Qing Empire in the context of "Hong Kong units of measurement"

In the field of international relations, a sphere of influence (SOI) is a spatial region or concept division over which a state or organization has a level of cultural, economic, military, or political exclusivity.

While there may be a formal alliance or other treaty obligations between the influenced and influencer, such formal arrangements are not necessary and the influence can often be more of an example of soft power. Similarly, a formal alliance does not necessarily mean that one country lies within another's sphere of influence. High levels of exclusivity have historically been associated with higher levels of conflict.

The century of humiliation (simplified Chinese: 百年国耻; traditional Chinese: 百年國恥; pinyin: bǎinián guóchǐ) was a period in Chinese history beginning with the First Opium War (1839–1842), and ending in 1945 with China (then the Republic of China) emerging out of the Second World War as one of the Big Four and established as a permanent member of the United Nations Security Council, or alternatively, ending in 1949 with the founding of the People's Republic of China. The century-long period is typified by the decline, defeat and political fragmentation of the Qing dynasty and the subsequent Republic of China, which led to demoralizing foreign intervention, annexation and subjugation of China by Western powers, Russia, and Japan.

The characterization of the period as a "humiliation" arose with an atmosphere of Chinese nationalism following China's defeat in the First Sino-Japanese War of 1894–1895 and the subsequent events including the scramble for concessions in the late 1890s. Since then the idea of national humiliation became a focus of discussions among many Chinese writers and scholars, although they differed somewhat in their understandings of national humiliation; ordinary scholars and constitutionalists also had different understanding of their home country from the anti-Qing revolutionaries in the late Qing period. The idea of national humiliation was also mentioned in late Qing textbooks.

The Treaty of Tientsin, also known as the Treaty of Tianjin, is a collective name for several unequal treaties signed at Tianjin (then romanized as Tientsin) in June 1858. The Qing dynasty, Russian Empire, Second French Empire, United Kingdom, and the United States were the parties involved. These treaties, counted by the Chinese among the unequal treaties, opened more Chinese ports to foreign trade, permitted foreign legations in the Chinese capital Beijing, allowed Christian missionary activity, and effectively legalized the import of opium. They ended the first phase of the Second Opium War, which had begun in 1856 and were ratified by the Emperor of China in the Convention of Peking in 1860, after the end of the war.

Ten Thousand Nations Coming to Pay Tribute (Chinese: 萬國來朝圖; pinyin: Wànguó láicháo tú, 1761) is a monumental (299x207cm) Qing dynasty painting depicting foreign delegations visiting the Qianlong Emperor in the Forbidden city in Beijing during the late 1750s.

The painting was intended to show the cosmopolitanism and the centrality of the Qing Empire, since most countries of Asia and Europe are shown paying their respects to the Chinese Emperor. China already had a long tradition of such paintings (designated as "Portraits of Periodical Offering"), starting from around the 6th century CE, but such paintings ended around the time of the Opium War, which shattered the ideal of the Great Chinese Empire in the middle of the world, and gave way to the awareness of China as simply one country among others. The principle was one of more-or-less voluntary submission, with presents being periodically brought to the Chinese Emperor as a symbolic gesture of acknowledgement of Chinese overlordship. According to Ming period writings "The Emperor resides in the center and holds the reins of all other nations and all things under the sun".

The Treaty of Kyakhta (or Kiakhta), along with the Treaty of Nerchinsk (1689), regulated the relations between Imperial Russia and the Qing Empire of China until the mid-19th century. It was signed by Tulišen and Count Sava Lukich Raguzinskii-Vladislavich at the border city of Kyakhta on 23 August 1727.

Hong Kong (1800s–1930s) oversaw the founding of the new crown colony of Hong Kong under the British Empire. After the First Opium War, the territory was ceded by the Qing Empire to the United Kingdom of Great Britain and Ireland through Treaty of Nanjing (1842) and Convention of Peking (1860) in perpetuity. Together with additional land that was leased to the British under the Convention for the Extension of Hong Kong Territory (1898), Hong Kong became one of the first parts of East Asia to undergo industrialisation.

Amursana (Mongolian ᠠᠮᠤᠷᠰᠠᠨᠠᠭ᠎ᠠ; Chinese: 阿睦爾撒納; 1723 – 21 September 1757) was an 18th-century taishi (太师; 太師) or prince of the Khoit-Oirat tribe that ruled over parts of Dzungaria and Altishahr in present-day northwest China. Known as the last great Oirat hero, Amursana was the last of the Dzungar rulers. The defeat of his rebel forces by Qing dynasty Chinese armies in the late 1750s signaled the final extinction of Mongol influence and power in Inner Asia, ensured the incorporation of Mongol territory into the Qing Chinese Empire, and brought about the Dzungar genocide, the Qing Emperor's "final solution" to China's northwest frontier problems.
