The Counts Württemberg began acquiring more and more of the village until it fully came under their control in 1425.

From the 15th century to 1938, Erdmannhausen was assigned to the district of Marbach am Neckar, which was dissolved and replaced by Landkreis Ludwigsburg.

[2] Erdmannhausen's coat of arms displays a crosier, in gold, upon a field of blue, below a yellow chief containing a black stag antler [de].

The crosier is a reference to Murrhardt Abbey [de], which owned the Januariuskirche in Erdmannhausen, and the stag horn to Württemberg.

Local public transportation is provided by the Verkehrs- und Tarifverbund Stuttgart.
