Thailand history dates back thousands of years, though the modern history of Thailand began with the founding of the Kingdom of Sukhothai.
Dating back to the Neolithic civilization situated at the modern-day UNESCO World Heritage Site in Ban Chiang, the history of Thailand is long, proud, and fairly well documented. Over the early centuries of the Common Era, tribes of Mon, Khmer, and Tai peoples established realms within the borders of modern Thailand; the Mon speaking Buddhist civilization of Dvaravati in the first millennium giving way to the Khmer empire of Angkor by the turn of the second millennium.
However, the history of Thailand as we know it began when the kingdoms of Lan Na (Chiang Rai/Chiang Mai) and Sukhothai, the first truly independent Thai Kingdoms, established highly developed societies in the North and Central regions of Thailand in the 13th and 14th centuries. The Kingdom of Ayutthaya, which was heavily influenced by the Khmer’s of Angkor, eventually conquered neighboring Sukhothai and dominated the region for the next several hundred years of Thai history. Unfortunately, first Chaing Mai and then Ayutthaya were overrun by Burmese invaders, who occupied the Lan Na capital for several centuries and sacked Ayutthaya, forcing the central Thai kingdom to relocate farther south, establishing a new capital in Thon Buri near Bangkok. After the short lived Thon Buri Period (1767-1772), the capital was moved across the Chao Phraya River, and the first of the current line of Kings, Rama I of the Chakri Dynasty, established the modern capital of Bangkok to commence the Ratanakosin Period of Thai history. The adroit diplomatic leadership of Kings Mongkut (Rama IV, 1851-1868) and Chulalongkorn (Rama V,1868-1910) were responsible for maintaining a remarkable 700 year Thai history during which the kingdom was never officially colonized by foreign powers; a turbulent 20th century witnessed the transition to a system of constitutional monarchy, currently overseen by Head of State, King Bumibol Adulyadej (1946- present), is King Rama IX of the Chakri Dynasty and a tenuous but functional democracy has existed under the regency of this much beloved king.
Fossilized remains of plants and animals have been discovered in many areas of Thailand, particularly in the Korat Plateau in northeastern Thailand. Most of the animal fossils found are of dinosaurs, which date primarily to the Jurassic era though some are from the late-Triassic, the oldest such evidence of dinosaurs in Southeast Asia.
The dinosaur bones encased in sandstone in the Phu Wiang hills of Khon Kaen province included Phuwiangosaurus sirindhornae, a gigantic plant-eating dinosaur that had a long neck and tail and a small head.
Four other species of dinosaur unearthed in Phu Wiang include Siamotyrannus isanensis, a smaller version of Tyrannosaurus rex, Siamosauraus suteethorni, a crocodile – like creature, Compsognathus, the world’s smallest dinosaur, and Ornithomimosaur, an ostrich-like dinosaur.
Thais began to emerge as a dominant force in the region in the13th century, gradually asserting independence from existing Khmer and Mon kingdoms. Founded by Khun Pha Muang and Khun Bang Klang Thao in 1238, the Kingdom was named by its rulers “the dawn of happiness”. The Sukhothai Period is often considered the golden era of Thai history, an ideal Thai state in a land of plenty governed by paternal and benevolent kings, the most famous of whom was King Ramkamhaeng the Great (c.1279-98), who greatly expanded the Kingdom’s borders.
In addition to developing some of the most beautiful Thai art, the Sukhothai Kingdom is credited with developing the modern Thai alphabet. However, following the death of King Ramkamhaeng, the mightier state of Ayutthaya gradually exerted its influence over Sukhothai.
The Ayutthaya kings adopted Khmer cultural influences from the very beginning. No longer the paternal and accessible rulers that the kings of Sukhothai had been, Ayutthaya’s sovereigns were absolute monarchs and assumed the title devaraja (god-king). The early part of this period saw Ayutthaya extend its sovereignty over neighboring Thai principalities and come into conflict with its neighbors. During the 17th century, Siam started diplomatic and commercial relations with western countries. In 1767, after repeated attempts, the Burmese invaded and successfully captured Ayutthaya.
Despite their overwhelming victory, the Burmese did not retain control of Siam for long. A young general named Phya Taksin and his followers broke through the Burmese lines and escaped to Chantaburi. Seven months after the fall of Ayutthaya, he and his forces sailed back up the Chao Phraya River to Ayutthaya and expelled the Burmese occupation garrison, though tragically the capital had been looted and nearly razed.
General Taksin, as he is popularly known, decided to transfer the capital from Ayutthaya to a site nearer to the sea, a move that would facilitate foreign trade, ensure the procurement of arms, and make defense and withdrawal easier in case of a renewed Burmese attack. He established his new capital at Thon Buri, on the west bank of the Chao Phraya River, opposite modern-day Bangkok. The rule of Taksin was not an easy one. The lack of central authority since the fall of Ayutthaya led to the rapid disintegration of the kingdom, and Taksin’s reign was spent reuniting the provinces.
After Taksin’s death, General Chakri (Rama I) became the first king of the Chakri Dynasty, ruling from 1782 to 1809. His first action as king was to transfer the royal capital across the river from Thon Buri to Bangkok and build the Grand Palace. Rama II (1809 -1824) continued the restoration begun by his predecessor. King Nang Klao, Rama III ( 1824 – 1851 ) reopened relations with Western nations and established trade with China.
King Mongkut, Rama IV, (1851 – 1868) may have achieved western fame through the story “The King and I”, but won the hearts of Thais for his accomplishments including the establishment of treaties with European countries, thus avoiding colonialization, and modernizing Thailand through many social and economic reforms. King Chulalongkorn, Rama V (1869-1910) continued his father’s tradition of reform, abolishing slavery and improving the public welfare and administrative systems.
Educational reforms, including compulsory education, were introduced by King Vajiravudh, Rama VI (1910-1925). During the reign of King Prajadhipok, Rama VII (1925-1935), Thailand changed from an absolute monarchy to a constitutional monarchy. The king abdicated in 1933 and was succeeded by his nephew, King Ananda Mahidol Rama VIII (1935-1946). The country’s name was changed from Siam to Thailand with the advent of a democratic government in 1939. Our current monarch, King Bhumibol Adulyadej (R. Jun. 9, 1946 - present), is King Rama IX of the Chakri Dynasty.
