The Ngiao rebellion (), also called the Phrae City Rebellion and the 1902 Shan rebellion, was an uprising of Tai Yai (Shan, historically known in Thai as Ngiao) people against Siamese rule, in what is now Phrae province in northern Thailand between 25 July and 14 August in 1902. It arose as resistance to centralizing reforms initiated by King Chulalongkorn, particularly the levying of taxes and the adoption of the Monthon Thesaphiban provincial administration system, as well as the partitioning of territory with the British, which forced the Shan to adopt either British or Siamese nationality.
In the morning of 25 July 1902, rebels attacked and looted the town of Phrae, killing over twenty government officials including the royal commissioner, Phraya Ratcharitthanon. The rebellion was soon quelled by troops from Bangkok led by Chaophraya Surasakmontri, as well as Siamese troops commanded by British and Danish officials. Ten rebel leaders were executed, sixteen were taken to Bangkok for imprisonment, and Chao Phiriya Theppawong, the ruler of Phrae, escaped into exile in Luang Phrabang. The rebellion, aimed at overthrowing Siamese rule over Lanna, continued onward as an insurgency until 22 May 1904 and spanned across Northern Siam.
The revolt was part of several acts of resistance that arose in the fringes of the country in the 1890s to early 1900s. A few months earlier, the Holy Man's Rebellion in the Northeast saw rebels sack the town of Khemmarat before being routed by the Siamese army. While it was unclear whether and to what extent the local rulers supported the rebellion in Phrae, the local lordship of Phrae was ended, and further reforms were put into place that helped Siam fully annex the former lands of Lanna and assimilate its people.
History
Background During the reign of King Chulalongkorn (Rama V) and his predecessor, Siam had lost numerous territories to France and Britain, normally lands ethnically non-Thai. In 1885, Siam was forced to cede its northern Shan provinces, which partitioned the Shan people between British and Siamese rule. In order to tighten and retain the land left, King Chulalongkorn began passing reforms which centralized the country around Bangkok and reduce the power of local rulers, with local rulers in the country's north being forced to hand over higher taxes and most of their power.
On 10 October 1899, a previous revolt occurred in Chiang Mai against increased taxes. The revolt was led by Phya Pap and aimed to install him as king and expel all Siamese and Chinese people from the area. The revolt was poorly organized and collapsed quickly.
In Muang Prae, Phraya Chaiboon (Thongyuu Suwanbat) was appointed as governor in 1897. The previous leader Chao Phiriya Theppawong had previously ruled Phrae as the local king under Siamese vassalization similar to Kingdom of Chiang Mai and other northern states.
One of the principal leaders of the rebellion, Phaka Mong, fled to Siam from Kengtung due to large amounts of debt he owed to the local ruler. In Siam, his main revenue was banditry.
Tensions before the rebellion In early July 1902, Siamese police attempted to arrest a group of Shans in a ruby mine in Baan Baw Kao, south of Phrae town, without consulting the head of the mine, Sala Po Chai. The Shans resisted and fighting broke out with the police, resulting in the death of several policemen. The police retreated from the mine and assembled a force of 80 police and soldiers equipped with horses and elephants. They then began advancing back towards the mine on 23 July but were ambushed by the Shans in a ravine which led to the mine. The ambush destroyed the Siamese who fled to Lampang. Here, the Shan killed 16 Siamese and took possession of the Siamese equipment which included horses, elephants, guns and ammunition. Knowing that they would face retaliation from the Siamese in the future, the Shans led by Sala Po Chai and Phaka Mong set out on a rebellion.
Early days On 25 July, 50 Ngiao rioters stormed the local police station in Phrae and due to the small amount of officers inside, easily took over the station and seized weapons, killing numerous policemen. Despite warnings, Phraya Chaiboon had not permit the police to have ammunition, most likely as he did not trust the police as they were recruited locally. Afterwards, rioters destroyed telegraph lines and stormed the governor Phraya Chaiboon's residence. However, Chaiboon had already fled the town with his wife Lady Yean to seek help. With the governor gone, the rioters took the treasury's money totalling 46,910 Baht and killed the remaining servants in the building. The rebels also managed to equip themselves with Austro-Hungarian Mannlicher–Schönauer rifles after storming the police station. They then went to the local prison to increase their numbers from 50 to 300. In the chaos, many villagers fled Phrae, although the rioters told the town folk that they would not be harmed but instead the Siamese who ruled over them. Led by Phaka Mong, their numbers soon increased with local villagers joining their cause. The leaders, Slapochai and Phaka Mong, travelled to Khum Chao Luang where they convinced Phiriya Theppawong there to join their cause and to also provide food and weapons. The rebels also presented their case to British officials in the town who were employed by the Siamese Forestry Department. Paka Mong stated the Shans' situation of "constant oppression by the Siamese officials" and their demand to oust the oppressive Siamese and restore the ruler's former power.
On 26 July, the Ngiao began hunting ethnic Central Thais (Siamese), but also encouraged their murder through prizes totalling 400 Baht per person, including women and children.
