Princess Katharina of Württemberg (full name: Friederike Katharina Sophie Dorothea; [1] 21 February 1783 – 29 November 1835) was Queen of Westphalia by marriage to Jérôme Bonaparte, who reigned as King of Westphalia between 1807 and 1813.
Upon marriage, Katharina became Queen consort of the Kingdom of Westphalia. Reportedly, Katharina and Jérôme bonded strongly and had a happy marriage, remaining firmly attached to each other. King Jérôme, however, was unfaithful with multiple partners, including a three-year relationship with Diana Rabe von Pappenheim, but Catharina chose to turn a blind eye.
When the kingdom of Westphalia was dissolved in 1813, she followed Jerome to France. During the war, she and Désirée Clary took refuge with Julie Clary at Mortefontaine, and when the allied troops took Paris, they took refuge in the home of Desirée Clary in the capital.[3]
After the downfall of the Napoleonic Empire in 1814, her father expected her to separate from Jerome, as Empress Marie Louise had done from Napoleon, but instead she followed him into exile to Trieste in Austrian Italy.
During the Hundred Days in 1815, she helped Jerome to escape and join Napoleon, and was as a consequence deported to Württemberg, where she was placed under house arrest. After the defeat of Napoleon, she was joined by her spouse in house arrest.
Katharina and Jerome were eventually released from house arrest and spent their remaining life together in Trieste and Switzerland, under the name of the Princess and Prince of Montfort. In November 1835, Katharina died in Lausanne, Switzerland.
