From the german Wikipedia: Around the year 1000, Bishop Heinrich of Würzburg founded a Benedictine convent in Billigheim, which is first mentioned as "Closter Bullikhemb."

The older settlement, which likely predates this, was probably established by a Frankish regional prince from the Bulling family.

In 1238, at the request of the nuns, the convent was converted into a Cistercian monastery and flourished during the 13th century, holding local authority until its dissolution.

The monastery was weakened by the Peasants' War and the Reformation in the 16th century, and was finally dissolved in 1584 by Archbishop Wolfgang von Dalberg.

Following the Reichsdeputationshauptschluss, the Electorate of Mainz was secularized, and the Billigheim estate fell to the Principality of Leiningen in 1803.
