"Eric II, Duke of Brunswick-Lüneburg (10 August 1528 – 17 November 1584) was Duke of Brunswick-Lüneburg and ruler of the Principality of Calenberg from 1545 to 1584. Since 1495 the Principality of Göttingen was incorporated in Calenberg.
He was the son of Eric I and Elisabeth of Brandenburg. While he was still a minor, his mother acted as Regent and introduced the Reformation in Calenberg, including her children´s conversion. However, in 1547 Eric II declared his reconversion to Roman Catholicism, to the dislike of his mother." - (en.wikipedia.org 30.01.2020)
