Qing dynasty in Inner Asia: The Qing dynasty in Inner Asia was the expansion of the Qing dynasty's realm in Inner Asia in the 17th and the 18th century AD, including both Inner and Outer Mongolia, Manchuria, Tibet, Qinghai and Xinjiang.  Wars were fought primarily against the Northern Yuan dynasty (before 1636) and the Dzungar Khanate (1687–1758).  Even before the conquest of China proper (see Qing conquest of the Ming), the Manchus had controlled Manchuria (modern Northeast China as well as Outer Manchuria) and Inner Mongolia, with the latter being previously controlled by the Mongols under Ligdan Khan.  After suppressing the Revolt of the Three Feudatories and the conquest of Taiwan as well as ending the Sino-Russian border conflicts in the 1680s, the Dzungar–Qing War broken out.  This eventually led to Qing conquests of Outer Mongolia, Tibet, Qinghai and Xinjiang.  All of them became part of the Qing Empire and were garrisoned by Qing forces, but they were governed through several different types of administrative structure and also retained many of their existing institutions.  Furthermore, they were not governed as regular provinces (until Xinjiang and Manchuria were turned into provinces in late Qing), but instead were supervised by the Lifan Yuan, a Qing government agency that oversaw the empire's frontier regions.

Criticism of monarchy: Criticism of monarchy can be targeted against the general form of government—monarchy—or more specifically, to particular monarchical governments as controlled by hereditary royal families.  In some cases, this criticism can be curtailed by legal restrictions and be considered criminal speech, as in lèse-majesté.  Monarchies in Europe and their underlying concepts, such as the Divine Right of Kings, were often criticized during the Age of Enlightenment, which notably paved the way to the French Revolution and the proclamation of the abolition of the monarchy in France.  Earlier, the American Revolution had seen the Patriots suppress the Loyalists and expel all royal officials.  The twentieth century, beginning with the 1917 February Revolution in Russia and accelerated by two world wars, saw many European countries replace their monarchies by republics, while others replaced their absolute monarchy with constitutional monarchy.  Reverse movements also occurred, with brief returns of the monarchy in France under the Bourbon Restoration, the July Monarchy, and the Second French Empire, or with the return of the monarchy—this time as a constitutional monarchy—in Spain after the dictatorship of Francisco Franco.

Manchukuo: Manchukuo (: "Mǎnzhōuguó"literally: " State of Manchuria" ) was a puppet state in Northeast China and Inner Mongolia, which was governed under a form of constitutional monarchy.

In 1931, the region was seized by Japan following the Mukden Incident and a pro-Japanese government was installed one year later with Puyi, the last Qing emperor, as the nominal regent and emperor.  Manchukuo's government was abolished in 1945 after the defeat of Imperial Japan at the end of World War II.  The territories formally claimed by the puppet state were first seized in the Soviet invasion of Manchuria in August 1945, and then formally transferred to Chinese administration in the following year.
