Elisabeth of Brandenburg, Duchess of Brunswick-Calenberg-Göttingen

Elisabeth of Brandenburg (24 August 1510 – 25 May 1558) was a Duchess consort of Brunswick-Göttingen-Calenberg by marriage to Eric I, Duke of Brunswick-Lüneburg, and Regent of the Duchy of Brunswick-Göttingen-Calenberg during the minority of her son, Eric II, Duke of Brunswick-Lüneburg, from 1540 until 1545. She is considered a "Reformation Princess", who, together with the Hessian reformer Anton Corvinus, helped the Reformation prevail in today's South Lower Saxony.
