Spanish Northern Taiwan

In the pale dawn of 1626, as the Pacific monsoons swept across the northeastern cape of Formosa, several towering Spanish galleons flying the red-and-yellow imperial banners glided into the magnificent natural harbor known today as Keelung. Under the direct decrees of the Governor-General in Manila, these Catholic adventurers crossed the treacherous Luzon Strait to launch a forceful military landing on the island of Jilong (modern-day Heping Island). In the eyes of the Spaniards, this was far more than a routine voyage of discovery; it was a desperate, high-stakes geopolitical gambit engineered by Manila to counter the rapidly expanding global trade monopoly of the Dutch East India Company in southern Taiwan. The Spanish pioneers immediately constructed a massive redoubt of stone and heavy timber—Fort San Salvador—before extending their governing tentacles westward to Tamsui to erect Fort San Domingo. The cold steel and religious fervor of the Age of Sail had violently shattered the millennium-long slumber of northern Taiwan.

The strategic impetus behind this grand Spanish expedition northward was rooted in one of the most intense, blood-soaked rivalries of the colonial era. On the global oceans of the seventeenth century, the Protestant Dutch "Sea Beggars" were systematically cannibalizing the vast East Asian commercial networks that Spain and Portugal had painstakingly cultivated for over a century. When the Dutch firmly secured Fort Zeelandia at Tayouan in 1624, the golden maritime highway connecting Spanish Manila to Nagasaki, as well as the lucrative smuggling routes for Chinese silk along the Fujian coast, became directly exposed to the devastating cannon fire of VOC warships. Manila understood profoundly that if the red-haired heretics were permitted to hold exclusive dominion over Formosa, the commercial lifeblood of Spain's Far Eastern empire would be completely severed. Thus, Spain resolved to plant a formidable military and economic counter-bastion in northern Taiwan, intending to aggressively restructure their maritime empire.

In stark contrast to the highly bureaucratized and heavily institutionalized mercantile apparatus of the Dutch in the south, Spanish rule in northern Taiwan manifested a unique dual-track administrative model driven by a combination of military fortresses and evangelical fervor—the strategy of the cross and the musket. At the executive and military level, the successive Spanish governors dispatched to the north were tasked with the singular mission of defending Fort San Salvador while projecting martial intimidation over surrounding indigenous villages. However, because the central treasury in Manila was perennially bankrupt and consumed by relentless localized rebellions across Southeast Asia, the actual allocation of military provisions, bullion, and European soldiers to northern Taiwan remained severely restricted. Devoid of immense commercial capital or an expansive army, this isolated outpost suffered from crippling administrative stagnation, forcing the authorities to rely heavily on a different kind of power to sustain their grip on the frontier.

This spiritual vanguard was comprised of Catholic friars from the Dominican Order who landed alongside the garrison, driven by a passionate zeal for religious martyrdom. Clad in their distinctive black-and-white robes, these missionaries braved rampant tropical fevers, a hostile wilderness, and the fierce initial animosity of native tribes to venture deep into the plains of Keelung, Tamsui, and even into the hidden expanses of the Taipei Basin. The Dominicans demonstrated an extraordinary capacity for cultural adaptation, learning local dialects and compiling what became the world's very first comparative dictionaries between Spanish and Formosan indigenous languages, such as Basay. By erecting chapels and administering holy baptism across fragmented clans, these friars transformed themselves into the primary diplomatic bridge between the Spanish Crown and the indigenous populace. On countless occasions, a lone missionary wielding a crucifix and commanding the absolute trust of a village proved far more effective at pacifying the frontier than the cold, silent cannons lining the stone battlements of Fort San Salvador.

Yet, this ambitious colonial expansion directed from Manila was ultimately denied a permanent chapter in the history of the island. When the Tokugawa Shogunate of Japan enforced its draconian Sakoku (closed-country) edicts, completely outlawing the Catholic faith, Spain’s grand dream of utilizing northern Taiwan to force open the gates of Japanese commerce vanished overnight. Concurrently, Chinese merchant junks failed to arrive in Keelung in the anticipated volumes, saddleing both Fort San Salvador and Fort San Domingo with devastating annual fiscal deficits. By 1638, an emotionally and financially drained Governor-General in Manila resolved to execute a severe strategic contraction, ordering the deliberate demolition of Fort San Domingo in Tamsui and recalling the vast majority of Keelung's elite garrison and artillery back to the Philippines. This fatal order effectively crippled the northern defensive lines, reducing Spanish presence to a historical nadir.

Upon learning that the Spanish bastions had been left hollow and exposed, the Council of Tayouan in southern Taiwan moved without hesitation. In the sweltering midsummer of 1642, the Dutch Governor dispatched a powerful expeditionary fleet packed with frontline warships and hundreds of battle-hardened European soldiers to assault the north. A fierce, thunderous artillery duel erupted across the beaches and ridges of Heping Island. Though the remnants of the Spanish garrison inside Fort San Salvador fought with desperate bravery, they found themselves trapped in a hopeless material vacuum—starved of reinforcements, depleted of ammunition, and completely outgunned by superior Dutch weaponry. Left with no alternative, the garrison lowered the red-and-yellow imperial flag and opened the city gates in absolute capitulation. Spain's brief sixteen-year tenure in northern Taiwan reached its sudden, tragic end, vanishing into the ocean winds and the drifting smoke of Keelung.
