»Joachim II of Brandenburg. Elector between Renaissance and Reformation«: Elector Joachim II (1505-1571) is the defining ruler figure of Brandenburg in the age of the Renaissance and Reformation. This new publication is the first to trace the entire life and reign of this ruler on a broad source basis; it presents Joachim II as an ambitious power politician who focused on the interests of his dynasty, but also as a mediator between the religious-political camps who opened the Mark Brandenburg to Luther's teachings in 1539/40.
