110-473: Khet Thung Khru is a second-order administrative division. The district was established as Rat Burana. It became Khet Thung Khru in 1998. It was then moved back to Thonburi Province until Thonburi and Bangkok were merged. Thung Khru means 'the plain in the larger area'. "Thung" is a Thai word which means 'flat land' while "khru" has several meanings. It is thought that khru here stands for a kind of utensil woven and coated for water transport, hence an indication that

220-604: A center of trade, fostered by Narai. Of these competing foreign influences, Narai tended to favor relations with the French, wary of the growing Dutch and English colonial possessions in the South China Sea . Soon, Narai began to welcome communities of French Jesuits into his court, and pursue closer relations with both France and the Vatican . Indeed, the many diplomatic missions conducted by Narai to such far-flung lands are some of

330-458: A faction of native Siamese courtiers, Buddhist clergy, and other non-Catholic and/or non-French elements of Narai's court began to resent the favorable treatment French interests received under his reign. This hostile attitude was especially directed at Constantine Phaulkon , a Catholic Greek adventurer and proponent of French influence who had climbed to the rank of Narai's Prime Minister and chief advisor of foreign affairs. Much of this turmoil

440-683: A greatly expanded Siamese kingdom to be ruled by his younger brother, Ekathotsarot (Sanphet III). Ekathotsarot's reign was marked with stability for Siam and its sphere of influence, as well as increased foreign interactions, especially with the Dutch Republic , Portuguese Empire , and Tokugawa Shogunate (by way of the Red Seal Ships ), among others. Indeed, representatives from many foreign lands began to fill Siam's civil and military administration – Japanese traders and mercenaries led by Yamada Nagamasa , for example, had considerable influence with

550-533: A major change from the 13th century during the Sukhothai Kingdom in the 13th and 14th centuries and the Ayutthaya Kingdom that succeeded it when rice growing intensified with the introduction of floating rice , a much faster-growing strain of rice from Bengal . The southern swamps meanwhile changed radically from the 18th century when King Buddha Yodfa Chulaloke moved the capital of Siam to Bangkok, and

660-565: A maritime state to more of a hinterland state during the 15th and 16th centuries. Its absorption of the Northern Cities and the shifting of trade power to the inland trade routes with China facilitated this change of policy. The reign of King Borommatrailokkanat was the peak of this merger between the basin and the Northern Cities , being the scion of generations of intermarriage between the two. Even though Borommatrailokkanat symbolized

770-425: A new city named Sangkaburi (สังขะบุรี) on the south bank of Lopburi River near the present-day Wat Thammikarat Sakorn ruled the city for 97 years until he died in 974 and the throne was then transferred to another royal lineage from Inthapatnakhon (อินทปัตนคร), Phraya Khodhom (พระยาโคดม), who then relocated the city eastward to the right bank of Pasak River near the present Wat Ayodhya  [ th ] , and

880-514: A number of rewards for the number of enemies beheaded. The introduction of elephants, guns, and mercenaries made wars in Southeast Asia much more chronic and much more deadly. By the late 16th century, Pegu (Bago) suffered a severe conscript revolt, Ayutthaya phrai fled into the forests or bribed the conscription officers, and the construction of sturdier and stronger city walls made warfare largely ineffective. The Ayutthaya Kingdom shifted from

990-497: A number of tributary states. Starting in the middle of the 16th century, the kingdom came under repeated attacks by the Taungoo dynasty of Burma . The Burmese–Siamese War (1547–1549) resulted in a failed Burmese siege of Ayutthaya. A second siege (1563–1564) led by King Bayinnaung forced King Maha Chakkraphat to surrender in 1564. The royal family was taken to Pegu (Bago), with the king's second son Mahinthrathirat installed as

1100-486: A peaceful order of succession and the introduction of capitalism undermined the traditional organization of its elite and the old bonds of labor control which formed the military and government organization of the kingdom. In the mid-18th century, the Burmese Konbaung dynasty invaded Ayutthaya in 1759–1760 and 1765–1767 . In April 1767, after a 14-month siege, the city of Ayutthaya fell to besieging Burmese forces and

1210-624: A process of canalisation and cultivation began, especially as Thailand began to export rice from 1855. The Tha Chin River is the major distributary of the Chao Phraya River. The expanse of the Chao Phraya and Tha Chin Rivers and their distributaries, starting at the point at which the distributaries diverge, together with the land amid the triangle formed by the outermost and innermost distributary, form

1320-414: A prolonged period of peace and commerce, beginning with the reign of Ekathotsorot . The Portuguese and Dutch conquest of Malacca encouraged Asian traders to bypass Malacca by crossing the portage route mid-peninsula, controlled by Ayutthaya. This was a period of the great Asian empires: Ottoman Empire , Safavid Empire , Mughal Empire , Ming and Qing China , and Tokugawa Japan. Ayutthaya therefore became

1430-608: A prominent role. Under the reign of Maha Chakkraphat , the Northern lords, led by the Lord of Phitsanulok, Maha Thammarachathirat , became kingmakers in Ayutthaya. The final nail for this transition was the overthrow of the Suphanburi clan from the Ayutthaya throne following the 1569 Burmese capture of Ayutthaya, placing Maha Thammarachathirat on the Ayutthaya throne. The 15th century also marked

