The heirs of Peter the Great. Who saved the Russian Empire?

It was a time of conspiracies, intrigues, espionage, and revolutions... The historical period after the death of Peter the Great, when Catherine I, Peter II, Anna Ioannovna, Biron, Anna Leopoldovna took turns at the helm of the state, remains largely unknown. Researchers often consider it dark, cruel, dull, and uninteresting. Therefore, they briefly skim over it or completely avoid it.
However, in reality, this era turns out to be exceptionally important. Just after the achievements of Peter the Great, the birth of the mighty Russian Empire, the interests of various groups within the country clashed with those of foreign powers seeking to weaken it, plunge it into chaos and turmoil. Its very existence was threatened. But it withstood, maintained its status as one of the leading world powers. It defeated external enemies and troublemakers, achieved new outstanding successes. A new work by the well-known writer-historian Valery Shambarov, "The Heirs of Peter the Great. Who Saved the Russian Empire?" tells about these events.
