The French refused to help King Norodom put down Si Votha's revolt until the king concluded a treaty which advocated several reforms. By January 1877, the treaty was concluded and on 15 January, King Norodom proclaimed a series of reforms under the new treaty. In return, the French now bent their efforts to defeating Si Votha's uprising. Si Votha's uprising lasted until 1885-1886 with the help of Khmer Prince
Duong Chakr, Norodom's own child. It was Norodom's prestige that ultimately brought Si Votha's resistance to an end. Si Votha, lurking on the northeastern boundaries of the kingdom, was a nuisance but nothing more. For the inhabitants of the northeastern region of Cambodia, Votha remained a king and he maintained his own small, if impoverished, court. After the failure of his efforts in 1885-1886, his followers became fewer, dwindling to a few companions by the time he died. In the closing years of his life, Si Votha entered into hesitant and inconclusive negotiations with the French. Having grown tired of living amongst the less civilized
hill tribe people in the jungle of northeastern Cambodia, Si Votha eventually submitted to the French. However, he strongly emphasized his refusal to submit to his half-brother, King Norodom. The French, who were attempting to expand their influence in
Cambodia at the time, were pleased by Si Votha's defeat, as he had been an outspoken critic of
European colonialism in the area. Si Votha became something of a figurehead for resistance against the French. Si Votha's rebellion was largely unsuccessful, however, and in 1887, Cambodia was incorporated in the French-controlled
Indochinese Union. ==Defeat and death==
