ヨハン・カジミール
She married on 4 June 1570 in Heidelberg during the Diet of Speyer with Count Palatine John Casimir of Simmern (1543–1592). August opposed the policies of John Casimir, who was a Calvinist and friendly to France. With this marriage, August hoped to woo John Casimir over to the Lutheran side. However, he did not succeed. The Catholics in Germany regarded the marriage as a provocation against the Habsburg dynasty and an attempt to form a united Protestant front.
