Matilda Kristina von Schwerin née Hagberg (1818 – 1892) was a Swedish countess and landowner. She was a central figure in two great scandals in 19th-century Sweden; when her future husband's brother sued him for his intending marriage to her on accusations of incest (1841–44) and when her late husband's brother refused to acknowledge her legal right to her inheritance and dower land after her late spouse (1849–56), known in history as the 'Schwerin Estate's Scandals'. Life Early life She was the daughter of an employee of the Royal Lottery, Lorentz August Hagberg, and Christina Carolina Schelin of Stockholm. Her mother was the mistress of the rich landowner count Curt Philip von Schwerin (1795-1849), and when Matilda Kristina's father died, she and her siblings moved from Stockholm to the estate of von Schwerin in Östergötland. Her mother was formally employed as the housekeeper of von Schwerin, but she was known to be his mistress and their relationship was a scandal: von Schwerin's brother and heir, the courtier Adolf Henning von Schwerin (1799-1878), was reportedly afraid that his unmarried, childless brother would marry his mistress. Curt Philip von Schwerin was one of the richest landowners in Sweden, owner of a number of estates such as Husby, Fyllingarum, Sverkersholm, Borkhult, Gobo, Odensgöl, Ekhammar and Åketorp. However, von Schwerin, though owner and resident on his estate, did not have financial control over his properties, as his inability to handle the inherited debts of his late owner and predecessor had resulted in his estates coming under the legal administration of his brother, an official of the royal court, who was in fact his heir. First scandal In 1841, Curt Philip von Schwerin announced that he would marry, not his mistress, but her daughter, Matilda Kristina. He was sued by his heir and brother Adolf Henning von Schwerin, who accused his brother of intent to commit a crime, as a marriage to the daughter of his mistress would juridically be defined as incest by the laws of prohibited degree of kinship. This led to a three year long legal process, including testimonies regarding the sexual relationship between Curt Philip von Schwerin and Christina Carolina Hagberg, before the court declared Curt Philip von Schwerin free to marry Matilda Kristina Hagberg in 1844. The legal process was a three year long scandal in contemporary Sweden. Count Curt Philip von Schwerin married Matilda Kristina Hagberg in 1844, and