Three days after fleeing Phrae, Chaiboon went to local villagers in Ban Rong Kat to beg for food. In hopes of taking a prize, one of the villagers reported Chaiboon to the rioters and he was later arrested. Once back in Phrae, the Shan began forcing him to give up Phrae to the Shan, although he never signed. Chaiboon was later killed by one of the rioters, Jeong Shen, after challenging them to kill him. The site of Chaiboon's death is now a monument and Chaiboon was later promoted to Phraya Ratcharittanon Paholpolpakdee. Along with Chaiboon, numerous Siamese officials were murdered. However the former treasurer of the Phrae, Phra Wichai Racha, hid three Siamese government officials from being murdered by rioters. In addition to the local residents, Westerners were unharmed such as Dr. Thomas who led an American Presbyterian mission in Phrae. In total, 20 Siamese officials were murdered, making it the largest massacre of Central Thai officials in Northern Thailand.
Battle of Lampang
Upon learning of the situation in Phrae, King Chulalongkorn assigned Chao Phraya Surasak Montri to lead Siamese forces from Bangkok to suppress the rebellion whilst local troops from nearby towns were called in to assist. Upon learning that Surasak Montri was heading north, the Shan split their army into two divisions - with Salapochai leading the men in the south whilst Phaka Mong lead troops to attack Lampang. Bolden by their success in Phrae, Phaka Mong and Sala Po Chai drew up plans for the liberation of Northern Thailand, planning to continue on to Chiang Mai, Lamphun, Phayao and Chiang Saen after a victory at Lampang.
News of a Shan attack on Lampang came from Nai Fuang, a judge from Phrae, who escaped and telegraphed this information of 26 July. The King of Lampang, Bunwatwongse Manit began preparing his town's defences by assembling a force of 1,000 irregulars. To prevent Lampang's prisoners from joining the rebels like the prisoners in Phrae did, all the prisoners were executed. From Chiang Mai, 54 policemen were sent to Lampang under the command of Danish captain Hans Markvard Jensen. Jensen had arrived in Siam as a police trainer from Denmark. They arrived on 29 July. At the same time Lampang at been substantially fortified, with nine v-shaped teak barricades erected under the orders of British teak company officials blocked major roads into the town. Most of the town's defenses had been coordinated by Louis Leonowens, son of Anna Leonowens.
On 3 August, Phaka Mong's forces arrived at Lampang and began attacking the town on 4 August during dawn with 200 men. His forces advanced towards Chao Bunwatwongse's residence along Bunwat road and while another was beside the Wang river. The Shans along the river seized the barricades there but the forces along Bunwat road failed to take barricades held by Captain Jensen and Lt Tjoen. Jensen then led his forces to fire upon the Shans along the riverside. Along the riverside, the Shan came under constant fire including from Leonowen who was firing from the Chao's residence where he was protecting the Chao and the Siamese Commissioner. The Shans began fleeing from Lampang before being followed behind by Lampang's forces who were promised 300 Baht for each Shan soldier. This counteroffensive would end up killing at least 25 Shans, including Phaka Mong. Together, their heads were displayed in front of the Chao's residence on sticks.
Despite Phaka Mong's failed offensive, officials in Chiang Mai and Lampang were still unsure on whether the Shans would launch further attacks. In Chiang Mai, the city gates were barricaded and 5,000 soldiers were recruited in the city's defences. Under Jensen and Leonowen, the Chao of Lampang was evacuated to Chiang Mai. This however caused Lampang to fall into anarchy for three days with widespread killing and looting as they were without any rulers. On 7 August, Bunwatwongse returned to Lampang and restored order. For Captain Jensen's role in defending Lampang, Chulalongkorn intended to promote Jensen to rank of Major General and bestow him with the Order of the Crown of Siam and 10,000 baht. However Jensen was later shot dead at 24 along with Lt Tjoen by Shan rebels on 14 October 1902 at Muang Ngao after being abandoned by his men, apart from Tjoen. Chulalongkorn honoured Jensen by paying an annual pension of 3,000 baht to his mother until her death in 1938. The King also donated an obelisk to Jensen's grave in Chiang Mai.
Siamese capture of Phrae On 5 August, the 24 year old British vice-consul based in Nan, Harold Lyle, was dispatched by British officials in Chiang Mai arrived into Phrae and moved into the former residence Phraya Chaiyabun in an attempt to restore order. Lyle began writing to Sala Po Chai urging him to not engage with Surasak Montri in battle. He also attempted to raise the morale of the foreign residences by organizing a game of polo. On 7 August, defeated Shans from the Battle of Lampang started returning to Phrae where Lyle encouraged them to disperse and flee to British Shan territories. However, Sala Po Chai did not follow Lyle's wishes and Lyle rode 8 km on 13 August to meet with recently arrived Siamese forces under the authority of the governor of Pichai, Srisuriyarajvaranuwat. There, he delayed the Siamese from entering Phrae by saying that Phrae had no rice to feed his men and that if they encountered a Shan army, they would be destroyed. This was due to his fears that it would result in a massacre of local and foreign residences for three days. During this, more Siamese soldiers arrived and were led by Danish commander-in-chief of the Siamese Provincial Military Police Gustav Schau. At the same time, Salapochai's forces in the south were defeated by armies from Sawankhalok and Sukhothai. On 16 August the governor of Pichai, Phraya Srisuriyarajvaranuwat, led provincial police and took over Phrae. Surasak Montri arrived in Phrae on 20 August.
