Rattanakosin Kingdom (1782–1932)
The Rattanakosin Kingdom, also known as the Kingdom of Siam after 1855, refers to the Siamese kingdom between 1782 and 1932. It was founded in 1782 with the establishment of Rattanakosin, which replaced the city of Thonburi as the capital of Siam. This article covers the period until the Siamese revolution of 1932.
The kingdom governed based on the mandala system. This allows for high-autonomy locally with the kingdom influencing and effectively ruling its area of suzerainty. At its zenith in 1805 to 1812, the Kingdom was composed of 25 polities, ranging from duchies and principalities to federations and kingdoms. With the furthest extent reaching the Shan States, southern Yunnan, Laos, Cambodia, northern Si Rat Malai and Kawthoung. The kingdom was founded by Rama I of the Chakri dynasty. The first half of this period was characterized by the consolidation of Siamese power in the center of Mainland Southeast Asia and was punctuated by contests and wars for regional supremacy with rival powers Burma and Vietnam. The second period was one of engagements with the colonial powers of Britain and France in which Siam remained the only Southeast Asian state to maintain its independence.
Internally, the kingdom developed into a centralized, absolutist, nation state with borders defined by interactions with Western powers. The period was marked by the increased centralization of the monarch's powers, the abolition of labor control, the transition to an agrarian economy, the expansion of control over distant tributary states, the creation of a monolithic national identity, and the emergence of an urban middle class. However, the failure to implement democratic reforms culminated in the Siamese revolution of 1932 and the establishment of a constitutional monarchy.
Etymology
Rattanakosin is the proper term used by Thai historiography to cover the historical period of the first seven Chakri rulers, between the founding of Bangkok as the capital city of Thailand in 1782 and the end of the absolute monarchy in 1932, and was therefore never the official name of the country historically. The name Rattanakosin was first coined as part of the full name of Bangkok during the reign of Rama IV.Diplomatically, from the Ayutthaya Era until 1938, and later temporarily reinstated in 1946, Thailand was internationally recognized by the name "Siam".
In some 19th century foreign documents, Siam was alternatively referred to as "Ayutthaya" or "Siam-Ayutthaya".
History
Early Rattanakosin period (1782–1855)
Foundation of Bangkok
Chakri ruled under the name Ramathibodi, but was generally known as King Rama I, he moved the royal seat from Thonburi on the west bank of Chao Phraya River to the east bank, to the village of Bang Makok, meaning "place of olive plums". This was done due to its better strategic position in defenses against Burmese invasions from the West, the area was protected from attack by the river to the west and by a series of canals to the north, east and south. The east bank was surrounded by low marshlands inhabited by the Chinese, whom King Rama I ordered to move to Sampheng. The official foundation date of Bangkok is 21 April 1782 when the city pillar was consecrated in a ceremony. King Rama I underwent an abbreviated form of coronation in 1782. He founded the Chakri dynasty and made his younger brother Chao Phraya Surasi the Wangna or Prince Sura Singhanat of the Front Palace. In 1783, the Bangkok city walls were constructed with part of the bricks taken from the Ayutthaya ruins. Lao and Cambodian laborers were assigned to dig the city moat. The Grand Palace and the Wat Phra Kaew were completed in 1784 and the Emerald Buddha was transferred from Wat Arun to be placed in Wat Phra Kaew. In 1785, King Rama I performed a full coronation ceremony and named the new city "Rattanakosin", which meant the "Jewel of Indra" referring to the Emerald Buddha.Burmese wars
The Burmese continued to pose a major threat to the Siamese state of existence. In 1785, King Bodawpaya of the Burmese Konbaung dynasty sent massive armies to invade Siam in five directions during the Nine Armies' War. Decades of continuous warfare had left Siam depopulated and the Siamese court managed to muster only a total of 70,000 men against the 144,000 men of Burmese invaders. The Burmese, however, were over-stretched and unable to converge. Prince Sura Singhanat led his army to defeat the main army of King Bodawpaya in the Battle of Latya in Kanchanaburi in 1786. In the north, the Burmese laid siege on Lanna Lampang. Kawila, the ruler of Lampang, managed to hold the siege for four months until relief forces from Bangkok came to rescue Lampang. In the south, Lady Chan and Lady Mook were able to fend off Burmese attacks on Thalang in 1786. After the unfruitful campaign, King Bodawpaya sent his son Uparaja Thado Minsaw to invade Kanchanaburi concentrating only in one direction. King Rama I and his brother Prince Sura Singhanat defeated the Burmese in the Tha Dindaeng Campaign in 1786–1787.After these victories over Burmese invaders, Siam staged offensives on the Tenasserim Coast, which was the former territory of Ayutthaya. King Rama I marched Siamese armies to lay siege on Tavoy in 1788 but did not succeed. In 1792, the Burmese governors of Tavoy and Mergui defected to Siam. Siam came to temporarily occupy the Tenasserim Coast. However, as the court was preparing for the invasions of Lower Burma, King Bodawpaya sent his son Thado Minsaw to reclaim Tenasserim. The Siamese were soundly defeated by the Burmese in the Battle of Tavoy in 1793 and ceded the Tenasserim Coast to Burma for perpetuity, becoming modern Tanintharyi Division.
Lord Kawila was finally able to re-establish Chiang Mai as the centre of Lanna in 1797. King Bodawpaya was eager to regain Burmese control over Lanna. The Burmese invaded Chiang Mai in 1797 and 1802, in both occasions Kawila defended the city and Prince Sura Singhanat marched north to relieve Chiang Mai. The Siamese and Lanna forces then proceeded to capture Chiang Saen, the stronghold of Burmese authority in Lanna, in 1804, eliminating Burmese influence in that region. Siamese victories over the Burmese in Lanna allowed Siam to expand domination north towards the northernmost Tai princedoms: Keng Tung and Chianghung. Kawila of Chiang Mai sent forces to raid Keng Tung in 1802 and subjugated Mong Yawng, Mueang Luang Phukha, and Chiang Hung in 1805. In 1805, the Prince of Nan invaded the Tai Lue confederacy of Sipsongpanna and Chiang Hung surrendered.
