Pugachev's Rebellion
Pugachev's Rebellion (Peasants' War 1773-75, Cossack Rebellion) of 1773-75 was the principal revolt in a series of popular rebellions that took place in the Russian Empire after Catherine II seized power in 1762. It began as an organized insurrection of Yaik Cossacks headed by Yemelyan Pugachev, a disaffected ex-lieutenant of the Imperial Russian Army, against a background of profound peasant unrest and war with the Ottoman Empire. After initial success, Pugachev assumed leadership of an alternative government in the name of the assassinated Tsar Peter III and proclaimed an end to serfdom. This organized leadership presented a challenge to the imperial administration of Catherine II.

In the letter to Catherine II of Russia he wrote: "I expect from v. V. of the resolution of the boundary local matter not on the Polish statutes, but on the zbornomu (cathedral) packing code". It notes after the transfer from Poland Bibikov: "I will finally not be obstacle I see and to the intentions of the managers fate Polish".
During this campaign Bibikov fell ill with cholera and died, aged 44, Empress granted large estate to its family. All data attest to the fact that Bibikov connected the bright military and administrative abilities, large diplomatic time with the independence of persuasions and the incorruptible honesty.
