Solms-Laubach was a County of southern Hesse and eastern Rhineland-Palatinate, Germany. The House of Solms[1] had its origins in Solms, Hesse.
Solms-Laubach was originally created as a partition of Solms-Lich. In 1537 Philip, Count of Solms-Lich, ruling count at Lich, purchased the Herrschaft Sonnewalde in Lower Lusatia which he left to his younger son Otto of Solms-Laubach (1496–1522), together with the county of Laubach. While Lich and Laubach were counties with imperial immediacy, Sonnewalde remained a semi-independent state country within the March of Lusatia (the latter being an immediate state of the Holy Roman Empire). A later Count Otto (1550–1612) moved to Sonnewalde and built the castle in 1582. In 1596 he also purchased the nearby Herrschaft of Baruth which was also elevated to a state country within the March of Lusatia. The branch then was divided into the twigs of Solms-Laubach, Solms-Sonnewalde and Solms-Baruth.
Solms-Laubach partitioned between itself and Solms-Sonnenwalde in 1561; between itself, Solms-Baruth and Solms-Rödelheim 1607; and between itself and Solms-Sonnenwalde 1627. Solms-Laubach inherited Solms-Sonnenwalde in 1615. With the death of Count Charles Otto in 1676, it was inherited by Solms-Baruth and recreated as a partition in 1696. Solms-Laubach was mediatised to Hesse-Darmstadt in 1806.
The counts of Solms-Laubach still own Laubach Castle and Arnsburg Abbey. Until 1935, Münzenberg Castle also belonged to the estate.
