In 1526, the abbey was dissolved as a result of the Reformation. Since then, Sonnefeld has been an Evangelical Lutheran parish. The Thirty Years' War destroyed most of the houses and buildings in Sonnefeld and Hofstädten so the reconstruction was slow but steady. It got a big boost from the grant of market privileges by Duke Albert V, Duke of Saxe-Coburg. In 1705, the district of Sonnefeld came to the Duchy of Saxe-Hildburghausen. In 1769, the parish church was rebuilt. In 1826, the district of Sonnefeld was given to the Duchy of Saxe Coburg and Gotha in the redistribution of lands between the surviving Saxon duchies.
