Hermann II, Landgrave of Thuringia

Hermann II (28 March 1222 in Creuzburg – 3 January 1241) was the Landgrave of Thuringia and the son of Louis IV, Landgrave of Thuringia, and Saint Elizabeth of Hungary.

[1] With Louis's death in 1227, his brother Henry Raspe assumed the regency due to the minority of four-year-old Hermann.

[1] Henry managed to officially succeed his brother after the death of Elizabeth in 1231.

Hermann never reigned and died ten years later; some historians have accused Henry of poisoning the youth.

He was married to Helen, daughter of Otto I, Duke of Brunswick-Lüneburg.
