On July 18, 1762, Peter III suddenly died after Catherine the Great staged a coup against him, but the cause of his death remains a mystery to this day. As one of the most short-lived emperors in Russian history, Peter III's reign was marked by controversy and turmoil. Whether Catherine was involved in his demise has become a topic of debate among historians.

Peter III's father, Peter the Great, was a visionary leader, but his son showed little affection for Russia and openly disparaged his homeland upon his return. Catherine, a German princess of humble origins, worked tirelessly to become a clever and ambitious empress. She employed various means to consolidate her power and ultimately succeeded in overthrowing Peter III in 1762.

The circumstances surrounding Peter III's death are shrouded in speculation; some believe he was poisoned, while others suggest he was killed in a drunken brawl. There are even rumors that Catherine ordered him to be strangled. Regardless of the truth, Peter III's death is undoubtedly intertwined with Catherine's power struggle.
