1497–1546 (age 49)·Duke of Brunswick·Birthday: June 27
Biography
Born into the powerful Welf dynasty, Ernest inherited the Lüneburg-Celle principality in 1520, a time of profound religious upheaval. Unlike many rulers who wavered, he embraced Martin Luther's teachings early and with conviction, transforming his duchy into a Protestant stronghold. His commitment was not merely doctrinal; he became a key military leader in the Schmalkaldic League, an alliance of Lutheran princes formed to defend their faith against the Catholic Holy Roman Emperor. This political and martial defiance, which defined his 26-year rule, helped ensure the survival and territorial entrenchment of Lutheranism in Northern Germany. His death in 1546 coincided with the outbreak of the Schmalkaldic War, a conflict his actions had helped precipitate, cementing his legacy as a pivotal, hands-on champion for the new faith.
