Oberstenfeld originated in the 7th or 8th century, and belonged to the Lichtenberg castle residing above the town.
The Oberstenfeld nunnery was founded in 1016 CE, its patronage was taken over in 1357 CE when the count of Lichtenberg sold the town to the dukes of Württemberg. In 1540 CE it adopted the reformation but remained a part of the Imperial Knights until 1803 CE when it was taken in by the duchy of Württemberg.
The community Prevorst as well as the Lichtenberg castle were taken over by the dukes of Württemberg from the count of Lichtenberg in 1357 CE, (A few years before in (1350 CE) they had acquired Gronau from the Margraves of Baden, and from this time Prevorst belonged to Gronau).
The three villages were conjointly assigned to the de:Oberamt Marbach since 1810 CE. In 1938 CE Oberstenfeld was allotted to the Ludwigsburg district while Gronau and Prevorst became a part of the Heilbronn district. On January 1, 1972 Gronau and Prevorst changed the district and were assigned to Oberstenfeld.
