 HIS: 1839 – The United Kingdom captures Hong Kong as a base as it prepares for the First Opium War with Qing China.

In the 18th century the 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 Canton. 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, drained the economy of silver, and increased the numbers of opium addicts inside the country, outcomes that seriously worried Chinese officials.

In 1839, the Daoguang Emperor, rejecting proposals to legalise and tax opium, appointed viceroy Lin Zexu to go to Canton to halt the opium trade completely. Lin wrote an open letter to Queen Victoria, which she never saw, appealing to her moral responsibility to stop the opium trade. Lin then resorted to using force in the western merchants' enclave. He confiscated all supplies and ordered a blockade of foreign ships on the Pearl River. Lin also confiscated and destroyed a significant quantity of European opium. The British government responded by dispatching a military force to China and in the ensuing conflict, the Royal Navy used its naval and gunnery power to inflict a series of decisive defeats on the Chinese Empire, a tactic later referred to as gunboat diplomacy. In 1842, the Qing dynasty was forced to sign the Treaty of Nanking—the first of what the Chinese later called the unequal treaties—which granted an indemnity and extraterritoriality to British subjects in China, opened five treaty ports to British merchants, and ceded Hong Kong Island to the British Empire. The failure of the treaty to satisfy British goals of improved trade and diplomatic relations led to the Second Opium War (1856–60). The following social unrest within China was the background for the Taiping Rebellion, which further weakened the dynasty. In China, the year 1839 is considered the beginning of modern Chinese history.
