhang to stage a coup against Cao. Feng and Zhang shared power and recalled Duan to serve as president before Zhang removed them both in 1926; in 1927, he declared himself Generalissimo.

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.

The Wuchang Uprising was an armed rebellion against the ruling Qing dynasty that took place in Wuchang (now Wuchang District of Wuhan) in the Chinese province of Hubei on 10 October 1911, beginning the Xinhai Revolution that successfully overthrew China's last imperial dynasty. It was led by elements of the New Army, influenced by revolutionary ideas from Tongmenghui. The uprising and the eventual revolution led to the downfall of the Qing dynasty after almost three centuries of imperial rule, and the establishment of the Republic of China (ROC). Taiwan commemorates the anniversary of the uprising's outbreak on 10 October as the National Day of the Republic of China.

The uprising originated from popular unrest about a railway crisis, and the planning process took advantage of the situation. On 10 October 1911, the New Army stationed in Wuchang launched an assault on the residence of the Viceroy of Huguang. The viceroy Ruicheng quickly fled from the residence, and the revolutionaries soon took control of the entire city.

The Reorganized National Government of the Republic of China, commonly described as the Wang Jingwei regime, was a puppet state of the Empire of Japan in eastern China. It existed coterminous with the Nationalist government of the Republic of China under Chiang Kai-shek, which was fighting Japan alongside the other Allies of World War II. The country functioned as a dictatorship under Wang Jingwei, formerly a high-ranking official of the Kuomintang (KMT) party. The region it administered was initially seized by Japan during the late 1930s at the beginning of the Second Sino-Japanese War.

Wang, a rival of Chiang Kai-shek and member of the pro-peace faction of the KMT, defected to the Japanese side and formed a collaborationist government in occupied Nanjing in 1940, as well as a concurrent collaborationist Kuomintang that ruled the new government. The new state claimed the entirety of China (outside the Japanese puppet state of Manchukuo) during its existence, portraying itself as the legitimate inheritors of the Xinhai Revolution and Sun Yat-sen's legacy as opposed to Chiang's government in Chongqing, but effectively only Japanese-occupied territory was under its direct control. Its international recognition was limited to other members of the Anti-Comintern Pact, of which it was a signatory. The Reorganized National Government existed until the end of World War II and the surrender of Japan in August 1945, at which point the regime was dissolved and many of its leading members were executed for treason.
