In 1103, Laubach had its first documentary mention. A lordly estate named "Lupach" belonged as of that year to the Ravengiersburg Monastery as the result of an exchange deal with Provost Amselm of Saint Stephen's in Mainz. In 1135, the widow of Burkhard von Honrein (that is, the neighbouring village now known as Horn) transferred her estate in Horn, Laubach and other places “together with the right to assist in filling the pastoral post at the church in Horn to the Ravengiersburg Monastery”.
