In 1853, northern China was convulsed by the Taiping Rebellion, which established its capital at Nanjing. In spite of this, a new Imperial Commissioner, Ye Mingchen, was appointed at Canton, determined to stamp out the opium trade, which was still technically illegal. In October 1856, he seized the Arrow, a ship claiming British registration, and threw its crew into chains. Sir John Bowring, Governor of British Hong Kong, called up Rear Admiral Sir Michael Seymour's East Indies and China Station fleet, which, on 23 October, bombarded and captured the Pearl River forts on the approach to Canton and proceeded to bombard Canton itself, but had insufficient forces to take and hold the city. On 15 December, during a riot in Canton, European commercial properties were set on fire and Bowring appealed for military intervention. The execution of a French missionary inspired support from France. The United States and Russia also intervened in the war.
