House of Leiningen
In 770, Kleinkarlbach had its first documentary mention in the Lorsch codex. In 873 it belonged to the Murbach Monastery. In 1309 it was granted as a fief to the House of Leiningen. After the French Revolution it belonged to the Department of Mont-Tonnerre (or Donnersberg in German) and from 1813 to 1816 lay Kleinkarlbach under Austrian administration, before it was annexed to the Kingdom of Bavaria as part of the "Rheinkreis".
