After the fall of Angkor, the conquest of Longvek was another blow to Khmer sovoreignty, which was not restored for many more centuries, initiating the period known as the "dark age" of Cambodia.

[5] Khmer King Ang Chan I (1516–1566) is said to have moved and founded the new capital north of Phnom Penh to Longvek on the banks of the Tonle Sap River.

A Portuguese named Diogo Veloso arrived with a handful of men to form the Royal Guard, he was joined by a Spaniard Blas Ruiz in 1592.

They encouraged him to seek an alliance with the Spaniards established in the Philippines thus threatening the Siamese domination of the Khmer Empire since their defeat at Angkor in 1431.

[8] A  first Siamese campaign against Cambodia was launched in 1591, and the Longvek citadel was besieged but after three months, a combination of logistical issues and Cambodian counterattacks forced the Thais to retreat beyond the border.

These Khmer soldiers, eager to obtain this gold, would have razed the forest to recover this loot, thus depriving themselves of their protection and giving the city into the hands of the Siamese invaders.

Although King Satha managed to escape into neighboring Laos, Cambodian royals were taken hostage and relocated to the court of Ayutthaya, kept under permanent Siamese influence, and left to compromise and out-compete each other under the overlord's scrutiny.

[11] According to the Cambodian Chronicles, after King Satha decided to transfer his power to his two sons, the elder of whom was 11 years of age and the other 6, the Uparāja Srī Suriyobarm and mandarins felt frustrated that such young men would be appointed to lead the nation in a time of crisis.

A Buddha image at Wat Vihear Suor bled and the leaves of a bodhi tree at Longvek fell out of season while an epidemic of cholera spread to all the corners of the kingdom.

[13] The military defeat may be due to shortcomings in terms of artillery, as suggested by the Cambodian chronicles composed in the late 18th-early 19th century regarding the fall of Longvek.

[17]In the Siamese Chronicles, King Naresuan needed to obtain revenge from the Khmer who had abused him when he was in a weak place after the Burmese invasion of Ayuatthaya.
