As Central Thai rule was unpopular among the local
Shan people, 50 rioters stormed the local police and post office on 24 July 1902 in an act that would begin the
Ngiao rebellion. The rebels, now numbering in the hundreds, were led by Slapochai and Phaka Balm who travelled to Phiriya's residence in Khum Chao Luang where they allegedly convinced him to support their movement and to also provide food, supplies and weapons to the rebels. Under rebel control, local Central Thais were rounded up and executed, including the governor Thongyuu Suwanbat. The rebellion would end when
Chao Phraya Surasak Montri led Siamese soldiers to Phrae. Fearing his army, the rebels would split into 2 armies which were
simultaneously defeated. On August 4, Phrae would be recaptured by provincial forces led by the Governor of Pichai, Phraya Srisuriyarajvaranuwat. Following the rebellion's end, Surasak Montri led an investigation around the rebellion, coming to the conclusion that Phiriya's support helped the movement grow. Fearing punishment, Phiriya's family and wife committed suicide by drinking poison. Fearing that this would cause a misunderstanding where the Siamese government would be accused of violence against the Royal Family, Surasakmontri began spreading rumours that Phiriya will be arrested. Scared by these rumours, Phiriya escaped Phrae with 2 friends. His escape was supported by Surasamontri who gave out secret orders to troops stationed around the city to not prevent his escape. After 15 days, it was determined that he abandoned his positions against ruler and the role of king would be abolished by Surasakmontri on September 25, 1902. == Exile ==