1540-521: A relic of the original landscape. As so much has been cleared or altered the potential for creating large protected areas to preserve original habitat no longer exists. However much wildlife does remain in the rice fields and steps may be taken to preserve these as urban and industrial development on the plains is ongoing and the Industrial Estate Authority of Thailand has very little control or planning over this. Particular threats come from

1650-647: A tribute mission to Song dynasty in 1180 and Phetchaburi to the Yuan dynasty in 1294 and tribute missions to Vijaynagar empire between 1400 and 1500 Archaeological findings have found evidence of buildings on the island of Ayutthaya prior to the 12th century. Pottery shards have been discovered to have been dated as early as the 1270s. Some temples to the east of Ayutthaya, off the island, have been known to exist before 1351. Recent archaeological works reveal pre-existing barays superimposed on by subsequent structures. The Tamnan mulasasana Buddhist chronicle notes that in

1760-445: A turning point in Ayutthaya's view of itself. King Borommatrailokkanat performed some sort of coronation ceremony, the first in Ayutthaya history, in the 1460s. Prior to the 15th century, Ayutthaya's palaces and temples were inferior in grandeur to cities such as Sukhothai and Phitsanulok. By the early 16th century, Ayutthaya had now rivalled its regional competitors in its city grandeur, building magnificent wats and palaces for kings with

1870-710: Is observed annually on 18 January as Royal Thai Armed Forces day. Later that same year warfare erupted again (the Burmese–Siamese War (1593–1600) ) when the Siamese invaded Burma, first occupying the Tanintharyi province in southeast Burma in 1593 and later the cities of Moulmein and Martaban in 1594. In 1599, the Siamese attacked the city of Pegu but were ultimately driven out by Burmese rebels who had assassinated Burmese King Nanda Bayin and taken power. In 1613, after King Anaukpetlun reunited Burma and took control,

1980-717: Is also mentioned in the Burmese chronicle, Hmannan Yazawin , which mentions the Gywan warriors marched to Thaton kingdom in 1056 AD as inscribed on the Burmese inscriptions at Arakan Pagoda, Mandalay . The Hmannan Yazawin said the south-eastward country of the Gywans, also called Ayoja . George Cœdès pointed out that Ayoja or Arawsa meant Ayudhya = Siam. In 877, a royal lineage from Bang Pan (present-day in Phran Kratai , Kamphaeng Phet ), Phra Maha Buddha Sakorn (พระมหาพุทธสาคร), founded

2090-487: Is at a single location that covers less than 10 km (4 sq mi). The endangered dwarf loach , another species bred in large numbers for the aquarium trade, has been extirpated from most of its range in Chao Phraya. The critically endangered Siamese tigerfish has been entirely exirpated from Chao Phraya and Mae Klong, but small populations remain in the Mekong basin. Many other species that either are prominent in

2200-590: The Ayutthaya period. Several shortcut canals were constructed to bypass large loops in the river, shortening the trip from the capital city to the sea. The course of the river has since changed to follow many of these canals. Provinces along the Chao Phraya include, from north to south, Nakhon Sawan Province , Uthai Thani Province , Chai Nat Province , Sing Buri Province , Ang Thong Province , Ayutthaya Province , Pathum Thani Province , Nonthaburi Province , Bangkok , and Samut Prakan Province . These cities are among

2310-727: The Gulf of Thailand . On many old European maps, the river is named the Mae Nam (แม่น้ำ), the Thai word for "river" (literally, "motherly water"). Irish surveyor and cartographer James McCarthy , F.R.G.S. , who served as Director-General of the Siamese Government Surveys prior to establishment of the Royal Thai Survey Department , wrote in his account, " Mae Nam is a generic term, mae signifying "mother" and Nam "water," and

2420-500: The IUCN ), but Cryptophaea saukra is critically endangered and Caliphaea angka is endangered . There are few areas of wetland protected as national parks, but these are mostly very small. The Chao Phraya basin is home to around 280 species of fish, including about 30 endemics . By far the most diverse family is Cyprinidae with 108 species. The mainstream of the Chao Phraya River has about 190 native fish species. In general,

2530-573: The Ping River (with its principal confluent, the Wang River ), and the Tha Chin River . Each of these tributaries (and the Chao Phraya itself) is augmented by minor tributaries referred to as khwae . All of the tributaries, including the lesser khwae, form an extensive tree-like pattern, with branches flowing through nearly every province in central and northern Thailand . None of the tributaries of

Additionally, Songtham maintained the service of Yamada Nagamasa, whose Japanese mercenaries were at this point serving as the king's own royal guard . As Songtham's life began to fade,

2750-463: The Suphannabhum dynasty based on Suphanburi. Traditional narratives argued that Ayutthaya conquered Sukhothai, Angkor , etc., but more modern narratives argue that territorial conquest was a European thing and not a Southeast Asian thing. Rather, the processes which saw Ayutthaya expand was one of political merger and consolidation between the cities at the head of the peninsula and slowly ascending up

2860-626: The capture of Malacca by the Portuguese. Ayutthaya's attention to the portage routes across the upper peninsula meant that it did not send a military expedition to the lower peninsula and the Malay States throughout the 16th century. Ayutthaya's sphere of influence was now stretched from the Northern Cities to the Malay Peninsula, with its heartland centered around the old Ayutthaya-Suphanburi-Lopburi-Phetchaburi polity. The Muang Look Luang system

