Early lifeEdit

On 23 January 1628, at the age of 13, August was appointed administrator of the Archbishopric of Magdeburg by its Chapter to replace the current holder of that title, Christian Wilhelm of Brandenburg. By that time, August had already served three years as coadjutor. Nevertheless, he could not assume his post: on 20 May 1631, after seven months of siege and plundering during the Sack of Magdeburg, the city was taken by the Imperial troops; the Catholic competitor for the diocese, Archduke Leopold Wilhelm of Austria, assumed the title of archbishop and administrator of Magdeburg. The Peace of Prague (1635) confirmed his rule over the city, but three years later, Swedish troops expelled the Habsburg army and restored August as administrator as of 19 October 1638. August finally took full control of Magdeburg on 31 December 1642 after a neutrality treaty was concluded with the Swedish general Lennart Torstenson. He was then able to begin the reconstruction of the city.

In 1643 August was accepted into the Fruitbearing Society at the behest of Louis I, Prince of Anhalt-Köthen.

Duke of Saxe-WeissenfelsEdit

In his will of 20 July 1652, Elector John George I ordered a division of the Albertine territories that was carried out on 22 April 1657 in Dresden. August inherited the towns of Weißenfels and Querfurt and became their first duke.

August also increased his incomes by taking over the administration of the County of Barby during the minority of Count August Ludwig. On 17 October 1659, however, the young count died shortly before attaining his majority. With him, the line of Barby became extinct. A dispute over his lands was resolved in favor of August seven years later (1666). In his will, the duke left Barby to his son Heinrich.

On 25 July 1660, August laid the first stone for his official residence, Schloss Neu-Augustusburg in Weissenfels. This castle was built in the same place as the old one, which had been devastated by Swedish troops. The duke died before the castle was finished.

On 15 July 1667, the sons of the late Duke Wilhelm of Saxe-Weimar offered August the presidency of the Fruitbearing Society. He accepted the office with its responsibility for fostering the work of artists and scientists. His activities as a patron left considerable debts for his descendants to deal with.

Marriages and issueEdit

In Schwerin on 23 November 1647 August married Anna Maria of Mecklenburg-Schwerin. They had twelve children:

  1. Magdalene Sibylle (b. Halle, 2 September 1648 - d. Gotha, 7 January 1681), married on 14 November 1669 to Duke Frederick I of Saxe-Gotha-Altenburg. She was an ancestor of Queen Victoria of the United Kingdom.

  8. Christine (b. Halle, 25 August 1656 - d. Eutin, 27 April 1698), married on 21 June 1676 to August Friedrich of Holstein-Gottorp, Prince-Bishop of Lübeck (son of Frederick III, Duke of Holstein-Gottorp, and his wife Duchess Marie Elisabeth of Saxony).
  9. Heinrich (b. Halle, 29 September 1657 - d. Barby, 16 February 1728); he inherited Barby.
