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).
The Captain's Daughter
After Masha has been freed, she and Pyotr take off to his father's estate, but they are intercepted by the army. Pyotr decides to stay with the army and sends Masha to his father. The war with Pugachev goes on and Pyotr rejoins the army. But at the moment of Pugachev's defeat, Pyotr is arrested for having friendly relations with Pugachev. During his interrogation, Shvabrin testifies that Pyotr is a traitor. Not willing to drag Masha into court, Pyotr is unable to repudiate this accusation and receives the death penalty. Although Empress Catherine the Great spares his life, Pyotr remains a prisoner.
