The essence of Chenla is found in the Tonle Sap area, where the Angkor Dynasty once built a powerful and prosperous civilization. Rice is abundant in the Tonle Sap area, which is the core of Chenla's population. The Tonle Sap Lake is connected to the Mekong River by the Tonle Sap River, which in the rainy season flows into the lake, and during the dry season, the Tonle Sap Lake replenishes water to the Mekong River through the Tonle Sap River, which acts as a large natural reservoir that regulates the amount of water in the Mekong River.

Through the mouth of the Mekong River and the small port of the Gulf of Siam, Chenla became a maritime nation in the 16th century. Chenla's political center was originally in the northern part of Lake Tonle Sap, but after the Siamese burned down Lowe, the Chenla people were forced to move south of Lake Tonle Sap. Not far from the mouth of the Tonle Sap River where it joins the Mekong River, the lower reaches of the Mekong River are also divided into the Front River and the Back River, and the four estuaries converge together, which the locals call the Four Forks. During the rainy season, the water of the Mekong River rises, and the warships can go directly up to the four forks. Now a new city is rising at the fork in the road, and this city is called Phnom Penh.

The preparations for the attack on Zhenla went even more smoothly than Shou Xian had imagined. When Kaneshiro made its final public mobilization, Batavia sent 5 warships to Kaneshiro, and the Dutch were to participate in this attack on Chenla. Shou Zhi felt that the Dutch were involved, and put the final nail in the coffin board of Zhenla.

Zhenla has been in civil strife for many years, and the princes of the country have competed for the throne. At the end of the last century, Siam sacked the city of Lowe, the capital of the kingdom of Chenla, and when they evacuated, they set up a puppet king, Soriobo. Son, Solyobo. When Dzheta II ascended the throne, he restored court etiquette and dress from Siamese to Khmer tradition, much to the displeasure of Siam. In order to escape the Siamese invasion, Zheta II moved the capital from Lowe to Udong, further south. In 1623, Siam launched a retaliatory invasion of Chenla, and Zheta II married the daughter of the Nguyen lord of Quang Nam, and with the support of the Hue court, he repelled the Siamese invasion by land and sea. Through this support, Quang Nam also obtained the right to trade and tax along the Saigon River in Pogo Province, and obtained a fulcrum to the south. Because Quang Nam's biggest enemy has always been the Zheng lord of Hanoi in the north, their current power in the south is not strong, and the progress of colonization is relatively slow. Quang Nam's national policy is to use immigrants to slowly encroach on Cambodia.

After the death of Zheta II, he was succeeded by his eldest son, Boni. Du, the one who held the power was Prince Udie, the younger brother of Zheta II. New King Boni. Tuk came out of the monastery and ascended the throne directly, with no administrative experience, and worse, during a tour of Angkor Wat, the new king and one of Prince Udie's concubines rolled the sheets. The king and the concubine were childhood sweethearts, and they rolled the sheets and took her into the palace. The peachy incident angered the powerful regent, who incited the capital's military and civilians to rebel against the king's Chinese Janissaries and execute the king and his concubines.

He was succeeded by the second son of Zheta II, who lived peacefully on the throne for ten years before dying in 1640. This time, Prince Udie couldn't bear it anymore and directly supported his son Anon to ascend the throne. But just last year, in 1642, the third son of Zheta II, Anzan, converted to Celestial Christianity, changed his name to Ibrahim, married a Malay Celestial Sect princess, and won the support of the Champa and Malays who believed in Celestial Christianity. He led a powerful mercenary army in a military coup d'état, killing Prince Udie's family, with only Prince Udie's two sons escaping. One of them is in Hue and the other is named Padang. Raja's young prince is now under the control of the Golden City.

The support of the Malay Celestial Cultists was also a price to be paid for this King of Anzan. The desire for proselytism in Celestial Christianity is comparable to that of Catholicism. The ascendant King Anzan could not control his Celestial Cult wife and mercenaries, who slaughtered all the ministers appointed by Prince Udie in the capital, and took control of the government. Worst of all, during his reign, Prince Udie maintained good relations with the Dutch, who established a merchant house in Kampong Long, near Udong. The Celestial Merchants were unsuccessful in persuading Anzan to sever ties with the Dutch, and they privately launched a holy war. The Celestial Sect rebels, chanting "Jihad", stormed the Dutch Merchant House, killing the East India Company staff and burning the Dutch merchant ships.

Van Dimen was furious at this and dispatched five warships to attack Chenla. The Dutch blocked the mouth of the Mekong River for a while, but the effect was not obvious, and they ventured into the mouth of the Mekong River and encountered fierce resistance from the Khmers. Fleet Commander Hendrick. After learning that Jincheng and Siam were going to invade Chenla, Harus led the Dutch fleet to Jincheng and asked to join the coalition.

The order welcomed this, and the biggest variable in the dispatch of troops to Zhenla was the attitude of the Spaniards in Manila. The only nearby ones that could pose a threat to the Jincheng Navy were Batavia and Manila, after all, the Spaniards had a history of meddling in Jinla, and Shou Xu was worried that with the Jincheng Navy alone, if the Spanish fleet appeared in the Gulf of Siam, it would make the whole battle situation very passive. Now with the Dutch fleet, there was no need to worry about the Spaniards. Jincheng has 6 cruisers, the Dutch have 4, plus the frigates and notification ships of both sides, the Spaniards will not take advantage even if they come.