2970-682: The confluence of the Ping and Nan rivers at Nakhon Sawan (also called Pak Nam Pho) in Nakhon Sawan province . After this, it flows south for 372 kilometres (231 mi) from the central plains to Bangkok and the Gulf of Thailand . In Chai Nat , the river then splits into the main course and the Tha Chin River , which then flows parallel to the main river and exits in the Gulf of Thailand about 35 kilometres (22 mi) west of Bangkok in Samut Sakhon . In

3080-463: The water quality of major rivers flowing into the upper Gulf of Thailand has seriously deteriorated, and the lower Chao Phraya contains bacteria and nutrient pollution from phosphates , phosphorus , and nitrogen . Nutrient pollution causes algae to grow faster than ecosystems can handle, harming water quality, food resources for aquatic animals, and marine habitats. It also decreases the oxygen that fish need to survive. PCD rated water quality at

3190-460: The 11th century or at least several centuries prior to 1351. The earliest written records of Ayutthaya in the Chinese chronicles is that a Chinese official fled to Xian in 1282/83. Xian first sent an embassy to China in 1292, who the Chinese then requested another embassy soon after that, signifying Ayutthaya's early prominence before Ayutthaya's founding. While older and traditional scholars argue that

3300-484: The 1320s, two Buddhist monks visited Ayutthaya in search of scriptures and that a previous monk had been honored by the "King of Ayodhia" on his return from Lanka . Since the late 13th century, expeditions were sent to the Malay Peninsula and Sumatra in the goal of extracting resources to gain a share of the maritime trade. Other contemporary scholars argued that Ayutthaya had been an important commercial center since

3410-420: The 1760s , whose post-Ayutthaya monarchs ( Taksin and Rama I ), held close ties, through blood and through political connections, to this Sino-Siamese community. Between 1600 and 1767, all but two royal successions were contested in a mini civil war in the capital. The throne became such a powerful and lucrative source of wealth during the 150 years of prosperity that many royals harbored ambitions to seize

3520-625: The Burmese in 1767, stating: Clearly, however, the late 1600s and especially the early 1700s inaugurated a period not of sustained decline, but of Chinese-assisted economic vitality that would continue into the 19th century. Instead, the 18th century was arguably the Ayutthaya Kingdom's most prosperous, particularly due to trade with Qing China . The growth of China's population in the late 17th–18th centuries, alongside nationwide rice shortages and famines in Southern China, meant that China

3630-559: The Burmese invaded the Siamese-held territories in Tanintharyi province, and took Tavoy. In 1614, the Burmese invaded Lan Na which at that time was a vassal of Ayutthaya. Fighting between the Burmese and Siamese continued until 1618 when a treaty ended the conflict. At that time, Burma had gained control of Lan Na and while Ayutthaya retained control of southern Tanintharyi (south of Tavoy). The cessation of warfare around 1600 gave way to

3740-571: The Chao Phraya delta . The many distributaries of the Chao Phraya delta are interconnected by canals that serve both for irrigation and for transportation. The lowland areas of the Chao Phraya watershed in central Thailand have been designated as the Chao Phraya freshwater swamp forests , a tropical and subtropical moist broadleaf forests ecoregion , an area about 400 km (249 mi) north to south and 180 km (112 mi) wide. The original swamp forests have almost entirely been removed as

3850-490: The Chao Phraya River Basin to the Northern Cities. The culture of early Ayutthaya, described by Ma Huan , a scribe on Zheng He's voyages , in the early 15th century, described Ayutthaya as a rowdy port town, whose men practice fighting on water, and where the affairs of everyday life was arranged by the women. The cities on the peninsula regularly complained to the Chinese court about constant Siamese attacks down

3960-709: The Chao Phraya extend beyond the nation's borders. The Nan and the Yom River flow nearly parallel from Phitsanulok to Chumsaeng in the north of Nakhon Sawan Province. The Wang River enters the Ping River near Sam Ngao district in Tak Province . When measured from the most commonly accepted source, which is the confluence of the Ping and Nan River in Nakhon Sawan, the river measures 372 km (231 mi). However, when measured from

4070-615: The Chao Phraya is a major transportation artery for a network of river buses, cross-river ferries, and water taxis ("longtails"). More than 15 boat lines operate on the rivers and canals of the city, including commuter lines . The principal tributaries of the Chao Phraya River are the Pa Sak River , the Sakae Krang River , the Nan River (along with its principal confluent the Yom River ),

4180-425: The Chinese court chronicles. The integrity of the patchwork of cities of early Ayutthaya Kingdom was maintained largely through familial connections under the mandala system . King Uthong had his son, Prince Ramesuan , the ruler of Lopburi (Lavo), his brother, the ruler of Praek Sriracha (in modern Chainat Province ) and his brother-in-law, Khun Luang Pa-ngua , the ruler of Suphanburi. The ruler of Phetchaburi

4290-541: The Dutch. Despite the departure of most Europeans from Ayutthaya, their economic presence in Ayutthaya was negligible in comparison to the Ayutthaya China-Indian Ocean trade. Lieberman, later reinforced by Baker and Phongpaichit, refutes the idea that Siam's alleged isolationism from global trade following the French and English departure in 1688 led to Ayutthaya's gradual decline leading up to its destruction by

