The first season tells the story of princess Sophie Friederike Auguste, and her rise to power to become Empress of Russia, following a coup d'état and the assassination of her husband, Peter III.
Sophia Frederike hopes to find happiness in the distant and foreign land, but she is faced with the intrigues and plots of the Russian Imperial court, the indifference of her husband, and the plans of the Empress.
The girl takes the name Catherine Alexeevna (Yekaterina) and works to save herself and her children from danger, as the emperor Peter III desires to send her away from the palace.
In July 1762, barely six months after becoming emperor, Peter commits the political error of retiring with his Holstein-born courtiers and relatives to Oranienbaum, leaving his wife in Saint Petersburg.
However, Orlov's cheeky and unpredictable behavior, as well as his problems with male health, make the empress abandon her thought of marriage and send her son Alexey abroad.
Having got rid of Orlov, Catherine falls in love with the guard Grigory Potemkin and finds in Europe a bride for Pavel Petrovich, Wilhelmina Louisa of Hesse-Darmstadt.
Catherine releases the Braunschweig family, children of the Duke Anton Ulrich – the great-grandchildren of Peter the Great's brother, from prison.
Catherine opens a statue of Peter the Great in Saint Petersburg and sends Pavel Petrovich with his wife and children on a trip to Europe.
The prequel tells the story of the Empress Elizabeth, daughter of Peter I, who was all but 16 years old, when her father died and left her to govern her immense empire.
His Serene Highness Prince Potemkin, the former favorite and married husband of Catherine, remains a faithful comrade-in-arms and, in fact, the second person in the state.
A review at Eclectic Pop described it as "a vivid and beautifully crafted series replete with lavish costumes and a stirring musical score".
[4] Writing for BroadwayWorld, Robert Kahn described the series as "gloriously filmed" and added: "The story of Catherine's rise to power rivals any contemporary soap opera, as an intricate web of politics, adultery and betrayal unfolds within the Russian court in spectacular fashion.
