Catherine of Pomerania (German: Katharina von Pommern; c. 1390 – 4 March 1426), was a Pomeranian princess, and a Countess Palatine of Neumarkt as the wife of John, Count Palatine of Neumarkt, and the mother of Christopher of Bavaria, king of the Kalmar Union.
Catherine was the daughter of Wartislaw VII, Duke of Pomerania in Pomerania-Stolp and Maria of Mecklenburg-Schwerin.
Catherine's brother was Erik of Pomerania, future king of Denmark, Sweden, and Norway.
The English had wished for Catherine's children with Henry to inherit the Nordic thrones in the case of Erik dying without an heir (which was impossible since the Kalmar Union was elective), as well as an alliance against France, which Margaret could not agree to.
[6] The negotiations were completed in one year, and Margaret gave Catherine a dowry of 4,000 gulden, much less than was expected by her future father-in-law.
