Frederick I of Saxe-Gotha

Frederick I maintained and expanded the educational reforms initiated by his father Ernest the Pious. He ensured the continuation of compulsory schooling and supported the training of teachers, solidifying Gotha's reputation for education.

Frederick I enforced strict Lutheran orthodoxy in Saxe-Gotha, suppressing Pietist movements. He issued religious edicts to maintain doctrinal purity, aligning his rule with the confessional politics of the time.

Frederick I enlarged the ducal library at Friedenstein Palace, acquiring manuscripts and books. This collection became one of the significant libraries in Thuringia, supporting scholarship and cultural life.