4400-417: The French court of King Louis XIV . The Late Ayutthaya Period saw the departure of the French and English but growing prominence of the Chinese. The period was described as a "golden age" of Siamese culture and saw the rise in Chinese trade and the introduction of capitalism into Siam, a development that would continue to expand in the centuries following the fall of Ayutthaya. Ayutthaya's failure to create

4510-488: The Lower Chao Phraya Valley in the late 13th and 14th centuries ( Lopburi , Suphanburi , and Ayutthaya). The early kingdom was a maritime confederation, oriented to post- Srivijaya Maritime Southeast Asia, conducting raids and tribute from these maritime states. After two centuries of political organization from the Northern Cities and a transition to a hinterland state, Ayutthaya centralized and became one of

The lower Chao Phraya Basin was also influenced by Angkorian culture but not direct Angkorian political and military influence. Ayutthaya, argued by Charnvit Kasetsiri , was the merger of four different port polities along the Lower Chao Phraya Basin: Lopburi (Lavo), Suphanburi, Ayutthaya, and Phetchaburi. Suphanburi had first sent

4730-472: The Northern Cities. Muslim and European mapmakers labelled the Malay Peninsula up to the Tenasserim coast as part of Ayutthaya in the 15th and early 16th centuries. Early Ayutthaya did not keep records and their early dynastic chronology is likely fabricated by later Ayutthaya elites writing their histories: the early chronology in the palace chronicles does not correlate with the Ayutthaya temple chronicles nor

4840-583: The anti-foreign court faction were primarily concerned with Catholic influence, there is evidence to suggest that Narai was equally interested in Islam, and had no desire to fully convert to either religion. Nonetheless, a dissatisfied faction now led by Narai's celebrated elephantry commander, Phetracha , had long planned a coup to remove Narai. When the king became seriously ill in May 1688, Phetracha and his accomplices had him arrested along with Phaulkon and many members of

The Thai Pollution Control Department (PCD) reports that

5060-615: The aquatic fauna of Chao Phraya and Mae Klong show clear similarities, and they are sometimes combined in a single ecoregion with 328 fish species. Despite their similarities, there are also differences between the aquatic fauna of Chao Phraya and Mae Klong; the latter (but not the former) is home to a few taxa otherwise only known in major Burmese rivers: the Irrawaddy , Salween , and Tenasserim . The aquatic fauna in Chao Phraya–Mae Klong also show clear similarities with that of

5170-526: The area was once famous for the handicraft. Thung Khru has two sub-districts ( khwaeng ), Bang Mot and Thung Khru. Although Buddhist temples in Thung Khru are not remarkable, with the possible exceptions of Wat Thung Khru, Wat Phutthabucha and Wat Bang Mot. Places of worship representing other religions are well represented. Neighboring districts are (from the west clockwise) Thung Khru, Rat Burana, Yan Nawa, Khlong Toei, Phra Khanong, and Bang Na (all Bangkok), and

5280-526: The border between the two adversaries continued for two years and at one time Narai seized Tavoy and Martaban. Ultimately, Narai and the Siamese ran out of supplies and returned home back within their border. While commercially thriving, Narai's reign was also socially tumultuous. Much of this can be attributed to three-way conflict between the Dutch , French , and English trading companies now operating in Siam at an unprecedented intensity due to Siam's role as

5390-401: The capital to press their claims, culminating in several bloody coups. With the dominance of the Suphanburi clan, it now had to face the militaristic nobles of the Northern Cities, who increasingly came south for wealth prospects at an increasingly wealthy and powerful Ayutthaya. The first real succession struggles in Ayutthaya occurred in the early 16th century, with the Northern lords playing

5500-444: The city of Ayutthaya , in Siam, or present-day Thailand . European travellers in the early 16th century called Ayutthaya one of the three great powers of Asia (alongside Vijayanagara and China). The Ayutthaya Kingdom is considered to be the precursor of modern Thailand, and its developments are an important part of the history of Thailand . The Ayutthaya Kingdom emerged from the mandala or merger of three maritime city-states on

5610-419: The conversion of rice paddies to large-scale production of prawns by pumping in seawater, and the use of pesticides to eliminate the introduced snail, Pomacea canaliculata , which damages rice plants. There are populations of threatened birds, including colonies of breeding water birds such as the world's largest populations of the near-threatened Asian openbill ( Anastomus oscitans ), and other birds such as

Under the Samuha Nayok were the Four Ministries. In the regions, the king sent not "rulers" but "governors" to govern cities. The cities were under governors who were from nobility not rulers with privileges as it had previously been. The "Hierarchy of Cities"

The critically endangered red-tailed black shark , a small colourful cyprinid that is endemic to Chao Phraya, is commonly seen in the aquarium trade where it is bred in large numbers, but the only remaining wild population

5940-446: The crown. The ability to appoint a Front Palace was effective in times of war but became a double-edged sword in regards to peace. Foreigners, due to their lack of connections within the kingdom, often became prominent officials within the Ayutthaya court during this period. In 1605, Naresuan died of illness while on campaign against a Burmese spillover conflict in the Shan region, leaving

The district is divided into two sub-districts ( khwaeng ). Chao Phraya River The Chao Phraya River is the major river in Thailand , with its low alluvial plain forming the centre of the country. It flows through Bangkok and then into

6160-473: The divide roughly corresponds to a long section of the political border of the country today. Southern portions of the divide's boundary correspond less to the nation's political border, because isolation in this area was prevented by the ease of transportation along the lowlands surrounding the Gulf of Thailand, allowing a unified Thai civilisation to extend beyond the watershed without issue. The slightly higher northern plains have been farmed for centuries and saw