Quang Nam also sent an envoy to Kim Thanh, and the current king of Quang Nam is Nguyen Phuc Lan, who received the envoy Nguyen Thanh in the official residence. In front of the Dutch and Siamese, Ruan You saluted and said to Shouxu: "The current king of the Gao Barbarian Kingdom slaughtered Zhongliang and believed in cults in the country, and our lord (referring to Nguyen Phuc Lan) has been dissatisfied with this for a long time. Your coalition forces are crusading against the High Barbarian State, and our country is not against it. The Lord also agrees that if you take the four forks, you may charter our ships. ”

Nguyen Youjin is fluent in Chinese, and like North Korea, Vietnam is a country with a deep sense of sinicization. The aristocracy spoke Chinese, and only the inferior folk spoke the native dialect.

Although Chenla is also an ancient civilization in history, the Vietnamese, who regard themselves as Little China, have always looked down on other ethnic groups except their own country and China, and call Zhenla a high-barbarian. The Quang Nam army was still very combative, relying on the Europeans, they obtained advanced weapons, and recruited Portuguese instructors to establish a new army modeled on the European formation. If it weren't for the fact that the combat effectiveness of the army far surpassed that of Lord Zheng, they would not be able to deal with Lord Zheng with a tenfold inferiority.

The Dutch commander Harus asked: "Will your country send troops this time?" ”

Nguyen Youjin's answer was translated: "I'm sorry, Mr. Commander. Our army has to be used to guard against Zheng Rebellious, and it is unable to transfer it south. ”

Shou Xiang smiled, "Then what do you want to get?" ”

Ruan Youjin knew that Yangyi was a very direct person and would not go around in circles, so he was also prepared for this, so he said Quang Nam's request, "Our country wants to get the right to colonize Mehagi." ”

Quang Nam's southern invasion pursued the Khmer people in the lower Mekong valley step by step by relying on stronger national strength and more advanced civilization to avoid war as much as possible.

The people of Quang Nam obviously want to benefit but don't want to make too much effort. But as a powerful and pro-China country, Quang Nam is definitely the object that Jincheng needs to woo. Quang Nam's involvement in Jinla is also good for Jincheng, and Shou Xu glanced at the Siamese envoy beside him. It is not too good to let Siam completely control Chenla, and if Quang Nam intervenes, there will definitely be a conflict between the two powers. Historically, Siam and Quang Nam later intrigued in Chenla, supporting their respective proxies to wage war, and even went straight to war. At one point, the Siamese Navy also invaded the Mekong River.

Guangnan also has a prince of Chenla in his hands, and he thought for a while, "The intention of our three kingdoms to send troops this time is to overthrow the current regime of Chenla and support the son of Prince Udie, Padang. Rajah ascended the throne. What is your country's position on this? ”

"Our country is happy to see the descendants of Prince Udie ascend to the throne of Gaoman." Ruan Youjin said a living word. For Quang Nam, it must be more advantageous to support the Prince of Chenla, who is controlled by himself. However, the allied armies of Siam, Jincheng and the Netherlands, as well as possibly Nanzhang, were prepared to do real things, and Quang Nam could not afford to send an army, so it had to retreat to the next best thing, and exchange political recognition of the new king for land.

It's good to be recognized by Quang Nam, anyway, it's generous to others, and he waved his hand, "Envoy Ruan, please go back and tell the Lord of your country, you will get Mei Hagi." ”

The current Ibrahim of Chenla. King Anzan took a dose of fierce medicine in order to ascend the throne. The Celestial Sect and the mercenaries of the Champs aided him in his coup d'état, but they were also almost all the common enemies of the surrounding Buddhist countries.

Theravada Buddhism in the south is not like the submissive Zen Buddhism in China, and Theravada Buddhism has a strong political power in various countries. King Chenla spent his studies in a monastery before his accession to the throne. The suppression of Buddhism by the Celestial Cult after taking power was obvious, and if there was no invasion by foreign enemies, the swords and guns in the hands of the Celestial Cult mercenaries might have given King Anzan time to secure the throne and clean up the factions in the country. But Order doesn't give Anzan a chance to consolidate his rule now.

At the same time as Jincheng sent troops, he also contacted the Theravada Buddhist monasteries in Chenla through the remnants of King Udie, and they did not oppose Jincheng's dispatch of troops this time. Thieves are always more hateful than foreign enemies, and in the eyes of the Buddhist monasteries that cooperated with Jincheng, Anzan's introduction of the Heavenly Sect was even more dangerous than that of the Siamese. All Southern Buddhism remembers that originally the Malay Peninsula and Java were Buddhist countries, but since the introduction of Celestial Sect merchants, in just 200 years, these Buddhist countries have disappeared and become Celestial Sect countries.

Note: Historically, the Dutch attack on Chenla in 1643 was unsuccessful. The blockade effect of the five ships was very limited, and such a small number of troops could not land and fight a land battle with the Khmers, and the state of war between the Dutch and Chenla lasted for 9 years. However, the Dutch were unable to defeat King Anzan, and it was Quang Nam who finally eliminated this strange Muslim king in the history of Chenla. In 1658, Quang Nam sent troops to capture Anzan and support Padang. Rajah ascended the throne. Udie's son defected to the widow of Zheta II, and the Udie's family and Zheta were political enemies with blood feuds, all of which could unite to scare Anzan, which shows how annoying this king of the Heavenly Sect is.
