In 766, Wendelsheim (Wenilsheim) had its first documentary mention in the Lorsch codex (other sources refer to a donation document for Fulda Abbey from 841). Celtic finds, however, establish that the area was already settled in prehistory. As with all places whose names end in —heim (cognate with English home), it might have been a Frankish settlement.
Wendelsheim might well have been among the Waldgraves’ oldest landholdings. It is supposed that it belonged to the estate of office with which the Emichonen, as the Salians’ “undercounts”, had been furnished.[3] From 1370, it is evident that Count PalatineRuprecht I held landlordly rights to Wendelsheim. About 1380, the village was pledged to Count Palatine Ruprecht the Young, and from 1438 to 1452 to Count Palatine Ludwig IV.
In 1398 and 1409, Wendelsheim was a Comital-Palatine fief held by Rhinegrave Johann von Dhaun zu Rheingrafenstein. Mediaeval sources describe the Rhinegrave as the village's and municipal area's highest Vogt and rightful chief justice.
From 1475 until the French Revolution, lordship over Wendelsheim was held by the Counts of Salm.
The municipality's arms might be described thus: Tierced in mantle, Or a lion rampant gules crowned argent, gules semé of crosses pattée of the first two salmon haurient addorsed of the third, and azure diapered a fess of the third.
The lion rampant on the dexter (armsbearer's right, viewer's left) side comes from the arms once borne by the Waldgraves, and the silver fess (that is, horizontal stripe) on the sinister (armsbearer's left, viewer's right) side from those once borne by the Rhinegraves. The two salmon are a cantingcharge for the Counts of Salm (Salm means “salmon” in German), who were Wendelsheim's last lordly rulers. The arms are first known from a seal dating from 1775.[5]
The Mikroforum is, as a high-technology park, a major employer. Winegrowing plays an important rôle for the whole region.
Transport
There is a former railway station on the Wiesbachtalbahn in the municipality. There is also a bus service that operates several times a day from Alzey.
