At the time of the death of his father (1573) Friedrich Wilhelm was still under age; for this, a tutelary government for the duchy was appointed. This was stressed by the Dowager Duchess Dorothea Susanne, because she cannot prevent, however, the Elector Augustus of Saxony -from the Albertine line- was designated as the regent in  her place. In 1586 Friedrich Wilhelm was declared an adult and began his independent government over in Saxe-Weimar. Five years later, in 1591, the Elector Christian I of Saxony died and was succeeded by his eldest son Christian II. Because the new Elector was still under age, the regency of the Electorate was assigned to Sophie of Brandenburg, widow of Christian I and mother of the heir. While she became regent, Friedrich Wilhelm was asked to assist and assigned the title of "Administrator des Sächsischen Kurstaates" (Administrator of the Saxon Electorate). He took residence in Torgau, and neglected the  government of his duchy. These were led by his younger brother John, which had to be taken part -in accordance with the Ernestine House Law- anyway in the government. In 1601 Sophie's regency in the Electorate of Saxony ended with the majority of Elector Christian II, and Friedrich Wilhelm returned to Weimar. Since he died one year later, he did not leave large traces in the history of the duchy. Marriage and children.
