Early life

On 7 May 1626 in Güstrow, she married Duke John Albert II of Mecklenburg-Güstrow (1590-1636). After his death, she took up regency for her young son Gustav Adolph, as specified in her husband's testament. However, only three days later, her brother-in-law Adolf Frederick I deposed her as regent and guardian of her son and took up those rôles himself. This caused a bitter dispute between Eleonore Marie and her brother-in-law. However, on 4 May 1636, the estates submitted to Adolf Frederick I.
