After the third division of Solms in 1548, Solms-Laubach became a separate principality, with Frederick Magnus I as its first ruler.
Frederick Magnus I was a friend of the Reformer Philipp Melanchthon.
He abolished the inheritance tax and issued a simplified court order, which developed into the Civil Code of Solms.
It is a listed monument and was registered under Heritage Protection Act in 1955.
Frederick Magnus I died in 1561 and was succeeded by his son John George I.
