Step-by-step explanation:
Who is Known as the "Infant Tsar"?
The title of the "Infant Tsar" refers to Ivan VI. Ivan VI was an infant when he was proclaimed Emperor of Russia in 1740, but his reign was short-lived. He was overthrown during a palace coup led by Elizabeth, Peter the Great's daughter, who became Empress Elizabeth. Therefore, the correct answer is b. Ivan VI.
Elaborating on the context, the concept of the Tsar, which is Russian for 'Caesar', has a long lineage, starting from Ivan IV (Ivan the Terrible), who was the first to declare himself Tsar of all the Russias in the mid-16th century. The Tsars of Russia have often been central figures in the country's history, with notable rulers like Peter the Great, who significantly modernized Russia. Empress Catherine II, also known as Catherine the Great, was another significant ruler who, despite being an 'enlightened despot', enforced a strong authoritarian rule under the guise of a social contract.
