Yemelyan Pugachev
Yemelyan Ivanovich Pugachev () (c. 1742 – ) was a Russian Cossack who led a great popular insurrection during the reign of Catherine the Great, claiming to be her late husband, Emperor Peter III. Alexander Pushkin wrote a notable history of the rebellion, "The History of Pugachev", and he recounted some of the events in his novel "The Captain's Daughter" (1836).
Dmitry Mertvago
From 1807, at the insistence of Derzhavin, Mertvago began working on the "Notes" in which he described the events of the Pugachev's Rebellion, the reign of Emperor Paul I, and he gave portraits of prominent statesmen of the late 18th – early 19th centuries.
