Treaty of Nanking in the context of "History of Macau"

The handover of Macau from the Portuguese Republic to the People's Republic of China (PRC) officially occurred at midnight on 20 December 1999. This event ended 442 years of Portuguese rule in the former settlement, which began in 1557. Macau was settled by Portuguese merchants that year during the Ming dynasty era and was subsequently under various degrees of Portuguese rule until 1999. Portugal's involvement in the region was formally recognised by the Qing dynasty in 1749. The Portuguese governor João Maria Ferreira do Amaral, emboldened by British actions in the First Opium War and the Treaty of Nanking, attempted to annex the territory by expelling Qing authorities in 1846, but was assassinated in 1849. After the Second Opium War, the Portuguese government, along with a British representative, signed the 1887 Sino-Portuguese Treaty of Peking that gave Portugal perpetual colonial rights to Macau on the condition that Portugal would cooperate in efforts to end the smuggling of opium.

After the Proclamation of the People's Republic of China in 1949 and the transfer of China's seat from the Republic of China (ROC) to the PRC at the United Nations (UN) in 1971, then Chinese foreign Minister Huang Hua appealed to the UN Special Committee on Decolonization to remove Macau and Hong Kong from its list of colonies, preferring to engage in direct bilateral negotiations in getting the territories returned rather than the independence of the territories as was implied by its inclusion on the list.

Hong Kong was under British rule from 1841 to 1997, except for a brief period of Japanese occupation during the Second World War from 1941 to 1945. It was a Crown colony of the United Kingdom from 1841 to 1981, and a dependent territory from 1981 to 1997. The colonial period began with the British occupation of Hong Kong Island under the Convention of Chuenpi in 1841 of the Victorian era, and ended with the handover of Hong Kong in July 1997.

In accordance with Article III of the Treaty of Nanking of 1842, signed in the aftermath of the First Opium War, the island of Hong Kong was ceded in perpetuity to Great Britain. It was established as a Crown colony in 1843. In 1860, the British expanded the colony with the addition of the Kowloon Peninsula and was further extended in 1898 when the British obtained a 99-year lease of the New Territories. Although the Qing had to cede Hong Kong Island and Kowloon in perpetuity as per the treaty, the leased New Territories comprised 86.2% of the colony and more than half of the entire colony's population. With the lease nearing its end during the late 20th century, Britain did not see any viable way to administer the colony by dividing it, whilst the People's Republic of China would not consider extending the lease or allowing continued British administration thereafter.

Hong Kong Island (simplified Chinese: 香港岛; traditional Chinese: 香港島; pinyin: xiāng gǎng dǎo; Jyutping: Hoeng1 gong2 dou2; Cantonese Yale: Hēunggóng dóu) is an island in the southern part of Hong Kong. The island, known originally and on road signs simply as "Hong Kong", had a population of 1,289,500 and a population density of 16,390 per square kilometre (42,400/sq mi), as of 2023. It is the second largest island in Hong Kong, with the largest being Lantau Island. Hong Kong Island forms one of the three areas of Hong Kong, with the other two being Kowloon and the New Territories.

In 1842, following the Qing dynasty's defeat at the First Opium War (1839–1842), Hong Kong Island was formally ceded in perpetuity to the United Kingdom under the Treaty of Nanking. The City of Victoria was then established on the island by British forces, named in honour of Queen Victoria. At that time, the island had a population of about 3,000 inhabitants scattered in a dozen fishing villages.

The First Opium War (Chinese: 第一次鴉片戰爭; pinyin: Dìyīcì yāpiàn zhànzhēng), also known as the Anglo-Chinese War, was a series of military engagements fought between the British Empire and the Chinese Qing dynasty between 1839 and 1842. The immediate issue was the Chinese enforcement of their ban on the opium trade by seizing private opium stocks from mainly British merchants at Guangzhou (then named Canton) and threatening to impose the death penalty for future offenders. Despite the opium ban, the British government supported the merchants' demand for compensation for seized goods, and insisted on the principles of free trade and equal diplomatic recognition with China. Opium was Britain's single most profitable commodity trade of the 19th century. After months of tensions between the two states, the Royal Navy launched an expedition in June 1840, which ultimately defeated the Chinese using technologically superior ships and weapons by August 1842. The British then imposed the Treaty of Nanking, which forced China to increase foreign trade, give compensation, and cede Hong Kong Island to the British. Consequently, the opium trade continued in China. Twentieth-century nationalists considered 1839 the start of a century of humiliation, and many historians consider it the beginning of modern Chinese history.

