Catharina Rickert

Catharina von Wartenberg née Rickert (Emmerich, 1674 – The Hague, 1734), known as "Catharina, Reichsgräfin von Wartenberg" or Madame de Wartenberg, was the official royal mistress of king Frederick I of Prussia between 1696 and 1711.

Life Catharina von Wartenberg was of middle-class origin, as the daughter of a tax collector for the Brandenburg court to the Duchy of Cleves in Emmerich am Rhein. She came to Berlin as wife to Kammersekretär Peter Biedekap, where she became the lover of the court official Baron von Kolbe, called Minion and one of the favorites of Frederick I. After the death of her spouse in 1696, von Kolbe married her, and the same year, he introduced her to Frederick I, and she became his official mistress.

Royal favorite It is unconfirmed whether she ever actually functioned as the mistress of Frederick I in a physical sense, but it was very fashionable at the time for a monarch to have an official mistress at his court, in the manner of Louis XIV of France, and Frederick I made a point of spending time with her every day and appear with her openly at court. She was also given the title Countess of Wartenberg. Though they may not have consummated their relationship sexually, Catharina von Wartenberg reportedly did have some influence over the king, as well as she had influence over her spouse, himself an influential favorite of the king, and she was at the time resented as "the daughter of a tavern-keeper who rules Prussia". She was described as politically ambitious and her position made her controversial, particularly in the eyes of the king's male favorites, such as the English ambassador, Lord Raby. The queen, Sophia Charlotte of Hanover, reportedly snubbed her on several occasions.

When queen Sophia Charlotte died, von Wartenberg was awarded the estate of Woltersdorf. Catharina von Wartenberg reportedly had the pretensions of replacing her, caused women of the nobility to boycott the king's royal assemblies three times a week and "the Court became a perfect desert." In 1708, the king asked her for advice whether he should marry again, but she declined to answer. the ambassador asked the king to command her to attend, but when she was informed that she would not take precedence before the ambassador's spouse Madame de Matuoff, she refused to attend. This resulted in a formal complaint presented to the king by all the foreign ambassadors in Berlin except the English. The king demanded that von Wartenberg make a public apology to de Matuoff, and she was forced to read her apology, standing to the seated Matuoff; after which she tore up the apology, but it was nevertheless printed in a gazette by the ambassadors and publicly circulated. Shortly after, the king told her that if she kept causing diplomatic incidents, "he would find means to put a stop to it."

After this incident, von Wartenberg advised her spouse to leave the court, but he did not take her advice. The crown prince and his favorite Grumbkow, the foreign minister Ilgen and the two courtiers Kamecke the Elder and Younger, took the incident as a pretense to accuse von Wartenberg for being an English agent through her association with Raby and investing in English securities; after undermining her influence, they proceeded to implicate her spouse, who lost his position in January 1711.

Later life Catharina von Wartenberg followed her spouse to in exile to Frankfurt, bringing with her jewels valued at 500,000 Thalers. Her spouse was soon offered to return to service, on condition that he leave her behind, but he replied that he could not agree to that term. She became a widow in 1712, and remarried the French noble Marschall d’Huvelles, with whom she settled in Paris. The final years of her life, she lived in The Hague.
