d by American coins) as they contained higher amounts of silver. Using western coins allowed Cantonese coiners to make many Chinese coins from melted-down western coins, greatly increasing the city's wealth, and tax revenue while tying much of the economy of the city to the foreign merchants.
A significant development came in 1834 when reformers (some of whom were financially backed by Jardine) in Britain, advocating for free trade, succeeded in ending the monopoly of the British East India Company under the Charter Act of the previous year. This shift in trade policy ended the need for merchants to comply with the royal charter for trade in the far east; with this centuries-old restriction lifted, the British China trade was opened to private entrepreneurs, many of whom joined the highly profitable opium trade.
On the eve of the Qing government's crackdown on opium, a Chinese official described the changes in society caused by the drug;
At the beginning, opium smoking was confined to the fops of wealthy families who took up the habit as a form of conspicuous consumption, even they knew that they should not indulge in it to the greatest extreme. Later, people of all social strata—from government officials and members of the gentry to craftsmen, merchants, entertainers, and servants, and even women, Buddhist monks and nuns, and Taoist priests—took up the habit and openly bought and equipped themselves with smoking instruments. Even in the center of our dynasty—the nation's capital and its surrounding areas—some of the inhabitants have also been contaminated by this dreadful poison.
In late 1834, to accommodate the revocation of the East India Company's monopoly, the British sent Lord William John Napier to Macau along with John Francis Davis and Sir George Best Robinson, 2nd Baronet as British superintendents of trade in China. Napier was instructed to obey Chinese regulations, communicate directly with Chinese authorities, superintend trade pertaining to the contraband trade of opium, and to survey China's coastline. Upon his arrival in China, Napier tried to circumvent the restrictive system that forbade direct contact with Chinese officials by sending a letter directly to the Viceroy of Canton. The Viceroy refused to accept it, and on 2 September of that year an edict was issued that temporarily closed British trade. In response, Napier ordered two Royal Navy vessels to bombard Chinese forts on the Pearl River in a show of force. This command was followed through, but war was avoided due to Napier falling ill with typhus and ordering a retreat. The brief gunnery duel drew condemnation by the Chinese government, as well as criticism from the British government and foreign merchants. Other nationalities, such as the Americans, prospered through their continued peaceful trade with China, but the British were told to leave Canton for either Whampoa or Macau. Lord Napier was forced to return to Macau, where he died of typhus a few days later. After Lord Napier's death, Captain Charles Elliot received the King's Commission as Superintendent of Trade in 1836 to continue Napier's work of conciliating the Chinese.
In addition to the short term causes after 1838 described in this section, there also long-term factors that pushed the Chinese government into action. Historian Jonathan D. Spence lists these factors that led to war:
By 1838, the British were selling roughly 1,400 tons of opium per year to China. Legalization of the opium trade was the subject of ongoing debate within the Chinese administration, but a proposal to legalize the narcotic was repeatedly rejected, and in 1838 the government began to actively sentence Chinese drug traffickers to death.
In 1839, the Daoguang Emperor appointed scholar-official Lin Zexu to the post of Special Imperial Commissioner with the task of eradicating the opium trade. Lin wrote an open letter to Queen Victoria questioning the moral reasoning of the British government. Citing what he understood to be a strict prohibition of the trade within Great Britain, Lin questioned how Britain cou