Herbert Warington Smyth , who served as Director of the Department of Mines in Siam from 1891 to 1896, refers to it in his book first published in 1898 as "the Mae Nam Chao Phraya". In the English-language media in Thailand, the name Chao Phraya River is often translated as river of kings . On the basins of Chao Phraya River rose

Michael Vickery argued that it is likely the Chinese used Xian to refer to the lower Chao Phraya Basin from its inception. Recent 21st-century archaeological surveys have found that

6600-480: The fish species known from the Chao Phraya–Mae Klong, only about 50 are absent from the Mekong. There has been extensive habitat destruction (pollution, dams , and drainage for irrigation ) in the Chao Phraya basin and overfishing also presents a problem. Within mainland Southeast Asia , the only freshwater region with similar high levels of threat is the lower Mekong. It has been estimated that only around 30 native fish species still are able to reproduce in

In the seventeenth and eighteenth centuries, Ayutthaya emerged as an entrepôt of international trade and its cultures flourished. The reign of Narai ( r. 1657–1688) was known for Persian and later, European, influence and the sending of the 1686 Siamese embassy to

Thus, Prasat Thong had completely usurped the kingdom by double (perhaps triple) regicide, extinguishing the Sukhothai dynasty 60 years after its installation by the Burmese. Many of King Prasat Thong's former allies abandoned his cause following his ascension to the throne. In the course of quelling such resistance, Prasat Thong assassinated his former ally Yamada Nagamasa in 1630 (who now opposed Prasat Thong's coup), and promptly banished all

6930-664: The issue of succession generated conflict once again when both King Songtham's brother, Prince Sisin, and his son, Prince Chetthathirat , found support for their claims among the Siamese court. Although Thai tradition typically favored brothers over sons in matters of inheritance, Songtham enlisted the help of his influential cousin, Prasat Thong to ensure his son would inherit the kingdom instead. When Songtham died in 1628, Prasat Thong used his alliance with Yamada Nagamasa's mercenaries to purge everyone who had supported Prince Sisin's claim, eventually capturing and executing Sisin as well. Soon Prasat Thong became more powerful in Siam than

7040-424: The king. Ekathotsarot's era ended with his death in 1610/11. The question of his succession was complicated by the alleged suicide of his eldest legitimate son, Suthat, while his second legitimate son, Si Saowaphak , was never legally designated as an heir by Ekathotsarot himself. Nonetheless, Si Saowaphak succeeded to the throne against his late father's wishes, and led a short and ineffective reign in which he

7150-409: The late 15th century. Song China's increasing interests to sea commerce at the turn of the second millennium made trade between China and the Indian Ocean especially lucrative. In the 1430s, Ayutthaya attacked Angkor , but did not sack the city, although Ayutthaya did install a short-lived puppet ruler. Palace Law Codes under Borommatrailokkanat exemplified the newfound attention to warfare, citing

7260-456: The longest source, which is the origin point of the Nan River in the Luang Prabang Range , the river measures 1,112 km (691 mi). The expanse of the Chao Phraya River and its tributaries, i.e., the Chao Phraya river system, together with the land upon which falling rain drains into these bodies of water, form the Chao Phraya watershed . The Chao Phraya watershed is the largest watershed in Thailand, covering approximately 35 percent of

The khlongs are used for the irrigation of the region's rice paddies. The rough coordinates of the river are 13 N, 100 E. This area has a wet monsoon climate, with over 1,400 millimetres (55 in) of rainfall per year. Temperatures range from 24 to 33 °C (75 to 91 °F) in Bangkok. The lower Chao Phraya underwent several human-made modifications during

7480-442: The lucrative middleman for trade between the global empires of the Early Modern World. Kings and nobles turned to hunting, trade, and the competition for the throne with the ending of warfare. This period of Ayutthaya is also characterized by the emergence of mercantile absolutism, where the king had a virtual monopoly on all incomes into the kingdom, allowing the king to build new temples and palaces, sponsor ceremonies, and enshroud

Recent records of the near-endemic cyprinid Balantiocheilos ambusticauda are also lacking and it is possibly extinct. Three of the largest freshwater fish in the world are native to the river, but these are all seriously threatened:

7700-580: The merger between North and South, the Lan Na Kingdom , a state North of Ayutthaya (modern-day Northern Thailand ), contested Ayutthaya's growing influence over the Northern Cities. The Ayutthaya-Lan Na War was fought over the Upper Chao Phraya valley for control of the Northern Cities. Whether he preferred the Northern Cities to Ayutthaya or the necessity to have a capital closer to the war, Borommatrailokkanat moved his capital to Phitsanulok . Lan Na suffered setbacks and Borommatrailokkanat eventually sued for peace in 1475. Ayutthaya's sphere of influence down

7810-491: The middle Mekong (the lower Mekong fauna more closely resembles that of the eastern Malay Peninsula ). It is believed that the upper Mekong was connected to Chao Phraya (rather than present-day lower Mekong) until the Quaternary , which explains the similarities in their river faunas. This included the Nan River basin, a tributary of the Chao Phraya, which is home to a number of taxa (for example, Ambastaia nigrolineata and Sectoria ) otherwise only known from Mekong. Of

