in the campaign “Introduction of Military Settlements and Liquidation of the Danubian Sich (1817–1828)”
The transfer of Cossacks to the status of rightless military settlers (the Arakcheev system), which provoked the uprising of 1817: "The trigger was the order abolishing the Buh Cossack Host and turning the Cossacks into military settlers… The reprisal against the rebellious Cossacks was extraordinarily brutal: many were cut down with sabers, drowned in the Southern Buh, flogged to death"[1]. There were two acts, on opposite sides of the uprising: the nominal decree of April 17, 1817 transferred the Buh Host's district "into direct military administration" (PSZRI, vol. XXXIV, no. 26,802) - this was the trigger; the decree of October 8, 1817 (no. 27,081), issued after the suppression, formalized the liquidation: "the name of the Buh Cossack Host is abolished"[2].