Prince Sura Singhanat died in 1803. King Rama I appointed his own son Prince Itsarasunthon as the succeeding Prince of the Front Palace in 1806. King Rama I died in 1809 and Prince Itsarasunthon ascended the throne to become King Rama II. King Bodawpaya then took the opportunity to initiate the Burmese invasion of Thalang on the Andaman Coast. Meanwhile, the court in Bangkok sent armies to relieve Thalang but faced logistic difficulties and Thalang fell to the Burmese in 1810. However, the Siamese were still able to repel the Burmese from Thalang. The Burmese invasion of Phuket in 1809–1810 was the last Burmese incursion into Siamese territories in Thai history. Siam remained vigilant of prospective Burmese invasions through the 1810s. Only when Burma ceded Tenasserim to the British in the Treaty of Yandabo in 1826 in the aftermath of the First Anglo-Burmese War that Burmese threats effectively ended.
Siamese–Vietnamese Wars
When Siamese forces took Vientiane in 1779 during the Thonburi period, all three Lao kingdoms of Luang Phrabang, Vientiane and Champasak came under Siamese domination. Lao Princes Nanthasen, Inthavong and Anouvong were taken as hostages to Bangkok. In 1782, King Rama I installed Nanthasen as King of Vientiane. However, Nanthasen was dethroned in 1795 due to his alleged diplomatic overtures with the Tây Sơn dynasty in favor of Inthavong. When King Inthavong died in 1804, Anouvong succeeded as King of Vientiane.Yumreach Baen, a pro-Siamese Cambodian noble, staged a coup in Cambodia to overthrow and kill the pro-Vietnamese Cambodian Prime Minister Tolaha Mu in 1783. Chaos and upheavals that ensued caused Yumreach Baen to take young King Ang Eng to Bangkok. King Rama I appointed Yumreach Baen as Chaophraya Aphaiphubet. Also in 1783, Nguyễn Phúc Ánh arrived in Bangkok to take refuge from the Tây Sơn rebels. In 1784, Siamese forces invaded Saigon to reinstate Nguyễn Phúc Ánh but were defeated in the Battle of Rạch Gầm-Xoài Mút by the Tây Sơn. In 1789, Aphaiphubet took control of Cambodia and became the Regent. Later that same year Nguyễn Phúc Ánh took Saigon and established himself in Southern Vietnam. In 1794, King Rama I allowed Ang Eng to return to Cambodia to rule as king and carved the northwestern part of Cambodia including Battambang and Siemreap for Aphaiphubet to govern as governor under direct Siamese rule.
King Ang Eng of Cambodia died in 1796 and was succeeded by his son Ang Chan II who became pro-Vietnamese. While the pro-Siamese Prince Ang Sngoun, younger brother of Ang Chan II, decided to rebel against his brother in 1811. The Siamese forces marched from Battambang to Oudong. The panicked King Ang Chan II fled to take refuge at Saigon under the protection of Vietnam. Siamese forces sacked Oudong and returned. Lê Văn Duyệt brought Ang Chan II back to Phnom Penh to rule under Vietnamese influence.
King Anouvong of Vientiane rebelled against Siam in 1827. He led the Lao armies to capture Nakhon Ratchasima and Saraburi, while his son King Raxabut Nyô of Champasak invaded Southern Isan. Phraya Palat and his wife Lady Mo led the Siamese captives to rise against their Lao overseers in the Battle of Samrit Fields. King Rama III sent Prince Sakdiphonlasep of the Front Palace to defeat Anouvong at Nong Bua Lamphu and Phraya Ratchasuphawadi to capture Raxabut Nyô. Anouvong and his family fled to Nghệ An Province of Vietnam under protection of Emperor Ming Mạng. Ming Mạng sent Anouvong back to Vientiane to negotiate with Siam. However, Anouvong retook control of Vientiane only to be pushed back by Phraya Ratchasuphawadi in 1828. Anouvong was eventually captured and sent to Bangkok where he was imprisoned and died in 1829.
Anouvong's rebellion worsened Siamese-Vietnamese relations. Lê Văn Duyệt died in 1832 and his posthumous punishments by Ming Mạng spurred the Lê Văn Khôi rebellion at Saigon in 1833. King Rama III took the opportunity to eliminate Vietnamese influence in the region. He assigned Chaophraya Bodindecha to lead armies on invading Cambodia and Saigon, while Chaophraya Phrakhlang led the fleet. However, the Siamese forces were defeated in the naval Battle of Vàm Nao and retreated. The Siamese defeat confirmed Vietnamese domination over Cambodia. Ming Mạng annexed Cambodia into Trấn Tây Province with Trương Minh Giảng as the governor. After the death of Ang Chan II, Minh Mạng also installed Ang Mey as puppet queen regnant of Cambodia. In 1840, the Cambodians arose in general rebellion against Vietnamese domination. Bodindecha marched Siamese armies to attack Pursat and Kampong Svay in 1841. The new Vietnamese Emperor Thiệu Trị ordered the Vietnamese to retreat and the Siamese took over Cambodia. The war resumed in 1845 when Emperor Thiệu Trị sent Nguyễn Tri Phương to successfully take Phnom Penh and lay siege on Siamese-held Oudong. After months of siege, Siam and Vietnam negotiated for peace with Prince Ang Duong, who would recognize both Siamese and Vietnamese suzerainty, installed as the new King of Cambodia in 1848.
