Monarchy of China

While the Chinese monarchy was originally established along the Yellow River and Yangtze River in China proper, various Chinese dynasties expanded to incorporate other regions into the Chinese realm.^{[9][10][11][12][13][14][15][16][17][18][19][20][21]}

At various points in time, the Chinese monarchy exercised control over China proper (including Hainan, Macau, and Hong Kong),^[9][10][11] Taiwan,^[12] Manchuria (both Northeast China and Outer Manchuria),^[13][14] Sakhalin,^[15][16] Mongolia (both Inner Mongolia and Outer Mongolia),^[14][17] Vietnam,^[18][22] Tibet,^[13][14] Xinjiang,^[19] as well as parts of Central Asia,^[14][15] the Korean Peninsula,^[20] Afghanistan,^[21][23] and Siberia.^[14] In particular, certain groups of Western scholars use the term "China proper" to distinguish the "core" region of China populated chiefly by the Han people from the "frontier" regions of the Chinese monarchical realm with significant populations of ethnic minorities.

The Chinese monarchy reached its largest territorial extent under either the Yuan dynasty or the Qing dynasty, depending on the historical source.^{[24][25][26][27][28]} This discrepancy can be mainly attributed to the ambiguous northern border of the Yuan dynasty: whereas some sources describe the Yuan border as located to the immediate north of the northern shore of Lake Baikal, others posit that the Yuan dynasty reached as far north as the Arctic coast.^[29][30][31] Contrastingly, the borders of the Qing dynasty were demarcated and reinforced through a series of international treaties, including the Treaty of Nerchinsk and the Treaty of Kyakhta, and thus were more well-defined. The total area under the control of the Qing dynasty amounted to more than 13 million km² at its peak.^[32][33][34]

Apart from exercising direct control over the Chinese realm, the Chinese monarchy also maintained hegemony over other states through the Chinese tributary system.^[35] The Chinese tributary system had its roots during the Western Han dynasty and lasted until the 19th century CE when the Sinocentric order collapsed.^[36][37]

Since the establishment of the Xia dynasty, China had been ruled by a succession of dynasties. A recurring theme in Chinese history, dynastic transitions occurred typically as a result of military conquest or usurpation. Historians often seek to account for Chinese dynastic transitions using the concept of dynastic cycle.^[38][39][40]

In history, China was ruled by dynasties of various ethnic origins.^[8] Although it is a common practice in Chinese historiography to label a particular dynasty as being ruled by a specific ethnicity, there were Chinese monarchs who had mixed heritage. For instance, the Emperor Xiaoming of the Xianbei-led Northern Wei dynasty was of mixed Xianbei and Han heritage; he obtained his Han ancestry from his mother, the Empress Ling.^[41] Similarly, the Kangxi Emperor of the Manchu-led Qing dynasty was of mixed Manchu and Han descent; he acquired his Han ancestry from his mother, the Empress Xiaokangzhang.^[42] Therefore, the ethnic identity of the ruling families as assigned by historians should not be regarded as absolute.

On 10 October 1911, the Wuchang Uprising broke out in modern-day Wuhan, marking the start of the Xinhai Revolution.^[43] Led by the Tongmenghui, the predecessor of the Kuomintang, the Xinhai Revolution soon spread to other parts of China. On 1 January 1912, the Republic of China was proclaimed by Sun Yat-sen in Nanjing.^[44] On 12 February 1912, the Xuantong Emperor abdicated, marking the end of the Qing dynasty and the Chinese monarchy altogether.^[43]

According to the theory of the succession of states and Chinese historiographical tradition, the Republic of China is accepted as the legitimate successor to the Qing dynasty and the Chinese monarchy. In particular, the Imperial Edict of the Abdication of the Qing Emperor issued by the Empress Dowager Longyu provided the legal basis for the Republic of China to inherit all territories of the Qing dynasty and to preserve the territorial integrity of the new Chinese state.^[45][46][47]

The National Day of the Republic of China, celebrated today in the Taiwan Area, commemorates the anniversary of the Wuchang Uprising.^[48] It was also celebrated officially in mainland China between 1912 and 1949 prior to the retreat of the Government of the Republic of China to Taiwan.

During and after the Xinhai Revolution, there were various attempts at reviving the Chinese monarchy. All these attempts ultimately ended in failure.

Emperorship by Duke of Yansheng or Marquis of Extended Grace

During the Xinhai Revolution, there were numerous proposals advocating for the replacement of the Manchu-led Qing dynasty by a new dynasty of Han ethnicity. Kong Lingyi (孔令貽), a 76th-generation descendant of Confucius and the Duke of Yansheng, was identified as a potential candidate for Chinese emperorship by Liang Qichao.^[49] Meanwhile, gentry in Anhui and Hebei supported a restoration of the Ming dynasty under Zhu Yuxun (朱煜勳), the Marquis of Extended Grace.^[50] Both suggestions failed to materialize. In the year of 1937, the Japanese during their conquest of China offered the position of "Emperor of China" to the Duke of Yansheng, Kung Te-cheng, but he declined the offer.

Empire of China

In 1915, Yuan Shikai proclaimed the Empire of China.^[51] It soon sparked the National Protection War and the empire was abolished after 3 months.

Manchu Restoration

In 1917, the Qing loyalist Zhang Xun reinstalled Puyi to the Chinese throne.^[52] This attempt at restoring the Qing dynasty, known as the Manchu Restoration, lasted only 11 days.

Manchukuo

The Japanese puppet state Manchukuo was established in Northeast China in 1932.^[53] This regime subsequently became a monarchy with Puyi as the emperor in 1934. Manchukuo collapsed in 1945 following the Soviet invasion of Manchuria and the unconditional surrender of Japan.
