First Opium War

The First Opium War (1839–42), also known as the Opium War and as the Anglo-Chinese War, was fought between the United Kingdom of Great Britain and Ireland and the Qing Empire over their conflicting viewpoints on diplomatic relations, trade, and the administration of justice for foreign nationals.

In the 17th and 18th centuries, the demand for Chinese goods (particularly silk, porcelain, and tea) in the European market created a trade imbalance because the market for Western goods in China was virtually non-existent; China was largely self-sufficient and Europeans were not allowed access to China's interior. European silver flowed into China when the Canton System, instituted in the mid-17th century, confined the sea trade to Canton and to the Chinese merchants of the Thirteen Factories. The British East India Company had a matching monopoly of British trade. The British East India Company began to auction opium grown on its plantations in India to independent foreign traders in exchange for silver. The opium was then transported to the Chinese coast and sold to local middlemen who retailed the drug inside China. This reverse flow of silver and the increasing numbers of opium addicts alarmed Chinese officials.

Hong Kong

Hong Kong (香港; "Fragrant Harbour"), officially Hong Kong Special Administrative Region of the People's Republic of China, is an autonomous territory on the southern coast of China at the Pearl River Estuary and the South China Sea. Hong Kong is known for its skyline and deep natural harbour. It has a land area of 1104 km² and shares its northern border with Guangdong Province of Mainland China. With around 7.2 million inhabitants of various nationalities, Hong Kong is one of the world's most densely populated metropolises.

After the First Opium War (1839–42), Hong Kong became a British colony with the perpetual cession of Hong Kong Island, followed by Kowloon Peninsula in 1860 and a 99-year lease of the New Territories from 1898. Hong Kong remained under British control for about a century until the Second World War, when Japan occupied the colony from December 1941 to August 1945. After the Surrender of Japan, the British resumed control. In the 1980s, negotiations between the United Kingdom and the China resulted in the 1984 Sino-British Joint Declaration, which provided for the transfer of sovereignty of Hong Kong on 30 June 1997. The territory became a special administrative region of China with a high degree of autonomy on 1 July 1997 under the principle of one country, two systems. Disputes over the perceived misapplication of this principle have contributed to popular protests, including the 2014 Umbrella Revolution.

China

China, officially the People's Republic of China (PRC), is a sovereign state in East Asia. It is the world's most populous country, with a population of over 1.35 billion. The PRC is a one-party state governed by the Communist Party, with its seat of government in the capital city of Beijing. It exercises jurisdiction over 22 provinces; five autonomous regions; four direct-controlled municipalities (Beijing, Tianjin, Shanghai and Chongqing); two mostly self-governing special administrative regions (Hong Kong and Macau); and claims sovereignty over Taiwan.

Covering approximately 9.6 million square kilometers, China is the world's second-largest country by land area, and either the third or fourth-largest by total area, depending on the method of measurement. China's landscape is vast and diverse, ranging from forest steppes and the Gobi and Taklamakan deserts in the arid north to subtropical forests in the wetter south. The Himalaya, Karakoram, Pamir and Tian Shan mountain ranges separate China from South and Central Asia. The Yangtze and Yellow Rivers, the third- and sixth-longest in the world, run from the Tibetan Plateau to the densely populated eastern seaboard. China's coastline along the Pacific Ocean is 14,500 kilometres (9,000 mi) long, and is bounded by the Bohai, Yellow, East and South China Seas.

Opium

Opium (poppy tears, lachryma papaveris) is the dried latex obtained from the opium poppy (Papaver somniferum). Opium latex contains approximately 12% of the analgesic alkaloid morphine, which is processed chemically to produce heroin and other synthetic opioids for medicinal use and for the illegal drug trade. The latex also contains the closely related opiates codeine and thebaine and non-analgesic alkaloids such as papaverine and noscapine. The traditional, labor-intensive method of obtaining the latex is to scratch ("score") the immature seed pods (fruits) by hand; the latex leaks out and dries to a sticky yellowish residue that is later scraped off, and dehydrated. The word "meconium" (derived from the Greek for "opium-like", but now used to refer to infant stools) historically referred to related, weaker preparations made from other parts of the opium poppy or different species of poppies.

The production of opium itself has not changed since ancient times. Through selective breeding of the Papaver somniferum plant, the content of the phenanthrene alkaloids morphine, codeine, and to a lesser extent thebaine, has been greatly increased. In modern times, much of the thebaine, which often serves as the raw material for the synthesis for hydrocodone, hydromorphone, and other semisynthetic opiates, originates from extracting Papaver orientale or Papaver bracteatum.
