Haderslev marks 500 years of Reformation a decade ahead of Denmark

The southern Danish city of Haderslev has begun celebrations for the 500th anniversary of the Reformation’s introduction—ten years before the rest of Denmark observes the same milestone in 2036, reports DR.

While Denmark officially adopted the Reformation in 1536, Haderslev implemented Lutheran reforms a full decade earlier, in 1526, under Junker Christian—the future King Christian III—who governed the Duchies of Schleswig and Holstein. Inspired by Martin Luther’s opposition to Catholic practices like the sale of indulgences, Christian introduced Lutheran principles in his territories, including Haderslev.

“He essentially made Haderslev the Wittenberg of the North,” said Inge Rogat Møller, a member of the steering group for Reformation 500 Years in Haderslev, referencing the German city where Luther famously posted his 95 Theses. The anniversary will be marked with events throughout 2026, beginning this weekend as part of the city’s annual Duke Hans Festival. Activities include theatrical performances about Luther and the Reformation.

A four-year-old participant, Asta Alby, contributed to the festivities by painting a Luther rose, a symbol associated with the Reformation.