In the 18th century, the European demand for Chinese luxury goods (particularly silk, porcelain, and tea) created a trade imbalance between China and Britain. European silver flowed into China through the Canton System, which confined incoming foreign trade to the southern port city of Guangzhou. To counter this imbalance, the British East India Company began to grow opium in Bengal and allowed private British merchants to sell opium to Chinese smugglers for illegal sale in China. The influx of narcotics reversed the Chinese trade surplus and increased the numbers of opium addicts inside the country, outcomes that seriously worried Chinese officials.

Guangzhou is the capital and largest city of southern China's Guangdong province. Located on the Pearl River about 120 km (75 mi) northwest of Hong Kong and 145 km (90 mi) north of Macau, Guangzhou has a history of over 2,200 years and was a major terminus of the Silk Road.

The port of Guangzhou serves as transportation hub. Guangzhou is also one of China's three largest cities. For a long time, it was the only Chinese port accessible to most foreign traders. Guangzhou was captured by the British during the First Opium War and no longer enjoyed a monopoly after the war. Consequently it lost trade to other ports such as Hong Kong and Shanghai, but continued to serve as a major entrepôt. Following the Second Battle of Chuenpi in 1841, the Treaty of Nanking was signed between Sir Robert Peel on behalf of Queen Victoria and Lin Zexu on behalf of Emperor Xuanzong and ceded Hong Kong to the United Kingdom on 26 January 1841 after the agreement of the Convention of Chuenpi.

The Shanghai International Settlement originated from the 1863 merger of the British and American enclaves in Shanghai, in which British and American citizens would enjoy extraterritoriality and consular jurisdiction under the terms of unequal treaties agreed by both parties. These treaties were abrogated in 1943.

The British settlements were established following the victory of the British in the First Opium War (1839–1842). Under the terms of the Treaty of Nanking, the five treaty ports including Shanghai were opened to foreign merchants, overturning the monopoly then held by the southern port of Canton (Guangzhou) under the Canton System. The British also established a base on Hong Kong. American and French involvement followed closely on the heels of the British and their enclaves were established north and south, respectively, of the British area.

The Convention of Chuenpi (also "Chuenpee", pinyin: Chuān bí) was a tentative agreement between British Plenipotentiary Charles Elliot and Chinese Imperial Commissioner Qishan during the First Opium War between the United Kingdom and the Qing dynasty of China. The terms were published on 20 January 1841, but both governments rejected them and dismissed Elliot and Qishan, respectively, from their positions. Foreign Secretary Lord Palmerston stated that Elliot acquired too little while the Daoguang Emperor believed Qishan conceded too much. Palmerston appointed Major-General Henry Pottinger to replace Elliot, while the emperor appointed Yang Fang to replace Qishan, along with Yishan as General-in-Chief of Repressing Rebellion and Longwen as an assistant regional commander. Although the convention was unratified, many of the terms were later included in the Treaty of Nanking (1842).

The history of opium in China began with the use of opium for medicinal purposes during the 7th century. In the 17th century the practice of mixing opium with tobacco for smoking spread from Southeast Asia, creating a far greater demand.

Imports of opium into China were 200 chests annually in 1729, when the first anti-opium edict was promulgated. By the time Chinese authorities reissued the prohibition in starker terms in 1799, the figure had leaped; 4,500 chests were imported in the year 1800. The decade of the 1830s witnessed a rapid rise in opium trade, and by 1838, just before the First Opium War, it had climbed to 40,000 chests. The rise continued on after the Treaty of Nanking (1842) that concluded the war. By 1858 annual imports had risen to 70,000 chests (4,480 long tons (4,550 t)), approximately equivalent to one year's worth of the total global production of opium between 1995 and 2005.