7920-402: The monarchy in ritual mysticism. The king had the power to appoint governors of cities in the inner Ayutthaya mueang (cities) as well as appoint ministers in charge of the government. This however all made the target of the throne much more lucrative and rewarding than before. To be able to successfully put your target onto the throne would immensely reward its facilitators as much as the winner of

8030-646: The most celebrated accomplishments of his reign. Narai as well leased the ports of Bangkok and Mergui to the French, and had many French generals incorporated into his army to train it in Western strategy and supervise the construction of European-style forts. During this time, Narai abandoned the traditional capital of Ayutthaya for a new Jesuit-designed palace in Lopburi . As a growing Catholic presence cemented itself in Siam, and an unprecedented number of French forts were erected and garrisoned on land leased by Narai,

8140-627: The most historically significant and densely populated settlements of Thailand due to their access to the waterway. Major bridges cross the Chao Phraya in Bangkok: the Rama VI railroad bridge; Phra Pin-klao near the Grand Palace ; Rama VIII , a single tower asymmetrical cable-stayed bridge; Rama IX , a semi-symmetric cable-stayed bridge; and Mega Bridge , on the Industrial Ring Road. In Bangkok,

8250-513: The mouth of Chao Phraya at Bangkok's Bang Khun Thian District as "very poor", worse than in 2014, and their findings indicated large amounts of wastewater were discharged into the river from households, industry, and agriculture. In addition, 4,000 metric tons of plastic flows down the river into the Gulf of Thailand every year. To counter this, Thailand's Department of Marine and Coastal Resources (DMCR) signed an agreement with The Ocean Cleanup organization to deploy an Interceptor Original, one of

8360-554: The much-hunted Schomburgk's deer . Today we can only guess at the original habitat and wildlife by comparing it with neighbouring countries. It is believed that the area would have consisted of freshwater swamps inland and salty mangroves on the coast and the river estuaries. The swamp would have been covered in Phragmites marsh grasses. Today there is a small area of this remaining in Khao Sam Roi Yot National Park ,

8470-512: The name of pre-Ayutthaya cities is Ayodhaya Sriramthep Nakorn ( Thai : อโยธยาศรีรามเทพนคร ) found on Wat Khao Kop Inscription (N.W. 2, Face 2, Line 21) aged 14th–15th centuries, as stated in the Thai Chronicle, Phraratchaphongsawadan Nuea (Royal Chronicle of The North compiled in 1807 collected from old books from period of King Narai and stories told by northerners). At least three royal decrees in Thai were enacted during that period, and

8580-528: The name of the king who ruled Ayodhaya in the oldest of the three royal decrees, the Miscellaneous Laws (Phra Aiyakan Betset) 1225 AD , is found as King Uthong, who reigned from 1205 to 53 (not to be confused with King Uthong reigning from 1351 to 69). It was also found that Thai was used as the official language at that time, which reflected the social changes of the people in the Chao Phraya River Basin. The existence of Ayodhya Sri Rama Thep Nakhon

8690-611: The nation's land, and draining an area of 157,924 square kilometres (60,975 sq mi). The watershed is divided into the following basins: To the west, the central plain of Thailand is drained by the Mae Klong and the east by the Bang Pakong River . They are not part of the Chao Praya system. The landscape of the river basins is a very wide, flat, well-watered plain continuously refreshed with soil and sediment brought down by

8800-491: The newly crowned King Chetthathriat, and through further intrigue staged a coup in which Chetthathirat was deposed and executed in favor of his even younger brother Athittayawong , whom Prasat Thong intended to use as a puppet ruler. This form of government was quickly met with resistance by elements within the Thai court who were dissatisfied with the idea of having two acting heads of state. Since Prasat Thong already ruled Siam in all but name as Kalahom , he opted to resolve

8910-421: The old city Sangkaburi was abandoned. Khodhom ruled the new city for 30 years then his son, Kothrabong (โคตรบอง), took over the throne in 1004. Later in 1022, Kothrabong lost power to Kreak (แกรก), a commoner from Lavo , who was then crowned as the new ruler named Sinthapomarin (สินธพอมรินทร์). Because Kreak was not originally considered a royal lineage, after he died in 1081, the throne was despoiled by Narai,

9020-509: The only thing known about Uthong in the chronicles is the year of his death. In the 1290s through to the 1490s, Ayutthaya sent forces down to the peninsula and demanded tribute from the Malay principalities all the way down to Temasek ( Singapura (modern Singapore)) and Sumatra . The early Ayutthaya polity was a maritime-oriented confederation, more in line with the Malay polities of Maritime Southeast Asia than with states inland like Sukhothai and

9130-597: The organization's solar-powered, automated systems, in the river. Since 19 February 2024, an interceptor of the latest third generation has been deployed for testing purposes. 13°32′25″N 100°35′23″E  /  13.54028°N 100.58972°E  / 13.54028; 100.58972 Ayutthaya Kingdom The Ayutthaya Kingdom or the Empire of Ayutthaya was a Mon and later Siamese kingdom that existed in Southeast Asia from 1351 to 1767, centered around

9240-433: The peninsula around this time period. The 1430s through to 1600 marked a period of rising warfare throughout Mainland Southeast Asia. In 1500, the Portuguese noted that Ayutthaya had 100 elephants, 50 years later, Ayutthaya had 50,000 elephants. Ayutthaya began launching military land expeditions far to the west and east. In the west, Ayutthaya fought to acquire the cities of Tavoy , Mergui , Tenasserim, and Martaban in

