The Opium Wars & the 'century of humiliation'
The Opium Wars, the unequal treaty system, and the founding narrative of the 'century of humiliation' (1839-1949) for the Guokao modern-history paper.
The Canton System and the Opium Trade
Before 1842, Sino-Western trade was confined to Guangzhou (Canton) under the Canton System, where foreign merchants dealt only through the licensed Cohong (公行) guild and were barred from direct contact with officials. Britain ran a structural trade deficit: it craved Chinese tea, silk, and porcelain, but China demanded payment in silver and wanted little British manufacture. The British East India Company resolved the imbalance by smuggling Indian-grown opium into China, reversing the silver flow. By the 1830s opium imports drained Qing silver reserves, debased the copper-silver exchange, and addicted millions.
The Daoguang Emperor dispatched Commissioner Lin Zexu (林则徐) to Guangzhou in 1839. Lin confiscated and destroyed roughly 1,000 tonnes (some 20,000 chests) of British opium at Humen (Hu Men) in June 1839, and wrote his celebrated remonstrance to Queen Victoria. Britain, framing the dispute as one of free trade and national honour, dispatched an expeditionary force.
The First Opium War (1839-1842)
British naval and industrial superiority — steam gunboats such as the Nemesis — overwhelmed Qing coastal defences. The war ended with the Treaty of Nanjing (Nanking), 29 August 1842, China's first 'unequal treaty.' Its terms: cession of Hong Kong Island to Britain; opening of five treaty ports (Guangzhou, Xiamen/Amoy, Fuzhou, Ningbo, Shanghai); an indemnity of 21 million silver dollars; and abolition of the Cohong monopoly. The supplementary Treaty of the Bogue (Humen, 1843) added extraterritoriality (consular jurisdiction over British subjects) and the most-favoured-nation clause, which automatically extended any concession granted to one power to all. The United States secured the Treaty of Wangxia (1844) and France the Treaty of Huangpu (1844) on identical lines.
The Second Opium War (1856-1860)
Western powers sought wider access. Using the Arrow Incident (October 1856) as a pretext, Britain — joined by France after the killing of the missionary Auguste Chapdelaine — waged the Second Opium War. The Treaties of Tianjin (Tientsin), 1858 opened more ports, legalised opium, permitted foreign legations in Beijing, and admitted Christian missionaries to the interior. When the Qing resisted ratification, an Anglo-French force marched on the capital and burned the Old Summer Palace (Yuanmingyuan) in October 1860. The Convention of Beijing (1860) ceded Kowloon to Britain and, in a separate treaty, transferred the Outer Manchurian territories north of the Amur and east of the Ussuri to Russia — the largest single loss. These wars inaugurated the treaty-port order that defined China's external subjugation for a century.
