Erdmann August, Hereditary Prince of Brandenburg-Bayreuth


Erdmann August of Brandenburg-Bayreuth, was a member of the House of Hohenzollern and Hereditary Margrave of Brandenburg-Bayreuth.
He was the seventh of the nine children of Christian, Margrave of Brandenburg-Bayreuth by his wife, Marie of Prussia. In fact, he was the third-born son but the only one to survive into adulthood; his two older brothers Georg Frederick and Christian Ernst died long before his own birth.
In Ansbach on 8 December 1641, Erdmann August married the Margravine Sophie of Brandenburg-Ansbach, who was also his first cousin. They had only one son:
  1. Christian Ernst, who became Margrave of Brandenburg-Bayreuth.
Sophie died on 3 December 1646. Erdmann August himself died four years later, aged thirty-five, in the middle of the preparations of his wedding with Sophie Agnes of Mecklenburg-Schwerin. Because he predeceased his father, his son Christian Ernst succeeded as Margrave of Brandenburg-Bayreuth in 1655.
