In 884, Beinheim belonged to theAbbey of Honau, and is mentioned as such (as "Beinenheim") in a document ofCharles the Fat. As a formerlandgrave city with a castle, by the 15th century, Beinheim was no longer head of the Riet.[4]
In 1255, Beinheim belonged to the baron ofFleckenstein, who sold it to themargrave of Bade in 1402 or 1404. The margrave later introduced religious reform, which did not gain much of a hold.[4] In 1497 the margrave sold Beinheim to theCount Palatine. In 1557 the count sold it back to the margrave, who maintained possession until theFrench Revolution. The castle was demolished in 1687.[4]
Bernard Hentsch was elected mayor in 2001 and has held the position since then, re-elected most recently in 2020.[5] Beinheim has 19 municipal councillors.[5]
