Catherine of Brunswick-Wolfenbüttel was a member of the house of Welf and a Princess of Brunswick-Wolfenbüttel and by marriage Duchess of Saxe-Lauenburg.
Background
Catherine was a daughter of the Duke Henry IV of Brunswick-Lüneburg (1463–1514) from his marriage to Catherine of Pomerania (1465–1526), daughter of the Duke Erich II of Pomerania. Her father summoned the Parliament in 1509 to collect a lady tax, because he found himself unable to pay the dowry alone.
Career
Only after long negotiations, did the Parliament grant three rounds of real estate tax, to generate for money for a dowry and jewels for the princess. Catherine was a strict Catholic with close ties to her relative in Brunswick kin. Francis I (1510–1581), Duke of Saxe-Lauenburg
