Princess Catherine Bagration née Skavronskaya was a Russian princess, married to general Pyotr Bagration. She was known for love affairs and unconventional behaviour, she was the daughter of Count Pavel Martinovich Skavronsky, Chamberlain of the Royal Court and Minister Plenipotentiary to Naples, well known for his mental imbalance and extraordinary love of music, Yekaterina von Engelhardt, niece and at the same time favorite of Prince Grigory Potemkin. She was educated at the court of the Empress Catherine II the Great and the Empress Maria Feodorovna, wife of her son Emperor Paul I. In 1800 the Paul I of Russia, well known for his caprices, found out that General Pyotr Bagration, a Prince of the Bagrationi dynasty, was secretly in love with Catherine; the Emperor used to marry members of his court off to each other, one day at the Palace of Gatchina he announced that it was his intention to attend the marriage of General Bagration and Countess Catherine Skavronskaya. The Countess was said to be in love with Count Peter von der Pahlen, the prospective groom was shocked.
Nobody however dared to argue with the monarch, the wedding took place on 2 September in the chapel of the Gatchina Palace, near St. Petersburg; this is what General Louis Alexandre Andrault de Langéron had to say about this union: "Bagration married the young niece of the great Prince Potemkin. This rich and lustrous partner did not suit him. Bagration was a mere soldier, with the tone and manners of one, he was ugly, his wife was as white as he was black, she was as beautiful as an angel, the liveliest of the beauties of St. Petersburg. In the year 1805 the Princess broke up with her husband and went to Europe; the couple had no children. She traveled so extensively that she had a special carriage made, with an elegant ladder that allowed her to climb in and out of it comfortably, it had a bed inside, all the luggage was placed on the outside. She called her carriage her dormez or'sleeper'. Prince Bagration called her back to Russia a number of times, sent her so many letters that her friends tried to persuade her to go.
In Europe Princess Bagration was a great success, became well known in court circles. She became notorious everywhere and was called le Bel Ange Nu because of her passion for revealing dresses, Chatte Blanche, because of her unlimited sensuality. Lord Palmerston noted in his memoirs that the Princess only wore translucent Indian muslin, which adhered to her figure. From her mother, she had inherited an angelic face, alabaster white skin, blue eyes, a cascade of golden hair; when she was thirty it was said she still had the skin of a fifteen-year-old. Her husband the Prince, refused to hear a word said against her, insisting that the affairs of his household were his business alone, her huge expenditure on receptions and clothes belied her claims of sickness, but he remained a generous husband and continued to pay her bills. The Prince remonstrated with the Princess's mother, who had started to get irritated by her daughter's extravagance. In 1808, a military Order was awarded to the wives of those generals who had distinguished themselves in the recent war.
Princess Bagration was bypassed, the pride of her husband was wounded. He argued that Ekaterina bore his name, and, enough: "She should be rewarded, because she's my wife...". The Prince paid thousands of roubles for debts Princess Catherine had accumulated from living in Vienna. There were rumors about her connection with the Saxon diplomat Count Friedrich von der Schulenberg, a Prince of Württemberg, Lord Charles Stewart and others. Goethe met her in Karlsbad, admired her beauty; the Prince soon died in the Battle of Saalfeld, the princess returned once more to Vienna. She became the mistress of the influential Prince Klemens von Metternich and had a daughter by him in Vienna on 29 September 1810, whom she named Marie-Clementine after the father, who acknowledged his paternity; the daughter lived with the Metternich family from 1814 until getting married. Princess Catherine was an emancipated lady for her age, played like a man, choosing for herself which man to take as lovers, which as just friends.
After travelling for many years between one European capital and another, she settled in Vienna. Based there the Princess made her home into one of the most brilliant salons of society, a distinctly pro-Russian, anti-Napoleonic salon; the Princess set up a covert diplomatic post without any official authorization. Her salon was filled with the rich and famous, she corresponded with him and Bulgakov. She boasted. Under her influence, Austrian high society began to boycott the French Embassy. Napoléon found her to be a serious political opponent; as a result of her closeness to Prince von Metternich, she was able to persuade him to let Austria join the anti-Napoleonic coalition. Prince Bagration, despite his age, continued to fight for Russia in the Napoleonic War. At
