Chapter 51: The Ayutthaya Awakening
On the surface, the Iberian-Japanese War completely changed the power balance in Southeast Asia from a modest Iberian preeminence to unchallengeable Dutch-Japanese dominance. Although the Dutch and Japanese and their Muslim allies undoubtedly made real gains at the expense of Spain and Portugal, the coalition was nevertheless formed largely against a common enemy and not around any mutual ties. Those keenly observant of the outcome from the outside could see this and would act accordingly towards new opportunities the postwar balance of power offered, causing a diplomatic realignment within the region. In this landscape, Siam, already a powerful kingdom with a storied history, would see itself rising towards even greater heights, beginning in a period following the war that would later be dubbed the “Ayutthaya Awakening”.
Under the reign of Si Saowaphak, Siam solidified trade relations with the Dutch and English, having previously sent an embassy to the former under the reign of the king’s father, Ekathotsarot. The kingdom also welcomed an official delegation from Azuchi in 1622, building upon a foundation of ties and trade with Japan forged by the support of the Honjo clan and the presence of the largest Nihonmachi across Southeast Asia located inside Ayutthaya. Under the military expertise of Honjo Mitsunaga, one of the king’s closest advisors, Si Saowaphak also warded off a Taungoo invasion of Tavoy and quashed an attempt by Cambodian king Chey Chettha II and the Vietnamese Nguyen lords to break the former’s realm from Siamese vassalage, dethroning the monarch and installing his younger brother Outey as the new king [1]. His relatively successful reign abruptly ended at the hands of anti-Japanese nobles resentful of the disproportionate influence of the Honjo clan and Japanese merchants in the country, who would then install the 13 year old crown prince Athittayawong. Afterwards, the Honjo clan and other prominent Japanese in the kingdom would leave the government and be sidelined, not only hurting trade and diplomatic relations with Azuchi but setting the kingdom up for internal and external conflict for years to come. Taking advantage of the internal disorder within the Siamese court, Chey Chettha II’s son Ponhea To overthrew his uncle in 1625 with the backing of the Nguyen lords and became King Thommo Reachea II of Cambodia, simultaneously throwing off the yoke of Siamese vassalage. Over the course of the 3 year war between Cambodia and Siam, the Honjo clan and its sizable retinue would leave Ayutthaya and defect to Thommo Reachea. With theirs and the Nguyen lord’s support, Cambodia subsequently gained full independence from Siam. This betrayal would create a hatred of the Honjo clan and the Japanese in the Siamese court, the two sides continuing to fight even after the conclusion of what would be later called the 2nd Siamese-Cambodian War [2]. Through the advice of Spanish advisors from Manila and the xenophobia of Athittayawong’s court, the trading privileges of Japanese merchants across the realm, including in the capital city of Ayutthaya, were revoked. The Nihonmachi itself experienced economic turmoil and rounds of persecution by the kingdom, its destruction only prevented by Azuchi’s intervention and its promise not to aid the Honjo clan in its efforts against the Siamese kingdom.
Years of unsuccessful campaigns and political instability began to take a long-term toll on Siam. The court became so preoccupied with fighting pro-Honjo rebels and Cambodia that it was unable to stop the Sultanate of Patani from refusing to pay tribute or attacking the southern port cities of Phatthalung and Ligor. Dissatisfaction with the new regime increased throughout the kingdom, even among those who had supported the coup. In this environment, yet another coup would take place and politics would shift once more. This time, the king’s first cousin once removed Prasat Thong would be the one to assassinate the king and take charge in 1630. Determined to turn his kingdom around, the new king immediately entered into peace talks with Honjo Nagafusa (本庄長房), the Honjo clan head, upon his accession and brokered a treaty between the kingdom and the samurai clan, bringing the Honjo faction back into the Siamese fold and restoring some trading privileges to the Japanese merchants in Ayutthaya. Prasat Thong also dismissed many of the Spanish advisors present at the royal court and refused to get Siam involved in the Iberian-Japanese War despite lobbying from Manila, maintaining a more neutral relationship with the Iberian powers. With the kingdom lessened of foreign influence and on more stable footing, the king would be able to focus on subjugating Patani once again as a tributary, which was accomplished by 1634 [3].

It was amidst this upswing in Siamese fortunes that the Iberian-Japanese War concluded, seeing the Dutch-Japanese coalition gain lands and economic concessions from the Iberian Union. Understanding the power shift that had taken place and how the political imbalance could negatively affect Siam in the future, Prasat Thong embarked upon a programme of political reforms and diplomatic endeavors to strengthen the kingdom over many years. Most significantly, he reformed the military, increasing the number of arquebusiers and cannons in the army and beginning to incorporate purchased European-style warships into the Siamese navy. Native mortars crafted from a fusion of Siamese and European metallurgy would in particular play a large role in the newly modernized military, transported from location to location by Asian elephants. Meanwhile, the Honjo clan and their retinue would formally become a designated elite unit of cavalry within the army rather than as an auxiliary force. This not only increased rapport with the Japanese in Siam and bolstered the military’s effectiveness but also decreased the political autonomy of the Honjo clan, increasing the central authority of the monarchy while easing remaining tensions between Siamese nobles and the Japanese.
Prasat Thong also increased commercial activity between Siam and the recently defeated Iberian powers, recognizing a newly existent demand for Oriental goods and resources caused by the loss of Macau and subsequent expanded Japanese control of trade between the Ming and Europeans. In time, this move would induce closer diplomatic relations with Spain and Portugal away from the Dutch but from a place of equal standing rather than as a pawn of European schemes and designs. Internally, Prasat Thong instituted a regime of law and order in the kingdom to suppress disorder , even known to carry out executions himself, and formally changed Siamese royal succession laws toward male primogeniture as opposed to the previous primacy of male siblings. He also centralized the government bureaucracy and reduced the power of the nobility to avoid a repeat of the civil strife the realm had been embroiled in so recently.
Prasat Thong’s reforms in the decade after the Treaty of Gapan in response to political changes abroad significantly expanded the power of his kingdom and would lead to Siam becoming a regional power rivaling even the might of Azuchi down the line, preventing itself from becoming subservient to a foreign power for the rest of the 17th century. This particular period would be referred to as the “Ayutthaya Awakening”, a time when the Siamese realm was awakened to and prepared for opportunities beyond its shores and surroundings. As it turned out, beyond this “awakening” period, Prasat Thong would begin to seize upon such opportunities later on during his reign.
