Second Opium War

Second Opium War. Also known as the Arrow War or the Anglo-French expedition to China, this conflict was a pivotal chapter in the Century of Humiliation for the Qing dynasty. Fought primarily by the British Empire and the Second French Empire against China, it resulted in the further weakening of imperial authority and the imposition of a new series of unequal treaties. The war decisively opened China to foreign influence and trade, cementing Western economic and legal privileges.

Background and causes

The primary catalyst was the unresolved commercial and diplomatic tensions following the First Opium War and the Treaty of Nanking. Western powers, particularly Britain and France, sought to revise the treaties to expand trade, legalize the opium trade, and gain diplomatic representation in Beijing. The immediate incident occurred in October 1856 with the Arrow Incident, where Chinese officials in Guangzhou boarded the lorcha Arrow, a vessel registered in Hong Kong, and arrested its Chinese crew. British officials, including Harry Smith Parkes, claimed this violated the treaty and insulted the British Empire. Concurrently, the French Empire used the execution of a French missionary, Auguste Chapdelaine, in Guangxi as a casus belli. The declining Qing dynasty was simultaneously embroiled in the massive Taiping Rebellion, which severely strained its military and fiscal resources.

Course of the war

Hostilities began in late 1856 with naval action by the Royal Navy under Admiral Michael Seymour against forts in the Pearl River Delta. The capture of Guangzhou in December 1857 by a joint Anglo-French force led to the arrest of the Viceroy of Liangguang, Ye Mingchen. In 1858, forces moved north, leading to the capture of the Taku Forts guarding the approach to Tianjin. This prompted the Qing court to negotiate, resulting in the Treaty of Tientsin in June 1858. When China later resisted ratifying the treaty and refused entry to Beijing, hostilities resumed in 1859. A major Anglo-French expedition was launched in 1860 under Lord Elgin and Jean-Baptiste Louis Gros. After a decisive victory at the Battle of Palikao, the alliance occupied the capital. The Xianfeng Emperor fled to the Chengde Mountain Resort, leaving his brother Prince Gong to negotiate.

Treaties and aftermath

The war concluded with the signing of the Convention of Peking in October 1860, which ratified the earlier Treaty of Tientsin. Key provisions included the opening of eleven additional treaty ports like Tianjin, Nanjing, and Hankou; the legalization of the opium trade; freedom of movement for Christian missionaries; and the establishment of permanent diplomatic legations in Beijing. The Kowloon Peninsula was ceded to Britain. Furthermore, Russia, represented by diplomat Nikolay Ignatyev, secured the vast Amur and Primorsky territories through the Treaty of Aigun and the Convention of Peking, acquiring the site of future Vladivostok. The indemnity imposed on the Qing government exacerbated its financial crisis, and foreign influence became entrenched within the imperial court.

Legacy and historical assessment

The conflict marked a profound shift in Sino-foreign relations, solidifying the treaty system and deepening foreign imperialist control over China's economy and sovereignty. The sacking of the Old Summer Palace (Yuanmingyuan) by British and French troops became a lasting symbol of national humiliation in Chinese historical memory. The war significantly weakened the Qing dynasty, emboldening regional rebellions like the Taiping Rebellion and the Nian Rebellion, and set the stage for the later Self-Strengthening Movement. Historians view it as a critical juncture that accelerated the decline of imperial China and intensified the scramble for concessions by foreign powers, including Japan, leading toward the Boxer Rebellion of 1900.
