In the article the 1950s uprising of the Syr-Darya Kazakhs, led by Zhankozha Nurmuhameduly, as a response to the encroaching expansionist policies of Imperial Russia was considered. It uncovers the oppressive tactics employed by the tsarist government's local officials. The study highlights how the construction of coastal forts along the banks of Syr-Darya River enabled control over the pastures and wintering grounds of the Jun-ior Horde Kazakh clans. The study additionally reveals archival discoveries, such as the substitution of the Hojaniyaz fortress, which fell due to the directives of the Orenburg frontier commission, with the Kazaly fort. The study links these events to the revolt of the disenfranchised tribes in the lower Syr-Darya region. Through the use of newly available archival data, it offers a detailed examination of the structure and pro-gression of the uprising. Furthermore, the research thoroughly details the arming of Russian-Cossack forces with sophisticated weapons, ammunition, and technical means employed to suppress the rebellion. The re-search posits that the timeframe of the Syr-Darya Kazakhs’ liberation uprising spanned from 1856 to 1862, thereby contesting the previously accepted historical timeframe of 1856-1857.
