Biography
Joachim I Nestor assumed power in Brandenburg as a teenager, thrust into the turbulent currents of early 16th-century Europe. His reign was defined by a profound and unyielding loyalty to the Roman Catholic Church, even as Martin Luther's ideas ignited the German states around him. While his own wife, Elizabeth of Denmark, secretly converted to Lutheranism and eventually fled, Joachim doubled down, persecuting Protestants within his borders and aligning himself with Catholic emperors. He was a patron of learning, founding the University of Frankfurt an der Oder, but its intellectual climate was strictly orthodox. His stubborn defense of the old faith created a religious rift within his own family and set a course for Brandenburg that would only be dramatically reversed by his successors.
