  Passage: Opium Wars is a collective term for the mid-1800s conflicts between Western powers and China including the First Opium War (1839–1842) and the Second Opium War (1856–1860).
  Title: Opium Wars
  Passage: The Opium Wars were two wars in the mid-19th century involving Anglo-Chinese disputes over British trade in China and China's sovereignty.  The disputes included the First Opium War (1839–1842) and the Second Opium War (1856–1860).  The wars and events between them weakened the Qing dynasty and forced China to trade with the other parts of the world.
  Title: Thirteen Factories
  Passage: The Thirteen Factories also known as the Canton Factories , was a neighbourhood along the Pearl River in southwestern Guangzhou in the Qing Empire from c. 1684 to 1856.  These warehouses and stores were the principal and sole legal site of most Western trade with China from 1757 to 1842.  The factories were destroyed by fire in 1822 by accident, in 1841 amid the First Opium War, and in 1856 at the onset of the Second Opium War.  The factories' importance diminished after the opening of the treaty ports and the end of the Canton System under the terms of the 1842 Anglo-Chinese Treaty of Nanking.  After the Second Opium War, the factories were not rebuilt at their former site south of Guangzhou's old walled city but moved, first to Henan Island across the Pearl River and then to Shamian Island south of Guangzhou's western suburbs.  Their former site is now part of Guangzhou Cultural Park .
  Title: Transfer of sovereignty over Macau
  Passage: The transfer of sovereignty of Macau from the Portuguese Republic to the People's Republic of China (PRC) occurred on 20 December 1999.  Macau was settled and governed by Portuguese merchants in 1535, during the Ming Dynasty (1368–1644 AD).  Portugal's involvement in the region was formally recognized by the Qing in 1749.  The Portuguese governor, emboldened by the First Opium War and the Treaty of Nanking, attempted to annex the territory, expelling Qing authorities in 1846, but was assassinated.  After the Second Opium War, the Portuguese government, along with a British representative, signed the Sino-Portuguese Treaty of Peking that gave Portugal sovereignty over Macau, on the condition that Portugal would cooperate in efforts to end the smuggling of opium.

  Title: Battle of Chinkiang
  Passage: The Battle of Chinkiang was fought between British and Chinese forces in Chinkiang (Zhenjiang), Jiangsu province, China, on 21July 1842 during the First Opium War.  It was the last major battle of the war.  The Chinese force consisted of a garrison of Manchu and Mongol Bannermen.  In command of the British forces was Sir Hugh Gough.  Leading one brigade was future British field marshal Sir Colin Campbell.  The British capture of this stronghold allowed them to proceed to Nanking.  Fought near the confluence of the Grand Canal and Yangtze River, the battle effectively blocked operation of the Caoyun system, a transport network vital for the movement of grain throughout the empire.  As a result, the Daoguang Emperor decided to sue for peace and agreed to sign the Treaty of Nanking, which brought hostilities to an end.  Mass suicide was committed by the Manchu Bannermen who were defending the city.
  Title: Lin Zexu
  Passage: Lin Zexu (30 August 1785 – 22 November 1850), courtesy name Yuanfu, was a Chinese scholar-official of the Qing dynasty best known for his role in the First Opium War of 1839–42.  He was from Fuzhou, Fujian Province.  Lin's forceful opposition to the opium trade was a primary catalyst for the First Opium War.  He is praised for his constant position on the "moral high ground" in his fight, but he is also blamed for a rigid approach which failed to account for the domestic and international complexities of the problem.  The Daoguang Emperor endorsed the hardline policies advocated by Lin, but then blamed Lin for the resulting disastrous war.
