Two revolutionary movements occured during nineteenth century in the Gadjat areas of Orissa. One was a socio-religious movement led by Bhima Bhoi and the second was a political movement led by Surendra Sai. Both were mass movements against the existing socio-economic and political order. First War of Independence i.e. Mutiny in the year 1857 was an important occurrence in the history of struggle against British Raj in India. Contribution of Orissa in this historical event was significant and noteworthy. In Gadjat states the movement had deep impact. Involvement of natives under the leadership of Surendra Sai particularly in Sambalpur region was remarkable and worth mentioning. They contributed to it to a large extent prior to the outbreak of this mutiny and continued to struggle for the cause, till the climax and even after.
