The Island Across the Strait: When the First Han Voyagers Met Formosa

The sea between the southeastern coast of China and the island of Taiwan is notoriously fickle. For centuries, the Taiwan Strait was a barrier of treacherous currents, sudden typhoons, and dense mists. To the emperors of the Ming and Song dynasties, the rugged, emerald island rising on the eastern horizon was a wild, untamed frontier—an island outside the civilized world, populated by indigenous Austronesian tribes who had called its mountains and plains home for millennia.

Yet, necessity and opportunity have a way of conquering geography. Long before colonial flags were planted on its shores, the first interactions between Han Chinese travelers and Taiwan began not with imperial conquest, but with the quiet rhythm of the tides and the desperate search for survival.

The Seasonal Pioneers

The earliest chapter of Chinese interaction with Taiwan wasn’t written by soldiers, but by seasonal fishermen and merchants from the coastal provinces of Fujian and Guangdong.

By the 12th century, Southern Song dynasty fishermen had already established a foothold in the Penghu Islands (the Pescadores), the small archipelago sitting halfway across the strait. Penghu served as a crucial stepping stone. It was flat, manageable, and strategically positioned. By 1171, the Song court had even stationed a small military presence there to deter raids.

From Penghu, it was only a short sail to the main island of Taiwan. By the 15th and 16th centuries, Han traders were making regular seasonal voyages to Taiwan’s southwestern coast, near modern-day Tainan.

They weren’t looking to conquer; they were looking to trade. The island’s vast forests were teeming with Formosan sika deer. Han merchants brought porcelain, iron cooking pots, textiles, and salt to exchange with the indigenous tribes for highly prized deerskin, venison, and medicinal herbs. Once the trading season ended, the merchants packed their ships and caught the monsoon winds back to the mainland.

As the Ming dynasty began to fracture, control over the waters shifted from imperial navies to brilliant, rogue opportunists. Foremost among them was Zheng Zhilong (also known as Nicholas Iquan), a master merchant-pirate whose life read like an international thriller.

Born in Fujian, Zheng was a linguistic prodigy and a chameleon. He moved to Macau, converted to Catholicism, and worked as a translator for the Dutch East India Company (VOC) in the Pescadores. But Zheng saw bigger horizons. He quickly amassed a private fleet, systematically defeating rival pirate lords until he commanded tens of thousands of men and a fleet that dominated the South China Sea.

Zheng realized early on that Taiwan was the ultimate unchecked logistics base. When a catastrophic famine struck Fujian in the late 1620s, Zheng executed a masterstroke of private enterprise and humanitarian pragmatism. He funded the transport of more than 3,000 starving mainlanders across the strait, providing each family with three taels of silver and an ox to clear the fields of southwestern Taiwan. By doing so, Zheng did what no Chinese emperor had ever bothered to do: he planted the first massive, permanent Han roots on the island. Later, he legitimized his empire by accepting an admiral’s commission from the desperate Ming court, transforming his pirate fleet into the official enforcers of the strait.

Life Under the Company: The Dutch Era

If Zheng Zhilong lit the spark of permanent settlement, a global mega-corporation poured fuel on it. In 1624, the Dutch East India Company established a foothold at Fort Zeelandia in modern-day Anping, Tainan.

The Dutch corporate brass envisioned Taiwan as a massive, lucrative engine for sugar and rice exports to Japan and Europe. But they hit an immediate bottleneck: the island’s indigenous populations had no interest in entering a system of currency-driven, intensive plantation labor. To solve this, the VOC turned to the mainland, actively recruiting destitute Han laborers from Fujian with promises of free land, tax exemptions for their first few years, and protection from coastal raiders.

For the Han pioneers who crossed the sea, daily life under the Dutch was a grinding, high-stakes gamble. It was defined by:

• The Hunt for “White Gold”: Laborers cleared dense subtropical wilderness to plant sugarcane and rice. The work was grueling, hot, and plagued by malaria.
• Strict Company Oversight: The Dutch did not rule gently. Every single deer hide caught, pound of sugar refined, or fish hooked was subject to meticulous corporate monopolies and heavy taxes.
• Boiling Tensions: Han settlers held no political rights and were subjected to arbitrary poll taxes. Tensions between the hard-pressed Chinese workers and the strict Calvinist Dutch overseers eventually exploded in 1652 with the Guo Huaiyi Rebellion. Driven by economic desperation, thousands of Han farmers armed with little more than bamboo spears and farming tools rose up against the garrison. The rebellion was brutally crushed by Dutch forces aided by indigenous allies, leaving thousands of settlers dead.

The Hidden Foundation

Despite the harshness of colonial rule, the Dutch era permanently shifted Taiwan’s demographic gravity. By the time the colony collapsed, the wild frontier had been mapped, irrigation systems had been dug, and tens of thousands of Han laborers had made the soil of Formosa their home.

A Legacy Set in Stone

What began as fishermen mending nets on temporary beaches eventually grew into an irreversible migration. By the time Zheng Zhilong’s legendary son, Koxinga (Zheng Chenggong), used his father’s old maritime networks to expel the Dutch in 1662 and establish the Kingdom of Tungning, the cultural template of western Taiwan was already deeply set.

The story of the first Chinese interactions with Taiwan is not a tale of sudden imperial decree. It is a story shaped by the rugged pragmatism of coastal laborers, the geopolitical maneuvering of a European global corporation, and the shadow diplomacy of maritime outlaws like Zheng Zhilong—a slow, steady bridging of the strait that changed the island of Formosa forever.