9350-592: The peninsula was contested by the Malacca Sultanate . Ayutthaya launched several abortive conquests against Malacca which was diplomatically and economically fortified by the military support of Ming China . In the early-15th century the Ming admiral Zheng He established a base of operation in the port city, making it a strategic position the Chinese could not afford to lose to the Siamese. Under this protection, Malacca flourished, becoming one of Ayutthaya's great foes until

9460-511: The plain has been converted to rice paddies, other agriculture, and urban areas like Bangkok. Much of the wildlife that once inhabited these plains has disappeared, including a large number of fish in the river systems, birds such as vultures, the Oriental darter ( Anhinga melanogaster ), white-eyed river martin ( Pseudochelidon sirintarae ), the sarus crane ( Grus antigone ) and animals such as tigers , Asian elephants , Javan rhinoceroses , and

9570-496: The remaining Japanese from Siam. While a community of Japanese exiles were eventually welcomed back into the country, this event marks the end of the Tokugawa Shogunate's long-standing formal relationship with the Ayutthaya Kingdom. Upon his death in 1656, King Prasat Thong was succeeded first by his eldest son, Chai , who was almost immediately deposed and executed by the late King's brother, Si Suthammaracha , who in turn

9680-494: The rivers. The lower central plain from the delta north to Ang Thong Province is a flat, low area with an average of two metres above sea level. Further north and into the plains of the Ping and the Nan the elevation is over 20 m. Then the mountains that are the natural boundary of the Chao Praya watershed form a divide , which has, to some degree, historically isolated Thailand from other Southeast Asian civilisations. In northern Thailand

9790-504: The royal family, all of whom were put to death besides Narai, who died in captivity in July of that year. With the king and his heirs out of the way, Phetracha then usurped the throne and officially crowned himself King of Ayutthaya on 1 August. King Phetracha took Mergui back from French control almost immediately, and began the pivotal Siege of Bangkok , which culminated in an official French retreat from Siam. Phetracha's reign, however,

9900-456: The son of King Chadachota from Lavo Kingdom, who was of the lineage of the previous Sangkaburi's kings. Narai renamed the city Ayodhya (อโยธยา) and eventually set it as the new capital of the Lavo Kingdom during his reign. The former capital was then renamed Lopburi . After the end of Narai's reign in 1147, Ayodhya fell under the power struggles between nine amatyas for two years, until

10010-491: The son of Sanphet I, proclaimed Ayutthaya's independence. This proclamation resulted in repeated invasions of Ayutthaya by Burma which the Siamese fought off ultimately finishing in an elephant duel between King Naresuan and Burmese heir-apparent Mingyi Swa in 1593 during the fourth siege of Ayutthaya in which Naresuan famously slew Mingyi Swa, although the existence of this battle has been challenged by modern scholars such as Sulak Sivaraksa . Today, this Siamese victory

10120-503: The throne was given to Phra Chao Luang (พระเจ้าหลวง), who relocated the city, in 1157, southward to the east bank of the Chao Phraya River near the mouth of the Mae Bea River (แม่น้ำแม่เบี้ย), south of the present Wat Phanan Choeng . The new city was later named Sena Ratchanakhon (เสนาราชนคร) by his successor, Duangkrien Kritnarat (ดวงเกรียนกฤษณราช) or Sai Nam Peung who was appointed the new ruler by his father, Kraisornrat (ไกรสรราช) who

10230-520: The throne. An Ayutthaya noble in the 18th century lamented that a large portion of court officials and able generals were killed in multiple succession struggles over the past 90 years. The last monarch, Ekkathat , alongside his brother, Uthumphon , undermined Prince Thammathibet , the Front Palace Uparaj and designated heir to his father, King Borommakot , by instigating or exposing his affair with two of his fathers' consorts. Prince Thammathibet

10340-450: The vassal king. In 1568, Mahinthrathirat revolted when his father managed to return from Pegu as a Buddhist monk . The ensuing third siege captured Ayutthaya in 1569 and Bayinnaung made Maha Thammarachathirat (also known as Sanphet I) his vassal king, instating the Sukhothai dynasty . In May 1584, less than three years after Bayinnaung's death, Uparaja Naresuan (or Sanphet II),

10450-440: The wintering black kite ( Milvus migrans ). Endemic mammals that remain are the limestone rat ( Niviventer hinpoon ), Neill's long-tailed giant rat ( Leopoldamys neilli ), and the near-endemic Thailand roundleaf bat ( Hipposideros halophyllus ). The Chao Phraya basin is home to about half a dozen endemic dragonflies and damselflies . The conservation status of most of these in unclear (they are rated as data deficient by

10560-465: Was also referred to as Iudea in a painting requested by the Dutch East India Company . The capital city of Ayutthaya is officially known as Krung Thep Dvaravati Si Ayutthaya ( Thai : กรุงเทพทวารวดีศรีอยุธยา ), as documented in historical sources. The lower Chao Phraya Basin around the turn of the second millennium was split between Lavo Kingdom , which dominated the eastern half of

10670-504: Was also the Lopburi's king. The city of Ayodhya was abandoned in 1211. After Lopburi 's King Kraisornrat died with no heir apparent, the king of Phraek Siracha (present-day Sankhaburi ), who was the grandfather of Ayutthaya's first king, Uthong , took over the throne. After he died in 1319, both Lopburi and the city of Sena Ratchanakhon was considered royal inheritances for his daughter, who later passed it to her son, Uthong. Ayutthaya

