House of Leiningen
As early as 767, Obersülzen had its first documentary mention as "Sulzheim" in the Lorsch codex. Until 1477 it was held by the Counts of Leiningen. Thereafter, and for four years, it was jointly governed by the House of Leiningen-Westerburg and the Electorate of the Palatinate. In 1481, it ended up under the sole lordship of the Prince-Bishop and was placed under the "Oberamt" of Alzey; the "Unteramt" responsible for it was Freinsheim.
