Tai-Pan is a 1966 novel written by James Clavell about European and American traders who move into Hong Kong in 1842, following the end of the First Opium War. It is the second book in Clavell's Asian Saga, and the first to include the fictional Struan family. At its heart is the conflict between Dirk Struan and Tyler Brock.

The novel begins following the British victory of the first Opium War and the seizure of Hong Kong. Although the island is largely uninhabited and the terrain unfriendly, it has a large natural harbour that both the British government and various trading companies believe will be useful for the import of merchandise to be traded in mainland China, a highly lucrative market.

In 1805, at the age of seven, Dirk Struan began his nautical adventures as a powder monkey on a king's ship at the Battle of Trafalgar and he remains bound to the sea for life. By the end of this year, he found service on the East India Company merchant ship Vagrant Star to China. Under the command of Tyler Brock, third mate and future nemesis, Dirk Struan was whipped mercilessly. Dirk Struan vowed to someday destroy Brock. Later, Dirk Struan and Tyler Brock would go on to dominate the opium trade.

In 1812 a fateful night in the Malacca Strait, Vagrant Star ran aground on a reef and sank. At the age of fourteen, Struan swam ashore and found his way to Singapore. Later, Dirk Struan discovered that Tyler Brock survived as well.

By 1822, Dirk Struan was a captain-owner of his own ship on the opium run. Tyler Brock was his chief rival. Also this year, Dirk Struan married Ronalda in Scotland, but immediately travelled to Macau.

In 1824, Culum Struan was born. He was the son of Dirk Struan and Ronalda. Shortly after his birth, Ronalda and Culum were sent to Glasgow. Ronalda would never return to China. Also this year, Gordon Chen was born. He was the illegitimate son of Dirk Struan and his mistress, Chen Kai Sung.

In 1826, the British East India Company decided to make an example of Struan and Brock. The Company withdrew their licenses and the two men were financially wiped out. Brock was left with his ship, Struan with nothing. Brock entered a secret agreement with another opium trader. Dirk Struan pilfered a lorcha from pirates in Macau. He became a clandestine opium smuggler for other China traders. He relentlessly confiscated more pirate ships. Using them to make dangerous illicit opium runs up the China coast, he made even greater profits.

In 1834, free trade reform advocates succeeded in ending the monopoly of the British East India Company under the Charter Act 1833. Finally, British trade opened to private entrepreneurs. With the freedom to legally trade, Dirk Struan and Tyler Brock became merchant princes. Their armed fleets expanded and bitter rivalry honed their enmity even keener.