10780-416: Was completely destroyed, thereby ending the 417-year-old Ayutthaya Kingdom. Siam, however, quickly recovered from the collapse and the seat of Siamese authority was moved to Thonburi - Bangkok within the next 15 years. In foreign accounts, Ayutthaya was called "Siam", but people of Ayutthaya called themselves Tai , and their kingdom Krung Tai ( Thai : กรุงไท ) meaning 'Tai country' ( กรุง ไท ). It

10890-414: Was defeated in single combat by his own nephew, Narai . Narai finally assumed a stable position as King of Ayutthaya with the support of a mainly foreign court faction consisting of groups that had been marginalized during the reign of his father, Prasat Thong. Among his benefactors were, notably, Persian, Dutch, and Japanese mercenaries. It should therefore come as no surprise that the era of King Narai

11000-533: Was eager to import rice from other nations, particularly from Ayutthaya. During the Late Ayutthaya Period (1688–1767), the Chinese population in Ayutthaya possibly tripled in size to 30,000 from 1680 to 1767. The Chinese played a pivotal role in stimulating Ayutthaya's economy in the last 100 years of the kingdom's existence and eventually played a pivotal role in Siam's quick recovery from the Burmese invasions of

11110-453: Was established and cities were organized into four levels. Large, top level cities held authorities over secondary or low-level cities. The increased wealth of Ayutthaya resulted in the beginnings of a chronic succession struggle for the Ayutthaya throne. Due to the lack of stable succession law , from each succession from the 16th century onwards, princely governors or powerful dignitaries claiming their merit gathered their forces and moved on

11220-422: Was executed for his alleged crimes. Corruption was rampant due to economic prosperity. Position buying and bribery for political offices became commonplace. The mass arrival of Chinese farming settlers to Siam in 18th century introduced Capitalism to Siam. The past 150 years of growth encouraged phrai to flee the bonds of government control and become peasant farmers in the countryside to earn wealth. People fled

11330-535: Was his distant relative. The king would appoint a prince or a relative to be the ruler of a city, and a city that was ruled by a prince was called Muang Look Luang ( Thai : เมืองลูกหลวง ). Each city ruler swore allegiance and loyalty to the King of Ayutthaya but also retained certain privileges. Politics of Early Ayutthaya was characterized by rivalries between the two dynasties; the Uthong dynasty based on Lopburi (Lavo) and

11440-580: Was inadequate to govern relatively vast territories. The government of Ayutthaya was centralized and institutionalized under King Borommatrailokkanat in his reforms promulgating in Palatine Law of 1455, which became the constitution of Ayutthaya for the rest of its existence and continued to be the constitution of Siam until 1892, albeit in altered forms. The central government was dominated by the Chatusadom system ( Thai : จตุสดมภ์ lit. "Four Pillars), in which

11550-464: Was kidnapped and held hostage by Japanese merchants, and later murdered. After this episode, the kingdom was handed to Songtham , a lesser son born of Ekathotsarot and a first-class concubine. Songtham temporarily restored stability to Ayutthaya and focused inward on religious construction projects, most notably a great temple at Wat Phra Phutthabat . In the sphere of foreign policy, Songtham lost suzerainty of Lan Na, Cambodia and Tavoy, expelled

11660-478: Was later incorporated into the Ayutthaya Kingdom in the 14th century, which itself was precursor of modern Thailand (known formerly as Siam), the river became very significant after the establishment of Rattanakosin (Bangkok) in 1782 on its east bank, the location of Bangkok on the east bank of Chao Phraya River ensured protection to Siamese kingdom from the Burmese invasions coming from the West. The Chao Phraya begins at

11770-452: Was not stable. Many of Phetracha's provincial governors refused to recognize his rule as legitimate, and rebellions by the late Narai's supporters persisted for many years. The most important change to Siam in the aftermath of the revolution was Phetracha's refusal to continue Narai's foreign embassies. King Phetracha opted instead to reverse much of Narai's decisions and closed Thailand to almost all forms of European interaction except with

11880-518: Was one of an extroverted Siam. Foreign trade brought Ayutthaya not only luxury items but also new arms and weapons. In the mid–17th century, during King Narai 's reign, Ayutthaya became very prosperous. In 1662 war between Burma and Ayutthaya (the Burmese-Siamese War (1662-64) ) erupted again when King Narai attempted to take advantage of unrest in Burma to seize control of Lan Na. Fighting along

11990-457: Was primarily religious, as the French Jesuits were openly attempting to convert Narai and the royal family to Catholicism . Narai was courted not just by Catholic conversion, but as well by proselytizing Muslim Persians, Chams and Makassars in his court, the later of which communities launched an unsuccessful revolt in 1686 to replace Narai with a Muslim puppet king. While members of

12100-421: Was traditionally founded by King Uthong on 4 March 1351. This fact, however, has been subject to long scholarly debate. According to Chris Baker-Pasuk Phongpaichit, there are at least seven legends about who Uthong was: "a Northern Thai prince, a fugitive Chinese prince from the sea, a Khmer noble from Angkor, a ruler from one of the gulf cities, or a Chola ." Other than being the legendary founder of Ayutthaya,
